Monday, January 27, 10:19am
Temp: 8.1°, Chill: -5°
I don't believe we accumulated any snow overnight, although I guess it would have been hard to tell with all the drifting and blowing. I've not seen any reports around here, so my 2" I predicted was pretty much wrong.

What I did get was a 40mph wind gust at 2:52am, right after temperatures began to plummet. We were at 40° at midnight, began a slow slide, and then around 2:30am the bottom fell out. We haven't risen since.

So far today our coldest wind chill was -11° a little before 9am, but expect that to get surpassed sometime this afternoon. We are still hours away from the heart of the cold air entering our region, and when it does we could see very cold readings.

I'll be interested to see two things: 1. if we get colder than we were a couple weeks ago for a base temp. 2. if our wind chills go lower (I don't think they will) and 3. if we go above zero tomorrow (I think we will, just barely).

Monday, January 27, 4:31pm
Temp: 9.5°, Chill: -4°
Our temp actually came up just slightly today after bottoming out at 7.6° around mid-morning, we've been hovering around 10° the rest of the day.

Now that the sun is going down we should see the downward trend. I think -10° is a pretty safe bet tonight, but winds should be light so I don't think we're going to get worse than the -36° wind chill we saw back on January 7th.

It's amazing to see how far reaching this cold blast is. Look at the latest watches and warnings throughout the US:


Two things stick out to me: the enormous area of Wind Chill Warnings, and the winter weather in the deep south. There are areas that will get snow and ice tomorrow that don't know what that is. Some people in the south don't own shovels, and some cities don't have a budget for snow removal.

This cold blast may not be as bad as the early January shot, but it feels like it's much farther reaching.

Monday, January 27, 8:23pm
Temp: 1.9°, Chill: -14°
Ready for fun with models? The Euro gives us an overnight low of -20°:


Skies are clear and temps are dropping by about 1.5° an hour, but -20° seems awfully far fetched.

But how could there be two models calling for it? The latest high resolution RAP has -19° for us at 7am tomorrow:


So maybe, just maybe, we will see historically low temps tonight...

Tuesday, January 28, 9:22am
Temp: -7.6°, Chill: -15°
It's a cold morning out there for sure. We officially dipped down to -12.5° this morning, colder than we experienced on January 7th for sure. But, the wind chill didn't break that bitter -36° mark. In fact the wind wasn't that bad at all this morning, with gusts usually only in the 3-4mph range so the wind chill only reached -22°.

Temps are on the rise this morning and we should make it near zero by noon.

The latest HRRR is calling for a high of 10° today, but I think that's off. I say we reach 8° today and winds pick up some in the afternoon to guarantee wind chills don't get above zero.

AnalogueKid already reported -9.4° this morning, what were some of the other lows out there?

Tuesday, January 28, 11:40am
Temp: 0.6°, Chill: 0°
Right on time, we just made it above zero for the day. But that's where our wind chill sits, too. Hardly any breeze out there, which is definitely a good thing.

Tuesday, January 28, 5:55pm
Temp: 3.2°, Chill: 0°
We're on our way back down for the night and we did not warm up today at all. Our high of 5.2° is the coldest high I believe I have ever recorded on my weather station.

Wind was never really a factor today, which is why our Wind Chill Warning was cut back to a Wind Chill Advisory from now until tomorrow afternoon. Wind chills today hovered somewhere between -5° and 0°.

The south is in the middle of their first "big" winter storm in quite a while, as Atlanta has seen an inch of snow and places like Charleston, SC could have some pretty big icing problems over night. All of this is because of our latest huge cold blast.

Some computer models are aiming at below -10° for the lows tonight, and I actually agree to an extent. I believe it'll go low, especially since we didn't get to double digits today. Cloud cover that poured in around midday should eventually begin to move out of the area and allow another cold night. This is where we could see more cold pockets develop overnight like TheHermit43130 reported this morning.

I think we'll make it just to -10° in the morning. With little to no wind overnight, wind chill won't be a huge issue.

I'll start a new post tomorrow talking about our chances for weekend precip.

Looks like Newark Airport made it to at least -22°F this morning, pretty impressive!

Don't have a weather station, but KDLZ/Delaware airport is close to me and they reported -22 at 3:36 am...shortly before going offline.

My weather station hit -15.9 at 8:18am. Down here the wind stopped blowing at around 2am and has been dead calm ever since. That probably allowed for a pocket of super cold air to settle over Fairfield County.

My thermometer next to the house read -9.4°F this morning. Colder than the last polar vortex, but not as bad as originally predicted.

Well, my gut was spectacularly wrong. -19 at KLHQ. My weather station read -15.5. Dang.

At 10pm the dew point is still only -8. My gut feeling is it won't below -3 or -4 tonight.
