AMZ200 1223 Am Edt Sat Apr 27 2024

FXUS62 KILM 270515 AFDILM

Area Forecast Discussion National Weather Service Wilmington NC 115 AM EDT Sat Apr 27 2024

SYNOPSIS
High pressure will build in from the north through Saturday with dry weather expected. A warming trend will develop early next week as the center of the high shifts to off the southeast US coast. A cold front will approach the area late next week, increasing rain chances.

UPDATE
No changes with the 1 AM EDT update.

NEAR TERM /THROUGH TODAY/
Surface high pressure centered over New England will shift slowly eastward through the period while maintaining a ridge of high pressure southward along the East Coast. Aloft, mid-level ridging will shift eastward and bring its axis overhead by the end of the period. This will keep a dry forecast in play with variable cloudiness as areas of enhanced moisture and subtle lift pass through at different levels of the atmosphere. With easterly low- level flow persisting on the south side of the aforementioned surface high, expect temperatures to remain near-normal to slightly cooler than normal for this time of year, with tonight's lows in the mid-upper 50s and Saturday's highs in the mid-upper 70s. A notable warmup awaits from Sunday onward.

SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/
The center of high pressure will shift from our north to off the SC/NC coasts by Sun night, with high pressure aloft through the end of the period. Dry conditions in store with mid/high level clouds overnight Sat clearing out through Sun AM, transitioning to some lower clouds during the aftn due to flow around the shifting high.
Could see a similar situation Mon but with less potent cloud cover, the thicker clouds to our west. Highs near 80 Sun warming into the mid 80s Mon. Lows in the mid to upper 50s.

LONG TERM /TUESDAY THROUGH FRIDAY/
A shortwave trough will push through late Tues into Wed as the surface high is pushed out to sea where it will linger but further offshore. Low shower/storm chances are possible Wed and Thurs due to daytime instability and PWATs 1-1.5". Rain chances will increase towards the end of the period with another shortwave moving through Thurs night and an approaching cold front for Fri. Otherwise, temperatures will be on the rise as 850mb temps hover around 15-17C paired with mostly sunny skies. A shortwave ridge building in Thurs ahead of the trough/cold front will likely make it the warmest day of the period area-wide with highs near 90.

AVIATION /05Z SATURDAY THROUGH WEDNESDAY/
VFR. Mid level cloud cover likely to develop inland and toward the coast later in the day. Onshore flow today gradually veers as high pressure slides southward.

Extended Outlook... Predominately VFR expected through early next week outside of a low chance of morning fog or low cigs each morning.

MARINE
Through Saturday... With high pressure well to the north, ENE flow this afternoon will veer to E tonight and continue through Saturday, with speeds of mainly 10-15 kts with gusts up to around 20 kts. 2-4 ft seas will be primarily driven by easterly wind waves with a period of 5 seconds.

Saturday Night through Wednesday...E winds will become S by Sun then SW later in the say due to offshore high pressure centering off the SC/NC coasts. SW winds will become more S during the afternoons through the end of the period wind speeds 10-15 kts. Seas 3-4 ft will become more 2-3 ft as the high moves further offshore Tues.

ILM WATCHES/WARNINGS/ADVISORIES
NC...None.
SC...None.
MARINE...None.
