Area Forecast Discussion National Weather Service Wilmington NC 235 AM EDT Mon Jun 21 2021

SYNOPSIS. Claudette will bring heavy rain and isolated tornados overnight into Monday morning. After a one day break Monday another round of heavy rain returns Tuesday. Cooler air will move in on Wednesday with just a slow recovery Tuesday. The latter part of the week and weekend look seasonable with the normal June scattering of thunderstorms.

UPDATE. What could be the final organized line of convection (although in reality there have been only a couple) according to some high resolution guidance is currently moving southwest to northeast across the area. Will wait until a bit later to make wholesale changes to pops, FFA (may remove early) and perhaps other fields.

NEAR TERM /THROUGH TUESDAY/. The first 12 to 18 hours of the forecast will be dominated by the effects of Claudette with showers and wind through about daybreak Monday. In the wake of the TC, expect isolated showers and storms Monday and Monday night due to minimal forcing and slightly drier air over the area. Moisture will return Monday night on SW flow ahead of an advancing cold with the possibility of a shower or storm toward daybreak Tuesday.

SHORT TERM /TUESDAY NIGHT/. PW values surge as high as 2.2" Tuesday ahead of a surface cold front and upper trough. Not surprising then to see some strong convective signals in model guidance indicating the chance for some heavy rainfall. SPC is also highlighting the area for a Marginal Risk in their Day 3 Convective Outlook. There are some timing differences that will affect the available instability. Even with meager instability some wet microbursts should be possible given the copious deep layer moisture.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. A wedge of high pressure builds in from the north Wednesday; some places struggling to hit 80 as they sky remains overcast. Partial sunshine returns Thursday as the ridge weakens. Both days represent a challenging rainfall forecast as moisture appears to be shunted off the coast but many models are still showing POPs both days . as a result have lowered forecast values. Friday also not quite as depicted by model guidance as a weak warm front moves through but with little support for ascent aloft. Thunderstorms will likely have fairly normal coverage for the season over the weekend as a few shortwaves traverse the area while Atlantic high pressure continues to supply moisture.

AVIATION /06Z MONDAY THROUGH FRIDAY/. MVFR/IFR conditions to start this 24 hr period. As tropical cyclone Claudette exits NE of the area by sunrise and to off the Outer Banbs by midday. Look for improving conditions to dominant VFR by mid to late this morning. Low and mid level clouds should clear out by mid-morning leaving just high level moisture and subsidence across the FA thru 06Z Tue. Winds generally will run WSW-SW 10-15 kt this morning and 10-20 kt with gusts to 25+ kt this aftn.

Extended Outlook . Convection with periodic MVFR/IFR, late Tue Night will slide just off the Carolina Coasts come early Wed. MVFR/IFR ceilings are possible Wed after the CFP but should improve and clear out inland. Mainly VFR Thu thru Fri.

MARINE. Through Monday night . expect frisky conditions through the period with tropical storm conditions expected tonight into Monday before and approaching cold front ramps SW flow back up to about SCA levels by Monday evening. Seas are expected to build tonight to about 5 to 8 FT by midnight then fall slightly during Monday, though 4 to 6 footers could continue into Monday night.

Tuesday through Friday . Southwesterly prefrontal winds Tuesday and Tuesday night may be sufficient to keep advisory-worthy 6 ft seas in the area. An abrupt veer with FROPA is slated for Wednesday morning so even as predominant wave heights fall below criteria there will be a transition to a shorter period, steeper sea state. Uncommon NE winds Wednesday night as high pressure wedges in from the north, followed by a gradual weakening trend on Thursday. Southerly component returns by Friday and with speeds that will allow predominant wave heights to continue to abate. Spectral plots are showing a very long period 1 ft swell as early as Wednesday but given its small stature will likely be more of a beach hazard than a boating hazard.
