1003pm EDT Fri August 7 2020

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 6am Saturday Morning
As of 1000pm 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 Probability of Precipitation north and west through 06z to account for this. Otherwise, expecting no worse than isolated to widely scattered coverage of showers 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 - 6am Saturday Morning Through Monday
As of 355pm 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 345pm EDT Friday... Still looking like a more typical summertime pattern for the medium range period (Monday 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 forecast 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 Probability of Precipitation slowly upward from Tue-late next week as the weak upper trough nears the area. Will cap Probability of Precipitation at 50% in the grids for now, while noting that the blends have likely Probability of Precipitation 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.

As of 345pm 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.
