February 3 2023

Saturday Morning

I get it! We have not had much winter other than these brief bursts of arctic air and a few days of headlines about the Polar Vortex. The reality is that weather phenomenon did clip the Northeast US and resulted in new weather records at Mount Washington in New Hampshire. This was already known to have the World’s Worst Weather.

I want to highlight what they experienced, the current weather there and here, then focus on our big warm up.  I also want to highlight that there is more winter ahead and the models are trying to show something as soon as next weekend.

Polar Vortex- Saturday Morning

This is the location as it exits into the North Atlantic.

High Pressure is passing through our region today. That will keep the wind calmer and sky mostly sunny. A warmer air mass will be racing in over the next few days.

Looking Ahead

Jet Stream Saturday To Saturday

The Polar Vortex departs and a large ridge builds in very warm temps next week. This will be followed by another colder impulse next weekend.

February 4 weather jet stream forecast


Snapshot Next Weekend

This impulse will have a colder pocket with it and may try to bring in a winter component to the storm complex.

Thursday To Saturday

The storm pattern does ride the warm air with rain, then a possible last wave shifting south with colder air and maybe inland snow.

February 4 weather storm rain next week

Next Weekend Snapshot

Please keep in mind that this is an 8 day outlook, but there has been some consistency with yesterday to bring in a weather event with colder air.

The more reliable ECWMF (European) Model is the more robust plot and worth watching. I will keep tabs on it.

February 4 weather storm next weekend


7 Day Forecast

A quick warm up begins tomorrow and as often is the case, we get the other extreme of warm air next week. This will bring in rain at the end of the week, but the longer range does bring winter back next weekend.
