An area of low pressure will quickly move out tonight. Mix precipitation will continue to fall . snow, sleet and rain will continue this evening. Snowfall looks to be around what i expected for areas west of i84 . but inside of 495 a did not account for this much sleet/rain mix. This has greatly reduced the amount of snowfall that will be expected now as well as a very sharp gradient (drop in snowfall from one area to another)
snow accumulations.
0-2 inches east of i95/ inside 128.
2-4 inches between 128 and 495
4-8 inches outside of 495 with areas up to 12 inches.
Precipitations starts to move out from west to east.
After the storm. A cold thanksgiving will be expected. We have to watch a small distrubance that could give southern areas some snow showers and give the area an additional 1 inch of snow.
It then looks to remain in the low to mid 30s friday and saturday as well. Sunday looks to be warmer with highs in the mid 40s 40s.
Monday looks warm with a chance of showers as a cold front moves through later in the day. highs will be in the 50s.
tuesday looks cooler again with highs in the mid 30s

Even though its far out, there is a huge difference in models. gfs shows a very active end of the week possibly with several clipper systems that we will have to watch. the euro shows none of this and gives us warmer temperatures. We will have to wait. Wednesday will be what determines what happens after that. Its far out so alot of time to put it all togeather. Just something to mention since the gfs had this storm down when the euro had to play catch up.
