Spring has sprung but winter will claw back

And as called on the blog, as part of the shortest update in history, we really did have a spectacular stretch of weather which provided for some great spring skiing. Thursday will be the last of such days as temperatures on the mountain again climb well into the 50's along with some sunshine. Friday however will bring the beginning of a very abrupt change. Both colder weather and clouds will mark what will be the start of a major pattern amplification. Talk of "amplifications" and east coast storms go hand and hand and much of Vermont will see an impact from a storm which will gather some strength across the Plains Thursday and advance eastward Friday. Temperatures are likely to be a bit warm at the surface to support snow and precipitation is likely to start as some rain on Friday. The rain will be periodic in nature but will continue through early Saturday along with temperatures in the 30's.

The longwave pattern will continue to amplify on Saturday and will allow the storm system to transfer much of its energy to the Atlantic Coast. This will also allow colder weather to advance both east and south into interior New England. By early Sunday temperatures both at the surface and aloft are cold enough to support snow but the storms organization that has yet to be answered. Specifically it is unclear whether we can tap into the remaining available moisture and get a significant period of snow out of this before the storm advances out to sea. From my perspective it seems very possible. Any snow is also very capable of accumulating later Sunday into Monday and at the very least conditions should be unstable enough for snow showers.

Winter will certainly make a splash in the form of temperatures on Sunday and Monday as temperatures are unlikely to climb much above freezing during the day. Thereafter, temperatures will modify very quickly and so will our spring conditions. 60-degree temperatures are again possible during the day by the middle part of the week.
