.DISCUSSION...
As of 222 PM EDT Tuesday...
KEY MESSAGE 1: Aside from some low end shower chances tonight
and some chances in northeastern Vermont Thursday with a passing
backdoor front, conditions will remain dry. Locations that do
receive rainfall will mainly see less than 0.05". Otherwise,
notably dry conditions this afternoon with moderate with cloud
cover and increasing dew points tonight. Then the long wave
pattern is favored to become pinched enough aloft to allow for
two backdoor fronts to move through, one on Thursday and again
on Friday. These fronts will be mainly dry, especially west of
the Greens. Northerly gusts 15 to 25 mph are favored both
afternoons with RH in the Champlain/St Lawrence valleys
approaching 30%. Some very isolated critical conditions for fire
weather may occur. Temperatures will remain slightly below
seasonal averages through Friday before warming back to average
by Saturday. Highs will generally be in the 40s and low 50s
through Friday and back into the mid/upper 50s to low 60s for
Saturday.
KEY MESSAGE 2: A relatively quiet stretch of weather is expected to
continue heading into the weekend and the beginning of next week.
While a few showers may be possible, high pressure overhead will
keep most precipitation chances to our south across southern New
England and the Mid-Atlantic. Relative dry weather is expected to
continue through the beginning of next week, with more widespread
precipitation chances not arriving until Tuesday night or Wednesday
at this time, which may be even later depending on how quickly
ridging across the region breaks down. Temperatures will generally
be near seasonable normals for late April, with daytime highs in the
upper 50s to mid 60s and overnight lows in the 30s to mid 40s.

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Through 18Z Wednesday...VFR conditions continue to prevail across the
region this afternoon, with increasing high and mid level clouds
this evening. Ceilings will continue to lower overnight, with most
terminals expected to see a period of MVFR ceilings after 09Z or and
so, continuing through the remainder of the forecast period. A few
showers may be possible overnight tonight, particularly at KRUT, but
there is low confidence in any shower development or impacts to
terminals to include in the forecast, with ceilings having a greater
impact on aviation. Winds this afternoon have generally be from the
southwest, with southeast winds at KPBG, anywhere from 5 to 10
knots. Occasional gusts up to 20 knots are possible, especially at
KMSS. Winds will continue to be southerly throughout the forecast
period.

Wednesday Night: Mainly VFR, with local IFR possible. NO SIG WX.
