Area Forecast Discussion
National Weather Service Blacksburg VA
159 PM EDT Thu Apr 16 2020

.SYNOPSIS...
A broad upper trough will prevail across the eastern U.S.
through the week. A series of weak disturbances will move
through the trough from the Ohio Valley toward the Mid-Atlantic
region over the next several days. This pattern will bring below
normal temperatures and alternating periods of light
precipitation versus drier periods into the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 900 AM EDT Thursday...

Dry air, some clouds and mixing limited the amount of frost
across the area this morning. Things maybe different tonight as
high pressure settles over the region. We will dive into the
frost/freeze potential for tonight with the afternoon package.

For the rest of today, cold high pressure will approach the
region with breezy/gusty winds into this afternoon.
Temperatures will run about 10F cooler than normal with 40s west
of the Blue Ridge and upper 50s to low 60s east.

As of 311 AM EDT Thursday...

Freeze warning remains in effect for Botetourt and Rockbridge
until 8 AM this morning.

Frost advisories are in effect for Surry,Stokes,Rockingham,Caswell,
Wilkes,Yadkin,Henry,Pittsylvania,Halifax and Charlotte until 8 AM
this morning.

A weak cold front will move southeast across our region this
morning. Some light precipitation may be possible in the
northwest mountains with the front early this morning. Behind
the front, high pressure will build east into our region this
afternoon into tonight. High temperatures will be cooler than
normal with readings from the upper 30s in the northwest
mountains to the lower 60s in the piedmont. The high will slowly
move off the Atlantic coast tonight as a warm front lifts north
across the Ohio Valley. There will be an opportunity to cool
quickly this evening into tonight before winds start to pick up
from the southwest as cloud cover starts to increase with our
next system. However, the timing of models seem slower with the
shortwave. Low temperatures tonight will range from the upper
20s in the mountains to the mid 30s in the piedmont.

Moderate confidence in Near Term Forecast.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/...
As of 100 PM EDT Thursday...

Northern stream disturbance will continue to push east through
the Ohio Valley overnight Friday, with a trailing cold front
extending south into the Tennessee Valley. High pressure builds
in Saturday night and Sunday.

Will begin to see increasing cloud cover, eventually
overspreading the entire area, with rain starting in the far
west in the early morning hours of Saturday. Rain will
transition east, with most areas seeing a steady rain after
sunrise Saturday. This system is quite progressive and much of
the guidance is in agreement of this. Rain and clouds will be
clearing the area by as soon as Saturday evening. Rainfall
amounts are not overly impressive, but with recent rainfall, it
won't take much rain to bring a rise in the creeks and streams.
This will be especially true for the western portions of the
forecast area where 0.50" to 0.75" is possible. East of the
Appalachians, amounts will be much lower, with most areas around
0.25" or less.

The frontal passage with this system will usher in one more
shot of cooler air to the region as high pressure builds in
overhead. With the clear skies and light winds, could see
temperatures fall below freezing Sunday morning. Should quickly
warm up with quite a large diurnal min/max spread with
temperatures reaching into the mid to upper 60s by Sunday
afternoon. However, increasing cloud cover in advance of the
next system may limit temperatures down a bit.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
As of 130 PM EDT Thursday...

Models have been coming into better agreement of a another
system affecting the region on Monday.

Low pressure tracking through the southeast states will likely
overspread the area with widespread rain beginning Monday
morning. Low pressure then tracks east to the Carolina coast by
Monday afternoon, pulling most of the rain out of the forecast
area Monday night. Still a bit of uncertainty how far north this
system tracks and how much rainfall may occur. Still too soon
to talk about any hydro issues.

After the passage of this system, high pressure settles in over
the area through Wednesday and into Thursday as the next storm
system approaches from the west in the latter half of the week.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
As of 605 AM EDT Thursday...

Dry high pressure will keep skies clear into this evening. Some
high clouds may move over the area after midnight as a warm
front lift north into the Ohio Valley.

Breezy northwest with gusts of 20-30 kts this afternoon begin
to decouple after sunset. Winds Thursday will be out of the
south, ranging from 10-15 kts.

Extended Aviation Discussion...

VFR conditions should continue into Friday evening. Sub-VFR
conditions return late Friday night into Saturday morning as a
cold front tracks over the region. High pressure will bring VFR
conditions back to the area Saturday afternoon into Sunday
morning. Restrictions will deteriorate again Sunday afternoon
and continue to remain low into Monday as a wave of low pressure
tracks across the region. Heavy rain and thunderstorms may
accompany this wave on Monday.
