DISCUSSION

As of 238 PM EDT Monday...

KEY MESSAGE 1: A cold, dry airmass is replacing our recent wetter weather regime as upper level ridging shunts the primary storm track northeastward into Canada. Afternoon cloud cover will dissipate with loss of surface heating leaving clear skies and light winds in place overnight. This will be an ideal setup for radiational cooling resulting in a quite cold cool off overnight into Tuesday. Lows are favored to be in the single digits to teens for the Adirondacks and northeastern Vermont with upper teens and 20s elsewhere. Very dry conditions will help temperatures rebound tomorrow into the 40s and low 50s while supporting low RH ranging 25-40%. Fortunately, winds will be light and soil moisture will remain high enough to keep fire weather concerns at bay.

A weak trough will pass Tuesday evening into Wednesday supporting some elevation dependent showers. Most guidance keeps shower coverage minimal, but some CAMs do show a few showers possible for lower valleys. Will keep the forecast pointed towards drier solutions unless there is a larger shift in ensembles or more CAMs join the few that are showing wetter solutions. Temperatures moderate back to seasonal averages Wednesday with flow turning more southerly. Will keep an eye on Thursday for potential in an uptick in winds will a few models suggesting a backdoor, mostly dry front dropping through the region.

KEY MESSAGE 2: A closed upper low centered over the Canadian Maritimes will bring relatively dry and seasonably cool temperatures to the region for the end of the work week. High temperatures will generally be in the mid 50s to low 60s. Chances for precipitation will increase heading into the weekend as the upper level low shifts eastward, although there is still a lot of uncertainty regarding the details at this time given model spread and pattern evolution. Despite the shower chances, seasonable temperatures are expected to continue into the weekend and beginning of next week.
