AREA FORECAST DISCUSSION National Weather Service Wakefield VA 953 PM EDT Sun Jul 5 2020

SYNOPSIS. Weak high pressure will remain centered along the mid Atlantic coast through Monday, before moving farther offshore on Tuesday. Low pressure moves from the deep south to the Carolina coast on Wednesday, and lingers along the coast through Friday.

NEAR TERM /THROUGH MONDAY/. As of 955 PM EDT Sunday .

Convection is waning across the Piedmont this evening. Otherwise, partly cloudy to mostly clear with temperatures in the upper 70s to low 80s. Dewpoints this evening are actually highest from central VA through the Piedmont where values are in the low mid 70s, while locations closer to the coast and over s-central VA and interior NE NC are in the upper 60s to around 70F. Lows tonight range from 70-75F, with some upper 60s over interior srn VA/NE NC. Patchy fog is possible over the NW Piedmont, especially for areas that received rain earlier this evening.

Heights aloft rise slightly on Mon as do H8 temps. Not expecting any AM convection as the flow becomes S to SSW. Highs will range from the mid 90s in the interior with upper 80s to lower 90s on the coast. Best chance for convection looks to be across the N during the late aftn/evening (~40%) with only about 20% for the southern 1/2 of the CWA. SPC has a marginal risk across the N where somewhat steeper mid level lapse rates and shear could lead to isolated strong/severe storms.

SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/. As of 330 PM EDT Sunday .

Chance PoPs linger Mon evening across the N, otherwise drying overnight with lows mainly 70-75F. By Tue, developing low pressure across the deep south will slowly move NE closer to the local area, but latest 12Z/05 GFS/NAM/ECMWF generally remain in good agreement that the deeper moisture will stay S of the local area. Thus, PoPs will again be mainly diurnal with just scattered 30-40% coverage from the mid/late aftn into the evening (PoPs staying only around 20% near the coast). Highs will be slightly cooler compared to Mon, primarily in the upper 80s at the immediate coast and over most of NE NC, with lower 90s elsewhere. From Tue night into early Wed, the low moves E across the Carolinas and then is expected to linger along the Carolina coast by Wed aftn with weak steering flow aloft. Have at least some PoPs across the southern zones all night Tue night, spreading N on Wed. It will be humid with dew pts into the lower to mid 70s and highs will be slightly cooler (especially in the S) due to more clouds, ranging from the mid 80s S to around 90F N.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 400 PM EDT Friday .

05/12z global models and associated ensemble suites continue to depict an upper low and broad surface low pressure in vicinity of the Carolina and Mid-Atlantic coasts Wednesday night into Thursday. At this time, the general consensus is for this system to lift NE Thursday night into Friday as a strengthening upper level trough drops into the Ohio Valley Saturday into Sunday. Forecast PoPs Thursday range from 20-30% N to 40-50% S, and then 40- 50% across most of the area Friday and Saturday, and trending back toward a 20-30% climo PoP by Sunday. Forecast highs are generally in the mid/upper 80s Thursday, and then upper 80s to low 90s (mid 80s at the immediate coast) Friday through Sunday and these values are very typical for early July. Forecast lows are mainly in the upper 60s to low 70s.

AVIATION /02Z MONDAY THROUGH FRIDAY/. As of 800 PM EDT Sunday .

VFR under SCT high clouds this evening. A few showers/tstms over the Piedmont are expected to dissipate later this evening and remain W of RIC. Patchy fog is possible after 06z, but is expected to remain over the Piedmont and not affect any of the terminals. Otherwise, a light SE will become SW overnight. Mostly sunny Monday morning with SCT CU developing during the aftn. There is a 30% chc of aftn showers/tstms at RIC, and 20% at SBY/PHF. The wind is expected to be southerly at 8-10kt from late morning through the aftn.

Any lingering showers/tstms should dissipate Monday evening, with VFR conditions prevailing Monday night into Tuesday, and a 20-30% chc of aftn showers/tstms Tuesday. At this time, there is a somewhat increased chc of showers/tstms from Wednesday aftn through Friday as low pressure is forecast to become located in vicinity of the Carolinas.

MARINE. As of 330 PM EDT Sunday .

5-10 kt winds across the waters this afternoon, southerly from Cape Charles northward and southeasterly from the mouth of the Ches bay south. Waves are around 1 ft with 2 ft near the mouth of the bay while seas offshore are 2-3 ft.

SSE winds increase to 10-15 kt (highest generally from Cape Henry N) this evening then become S and SSW later tonight. Much of the same is expected for Monday and Tuesday with 5-10 kt SSE flow becoming S and SSW 10-15 in the late afternoon into the evening. Waves generally 1-2 ft and seas 2-3 ft. The picture become a bit murky for the mid/late week period with global models generally agreeing on a trough or closed low aloft over the Mid Atlantic/SE and a modest surface low near the Carolina coast on Wednesday. Thereafter, solutions diverge considerably with respect to the track and timing of the surface low through the region. Went with a blended approach showing increasing onshore flow and seas starting Wednesday night into early Friday from south to north.

TIDES/COASTAL FLOODING. As of 400 PM EDT Sunday .

Modestly increasing south and southeasterly winds this evening will combine with high astronomical tides tonight into early Monday, resulting in the potential for minor coastal flooding for the bay facing portions of the lower MD eastern shore. Nuisance flooding is also possible along the Northern Neck/Potomac river counties as well as VA portions of the eastern shore this evening and tonight. Additional flooding is possible during the high tide cycle Monday night with continued southerly flow.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
