AREA FORECAST DISCUSSION National Weather Service Wakefield VA 244 PM EDT Mon Apr 19 2021

SYNOPSIS. An upper level trough crosses the area this evening which will kick a weak low pressure off the Carolina coast out to sea. High pressure builds over the region tonight through Tuesday evening. A cold front crosses the region on Wednesday bringing another chance for showers and thunderstorms. Cool high pressure builds across the region Wednesday night through Friday.

NEAR TERM /THROUGH TONIGHT/. As of 230 PM EDT Monday .

Latest analysis shows weak low pressure off the NC coast and a shortwave just west of the forecast area. Showers and thunderstorms continue this afternoon with the thunder mainly confined to the S/SE where there is more instability. Plenty of pea size hail reports this morning into early afternoon, and expect that larger hail will be possible in cells that form later this afternoon over SE VA and NE NC where temps made it into the upper 60s to lower 70s. Some of the cells may also produce damaging wind gusts. SPC maintains a marginal risk for severe wx across far SE VA and most of NE NC.

Shortwave moves through the area later this afternoon into this evening and will kick the weak low out to sea, bringing an end to the precip by around 00Z tonight. Clearing skies expected late tonight into early Tuesday morning. Patchy fog is expected early Tuesday morning, especially along and east of I-95. Low temps tonight in the low to mid 40s.

SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/. As of 230 PM EDT Monday .

High pressure builds in for Tuesday and will slide off the coast during the late morning into the afternoon. This will result in a warm southerly flow across the region. Partly cloudy conditions expected with afternoon high temps in the low to mid 70s. It will be breezy Tuesday afternoon with wind gusts of 15-25 mph. Milder low temps Tuesday night with the continued southerly flow, only dropping into the low to mid 50s.

A potent upper level trough to our west will cross the area on Wednesday. A surface low pressure will ride up west of the Appalachians into the northeast by Wednesday afternoon into the evening. A cold front associated with the low will cross the area from west to east during the day clearing the coast by Wednesday evening. Scattered showers and thunderstorms are expected along and ahead of the cold front. The best dynamics will be across the N/NE part of the forecast area, which may result in some of the storms being on the stronger side. SPC has much of the region in a marginal risk for severe wx, except for the southern piedmont and NE NC. The SW flow ahead of the front will be breezy Wednesday morning into the afternoon with gusts of 25-30 mph expected. Breezy conditions will continue near the coast overnight with the NW flow after the front passes. High temps Wednesday afternoon will range from the upper 60s out west to mid and upper 70s SE.

Rain comes to an end Wednesday evening as the front moves off the coast and strong high pressure builds in from the west. Temps will plummet overnight into early Thursday morning. Frost/Freeze headlines are possible over inland portions of the area with low temps in the lower 30s expected. It will remain cool and dry during the day on Thursday with high temps only making it up to the upper 50s to lower 60s.

LONG TERM /FRIDAY THROUGH SUNDAY/. As of 230 PM EDT Monday .

One more cold morning expected on Friday with high pressure over the SE states. Low temps will be in the mid to upper 30s for most, and lower 40s near the coast. Plenty of sunshine on Friday with mostly clear skies expected. Afternoon high temps in the mid to upper 60s. Low pressure originating in the four corners region will advance to the deep south by late Friday and then up to the Mid-Atlantic by late Saturday into early Sunday. Showers and thunderstorms are expected, with the highest chances during the second half of Saturday into early Sunday morning. High pressure and drier conditions expected for the second half of Sunday into early next week. High temps Saturday through Monday in the upper 60s to lower 70s. Low temps in the 40s except for Saturday night where milder conditions are expected and lows only fall into the 50s.

AVIATION /19Z MONDAY THROUGH SATURDAY/. As of 100 PM EDT Monday .

Scattered showers and thunderstorms will impact the area this afternoon into early evening, resulting in brief periods of MVFR/IFR ceilings and visbys. Precip moves out off the coast by around 00Z with clearing skies and VFR expected late tonight. Some patchy fog is expected early Tuesday morning which may impact some of the terminals but for this issuance left any mention of fog out. Northerly winds 5-15 kts becoming light and variable overnight. Winds then become southerly late in the period as high pressure moves offshore.

OUTLOOK . Mainly dry through Wednesday morning with high pressure returning. Some flight restrictions will be possible as a front moves into the region later Wednesday and Wednesday night.

MARINE. As of 230 PM EDT Monday .

Latest analysis reveals sfc low (~1005mb) offshore of eastern NC this aftn, with weak high pressure rebuilding well inland of the waters. Resultant winds are out of the NNW and have surged with compressed pressure gradient to high-end SCA over the lower James, Lower Ches Bay, Sound, and southern coastal zones . with some localized higher gusts that have prompted some MWS/SMW this afternoon. SCA flags remain in place for these locations through late this evening. Still appears that seas/waves build only to ~3- 4ft/2-3ft given that the period of stronger wind is relatively short.

High pressure builds over the waters late tonight, before sliding offshore Tuesday and Wednesday. This should allow for winds to diminish quickly this evening, then veering around to the S 10-15kt later Tuesday afternoon into Tuesday night, as the high moves offshore. The wind may briefly reach SCA criteria 15-20kt in the lower Bay and lower james late Tuesday afternoon into Tuesday evening, but will hold off w/any additional headlines with SCA flags already in place at present.

Thereafter, biggest marine impact for the period will be with a strong cold front that approaches from the W Wednesday. The front still on track to quickly move across the area later Wednesday afternoon. SCA conditions are likely in the wake of this cold front Wednesday night with a NW wind of 20-25kt with gusts to ~30kt. In- House Wind Probs highlight a rather brief period (< 3 hrs) of Gale Force gusts to ~35kt possible for the open ocean zones N of Cape Charles and over the middle Bay N of New Point Comfort. Seas build to 5-6ft, with 3-4ft waves in the Bay. High pressure builds across the Southeast Thursday and Friday as low pressure lingers well NE of the region, with seas slowly subsiding into the upcoming weekend.
