Quoting weathergeek5:
Storms have passed nothing too much here just a noisy storm and torrential rains. I think we have a surplus of rainfall now. The sun is out now so I dont know if that will stir up more convection.

Still 1.27inches of rain below normal here for the year.

Good morning Bliz. Hope that the sun is shining brightly wherever you are. I'm ready to cry 'uncle' here. Rain, rain and more rain. Since Wednesday we have had over 3", over 1.5" since I went to bed last night. Well, the rain gauge read 1.5" this morning and it's been raining buckets for at least the last half an hour.

The forecast is threatening sunshine for the entire next week but things can change quickly. Last time we were forecasted a week of sun, we ended up with three days worth. At the moment I'm more than willing to accept three days of sun! ;}

This was just released:

... Thunderstorms with heavy downpours moving east across the
Maryland Eastern Shore...

At 955 am EDT... National Weather Service radar showed an area of
thunderstorms moving across the Maryland Eastern Shore toward
central and northern Delaware and southwest New Jersey. The storms
should cross Delaware and move into southwest New Jersey by around
1100 am. The storms were capable of dropping in excess of one-half
inch of rain, were generating occasional cloud-to-ground lightning,
and could cause brief wind gusts of around 25 mph.

Please move indoors until the storms pass. Some ponding of water and
some roadway flooding is possible in poor drainage areas, so if you
are driving and encounter water on roadways, please do not try to
cross. Find an alternate Route.

Good morning Bliz,

Oh I see your weather is like my daughter's in West Chester, cold and rainy.

Seems like it rains in eastern PA every other day... I know she is so wanting to come back to Florida or at least someplace that has nice weather! LOL

Hope you have a great weekend!

Happy Weekend Graphics

**GFS is advertising a potential Severe Weather Outbreak sometime next Friday. High CAPE values for much of the Northeast and Mid Atlantic ranging from 1000 to 3000j/kg. LI values range from -2 to -8. Something to keep an eye on as the 6z today has been the most robust.**

We got nailed around 1800.

We were getting frequent strong lightning before the slow moving storm front. The wind picked up and the sky turned a greyish green. The power went out and the local volunteer fire department sirens were going off. Right over our heads, just to the northeast we watched a rotating white gray cloud come closer to the ground in the shape of a wedge. We gathered up our two cats and high tailed it down to the basement. I wish I had the presence of mind to take a video. Darn.

Just about 5 miles to the southeast, there are reports of trees down. A little further away, Accuweather confirmed a touchdown. It was probably our funnel cloud but who knows. There's lots of flooding in the area, up to 3' with the hilly terrain. Friday looks really nasty.

Today we had a wsw or sw wind off the ocean. However it was originating in a fairly warm air mass so the ocean did temper it somewhat. We had probably temps into the low 70s this afternoon. Dew points are lower than the ocean temps so fog is not expected tonight. I do think that the models as of 18z runs are too far se with the track of the Northern Plains low. The first low should track to our south bringing the rains, but then as the then Great Lakes low strengthens so should the southerly winds and pump up the air mass for storms from Friday to Saturday.

patch,

yeah the whole complex seems to be heading more southeast. just went outside to measure the manual gauges. 1.09" so far. wonder how the storms and heavy rain will interact with the marine layer once they cross the laruel mountains? lots of flood advisories up this evening. wouldn't be surprised to start seeing those change to flash flood warnings like some counties out in the pittsburgh forecast area.

Mason - this month for sure has been a bit strange. we haven't had very many days of warm temps with the sun.

you may be in better shape then me being further north for that batch of t-storms. could be some heavy rain. i've hit 60F so far today which is crazy for mid june. nws said the min max record for this area is mid 50's so we're not too far off.

thats exactly what i was thinking Blizz would be saying geek. a marine layer infiltrated the lower sus and it screwed up the forecast.

a breeze came with the marine layer. i think it is typical for this time of year to have a day or two like this

It was nice from 9am to about 3pm then fog and drizzle rolled into the area. Hopefully we get rid of this Maritime High pressure ridge and warm weather can expand northward as the Bermuda High flexes its muscle as we head into summer.

Here in the Allentown area we got walloped by a severe thunderstorm around 4:30 p.m.

3/4 inch to 1 inch hail, wind, and I got 2.44 inches of rain in just 15 minutes. Lots of streets closed due to flooding, downed power lines, and trees. It just may have been the strongest storm I've seen in the last 20 years in this area.

No rain for Campbelltown yesterday. It was a lovely day with a breeze in the evening from the storms to my north and south.
yesterdays high 83.0F
low 64.2F

A beautiful start to the day. Bright blue skies.

the last few days an acrobatic biplane has been doing tricks in the area and a WWII US Army plane must be giving tours. I live a hop skip and a jump from Riegle Airport.

Special weather statement for Saturday 6/13/2009:

. Heavy rainfall this afternoon...

Numerous showers and scattered thunderstorms have developed today
and will continue through the afternoon. The showers and
thunderstorms are very slowly and can contain very heavy rainfall.
Because this rain will occur in such a short amount of time, local
roadway flooding may occur very quickly. Be alert for changing
roadway conditions and do not drive through high water.
