Are we done with arctic air?

 

Today we have that clipper moving across Canada to our north and we're also going to have a clipper like disturbance moving into Virginia from the  Tennessee Valley. Neither one of these systems is going to bring significant snow to the region The northern disturbance bringing a dusting to an inch or two across part of Pennsylvania New York State into New England. With perhaps 3-4 inches across the higher hills south of the Mohawk Valley, Tug Hill, Adirondacks and higher elevations in New England. The southern disturbance will bring some snow along the Mason Dixon line into southern Pennsylvania, Maryland , Delaware and New Jersey. Snow mounts aren't gonna be significant and will generally range for dusting to an inch maybe two in spots.

The temperatures this week have moderated a little bit from the ridiculously cold temperatures we've been experiencing for the last week to week and a half. But they're still considered below average for this time of year.

High pressure is gonna build in tomorrow and temperatures are going to become a little bit warmer than they are today. The limited lake effect will be continuing and the region will see these disturbances pushed to the east with lingering Snow showers.

Heading into Thursday We will be watching a clipper approach the region Along with a wheat trough moving across. This will bring Scattered snow showers And some flurries to the region Along with more limited lake effect snow downwind of the lakes especially lake Ontario. Thursday night into Friday we will see the bottom dropout and our temperatures are once again going to head into the basement. With this we're going to see a coastal low developed south and east of long island. This won't bring anything significant to the region But it could enhance snowfall a little bit across parts of southern New England and Long Island. Over the weekend It's going to be windy across the region. So wind chills will be adding to that cold.

Weekend temperatures

We are going to cool off a lot again this coming weekend. Then as high pressure builds in temperatures will start to modify next Monday then temperatures turn much warmer for 10th of February and lasting two or three days. During this time we could see temperatures actually trend above average.

I've been talking about the teleconnections The El Nino Southern Oscillation, Madden Julian Oscillation along with the polar vortex and  sudden stratospheric warming. And how these things are pointing at a return of the cold during the second half of February. I think from February 15th onward we're generally gonna see temperatures cool off quite a bit Likely becoming below average overall once again. 

We're moving into that part of winter where what is considered average temperature anomaly climbs near 1° a day. So what is considered below average for February 15th is not necessarily the same below average that we would see on January 15th.

So to answer the question, no we're not done with arctic air masses just yet!
