Fxus62 kilm 211345 afdilm area forecast discussion national weather service wilmington nc 945 am edt Thu mar 21 2019 Synopsis Low pressure will move away from the area today with clouds decreasing. After a few showers tonight with the passage of a cold front, dry weather will prevail Friday through the weekend as high pressure builds in from the northwest. Low pressure and a cold front will spread clouds and rain into the carolinas late Monday into Tuesday, followed by high pressure for Wednesday. Near term through Friday As of 945 am Thursday... Low pressure is centered near rocky mount, nc this morning and will continue to lift north and away from our area today. The back edge of the low clouds should reach the pee dee region shortly, although it will take most of the morning for Sun break out in the grand strand, and perhaps until early afternoon for Sun to break out in the CAPE fear region. A few light showers creeping toward bennettsville should largely dissipate as they move east toward dillon and lumberton over the next hour. No significant changes have been made to high temperature forecasts today, still expected to reach the lower to mid 60s for most areas. The warmest portion of our forecast area should be south of florence where the least amount of cloud cover should exist this afternoon, and highs here could make it into the upper 60s. We're also still watching an impressive upper disturbance that will move across the area this evening in tandem with a cold front. Models paint a little better chance of showers with this feature than they did 24 hours ago, and i'll further investigate the potential that gusty winds and or could accompany these showers with very cold air aloft and small low-and-mid level instability present. Discussion from 130 am follows... low pressure is nearing the CAPE fear coast and will continue to lift northward during the day. The bulk of the light to moderate rain will lift northward as well, with the highest pops early this morning mainly across portions of southeast nc. Otherwise a few areas of -dz are expected until some drying occurs later this morning. An energetic shortwave across western tn and northeast ms will lift north of the area by early this afternoon while another shortwave across the midwest results in additional PVA later today and this evening. The secondary feature will also push a cold front through with a shot of uvvs prior to shifting off the coast. Thus after lowering pops later this morning will increase them again to chance levels by later today and this evening. The h5 trough axis will shift off the coast late tonight finally allowing for a drier column. Favor leaning toward the cooler guidance with highs today as a result of cloud cover, and the warmer temperatures tonight with winds expected to remain up with additional clouds. Expect breezy conditions Friday with a blend of high temperatures toward the warmer guidance with cold air advection lagging behind for another period. Otherwise, each high tide could be problematic, especially at the downtown ilm gauge prior to noon today and midnight tonight. Plan on issuing another coastal flood advisory for downtown ilm as a result. Short term Friday night through Saturday night As of 300 am Thursday... Period will be dominated by surface high pressure building in from the northwest as 5h trough moves away from the area. Dry cold front crosses the area Fri night into Sat with cold advection dropping temperatures below climo for sat. Precipitable water drops below 0.20 inch early in the period and remains at or below 0.20 inch into Sun morning. Center of the high moves overhead Sat night with light and variable winds and deep dry air allowing for strong radiational cooling. Low temperatures Sat night will drop into the mid 30s and typical cold spots strong radiational cooling areas have a good shot at dropping to or below freezing. Long term Sunday through Wednesday As of 300 am Thursday... Broad 5h trough sets up early next week as surface high shifts off the coast. Southern stream shortwave emerges from the near the four corners region Sun into sun night, then races east mon. This wave helps develop low pressure, in the southeast, along a cold front trailing a low in

the canadian maritimes. This complex system will likely bring showers to the southeast Mon night which could linger into tue (with potential for isolated thunderstorms - although they will not be included just yet given low confidence). High pressure will build in for the end of the period as the mid-level trough axis moves overhead. -high pressure will keep the region dry Sun and mon, with increasing clouds on mon. Temperatures near climo Sun and above climo on mon. -best rainfall chances will be Mon night and Tue with temperatures above climo Mon night and near climo tue. -drier and cooler air arrives late Tue night and Wed with rainfall ending by daybreak Wed and temperatures dropping below climo. Aviation 12z Thursday through Monday As of 12z... .Current lifr ifr ceilings across the area will slowly dissipate as low pressure system that moved inland in our area overnight moves off to the north. Ceilings will improve at flo next couple of hours, with myr cre soon after, then lbt around 16z, and ilm by 18z. Current ifr MVFR vsbys in our area will slowly improve next couple of hours.VFR conditions to prevail after low cloud deck dissipates. Sct bkn clouds around 5-10 kft this evening with passage of a cold front that might eek out some rain, though with only slight chance forecasted have kept vcsh out of tafs for now. Winds to remain elevated out of the west today around 10 kts with gusts in the teens, mostly at coastal sites. Extended outlook...VFR Friday through early next week. Marine As of 945 am Thursday... Winds and seas are very slowly decreasing across the coastal waters after the storminess of the past 24 hours. Low pressure centered near rocky mount, nc will move north and farther away from the area today. Breezy winds will redevelop tonight as a cold front moves off the coast. The small craft advisory has been allowed to expire for the south carolina coastal waters although conditions remains less than ideal with 4-5 foot seas and west winds up to 15 kt today. Larger seas remain near CAPE fear where the advisory will remain in effect. Discussion from 130 am follows... low pressure is approaching the coast near CAPE fear early this morning. A southeast fetch east of the low has generated seas around 10 ft at the frying pan shoals buoy and even 8 ft at the waverider 5 miles off wrightsville beach. The sc waters have primarily experienced offshore flow on the west side of the low. As the low moves farther inland this morning a westerly flow will prevail. As a result, conditions will drop below small craft thresholds across the sc waters by around daybreak, but seas will remain up for the CAPE fear waters through much of the day. NW to W flow will prevail Friday with speeds 15-20 knots, highest for the offshore waters southeast of CAPE fear. Seas could once again flirt with small craft thresholds for that portion of the coastal waters during Friday. Dry cold front will move across the waters Fri night into Sat with a bump in offshore flow likely. Gradient briefly tightens up and speeds around 20 kt will be possible during the pre-dawn hours. Seas will quickly subside in the offshore flow regime, dropping from 3 to 5 ft Fri night to 2 to 4 ft Sat morning. Surface high spreads over the waters Sat into Sun with northwest winds around 10 kt sat afternoon becoming light and variable Sat night and sun. Seas continue falling Sat dropping under 3 ft around midday and 2 ft or less Sat night and sun. Center of the highs shifts east of the waters Sun night into Mon with light southerly flow gradually increasing to 10 to 15 kt by the end of the period. Seas will slowly build mon, reaching 2 to 3 ft by the end of the period. Ilm watches warnings advisories Sc... None. Nc... Coastal flood advisory until 1 pm edt this afternoon for ncz107. Marine... Small craft advisory until 6 am edt Friday for amz250-252. Synopsis... Srp tra near term... Tra srp short term... Iii long term... Iii aviation... Vao
