It was obvious at 6pm why wait until 9 to update?
NEAR TERM /THROUGH SATURDAY/...
9PM Update:
Pretty impressive area of snow moving across northern MA at this
hour in response to a weak cold front moving west to east
through the region. Pretty impressive estimated snow ratios
between 15-1 and 20-1. With temperatures below freezing, it wont
take much QPF to get a quick coating to inch of snow. Have seen
several reports of grassy surfaces being covered with snow and
even some pavement. This area of snow is moving ENE and should
be offshore by midnight.
6 PM Update:
Short wave trough moving across PA this evening and generating
scattered rain/snow showers downstream across eastern NY into
western CT/MA. Lots of low level dry air across SNE with current
dew pts in the 20s, yielding cloud bases in the 5000-8000 ft.
Thus, much of this activity is drying up as it traverse SNE.
Hence, most locations remain dry this evening, with little if
any impacts (sprinkles and/or flurries).
Winds across the region this evening are WSW ahead of the short
wave. Later tonight, behind the short wave, winds will shift to
the WNW and CAA will commence, yielding a chilly night with lows
in the 20s most of the region, along with blustery west wind
developing late. Earlier discussion below.
