AREA FORECAST DISCUSSION National Weather Service Wakefield VA 116 AM EDT Sat Aug 8 2020

SYNOPSIS. A weak surface boundary will remain near the local area through Saturday. This boundary will allow for additional showers and thunderstorms with locally heavy rainfall possible. High pressure settles over the area late in the weekend. Widely scattered afternoon thunderstorms will again be possible early next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/. As of 1000 PM EDT Friday .

Continuing to monitor convection to our west and also a cluster of showers and storms moving south . all of which continues to weaken. Have chance PoPs north and west through 06z to account for this. Otherwise, expecting no worse than isolated to widely sct coverage of shwrs through the same time. Any lingering activity will the diminish after 06Z. Lows tonight are expected to range from the mid to upper 60s NW to the low to mid 70s SE. With the threat of heavy rain diminishing have also cancelled the Flash Flood Watch as of 10 pm.

SHORT TERM /6 AM THIS MORNING THROUGH MONDAY/. As of 355 PM EDT Friday .

The stationary front lingers over the region Saturday, providing another chance for diurnal storms to develop by the afternoon. Due to very low FFG WPC has majority of the CWA in a marginal risk for excessive rainfall. Will refrain from issuing a Flash Flood Watch for Saturday at this time due to uncertainty in coverage. Otherwise, any storms should begin to diminish Saturday night. High in the mid to upper 80s and lows in the mid to upper 60s NW to the low 70s SE.

Sunday will be a bit warmer with highs in the upper 80s to low 90s. There will be a chance for more isolated to scattered storms to develop by the afternoon, due to the stationary front still lingering, with the greatest chance in the SE VA/NE NC but with less coverage than prior days (PoPs 30-40%). Any storms dissipate overnight with lows in the mid to upper 60s NE to the low 70s SE.

Monday will be the warmest of the short term with highs in the low 90s. There is only a slight chance of storms in SE VA/NE NC, but most will remain dry. Lows Monday night will range from the upper 60s NW to the low 70s SE.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. As of 345 PM EDT Friday .

Still looking like a more typical summertime pattern for the medium range period (Mon night through Fri). The large scale pattern through much of the period will feature high pressure (at the surface and aloft) offshore of the SE CONUS coast. At the beginning of next week, weak upper troughing is progged to be centered in the vicinity of the Mississippi River Valley. The main upper level flow will remain well to our north (mainly near or just north of the US/Canada border). The area of upper troughing will slowly approach the area from the west next week. This will allow for diurnal (mainly aftn-evening) tstm chances to continue from Tue-Fri. Will generally trend PoPs slowly upward from Tue-late next week as the weak upper trough nears the area. Will cap PoPs at 50% in the grids for now, while noting that the blends have likely PoPs for much of the forecast area during the aftn-evening on Thu/Fri. Highs Tuesday in the low-mid 90s, falling back into the low 90s on Wed. Highs around 90F on Thu/Fri with increased cloud cover/tstm chances. Lows mainly between 70-75F through the medium range period.

AVIATION /05Z SATURDAY THROUGH WEDNESDAY/. As of 110 AM EDT Saturday .

Brief flight restrictions early this morning due to scattered convection across the area. Sub VFR ceilings and visbys possible early this morning, especially at SBY where heavy rain has occurred over the past couple hours. Outside of convection, winds will be light and variable. Ceilings/visbys improve across all terminals by late this morning. Additional scattered storms expected this afternoon and evening, but chances are too low to mention in this TAF cycle.

Outlook . Mostly VFR conditions expected Sunday into early next week outside of isolated afternoon/evening storms which could result in brief flight restrictions.

MARINE. As of 345 PM EDT Friday .

Benign marine conditions continue through the weekend with a weak front lingering over the area. The wind will generally be S aob 10kt, but could briefly become N/NW late Saturday night/early Sunday, and again late Sunday night/early Monday if the front can push far enough south. Southerly flow prevails early next week with high pressure centered off the coast. Seas will generally be ~2ft, with 1 foot waves in the Bay, and occasionally 1-2ft at the mouth of the Bay.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
