cold high pressure Friday into Saturday. The high will move
offshore Sunday with a cold front approaching from the west
Monday. The front will cross Monday night followed by high
pressure Tuesday.


As of 10 AM Thu...No changes needed with morning update. Still a
small threat for an iso sprinkle or shower though moisture very
limited so no more than a trace anticipated.

shows ill defined front moving through the Piedmont region this
morning, with cold 1047mb high pressure centered over southern
Alberta extending into the central US. The front will approach
from the west this morning crossing the region this afternoon.
Latest satellite imagery shows increasing cloud cover ahead of the
front, while radar imagery shows very little precip
upstream...though maybe some sprinkles across central NC. Models
continue to trend drier today, though the high res models do show
potential for very isolated light showers across late this morning
and early afternoon...with best chances across the coastal plain.
Will keep iso shower mention despite the limited moisture and
forcing, with most locations remaining dry. Light S/SW flow head
of the front should allow temps to warm to around 55-60 degrees.
Winds become NW and gusty after the frontal passage this afternoon
with temps falling as CAA ramps up.
