AREA FORECAST DISCUSSION National Weather Service Wakefield VA 130 PM EDT Tue Mar 31 2020

SYNOPSIS. Low pressure tracks east across the Gulf coast states today, and then tracks off the Coastal Carolinas while intensifying tonight into Wednesday. High pressure returns to the area Thursday and Friday as low pressure lingers well offshore.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 1015 AM EDT Tuesday .

Current radar imagery showing returns across south central VA and NC, but cloud deck is still around 10 kft and no stations are reporting precip. Dewpoints are in the low to mid 40s, so it will still be a few hours before moisture overcomes low level dry air. POPS increase after 17Z and models differ some on exactly when the precip will start in earnest, but NAM and HRRR increase precip significantly from 18Z-21Z as frontogenetic forcing starts to kick in.

Temperatures will be tricky and have lowered them a couple of degrees especially in the east where onshore flow and some lower clouds are keeping things cooler. Cooled highs for today just a degree or two. The NE flow and cloud cover will keep temperatures in the 50s for most locations, with highs maybe in the upper 50s to near 60F for interior NE NC, and potentially only upper 40s for the MD coast.

The southern stream trough will push ewd across the Tennessee Valley today as surface low pressure becomes more organized across AL/GA by this aftn. Meanwhile, surface high pressure will remain anchored across ON/QB, and this combined with falling pressure to the SW will allow for persistent NE flow today. Clouds thicken and lower by this afternoon. Rain should arrive in the Piedmont by this aftn, and then spread into central/SE VA and NE NC toward late aftn/early evening.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/. As of 355 AM EDT Tuesday .

The upper trough will push across the region tonight, with surface low pressure intensifying along the Carolina coast this evening, and then rapidly deepening off the Outer Banks later tonight/early Wednesday morning. Rain will overspread the entire region this evening (with the exception of the lower MD Ern Shore), with the highest PoPs area-wide from 00-06z, then shifting to mainly SE VA/NE NC later tonight into early Wednesday morning (06-12z). PoPs this evening range from 30-50% for the MD Ern Shore to 100% from central VA through SE VA/NE NC, then remaining near 100% for far SE VA/NE NC later tonight, and tapering to 30-60% elsewhere. Strong vertical ascent with the deepening low will result in periods of moderate to heavy rain for far SE VA/NE NC where QPF is in vicinity of 1.00", with amounts gradually tapering down to 0.25" or less for the far nrn tier of the area. The strengthening low will result in breezy to windy conditions along the coast later tonight into Wednesday morning. A N to NE wind of 25-35 mph with gusts up to 50 mph is expected for Outer Banks Currituck, with 20-30 mph with gusts to around 40 mph elsewhere for coastal SE VA and NE NC along the sounds. Gradually improving conditions area expected Wednesday as the low pulls farther offshore and drier air arrives from the NW. Lows tonight range from the low to mid 40s (upper 30s far NW), followed by highs Wednesday in the mid/upper 50s, with low 50s along the Atlantic coast of the Ern Shore.

High pressure builds in from the NW Wednesday night into Thursday as low pressure lingers offshore. Partly cloudy to mostly clear Wednesday night with lows in the upper 30s to low 40s. Partly to mostly sunny Thursday with highs in the upper 50s to low 60s (mid 50s along the coast).

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 355 AM EDT Tuesday .

Medium range begins with the mid/upper level pattern showing a rather strong upper low lingering well off the NE/mid-Atlantic US coast, as an upper ridge amplifies N into the MS Valley and western Great Lakes. This will keep conditions on the cool side Thu night/Fri with northerly flow in place. The latest 12Z/30 GFS/ECMWF depict some shortwave energy aloft dropping SSE through the local area Fri aftn/Fri night. The airmass is progged to be mainly dry but will keep at least some clouds into the area Fri with highs only 55-60F near the coast and into the 60-65F range W of Chesapeake Bay. Will have ~15% Pops for the eastern 1/2 of the CWA Fri night. Partly to mostly cloudy with lows mainly ranging through the 40s.

The upper ridge to our W is the expected to flatten a bit into the weekend as the next upper trough rides E from the northern Plains Sat aftn/Sat night, and across the northern Great Lakes by late Sunday. Dry with seasonable temperatures Sat (highs upper 50s eastern shore and immediate coast to mid 60s well inland). Lows mostly in the 40s Sat night, then partly cloudy with some increasing moisture by Sun aftn. Highs will trend up a few degrees, upper 60s/near 70F well inland and in the lower-mid 60s closer to the coast. Late in the period, Sun night into Mon is where the models diverge with the ECMWF stronger and farther south with the upper trough as it shifts SE through New England. The GFS (and GEFS mean) keeps the upper trough farther N and also would suggest that a frontal boundary will stall over the region by Mon. WPC/blended solutions generally favor the ECWMF to some extent and given the uncertainty will keep PoPs capped in the 20-30% range with the greatest chance for showers late Sun into Sun night/early Mon (highest PoPs N/NE zones). Highs in the 60s to lower 70s Mon with ~20% PoP remaining for now.

AVIATION /18Z TUESDAY THROUGH SUNDAY/. As of 130 PM EDT Tuesday .

High pressure over eastern Canada is ridging to the south into the mid atlantic while deepening mid level moisture is streaming in from the southwest as low pressure tracks across Georgia. The low pressure system will deepen and approach from the SW this evening and track across the Outer Banks tonight. Rain and degraded flight conditions will develop this aftn and persist through tonight with most sites going IFR for a prolonged period of time overnight. Expect low ceilings as well as moderate rain both resulting in IFR conditions. The NE wind will also increase overnight to 20kt, with gusts to 25-30kt is expected at ORF/ECG by later tonight. SBY looks to be just north of the more moderate rain and as of now forecasting mainly MVFR ceilings there though there could be a brief period of IFR even at SBY overnight.

Conditions slowly improve Wednesday as low pressure pushes offshore, although a strong N wind will persist at ORF/ECG Wednesday morning. High pressure builds in from the NW Wednesday night through Friday as low pressure lingers offshore. High pressure slides across the area Saturday, with a weak front bringing a slight chc of showers Sunday, with high pressure returning Monday.

MARINE. As of 355 AM EDT Tuesday .

A cold front has dropped S of the waters early this morning. N-NE winds briefly gusted to 25-30 kt immediately following the FROPA. However, winds have now diminished to 10-15 kt over the Ches Bay/10- 20 kt over the ocean. Seas are 3-4 ft N/4-5 ft S, with 1-3 ft waves on the Ches Bay (highest at the mouth).

Winds become E at ~10 kt today as weak high pressure builds N of the region. Meanwhile, low pressure currently over the Lower MS River Valley will deepen some as it tracks eastward today, moving just offshore of the Carolina coast by late this evening. The low then turns ENE and is progged to rapidly deepen as it tracks off the NC coast tonight into Wednesday. As a result, ENE-NE winds increase to 22-27 kt over the bay/25-32 kt over the ocean (on average) by early Wed AM. The highest winds will be over the srn bay/coastal waters (closest to the center of the low). Winds turn more to the NNE by late Wed AM as the low tracks offshore before slowly diminishing and turning more to the N by late Wed as the low moves well offshore of the local area and the pressure gradient relaxes some. The latest 00z/31 guidance has trended upward with the strength of the low (and therefore winds across the marine area). Gale Warnings have been issued for the coastal waters S of Parramore Island, the Currituck Sound, and the mouth of the Ches Bay from late this evening through Wed aftn (18-21z). Frequent gusts of 35-40 kt are likely in these areas, with gusts up to 45 kt possible across the NE NC coastal waters. A Wind Advisory has been issued for Eastern Currituck County as well (for gusts up to 45-50 mph). SCAs are in effect starting this evening for the remainder of the Ches Bay, nrn two coastal zones, and all of the rivers starting this evening. SCAs run through 10z Thu (end of 4th period) for the Ches Bay/nrn coastal waters, and end Wed aftn/evening for the rivers. Will likely see a few gusts to 35 kt across the middle/lower Ches Bay and nrn two coastal zones from late tonight-early Wed aftn. Future shifts may need to upgrade these areas to a Gale Warning if models continue to trend upward with respect to winds.

Seas build to 6-9 ft N and 8-13 ft S tonight into Wednesday. Went ahead and issued a High Surf Advisory for VA Beach/Ern Currituck given high confidence in 8 ft+ seas nearshore (from 06z Wed-06z Thu). High pressure slowly builds in from the NW late Wednesday through Friday as the strong low lingers offshore and upper troughing remains over the Mid-Atlantic/Northeast CONUS coast. The wind will be NNW-NW from Wed night-Fri. Nocturnal CAA surges Wed night and Thu night will allow winds to increase to 20-25 kt (sustained) late Wed night and again late Thu night. That is the reasoning behind the extension of the SCAs through the end of the 4th period for the Ches Bay/nrn coastal waters (despite the brief decrease in winds Wed evening). Winds may diminish a bit during the day/evening on Thu, but will likely remain near SCA thresholds over the bay/ocean. Seas will likely remain elevated (aoa SCA thresholds) through at least part of Fri due to swell with the low lingering offshore. Winds finally diminish below SCA thresholds by late Fri- Fri night as high pressure builds over the waters.

TIDES/COASTAL FLOODING. As of 515 AM EDT Tuesday .

Low pressure is forecast to track across and off the NC Outer Banks tonight into Wednesday bringing increasing NE winds tonight, shifting to the NNE-N on Wed. This will result increasing tidal anomalies, particularly during high tide late tonight/Wednesday morning. The latest guidance has trended slightly upward with water levels across the area, and continues to depict the highest departures (2.0-2.5 ft above astronomical) over the lower Bay/lower James during the high tide cycle late tonight- Wed AM. Went ahead and issued a Coastal Flood Advisory for all areas adjacent to the Lower Ches Bay, James River, and Atlantic Ocean (S of Wachapreague). Water levels at Bayford may even touch moderate flood thresholds, while levels at most other locations in the advisory area will see water levels solidly in the minor flood range.

In addition, nuisance-minor flooding is possible across the rest of the area adjacent to the Ches Bay (especially the VA Northern Neck) late tonight-Wed AM. Will hold off on issuing any additional advisories and will let day shift assess the potential. Additional statements/advisories will likely be issued by the end of the day today. Additional (nuisance-minor) coastal flooding is possible during the high tide Wed night-Thu AM in areas adjacent to the Ches Bay (although it is the lower astronomical tide).
