AREA FORECAST DISCUSSION National Weather Service Wakefield VA 1053 AM EDT Fri Aug 7 2020

SYNOPSIS. A weak surface boundary will remain near the local area into the weekend. This boundary will promote numerous opportunities for showers and thunderstorms with locally heavy rainfall possible. High pressure settles over the area late in the weekend. Diurnal thunderstorm chances continue early next week.

NEAR TERM /THROUGH TONIGHT/. As of 1050 AM EDT Friday .

Latest analysis shows an upper level trough to our west, while at the surface a stalled frontal boundary remains across the Mid Atlantic. Some patchy areas of fog are lingering in the piedmont but should dissipate before noon. A thick cloud deck has parked itself over the region this morning. Current thoughts are that this cloud deck will remain into early afternoon with a few breaks possible by mid-late afternoon. However, these breaks may allow for just enough diurnal heating to allow high temps to rebound into the mid to upper 80s. If cloud cover does not break this afternoon then temps, instability, and storm chances will be lower than expected.

Otherwise, the upper level trough will slowly progress east today, while the surface boundary will remain in the vicinity of the area. This will once again provide the focus for additional showers and thunderstorms late this afternoon and into the evening. Recent model trends are for a later onset of precipitation (especially in central Va) and therefore have adjusted PoPs to reflect this. While the coverage is not expected to be as widespread, FFG values are very low (around 1 inch/hour in the RIC and VB areas) due to recent heavy rainfall received since Monday. Because of the antecedent conditions, will maintain a Flash Flood Watch for the northern half of the area including the Hampton roads area from Noon today through 2 AM (06Z) Saturday. Convection should diminish after 06Z.

SHORT TERM /SATURDAY THROUGH SUNDAY/. As of 300 AM EDT Friday .

Upper level trough moves offshore this weekend, but the surface boundary will remain in the vicinity of the area. This will keep the chance of afternoon/evening storms in the forecast for both Saturday and Sunday. High pressure tries to settle into the area from the NW by late Sunday. High temps Saturday and Sunday generally in the upper 80s to lower 90s. Low temps both days in the upper 60s to lower 70s.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. As of 345 PM EDT Thursday .

Still looking like a more typical summertime pattern for the medium range period (Sun night through early next week). The large scale through much of the medium range period will feature high pressure (at the surface and aloft) offshore of the SE CONUS coast, with weak upper troughing remaining centered in the vicinity of the Mississippi River Valley. This will allow for temperatures to rise back to near/slightly above average by early next week. In addition diurnal (mainly aftn-evening) showers/tstms are possible each day (Mon-Thu). Will account for this with slight chc-chc PoPs. Highs generally 89-94F with lows from around 70F to the mid 70s through the medium range period.

AVIATION /15Z FRIDAY THROUGH TUESDAY/. As of 645 AM EDT Friday .

Patchy fog and IFR/LIFR ceilings early in the 12Z TAF period. Ceilings and visbys are expected to improve over the next few hours. Winds light and variable this morning becoming S/SE during the day today with wind speeds generally under 10 kts. Scattered showers and thunderstorms expected this afternoon and evening, which may result in brief flight restrictions. Sub-VFR ceilings/visbys possible again early Saturday morning.

Outlook . Mostly VFR conditions expected this weekend outside of isolated afternoon/evening storms which could result in brief flight restrictions.

MARINE. As of 300 AM EDT Friday .

Quiet marine conditions continue into the weekend despite a frontal boundary lingering across the area. S winds aob 10 kts thru Sat become N-NW by Sun behind a cold front that crosses the area Sat night. Winds return to the S aob 10 kts early next week as high pressure. Waves 1-2 ft. Seas 2-3 ft.

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.
