High pressure will build south of the region tonight and Monday.
Two dry cold fronts will pass through this week, the first one
Tuesday, the second one Thursday night.


As of 945 PM Sunday...Clear skies and light to calm winds
continue across the region as strong high pressure continues to
build east from the western Gulf Coast. Excellent radiational
cooling conditions expected overnight and have lowered
temperatures in the normally colder locations another degree or
two overnight. Lowest readings in the mid/upper 20s inland with
low/mid 30s Outer Banks.


As of 245 PM Sunday...High pressure will weaken to the south as
diving low moves through the Mid-West, and flow becomes zonal
across the area. Low level thickness values and sunny skies
support highs in the low/mid 50s.


As of 200 am Sun...Temps moderate a bit Mon into Tue as
thicknesses increase a bit ahead of next short wave/cold front.
Continue mostly sunny Mon then will see a few more clouds Tue
ahead of shortwave but moisture is very limited so not expecting
precip. Highs mostly low to mid 50s Mon and Tue. Lows Mon night
mid 30s inland to 40s cst.

Another shot of arctic air will surge in Tue night and Wed as
upper trof crosses the region. Models now mainly dry with

bit more zonal. Dry weather will continue with highs Thu mid
40s to low 50s and mostly low/mid 50s for Fri and Sat.


Short Term /through 00Z Tuesday/...
As of 645 PM Sunday...Under the influence of strong high

fog from developing tonight.
