Temperatures rose into the mid 50's today, and tomorrow could hit 60 in Keene. Some parts of SNE could see 70 on Wednesday. An intense storm out of the midwest will bring a chance of showers and maybe even a thunderstorm Wednesday evening through Thursday. The low will move off the coast Thursday, bringing in much colder air and changing any remaining precipitation to a snow/sleet/rain mix. There will be a break in the precipitation Thursday night, and then Friday, a secondary low associated with the same clipper will move up the coast toward the region. High temperatures will struggle into the 30's on Friday and for the rest of the weekend. As low pressure bombs out east of Cape Cod, heavy precipitation will affect much of SNE with it being in the form of snow for inland areas including Keene. Right now, the NWS has just started to consider this possibility and has made a very interesting update to the AFD. In addition, the zone forecast includes "light snow accumulations" for Thursday Night, Friday, and Friday Night. I expect an upgrade at least to "moderate" or even "heavy" for Friday night from the evening shift, and think that POPs will be lowered Thursday night.
This could be a very dangerous 4-day storm. We will first have to contend with potential extensive flooding and thunderstorms Wednesday through Thursday, and then a potential major winter storm through Saturday. Remember, it is March and it is New England. It is still winter.
Long term discussion:
Definitely a colder and more stormier solution than I previously thought, however I will stick with my forecast of above average temperatures for March as a notable warm continues to appear imminent for late March. The active weather pattern will calm down next week, and probably the week after that. I'm still expecting a significant winter storm for early April, and below average temperatures.
