Long term /Friday night through Tuesday/...
as of 354 am EDT Wednesday...as ridge axis sets up near
Bermuda, several pieces of vorticity will move over the
northeast, resulting in multiple days of chances of rain
showers. Models continue to show brief period of dry weather
over the north country Saturday night into Sunday before
strengthening low pressure system brings warm air advection showers Sunday
night. Expect frontal boundary associated with the stacked low
to affect the region Monday night. With precipitable waters over 1.5 inches,
still looking at periods of heavier rain along with gusty winds
due 850mb jet of 40-50 kts or more jet. GFS continues to show
500-1000j/kg MUCAPE in the St Lawrence Valley on Monday, which
could help initiate convection. Precipitation chances continue
on Tuesday as the base of the mid-level trough moves over the
region. Precip begins to taper off late Tuesday night into
Wednesday morning.
