Here Is a look at the current surface chart and regional radar.
The surface chart and radar Shows we have high pressure nosing in out of Canada With yesterday's arctic front to our south and east. The vast majority of the region today is dry But we do have that disturbance moving across North Carolina, With its precipitation field extending into Maryland and Delaware. Southern Maryland including Washington DC and southern Delaware will have a chance for mostly light rain/drizzle, but there could be some light snow and a mix of some sleet or freezing rain. So accumulation of rounded trace is possible for places like DC.
On the satellite we can see New York State and New England is seen mostly sunshine today While Maryland Delaware New Jersey extended into Pennsylvania it seemed more in the way of clouds. Temperature today are going to be frigid, with daytime temperatures in our southern and major metro areas in the 20s into the 30s, interior parts of the region are seeing temperatures in the teens and 20s, While the northern areas see temperatures in the single digits into the teens. Tonight temperatures are going to turn much colder.
For tomorrow high pressure is gonna pass over head, allowing for very cold temperatures during the day. Then a clipper with a weak trough will move through during the afternoon into tomorrow night. Bringing a chance for a widespread light snow showers. General snowfall accumulations of 1-3 inches across northern Pennsylvania, much of New York State into northern and central New England. With the areas like the tug hill and higher elevations across northern New York State and northern New England possibly picking up 2-6 inches. Tuesday night we will have a warm front approaching ahead of this warm front We could have some light snow along with some sleet and freezing rain. But then as temperatures warm the snow and mix will change over to more in the way of rain in the lower elevations, But the higher elevations will likely stick with a mix to snow.
For Wednesday New York State and northern and central New England will see widespread snow in the morning , This will likely change over to light rain in the lower elevations during Wednesday afternoon. But we will be likely seen lake effect falling downwind of the Great Lakes. Our next quick moving clipper will approach and move through later Wednesday afternoon into Thursday dragging another arctic front through the region
Thursday We are going to be under the influence of another arctic air mass. There will be a good chance for heavy lake effect snow to be falling downwind of the Great Lakes.
Friday high pressure is going to briefly build in. But then for Friday into Saturday we will have another quick moving system moving through. Again this will be bring a chance For light snow to southern parts of the region. The system will be pulling away Saturday afternoon Allowing for clearing to develop. But we are still likely be seeing some lake effect falling down wind of the Great Lakes. Sunday the active pattern continues with another weak trough moving through, bringing a chance for light snow showers and flurries. The lake effect is going to continue to be falling down wind of the Great Lakes. Over the few days the lake effect is falling it is going to be meandering around depending on the wind currents. This will help keep snow amounts totals down to manageable levels. But area southeast of lake Erie and lake Ontario could end up seeing quite a bit out of it. Monday we'll see high pressure built in overhead.
This week we're generally going to be experiencing a lot of cold. I think overall This cold active pattern we're in is gonna stick around for quite some time. But as I said yesterday I think we'll see the pattern relaxing little bit around middle of December in towards Christmas and then I think we're going to get cold again with generally snowy conditions prevailing as we move into and through at least the first half of January. The pattern we're in is very progressive with a zonal flow (west to east). With the pattern being active we have been dealing with lots of little to moderate snow events. Currently I don't see any big storms in the pattern Just a basic continuation of what we've been seeing. But winter is just starting, And there is plenty of time to see a few big storms impact the region, as this lack of upstream blocking won't continue all winter. All in All, the pattern I discussed in the winter outlook a few months ago seems to be holding up very well.
