Synopsis for fenwick island de to currituck beach light nc out 20 nautical miles including virginia portion of the chesapeake bay, currituck sound and portions of the james, york, and rappahannock rivers -
a secondary surge of cold advection drops south early this morning. Rain chances increases today into this evening, as low pressure tracks along a stalled frontal boundary over the coastal carolinas. Transient high pressure builds over the region by midweek, with a mainly weak, dry cold front pushing across the area late Wednesday into Thursday.

AREA FORECAST DISCUSSION National Weather Service Wakefield VA 421 AM EDT Sun Apr 21 2024

SYNOPSIS
Low pressure will track east northeast off the southeast coast and out to sea today into Monday morning. High pressure will build over the area for later Monday through Tuesday morning, then slides off the coast by Tuesday evening. A cold front will swing across the region on Wednesday.

NEAR TERM /THROUGH TONIGHT/
As of 410 AM EDT Sunday...

Early this morning, sfc low pressure was located along the SE coast. The latest radar showed sctd light radar echoes (very light sprinkles) moving ENE into Ncntrl/NE NC. Otherwise, the sky was partly cloudy to cloudy across the region with temps ranging through the 50s to near 60.

The low pressure system will track ENE and well out to sea today through tonight. Rain will quickly spread into and across just about all the CWA between 12z-18z, with the highest PoPs and best QPF expected over NE NC and SE VA. Have shifted the rain chances farther north into the CWA for this morning through this aftn, with Farmville-Richmond-Wallops Island line likely to receive .05-.10 inch of QPF from this system. Farther SE through NE NC will receive the higher QPF amounts, ranging from 0.20-.75 inch from NW to SE into NE NC for the entire event.

With dew pts quite low as the rain initiates (in the 30s N to the upper 40s S), this will make for a very chilly day where the rain becomes widespread, as a result of column cooling processes. PoPs will range from 60-90% over the S/SE, to 20-30% across the extrm nrn counties. As noted above, temps will be quite cool today, with highs from south central/SE VA and NE NC to avg in the lower to mid 50s, with mid to upper 50s to the N.

Rain will end from NW to SE from later this aftn into tonight, as the low moves farther out to sea. This will be followed by some clearing overnight into Mon morning. With dry air in the low levels overnight (dew pts falling into the lower 30s NW), expect lows to reach down into the mid 30s over the Piedmont, potentially close to freezing in the far NW in the coldest spots. Did not add patchy frost wording to the grids, but this may need to be addressed by the next shift.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
As of 410 AM EDT Sunday...

The models depict ~1025mb sfc high pressure centered from the Lower MS Valley to the lower OH Valley on Mon, ridging E into the local area. Aloft, a weak trough will be in place, but the sky should be sunny or mostly sunny across the local area (with a bit more cloud cover across the far SE). Highs on Mon will be warmer than today, but still 5-10F below avg for late April, ranging from the lower 60s near the coast, to the mid to upper 60s well inland. With low dew pts continuing and sfc high pressure becoming centered over the local area Mon night, expect a clear sky, light winds, and good radiational cooling conditions. Forecast lows are in the mid to upper 30s over much of the CWA, with lower to mid 40s near the coast. At least patchy frost will be possible over much of the CWA Turning warmer on the backside of the sfc high for Tue, with a light southerly flow by aftn. Mainly sunny with highs in the lower 70s inland, and in the mid to upper 60s at the coast. Increasing clouds Tue night in advance of another cold front. Lows in the upper 40s to lower 50s.

LONG TERM /WEDNESDAY THROUGH SATURDAY/
As of 415 AM EDT Sunday...

The system on Wed will be northern stream, with low level flow turning westerly rather quickly. As such, moisture will be limited, and PoPs will only be 20-25% N and 15% or less over the S. Highs will be in the low-mid 70s. Another fairly strong high pressure system is progged to build in from the Great Lakes Thu-Fri. The 12Z/20 GFS is the strongest and therefore the coldest with low temperatures both Wed night/thu AM and again thu night/Fri AM. For now have split the difference going slightly cooler than the NBM for lows, with the potential for some additional frost, especially across the piedmont and over the northern 1/2 of the CWA The high will slide off to the NE or E during Fri. Highs will be in low-mid 60s NE to near 70F SW Thu, and in the upper 60s to lower 70s Fri. There will be at least a low chc for rain by Sat as the next system lifts ENE through the Great Lakes/upper midwest (with quite a bit of model spread at this time). PoPs are only 20-30% for now w/ highs Sat mainly in the 70s.

AVIATION /08Z SUNDAY THROUGH THURSDAY/
As of 230 AM EDT Sunday...

Mainly VFR CIGs (isolated MVFR CIGs ) will prevail at the TAF sites through at least 12-13z this morning, with winds becoming N or NE and increasing at bit. Rain chances increase quickly between 12z-15z this morning across southern VA and NE NC, becoming widespread by late this morning through this aftn at ECG/ORF, and likely PHF as well. There is a chance (30-50%)
for rain at RIC, and a slightly lower chance (20-30%) for rain at SBY. Expect flight restrictions to MVFR initially with a period of IFR CIGs likely at ECG/ORF/PHF from late this morning into this evening. RIC/SBY will mostly be VFR (maybe briefly MVFR) even if there is some light rain. Conditions will improve to VFR from NW to SE this evening into late tonight, as the rain and low pressure area push well ESE of the region.

Outlook: VFR conditions will prevail Mon-Tue, and probably for most of Wed as well.

MARINE
As of 350 AM EDT Sunday...

Early morning analysis shows sfc cold front now stalled offshore of the coastal Carolinas, extending SW across the gulf coast. WV satellite imagery showing developing sfc low pressure developing offshore of Cape Fear, with this system expected to slowly lift NE along the NC coast today into this evening. Meanwhile, 1018+mb sfc high pressure continues to build to our W/NW early this morning. Aloft, flow is largely zonal early this morning, though a shortwave currently over the northern plains will carve out an east coast trough over the eastern third of the country later today through Monday night.

Tightening pressure gradient between developing low pressure to the south and high pressure to the west is resulting in a decent surge of cool air advection early this morning. Latest Obs showing NNW winds ~15-20 kt with gusts 25 kt over the upper and middle bay and northern coastal waters, with lighter winds S of York River light at 07z. Expect this trend will continue across the remainder of the waters over the next few hours, with winds becoming NNE and increasing to 15-20 kt winds over the lower bay/lower James through around 12-14z (8-10 AM) before winds start to slowly diminish late this morning and this afternoon. Winds have also become NNE over coastal waters, which should allow seas to build to 4-5 ft near and south of the VA/NC border, closer to the developing low skirting the region to the SE. SCA flags remain in place for the bay and lower James through this morning, and for the sound and ANZ658 south of the NC border into this afternoon and this evening, respectively.
Will need to monitor trends of High-res CAMs over the next couple of hours, as latest trends continue to point toward potentially needing to maintain SCA into this afternoon over the mouth of the bay and sound.

Previously referenced low pressure moves off the Carolinas slides offshore of the NC coast this evening, with the front lingering offshore into midweek. This supports a persistent NE flow and building seas. Would not be surprised to eventually need another SCA over southern coastal waters south of the VA/NC border Monday afternoon and night, but with an SCA already in place, will keep seas ~ 4 ft for now. Conditions improve later Tue through midweek, as the low and frontal zone edge farther offshore and high pressure builds over the region ahead of another weaker frontal passage by mid-late week.
