.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 200 PM EDT Friday...
Key Messages: The tranquil weather pattern is set to continue
through the weekend, but a shift in the high pressure will bring
subtle changes to the atmosphere.
A surface high pressure system, which provided dry and sunny
conditions, will slide off the Mid-Atlantic coast on Sunday. This
will mark the beginning of its retreat, but its lingering influence
will keep the entire region dry with fair skies. Overnight low
temperatures will be cool, falling into the mid to upper 40s in the
mountains and the low 50s in the foothills and Piedmont. Afternoon
highs will be comfortable, settling into the 70s.
By Monday, the high pressure will be further away, positioned well
offshore and losing its influence. As a result, the wind pattern
will shift, becoming southerly. This change in wind direction will
slowly transport more moisture into the atmosphere, which will be
noticeable through an increase in cloudiness. Despite the clouds,
the region will remain dry. Low temperatures will still be cool but
may be a degree or two warmer due to the cloud cover, and afternoon
highs will once again be in the 70s.
&&
.LONG TERM /TUESDAY THROUGH THURSDAY/...
As of 200 PM EDT Friday...
Key Message: The week ahead promises a return to more unsettled
weather followed by a noticeable cooling trend.
On Tuesday, a cold front will begin its slow approach toward the
region. This approaching system will increase atmospheric moisture
and instability just enough to generate light showers, which are
possible in the afternoon and early evening hours. High temperatures
for the day will remain mild, settling in the 70s.
Wednesday will see the cold front slowly track across the area.
However, the frontal system will be encountering a pocket of
lingering dry air, which will serve to limit the amount of
precipitation it can produce. As a result, rainfall will be light,
generally ranging from a quarter to a half an inch. High
temperatures will remain in the 70s ahead of the main cold air push.
The front`s forward momentum is then expected to stall. On Thursday,
the frontal boundary will sit over the Carolinas, but it will leave
behind a shield of mid to high clouds draped across Southwest
Virginia, Northwest North Carolina, and Southeast West Virginia. The
cooler air will begin to settle in, with highs expected to drop.
A definitive change to clear, cooler weather arrives on Friday as a
dry high pressure builds in from the north. This high will be strong
enough to push the stalled front further to the south, complSo long as the high pressure influences our airspace, a repeated
pattern of mostly clear skies and overnight fog is possible for
the next few days. The extent of fog may be limited depending
on how dry conditions get. etely clearing out the clouds and
ushering in crisp, dry conditions. This cooldown will be
significant, with high temperatures on both Friday and Saturday
expected to be notably cooler, settling into the 60s.
