Central MD Weather Conditions

storm reports for Maryland

By: cws6196, 3:12 PM GMT on June 29, 2011

As I stated in my update yesterday afternoon, those from Southern MD up through Eastern Baltimore Co received the rain and storms. Most of Central MD was in the clear. As of this writing there are no storm reports listed for MD, with all the current reports coming from VA and WV. If you had storm damage or hail please let me know and I will put in a formal report with the NWS.

The cold front is currently directly over MD, part of the reason for the winds today. But, from now until the weekend the temps will be cool and the humidity low with no chance for rain or storms. Come the weekend temps and humidity levels will rise. Possible rain chance on Sunday, but too far out for me to have any confidence in a forecast. Of course I will keep an eye on things.

Tuesday storms in Maryland

By: cws6196, 1:57 PM GMT on June 28, 2011

Update Tues early evening

The cold front is still over OH although touching W PA. Thus far the greatest threat for storms is in S MD where storm cells to the west have already fired up. As the evening progresses those along the MD/PA line and in S MD will see storms with strong winds, heavy rains and hail. The cold front will pass through later tonight, bringing an end to the storm threat (until the weekend).

So far no watches have been issued. The Weather Phone is updated as is Twitter (@wxmanmd).

original post Tues morning

As I have been mentioning, today looks good for storms. Most of the storm development will not be severe, but a few isolated cells could reach that status. Today will be quite humid with scattered clouds.

DYNAMICS

We currently have a low to the south of us drawing up humid moist air. To the west, over OH at the moment, is a cold front moving toward the area. This, coupled with other upper air dynamics, will come together to give us a shot at storms.

CONCERNS

If strong cells do develop you could see heavy rain, strong wind and hail. Most of us will have your typical summer thunder storm, though. The Severe Prediction Center in OK places our area in a 2% chance for tornado development, 5% probability for strong winds, but in Southern MD that probability is 15%, and a 5% probability for hail.

TIMING

All of Central and Southern MD will be involved in this system, and although timing is not an exact science (many dynamics have to come together at just the right time), I see most of the area experiencing storms after 2:00 pm lasting until around midnight or so. I do see these storms as the pop up type, so keep an eye on the sky for development.

ALERTS

I would not be surprised to see the NWS issue thunderstorm watches, but thus far nothing has been issued. I will keep the Weather Phone (443-470-9804) updated as well as "play-by-play" posting on Twitter (@wxmanmd) or www.twitter.com/wxmanmd (no registration needed). I will post updates, as necessary. Stay safe and enjoy the beauty and power of nature!

update on early week storms

By: cws6196, 2:20 PM GMT on June 27, 2011

Some of us experienced rain showers last night into the morning hours, especially those in Southern MD. They were light, but still a surprise. Today most of the area will be under some percentage of cloud cover, which actually is a good thing for those who do not like storms. As I see it, the cloud cover will inhibit high heating of the day, therefore keeping the chance for convection and instability low. But, do not rule out the chance for a scattered storm later today. Keep an eye on the skies.

For Tuesday, I see the chance for storms greater as the humidity levels will be higher, moisture will be brought in from the coast, and an approaching cold front in the evening all add up to storm creation. The storms should form later in the afternoon, and the greatest threat for these storms will be heavy rain and strong wind.

After Tuesday the rest of the week will be nice; no rain, low temps and low humidity. This changes come the weekend when the temps and humidity rise, along with the chance for storms. Another cold front comes through Sunday, so I will be watching for storm potential. But that is too far away for much confidence.

I have the Weather Phone (443-470-9804) updated as well as my Twitter (@wxmanmd). Enjoy the day! If conditions change I will let you know, but keep an eye on twitter as there I post more quickly and more frequently (www.twitter.com/wxmanmd).

could we ask for better?

By: cws6196, 2:21 PM GMT on June 26, 2011

Could we ask for better weather? Not too hot, not too cold ... Today should be the same as yesterday, so enjoy. The temps will be moderate with only slight humidity, so get out and enjoy (while it lasts). We will have clouds later this afternoon into the evening, but no rain from them. Come Monday and Tuesday we are looking at the potential for storms.

DYNAMICS

Today, high pressure dominates the area, bringing us this great weather. As it moves off shore to the east, the clockwise rotation will draw in moisture from the ocean, thus moistening the atmosphere on Monday. As this occurs there will be upper level atmosphere 'disturbances', when coupled with the moisture could produce thunderstorms. The heating of the day Monday will make the difference, as the warmer it is the more unstable the atmosphere due to rising warm air. And the way it looks for Monday, there wont be much in the way of cloud cover. Come Tuesday we add an approaching cold front into the heat and moisture mix and *poof* thunderstorms.

TIMING

Timing is typically an unknown in these dynamics as we have to wait for the proper heating and rising of the air coupled with the right amount of moisture. But, looking at Monday we should be clear of anything until later in the afternoon and evening. Tuesday our chances are good for rain/storms most of the day, but it does depend on the conditions from Monday and the speed of the advancing cold front.

CONCERNS

At this moment my concerns from the storms are strong winds and possible hail, but I will refine this tomorrow when I better know the dynamics.

UPDATES

I will keep my Weather Phone (443-470-9804) updated as well as my Twitter (@wxmanmd), which I update frequently each day. For those on my text message service you will get updates as to watches/warnings issued. If others wish to sign up just let me know. Today's lull in the weather could be a good time for you to spread the word about this blog and to sign up for my email weather list. Leave me a comment here or email me through Weather Underground. I appreciate your support and hope you have a great day!!

storms on the 1st day of Summer

By: cws6196, 3:41 AM GMT on June 21, 2011

Happy Summer to all!!

Portions of Maryland, especially south of Baltimore, are in need of rain, and this they have been receiving. Come Tuesday and Wednesday most of Maryland will receive rain. As a warm front pushes into the area, becoming stalled over the MD/PA line we will see chances for rain and thunderstorms Tuesday and Wednesday afternoons. The heating of the day will play a factor in storm development, and while both Central and Southern MD can see storms, this round of action, especially on Wednesday, will be more likely North of Baltimore and closer to the MD/PA line.

Storms that do develop have the potential for heavy downpours of rain and strong winds. Keep an eye on the sky for rapidly developing storms. I will keep the Weather Phone (443-470-9804) updated as well as Twitter (@wxmanmd).

Father's Day weather

By: cws6196, 2:18 PM GMT on June 19, 2011

A Happy Father's Day to all of you out there!! Today's weather looks to be the same as the past couple days, nice with a chance for rain and thunderstorms. Nothing severe and the storms will be scattered. Most, not all, of the activity will be south of Baltimore City. As you are outside keep an eye on the skies for rapidly developing systems.

I will keep the Weather Phone (443-470-9804) updated as needed as well as posts on my twitter (@wxmanmd).

quick note

By: cws6196, 2:03 PM GMT on June 18, 2011

Just a quick note to say today and tomorrow will be similar to the last couple days with the chance for thunderstorms and rain later in the afternoon and evening. As we have seen, these storms are quick to form, scattered and typically not intense. Again, I do not foresee any issuance of watches/warnings, but still keep an eye on any storm cells that do develop.

I will keep the Weather Phone (443-470-9804) updated as needed, and continue to comment on twitter (@wxmanmd). Enjoy the weekend!!

same as yesterday

By: cws6196, 1:55 PM GMT on June 17, 2011

Today's weather will mimic yesterday's weather, with the exception of those North of Baltimore City who could see showers begin after 1:00pm (cells are now moving in from WV). The low is still moving east with the associated cold front, so yesterday's dynamics remain in place.

Rain and storms will be more prevalent later in the afternoon and through the evening. Like yesterday, most will not be severe, although, isolated severe cells are always a possibility (as some last night were severe). I don't foresee any watches/warnings being issued, but will let you know if they are.

I have the Weather Phone (443-470-9804) updated as well as Twitter (@wxmand).

it had to end

By: cws6196, 4:09 AM GMT on June 16, 2011

Well, we knew it had to end sometime; the boring (...nice...) weather is coming to end. The temps will still be nice for this time of year, but there is now a chance for rain and thunderstorms the next couple days.

As Thursday progresses we will see a warm front move into the area from the South and an advancing cold front and low pressure system from the Great Lakes. As the cold front and low approach, they will interact with the warm front - hence rain and storms. These storms should not be severe and there may not even be any watches issued.

Timing is tricky, but for Thursday I would say we could see thunderstorms any time after 1:00 pm lasting into the evening. Friday we have a chance for storms all day, but these storms will be scattered. The rest of the weekend looks fine and there is a warm up for us next week. No issues in the tropics to concern us, so all in all not bad for us.

I will keep the Weather Phone updated as well as Twitter (@wxmanmd). I continue to encourage everyone to have multiple forms of alerts combined with my service, such as a weather radio, free alerts from http://www.emergencyemail.org/ or free software from a local developer found here http://www.wxspots.com/ (it provides alerts and so much more! I use it). Stay safe out there!

Sunday storms

By: cws6196, 1:53 PM GMT on June 12, 2011

original post Sun June 12 morning

Yesterday's storms went off as planned, although the storms in Central MD were a bit more north than anticipated. If you wish to see a list of storm damage reports here is the link: http://www.erh.noaa.gov/lwx/products/?prod=LSR

Today's weather will be same as yesterday since the same dynamics exist. The cold front moving in from OH is closer to the area and will cross us later this evening. Ahead of the front is the chance for storms.

TIMING

Today I will push back the start time for the storms from yesterday's time frame, looking today for storms to start anytime after 3:00pm into the evening.

THREATS

The main threats are strong winds and hail.

LOCATIONS

Today, different from yesterday, I feel Southern MD will have the brunt of the storms, but that's not to say storms wont form elsewhere, so everyone in Central and Southern MD need to keep an eye on the sky.

I will keep the Weather Phone and Twitter (@wxmanmd) updated. Enjoy the day!

Storms Saturday in Maryland

By: cws6196, 2:56 PM GMT on June 11, 2011

update Sat June 11 early evening

There is a good looking line of storms that has been growing over the past hour or so just West of Frederick. Assuming the line stays together, and with the cold front approaching I believe it will, Baltimore Co from the City North could see rain and storms in 90 minutes or so (about 8:00-8:30). Of course this is just an estimate. I will keep you posted.

update Sat June 11 late afternoon

As I write this Southern MD is experiencing strong thunderstorms with lots of lightning, heavy rain and strong winds. As these cells progress to the E more are forming to the W in VA. Central MD is in the clear at the moment, but scattered cells are forming in the West as the cold front is moving through OH.

Thus far the only watches/warnings are for St. Marys and Calvert Co, but that may change as the evening progresses. I will keep the Weather Phone and Twitter updated.

Sunday we will experience a similar weather day to this one, but more on that later.

original post Sat June 11 morning

Even though today will be cooler (relatively speaking), the chance for storms is enhanced, and these storms could be severe. We have a cold front moving in later today, and the remnants of the boundary that effected us yesterday is still along the MD/PA line. These combos along with the temps lead to the chance of storms (as well as other upper air features I wont bore you with at this time. If you really want to know just email me).

TIMING

These storms are hard to time, but most should experience storms after 5:00pm today, but as of this writing there is a rogue storm cell near Towson (the Palin storm cell). The strongest of the storms will be later in the evening.

CONCERNS

Strong winds and hail are the main feature for these storms, yet given the wind profiles, I do not see any tornado threat.

LOCATIONS

Both Central and Southern MD are at risk for these storms, although I believe the strongest of the storms will be in Central MD into the Southern PA. Not to say others wont see storms, so everyone should be aware of what is happening.

Thus far there are no watches/warnings issued, but I see that changing as the day progresses. I will keep the Weather Phone (443-470-9804) updated as well as my Twitter (@wxmanmd) where I post constant updates. You don't need to register for twitter to see these posts, simply go to www.twitter.com/wxmanmd Keep an eye on the skies, and feel free to send me storm updates, damage reports, by comments here or leave on the Weather Phone.

more heat & storms

By: cws6196, 4:24 AM GMT on June 09, 2011

The heat advisory is in effect for Thursday (today) since it will be hotter than it was on Wednesday. The humidity will be high making it feel in the 100s once again. As a cold front is moving into the area later in the day, we can expect scattered storms to form ahead of the front. The storms could occur anytime after the late afternoon. As with storms of this type, timing is not easy to nail down, so keep your eyes on the sky for any development. The main threat from these storms will be wind. I would not be surprised to see thunderstorm watches issued, but we shall see.

The somewhat good news is that Friday will be relatively cooler, although the humidity will still be high, plus a chance for storms continues throughout the day Friday. I just returned from a trip to Denver and there is still snow up in the mountains; just think, not too long ago we were digging ourselves out ...

I will keep the Weather Phone (443-470-9804) updated and as always I update Twitter (@wxmanmd) multiple times in a day.

Sunday potential storms

By: cws6196, 1:53 PM GMT on June 05, 2011

The storms last night weren't severe, but we did get some rain (it was getting dry). Today will feel a bit more humid than yesterday, but still a nice day to be outside. There is a chance today for more rain / storms, but most of us will not see strong storms. The strong storms will be bordering Southern MD, but should stay in VA. But, keep an eye on the skies.

Enjoy the day!! Follow me on Twitter as I post about the weather everyday throughout the day (@wxmanmd).

weekend weather

By: cws6196, 1:56 PM GMT on June 04, 2011

This is a quick update to first say - enjoy the weekend and the quiet, perfect weather (boring). There is a SLIGHT chance for storms late this evening into Sunday, but to be honest, nothing that should ruin weekend plans, hence I haven't mentioned this sooner. IF storms form they wont be severe and will be scattered. If there are any changes to this I will send an update.

Just to note, there are two areas of interest in the Atlantic and the Gulf, neither of which would have any impact on us at all.

During this boring weather continue to follow my Twitter (@wxmanmd).
