The system that brought the record-breaking snow from Louisiana to the Panhandle of Florida into the Southeast is pulling away, but not before clipping areas like the Jersey Shore with some very light snow.

We have high pressure taking charge, providing the vast majority of the region with clear skies. The lake effect snow is still falling, the bands are weaker and should taper off during the afternoon. I ended up with a total of 6.4 feet for the event. There is even a bit of ocean effect snow falling in parts of the Coast like Cape Cod.  We’ve been dealing with this arctic blast for a few days, but that is going to start lifting out of here later this afternoon into tonight. So, we will see temperatures much closer to seasonal tomorrow and over the weekend. The breeze will calm down over the next couple of days, making it feel fairly nice.

We have a few shortwave troughs out over the northern Plains into the Upper Midwest, these are going to rotate through the region over the next few days, bringing a few snow showers and flurries, any accumulations should be generally very light, there will also be lake effect and lake enhanced snow coming off the Great Lakes, but this will also be light, and nowhere near what the snowbelts have just gone through.  The biggest disturbance will move through on Sunday. Low Pressure will pass to our north, ahead of this, southwest winds will increase temperatures a to slightly above average for this time of year. Monday a trough will be pushing down out of Canada. This will keep a storm system to our south. But northern Parts of the region could see a few snow showers as the trough dips south.  Tuesday and Wednesday will see more shortwaves move through keeping the threat for a few snow showers around. Wednesday will see a disturbance pass to our north; milder temperatures will be pushing in from the south. So, Pennsylvania, Maryland, Delaware, New Jersey and southern New England will likely be rain with the higher elevation seeing a mix. For those north of there, some snow/mix can be expected.  Pass midweek, the pattern is going to change to one that is much milder for the start of February. During winter 2024-2025 we have seen several polar vortex events where it stretched, bringing several cold air invasions. We’ve seen the high latitude blocking and PV duke it out several times, which has led to these back-and-forth weather conditions we’ve seen. The AO is looking to become positive. Which will make it much harder to get much in the way of blocking. I don’t think we’re done seeing the PV stretch trying to bring in colder during February; but the question will be the blocking; I think blocking will be hard to come by during February. So, while we could see some more cold events during February, I don’t think they will be the super cold outbreaks we’ve seen at times this winter.  I don’t see any major storms over the next 7-10 days. Could we see a major storm or two during February? Yes! But that will very much be depending on timing of the systems, trough axis and extent of blocking at the time.
