.DISCUSSION...
KEY MESSAGE 1...Multiple of waves of wintry precipitation may cause impacts to
travel tonight through Tuesday morning.
KEY MESSAGE 1 DESCRIPTION...
Light snow continues across the area this afternoon with
hourly snowfall rates ranging between half inch along I-70 to
as much as an inch across Highland County per recent microwave
passes from NOAA satellites. This snow is expected to exit by
this evening with a second round of heavier precip moving in
around midnight.
The main challenge for tonight is how much temperatures drop
due to evaporative cooling (i.e. in-situ damming) and how much
fzra is able to accumulate. Light winds, marginal temperatures,
and moderate intensity precip rates argue against significant
icing. Continue to favor climatology for ice accretion with
icing remaining west of I-95. After 12Z Tue, strong pressure
falls should help temperatures come up with freezing rain ending
by late morning.
KEY MESSAGE 2...Temperatures warm up by the end of the week and into the
weekend with daily precipitation chances.
KEY MESSAGE 2 DESCRIPTION...
Shortwave troughing tracks over the forecast area Friday with upper
level ridging building over the east coast through the weekend. At
the surface, high pressure shifts off shore as return flow ushers in
moisture and warmer temperatures. High temperatures in the mid 60s
to upper 70s are expected each day with overnight lows in the 50s to
low 60s.
In addition to warmer temperatures, multiple waves of low pressure
track along a stalled frontal boundary across the mid-atlantic. This
yields increased precipitation chances across the northern portions
of the forecast area. With ongoing moderate drought conditions
across the forecast area, rainfall is expected to be beneficial at
this time.
&&
.AVIATION /19Z MONDAY THROUGH SATURDAY/...
Light snow ending by evening with IFR cigs developing. Precip
redevelops tonight with mixed precip expected, then turning to
all rain by midday Tue. IFR conditions persist all day.
South winds blow 5 to 10 knots with gusts up to 15 knots possible on
Thursday. Southwest winds Friday morning shift to southeast in the
afternoon, blowing 5 to 10 knots during the day. Su-VFR conditions
are possible across all terminals due to precipitation chances
except for CHO, where dry conditions are expected.
