.DISCUSSION...
As of 243 PM EDT Monday...
KEY MESSAGE 1: GOES-19 visible satellite depicts a narrow moisture
corridor associated with a weak cold front stretched across the
region this afternoon. While most of the radar returns have ended up
being virga, some locations in the St. Lawrence Valley have been
able to pick up a few hundreths of an inch of rainfall. By and large
however, many locations will remain dry with little to no measurable
rain from this frontal system, especially those in Vermont where
dewpoint depressions are 10-15 degrees. A few places along the
northwest facing slopes of the Adirondacks and northern Greens,
including Jay Peak, could a few sprinkles though due to orographic
influences. Winds will turn to the north-northwest as the front
moves through this afternoon advecting sharply colder air and some
briefly gusty winds this evening from Canada. As nocturnal cooling
begins after sunset this evening, winds will briefly increase in the
northern Champlain Valley up to 25 MPH or so between 7-10 PM. Winds
will weaken towards calm thereafter. Tonights lows will cool to the
upper 20s for many locations with a few locations hovering around
the freezing mark in the wider valleys; coldest locations will be
across northern New York and the Northeast Kingdom. Tomorrow will
feature sunny skies with continued cool high temperatures struggling
to reach the upper 40s. The coldest night of the season arrives
Tuesday night under strong radiational cooling. Overnight lows may
approach some records for Montpelier and St. Johnsbury, with records
elsewhere residing in the 10th percentile or lower. Temperatures
will drop to the teens across the Adirondacks and low 20s elsewhere.
Temperatures slowly rebound Wednesday as high pressure and south
winds help to moderate our pattern. Temperatures will warm to the
low to mid 50s.
KEY MESSAGE 2: Low chances for some showers on Thursday night as a
front crosses our area. With center of the low passing well north of
our area, not a lot of strong forcing with this frontal passage. If
we have precipitation, it will be light. Then we once again expect
mostly dry and seasonably warm weather for Friday and Saturday as a
ridge of surface high pressure builds into the north country. Some
models indicate increasing chances for showers early next week, but
not a lot of model consistency in that timeframe at this point.
