AREA FORECAST DISCUSSION National Weather Service Wakefield VA 951 PM EDT Fri Jul 3 2020

SYNOPSIS. High pressure continues to build into the region from the northwest. A weak back door cold front will cross the area on Saturday before dissipating south of the area late in the weekend.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. As of 950 PM EDT Friday .

Mostly clear skies expected to continue overnight although few to scattered clouds will build in the piedmont overnight before clearing around sunrise. A backdoor cold front will approach the region from the N/NE tonight as high pressure over the Midwest noses in behind a weak shortwave aloft. Will maintain very slight chance PoPs for an isolated shower for the lower MD eastern shore. This region could see some clouds linger near the coast overnight before increasing in coverage by the morning. Calm winds and mostly clear skies will allow low temps tonight to fall into the upper 60s to low 70s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY NIGHT/. As of 350 PM EDT Friday .

Aforementioned front is forecast to drop S and SW Saturday morning with winds becoming northerly behind the boundary. Hi-res guidance continues to show the potential for showers and a few storms Saturday afternoon near the I-95 corridor through peak heating in the afternoon. Weak lapse rates aloft and 25 knots or less of shear should keep any storms that form from becoming too strong, however, briefly heavy rain, frequent lightning, and gusty winds are possible in the stronger cores that manage to form. PoPs generally in the 30-40% range Saturday afternoon. High temps low to mid 90s inland with mid to upper 80s for the eastern shore and immediate coast. PoPs decrease quickly after sunset with only a slight chance for lingering showers over the south and southwest, ending before midnight. Otherwise, dry with lows in the upper 60s and low 70s.

Heights increase aloft on Sunday as expansive ridging over the central CONUS moves eastward. Low pressure begins to develop over the north central Gulf Coast on Sunday. Perhaps a few degrees cooler locally on Sunday with highs upper 80s and low 90s. Relative greatest chance for any showers/storms will exist over the southwestern half of the area Sunday afternoon. Lows Sunday night in the mid to upper 60s and low 70s. More of the same is in store for Monday with a chance for scattered showers and storms inland and lesser chances near the coast as low pressure over the Gulf states begins to move toward the region. Warm again Monday with highs in the low 90s.

LONG TERM /TUESDAY THROUGH FRIDAY/. As of 350 PM EDT Friday .

The period begins Monday night into Tuesday with an upper ridge slowly sliding offshore as an upper low traverses across the Deep South. This upper low gradually pushes ewd Wednesday into Thursday, with the global models either having this feature moving across GA/SC Wednesday then off the Carolina Coast Thursday (03/12z ECMWF/CMC), or moving from the Tennessee Valley Wednesday to the central Appalachians Thursday (03/12z GFS). Global ensemble guidance generally shows near average 500mb heights (with a positive anomaly from the Great Lakes to ern Canada), and a slightly negative MSLP anomaly in vicinity of the Southeast coast. Global deterministic models and ensemble guidance trends toward a trough in vicinity of the East Coast by the end of the week, but individual details are quite different amongst individual guidance. Forecast PoPs are generally less than 15% NE to 30-40% SE Tuesday, ~20% NE to 40-50% SW Wednesday, 20-30% NE to ~40% SW Thursday, and ~20% NE to 30-40% SW Friday. Temperatures Tuesday through Friday are forecast to be near seasonal averages, with highs in the upper 80s to low 90s (mid 80s at the immediate coast) and lows in the upper 60s to low 70s.

AVIATION /02Z SATURDAY THROUGH WEDNESDAY/. As of 815 PM EDT Friday .

VFR conditions expected through the 00z taf period. FEW to SCT cloud cover could develop for RIC after midnight but should diminish before sunrise. For SBY, a complex of storms to the north is expected to move SE/SSE tonight and diminish in intensity. There is a slight chance of light showers making it to SBY between 03-09z but confidence is too low to reflect in the taf at this time. Cloud cover will increase for SBY with cloud bases 5-10 thousand ft and will continue to increase through the afternoon, possibly becoming BKN. There is a slight chance cloud bases drop to MVFR (2500-3000 ft) between 14-20z at SBY. Otherwise, expect isolated to scattered thunderstorms to begin to develop tomorrow afternoon region- wide with cloud cover increasing. A brief drop to MVFR ceilings and/or visibility will be possible with any storm. Winds are generally light and variable or W/NW and will become N by morning, NE by afternoon, ENE by late afternoon at around 5-10 kt.

Outlook: Mainly VFR conditions will prevail Sun, but isolated to sctd showers/storms will be possible in the aftn into early evening that may result in brief flight restrictions.

MARINE. As of 350 PM EDT Friday .

Winds are light and variable this afternoon across area coastal waters. A backdoor will move down the coast tomorrow. Winds will turn NE 10-15 kt for much of the day on Saturday. High pressure will move over the region Sunday and winds will return to light and variable (less than 10 kt). The high pressure center will slide off the coast early next week and winds will become southern around 10 kt.

Waves in the Chesapeake Bay will be 1-2 ft, and seas across the Atlantic coastal waters will be 2-3 ft until early next week.

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.
