211 FXUS62 KMHX 221421 AFDMHX Area Forecast Discussion National Weather Service Newport/Morehead City NC 1021 AM EDT Tue Apr 22 2025 .SYNOPSIS... Several chances for rain and storms through the rest of the week as a wavy front will be nearby. Total accumulation through the week on the order of one half to just over one inch. A stronger cold front will sweep through late Saturday with better chances for widespread showers and storms. && .NEAR TERM /Through Today/... As of 1020 AM Tue...Main change was to dec pops for today, as main belt of forcing will reside north of the FA this afternoon, towards the VA border. Still kept in a small pop for the nern zones, where convergence of sea and sound breezes may kick off a shower or two with some threat of thunder. The better chance for rain will arrive tonight, when pops inc after around 6pm. Prev disc...As of 0700 Tuesday...A cold front associated with low pressure over Quebec will approach eastern NC late Tue. SWerly flow ahead of the front will advect in low level moisture and combined with surface heating will result in MLCAPE values approaching 1kJ/kg, with SBCAPES a bit higher. This will result in scattered showers and thunderstorms developing inland and north in the afternoon. First, sea/sound/river breeze fronts will be the focus of precip this afternoon. Then, later this afternoon and early evening over the Coastal Plain where the seabreeze will eventually meet the prefrontal trough. It appears that effective shear on order of 25-30 kt will lead to a low end severe weather threat (Marginal- Level 1 of 5) with strong to locally damaging wind gusts and hail the main threats. Best chances for storms will be the northern zones, mainly north of Hwy 264, where 30-50% pops in the forecast late in the afternoon. && .SHORT TERM /Tonight/... As of 0730 Tuesday...Rain to become more likely and more widespread overnight as the front slowly works across the FA. the front will begin crossing inland continues around midnight in conjunction with a shortwave traveling NEward along the 95 corridor with PWATs peaking around 1.5" ahead of the front which will be inching toward the Crystal Coast come sunrise Wednesday. Expecting around half an inch or precip for areas in the Coastal Plain and near the Albemarle. Because of this, have changed from light to moderate showers for precip activity associated with the collision of the seabreeze and prefrontal trough. Continue to carry thunder through the overnight despite the loss of heating, but expecting the strength of storms to be waning through the overnight period. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... As of 255 AM Tuesday...Wednesday through Sunday...The front will move south across the area Wed with scattered to numerous showers and storms with locally heavy rains. There will be enough residual moisture and instability behind the front to keep a chance for isolated to scattered showers and storms across the area Thu and Fri. Yet another cold front is forecast to move through the area late Sat resulting in the threat for more widespread showers and storms. Highs Wed-Fri will be around 80, warming into the 80s Sat. Drier air and cooler temps move in behind the front Sun with just a very low risk for a shower and highs in the 70s. Early next week...Slightly cooler and drier air moves in as high pressure builds over the are from the north early next week. Highs Mon will continue in the 70s. && .AVIATION /14Z TUESDAY THROUGH SATURDAY/... SHORT TERM /through Tue/...

This afternoon there will be a small threat for some sct thunderstorms esp for KPGV/ISO later in the afternoon. Have added precip at the end of this TAF cycle for inland terminals. Flight cats deteriorate after 00Z when cold front and its associated precip begins working across the FA. Keep VIS and CIGs at MVFR for this time with the usual pessimistic guidance showing potential for IFR. LONG TERM /Wednesday through Saturday/... As of 255 AM Tuesday... KEY MESSAGES - TSRA and sub-VFR risk persists for the remainder of the week A wavy frontal boundary will meander over the region through much of the work week.

SHORT TERM /through Tue/... As of 0330 Tuesday...SWerly flow continues with speeds of 10-20 kt. These winds will cont through the day. Afternoon heating gradient will kick up the winds in the sounds to near SCA levels but not long enough duration to warrant a SCA headline. Later Tue afternoon showers and storms will erupt with best chances over Albemarle/Croatan/Roanoke sounds as well as the northern OBX. LONG TERM /Wednesday through Saturday/... As of 255 AM Tuesday... KEY MESSAGES - Veering winds, and increased chances for showers and thunderstorms A cold front will push south through the waters Wed with winds becoming NE around 15 kt and continuing Thu.
