Area Forecast Discussion
National Weather Service Wilmington NC
1227 PM EDT Tue Aug 4 2020

.SYNOPSIS...
Isaias has exited the region and impacts from the storm will
continue to diminish this morning. Warm and humid conditions will
provide an elevated chance for afternoon thunderstorms each day
into this weekend.

&&

.UPDATE...
No real changes with the morning update. Maintained the slight
shower chance. Normally there is NVA in the wake of tropical
systems but this one is moving so fast just enough recovery
warrants the continuation.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
Hurricane Isaias continues to move rapidly away from the area
as the center has moved to near Kinston. The rain with Isabel is
quickly moving out, and with the next package from NHC will
remove the Flash Flood Watch. Expect other warnings to be
dropped at the 5 AM NHC forecast package.

A cold front will shift to the coast by Wednesday. This front will
bring a good chance of thunderstorms to the forecast area. Only a
slight chance of thunderstorms is expected this afternoon.

High temperatures today will be in the upper 80s, and on Wednesday,
they will be around 90. Lows Tuesday night will be in the middle 70s
inland to the upper 70s at the coast.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
Deep southwesterly flow will continue as an upper-level trough sits
over the central and eastern portion of the CONUS this week.
Weak shortwave energy will rotate around the apex of the trough
and assist with afternoon thunderstorm development on Thursday.
Temperatures on Wednesday and Thursday night are likely to
remain warmer than normal due to the humid and partly or mostly
cloudy conditions expected.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
On Friday, the upper-level trough will flatten and approach the area
as a weak frontal boundary. Unsettled conditions are likely to
continue with afternoon peak heating. Very little change expected on
Saturday with the frontal boundary morphing into a Piedmont trough.
Upper-level flow begins to flatten on Sunday with weak ridging
attempting to build into the area early next week. Overall, rain
chances will remain above typical afternoon convection chances
through the weekend. Near normal temperatures will begin to increase
toward the end of the weekend and into early next week.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Tropical system moving rapidly northeast and out of the region.
Moderate southwest flow this afternoon with fair weather CU.
Tonight, some fog is expected after midnight, given all the rain in
the past 24 hours. Wednesday, possible convection developing at the
end of the forecast perido.

Extended Outlook...A trough pattern enters the area and brings
typical summertime conditions for the area midweek, including
the chances for afternoon convection and flight restrictions.

&&

.MARINE...
As Isaias moves away from the coastal waters, the offshore wind is
being established. The seas are diminishing, and a small craft
advisory is in effect for waters south of Little River Inlet. Once
the Hurricane Warnings north of Little River Inlet is dropped a
Small Craft Advisory will be issued. Currently, the seas off
Wrightsville Beach are now down to 9 feet, and Frying Pan Shoals
Buoy is down to 14 feet.

Calm winds in a weak gradient field will make for a benign
weather pattern for mariners this week. Seas will generally be
2-3 feet with no significant swell likely. The only notable
threat for boaters will be the elevated thunderstorm chances
each day.

&&

.TIDES/COASTAL FLOODING...
Moderate Flooding is occurring downtown as water levels hit almost 9
feet earlier tonight. The river continues to drop but an incoming
tide will bring the river back above 6 feet so will continue the
coastal flood downtown until noon.

&&

.ILM WATCHES/WARNINGS/ADVISORIES...
SC...None.
NC...High Rip Current Risk until 8 PM EDT this evening for NCZ106-
     108-110.
     Coastal Flood Advisory until noon EDT today for NCZ107.
MARINE...Small Craft Advisory until noon EDT today for AMZ254-256.
     Small Craft Advisory until 2 PM EDT this afternoon for AMZ250-
     252.
