Friday night through Sunday... Sfc high will build into the
region from the northwest Friday night through Sunday. While to
the west, an mid/upper level low will move across the Southern
Plains/Lower MS Valley, while at the sfc an area of low pressure
develops over the Gulf States. Expect mostly sunny with cool
temperatures through Saturday, then Sunday an increase of clouds
ahead of the low pressure system. Expect highs in the 60s with
temperatures increasing 3-4 degree each day. Friday night will
be a chilly night for this time of year, expect overnight lows
around 40 degrees inland to mid/upper 40s along the Outer Banks.
Saturday night, expect lows in the low/mid 40s inland and
mid/upper 40s coast, then Sunday night, lows in the mid/upper
40s inland to low/mid 50s coast.

Monday through Wednesday... The 00z models have a general consensus
with the sfc low developing over the Gulf States and lifting towards
the Carolinas Tues/Wed., but aloft the models don`t have a good
handle with the upper level cut-off low. Therefore, uncertainty
remains with the timing of the sfc low and strength/track of cut-off
low aloft. With the models in agreement with timing of the precip,
have decreased PoPs slightly Monday, but kept 30-50% PoPs Tues/Wed.
The warming trends continues through Wednesday with highs in the
upper 60s/low 70s inland and low/mid 60s Outer Banks.
