| Area Forecast Discussion National Weather Service Wilmington NC 345pm EDT Fri May 20 2022 Synopsis Unseasonably warm weather will continue with a gradual increase in shower and thunderstorm chances through the weekend. Better rain chances arrive next week as a cold front moves into the area late Monday with a relative cooldown on Tuesday. The front may linger before returning north on Wednesday with warmer temperatures into midweek. Near Term - Through Saturday Ridge will shift eastward through Saturday giving way to temps being a few degrees less on Saturday. Winds will back overall with mid to upper level flow turning from more westerly to a more southerly direction. This will increase moisture through the column with generally an increase in cirrus, but models also showing a minor perturbation riding up from the south around the periphery of the ridge on Sat. Timing is always tough with these features, but should see an increase in mid to high clouds and cu development by Sat afternoon. The question is how much the ridge will hold on, but think the best chance of convection will be across SC, mainly the Pee Dee Sat afternoon. But, kept pops limited to chance for now with mainly iso to scattered pulse type storms with focus along Piedmont trough inland. Convergence along sea breeze should be still under greater influence from ridge with greater subsidence and more limited chance of convection. Temps tonight will remain warm with lows only falling into the 70s. Light southerly winds may drop enough to produce some patchy fog, but not expecting much. The high temps on Sat will fall short of records with most readings around 90 degrees except slightly less hot at the beaches. Short Term - Saturday Night Through Sunday Night Long Term - Monday Through Friday The workweek will begin with a frontal boundary lingering somewhere across the eastern Carolina. The ridge axis offshore will build westward through midweek, nudging the surface front westward as well. Mon-Wednesday should be convectively active days, with the front acting as a focusing mechanism and ample moisture and surface-based instability more typical of July. Thursday may see less areal coverage of showers/tstms, before activity increases again Friday ahead of a strong 500 mb trough. Marine Through Saturday: S-SW return flow will continue through Saturday around high pressure to the east. Healthy sea breeze will develop near shore on Sat afternoon once again as temps soar into the 80s with water temps in the 70s. Seas will be in the 2 to 4 ft range with a continued southerly push and a slightly longer period 8 to 9 second SE swell mixing in. Saturday night through Wednesday... Bermuda High will remain offshore through the weekend and into the start of next week, maintaining southwest flow across the waters. Through Monday speeds will generally be 10 to 15 kt. Stalled frontal boundary will be in the vicinity Monday and Tuesday. Wind direction may end up being quite variable, as it will depend on the exact location of the boundary. Confidence in that is low at this time, but latest guidance is suggesting it will slide just south of the area for a period of time Monday night and Tuesday, resulting in NE flow around 15 kts. Surface high pressure offshore will build westward into midweek, pushing the front inland with SSE flow developing. Also, the period should remain convectively active, with scattered showers and tstms concentrated along the front. NOAA Wilmington NC Office: Watches - Warnings - Advisories SC...None. NC...None.
