Area Forecast Discussion
National Weather Service Wilmington NC
247 AM EST Tue Jan 19 2021

.SYNOPSIS...
Seasonable temperatures, dry and occasionally breezy conditions
will continue into mid week as a series of cold fronts cross
the coast. A warming trend will follow as high pressure over
the Southeast states moves offshore. Rain chances increase late
this week as a weak frontal boundary sets up over the area.
Cooler and drier weather is expected for next weekend.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
Surface high pressure centered across south Georgia has a
northward- extending ridge axis that will push across the
eastern Carolinas this morning. Light and variable winds will
become solidly southwest behind the departing ridge axis this
afternoon. Skies should remain clear and model blends and MOS
products are tightly clustered with forecast highs in the upper
50s for most areas. The beaches from North Myrtle Beach through
Cape Fear should run several degrees cooler as this afternoon's
southwest flow will be moving onshore across water temps only in
the lower 50s.

Winds of 25-30 knots just above the surface will develop
tonight ahead of a dry cold front. While surface winds should
remain less than 10 mph, these winds aloft plus some late night
cloud cover should maintain a turbulent boundary layer. My
forecast lows are a couple degrees above MOS consensus with low-
mid 40s most areas. The thickest cloud cover appears to move
across South Carolina between 2- 5 AM Wednesday morning when
models show saturated conditions between 5-10kft aloft. GFS and
NAM isentropic analysis along the 295K theta surface within the
cloud layer shows neutral to slight downglide occurring during
that time, so I'll maintain a dry forecast. Sunshine and breezy
northwest winds should return on Wednesday with highs 54-59
expected.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
Weak surface high will shift southward over Florida on
Wednesday night. Morning lows should occur just before the
arrival of mid and high level clouds, dropping into the mid 30s
on Thursday morning. Cloud cover and subsequent rain chances
continue to increase throughout the day as moisture spreads
eastward over the area. A nearly stationary front sinks
southward on Thursday night, bringing the best chance of rain,
especially in our southern areas.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
Front continues to move southward on Friday morning as rain
chances decrease throughout the morning into the early
afternoon. The timing of this front's progression through the
area will influence afternoon temperatures and how late in the
day showers remain possible. In general, expect the front to be
well south of the area by Friday night with rain chances coming
to an end. High pressure builds into the area Saturday and
Sunday as cooler and drier conditions develop with temperatures
slightly below climo both days. High pressure moves offshore and
weakens slightly late Monday. Models don't have a good picture
of a low pressure system developing over the Lower Mississippi
River Valley early next week, but portions of the area could see
rain chances return as a warm front lifts north of the area
through Tuesday.

&&

.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
VFR conditions are expected for the next 24 hours.

Extended Outlook...MVFR conditions are expected along with a
low probability of IFR conditions late Thursday night into
Friday as a wave of low pressure brings rain to the area.

&&

.MARINE...
Through Wednesday... High pressure centered over south Georgia
has a ridge axis extending to the north that will sweep across
the Carolina coastal waters late this morning. Our northwest
winds will diminish significantly as the ridge axis approaches,
then will back to the southwest this afternoon. Wind speeds
should increase tonight as a dry cold front approaches from the
west. This boundary should move offshore around daybreak
Wednesday, accompanied by a period of 15-25 knot winds. A Small
Craft Advisory will be issued for the North Carolina waters
where the strongest winds should exist. Slowly diminishing
northwest winds are then expected during the day Wednesday.

Buoys and models continue to show no significant swell
affecting our portion of the Atlantic. Our waves over the next
36 hours should be exclusively wind chop with periods shorter
than 6 seconds.

Wednesday Night through Saturday... Offshore winds continue to
diminish overnight Wednesday and seas become 1-2 feet. Winds
become SW and increase to 15-20 knots with gusts to around 25
knots on Thursday ahead of the next cold front. This could bring
another brief period of SCA conditions into Friday. A west to
east boundary across the area late Thursday will drop southward
on Friday and Friday night. NW winds around 10-15 knots late
Friday become northerly on Friday night, seas 2-4 feet. High
pressure builds into the area on Saturday as northerly winds
increase in strength to near 15-20 knots. Winds decrease
slightly throughout the day to 10-15 knots late Saturday.
