.DISCUSSION...
As of 147 PM EDT...A cold front has passed through the forecast
area and is dropping southward across the northern mid Atlantic
States. Behind the boundary, winds have been breezy, with some
northwesterly winds gusting up to around 20 mph at times.
Visible satellite imagery shows mostly clear skies, with just
some lingering cu mainly for southern and eastern areas).
Dewpoints have been slowly falling today, as drier air continues
to work its way into the region from the north.
Surface high pressure will be building southeast towards the
area from southern Canada for tonight. Winds will be diminishing
this evening, although a slight breeze still may occur in spots
even into the overnight hours. With the clear skies, diminishing
winds and dry air mass in place, overnight lows will be rather
cool thanks to the good radiational cooling. Have leaned towards
the lower end of the blended guidance for tonight, with
overnight lows in the upper 20s to mid 30s across the southern
Adirondacks. Frost/freeze headlines remain in effect for these
areas, as growing season is still officially going for the
entire area. For the the remainder of the area, overnight lows
will be cool, with values in the upper 30s to mid 40s.
Over the weekend, the high pressure area will slowly drift
across the North Country and into New England. This will
continue to keep dry weather in place, with a mostly clear sky.
Daytime temps will be a little cooler than recent days, but
still very comfortable in the 60s to near 70 on Saturday.
Another night of good radiational cooling is expected and more
frost/freeze conditions are possible on Saturday night for the
Adirondacks and perhaps the upper Hudson Valley as well. More
frost/freeze headlines will likely be needed. Temps will be
slightly milder on Sunday, with daytime temps in valley areas
reaching into the 70s.
Some much needed rainfall may finally arrive during next week,
although there remains a lot of uncertainty regarding exact QPF.
A northern stream shortwave will be moving towards the area from
the Great Lakes for early in the week, although how it interacts
with another upper level low over the Mississippi Valley will
determine the best timing for precip and just how much occurs.
For now, will side close to NBM POPs and show chance values from
about Monday night through Wednesday. Latest NBM doesn`t show
much potential for significant rainfall, which is much needed,
as the probability of seeing over 0.50" is under 50 percent.
Still, any rainfall would be helpful and some light rainfall
looks to occur, especially for northwestern areas, by the middle
of the week. Temps will continue to average close to normal,
with daytime values in the mid 70s and overnight lows in the 50s
for much next week.
