The Polar Vortex going to drop to Ontario and Quebec again next week. You know what that means.
Now that averages are going up, the same air mass will be even more below normal as last time. Just depends how cold and how deep it goes.
And it's still 7 days away so who knows.
And like snj90 mentioned... with the trough being carved out in the East, chances of snow could/should happen.
Here's GFS Upper Flow pattern next weekend. 2 things it says.
1. The gradient is tight and the trough isn't deep so Mid Atlantic doesn't feel the real cold. But a Strong Canadian surface high provides some well below cold air.
2. It doesn't leave as fast as last time.
We'll see.
Here is the anomaly for that same time. PV well below normal in that spot end of February.
Max temp anomaly next Sunday. Figures. We get cold last week. Storm doesnt track up the coast and we warm up mid week. Now we're gonna get cold again without a storm?
If the PV can hang around in southeast Canada March should get interesting.
The above normal temps east of hudson bay is throwing me off here.

Interesting contrast between the Northeastern US and Atlantic Canada. Is that a common setup or are anomalies usually similar? Never thought about it.

There've been times when Maine was well above average and most of the rest of the Northeast was below, so a similar setup to that happens occasionally. Even here, temperature anomalies often miss that far east

That is a very extremely tight temp gradient, NC above average but Maryland below? Then well above temps east of the vortex?

That's true, I forgot about that. Maine sticks out like a sore thumb when that occurs.
pretty common since you got the strong southerly flow on one side and north flow on the other but that much above normal?? being well above normal caught my eye in Eastern Canada. I dont get how if you look at my previous maps the 500mb anomaly is well below normal so how can the surface be well above normal in the area? Unless theres a surface ridge and HP pointing up to Greenland??
Hmmmm, that would make sense why I saw the cold lasting long (blocking)
Also remember this is the afternoon anomaly, not a 3 or 5 day average so the airmass still has to shift east after this.

Yup. Thats exactly what I noticed. I think last time was the same where it was well below notmal in Northeast but North Carolina was just seasonable? Tells me the jet doesnt dig too far south again so the real cold air stays north of Mid Atlantic. We'll see.

It's further north this time actually, last time we got down to 15, and the days before, and following the outbreak, were below average significantly but you are right the departures were not as much as the northeast,the effects of the PV were minimal though once you were south of NC, this time it looks like a more west based outbreak and the effects of the PV aren't felt much further south than Maryland.

What's with the random swath of above normal temps in GA in between two below average periods in both FL and TN?
