AREA FORECAST DISCUSSION National Weather Service Wakefield VA 238 AM EDT Sun Aug 9 2020

SYNOPSIS. A weak surface boundary will remain across southeast Virginia and northeast North Carolina through today, before dissipating on Monday. High pressure settles over the area early this week.

NEAR TERM /THROUGH TONIGHT/. As of 230 AM EDT Sunday .

Latest analysis shows a stalled frontal boundary right along the VA/NC line early this morning, with surface high pressure to our west. Last evenings heavy rain over the southern half of the area combined with calm winds will result in areas of fog early this morning. Issued an SPS from Richmond south to start, and will monitor the trends over the coming hours to see if a dense fog advisory is needed. Any fog that develops should dissipate by around 13Z this morning. The frontal boundary will remain in the vicinity of the area today, although should continue to weaken as the upper level trough pulls further away to the east. Coverage of afternoon/early evening convection should be less than Saturday, with the highest chances again focused over the southern half of the area. The steering flow will remain light, so isolated flooding will continue to be a concern especially in urban and poor drainage areas. High temps in the upper 80s to around 90, and low temps Sunday night in the upper 60s to lower 70s.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. As of 230 AM EDT Sunday .

Surface high pressure settles over the TN valley on Monday and Tuesday, with a surface trough over the local area both days. Most of the area will be dry on Monday with just widely scattered afternoon/early evening storms over inland portions of the area. Storm chances increase on Tuesday as a weak wave aloft moves across the area. High end chance pops focused over inland portions during the afternoon and early evening tapering off to slight chance near the coast.

High temps Monday will be in the lower 90s, and right around 90 for Tuesday. Low temps Monday and Tuesday night will be in the upper 60s NW to lower 70s SE.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. As of 315 PM EDT Saturday .

A fairly typical summertime pattern looks to prevail for the medium range period Tue night through Sat, though chances for rain will tend to be a bit higher than the typical climatology as high pressure moves offshore and a series of weak troughs aloft periodically pass through the region. While the bulk of the convection will be diurnally driven (mainly aftn- evening), at least a low chance will persist overnight, especially Fri-Sat as a frontal boundary is progged to stall in the vicinity of the mid-Atlantic. 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 Thu-Sat. Wed will be the hottest day with highs mainly 90-95F, whiles highs drop back to the upper 80s/around 90F Thu-Sat (there is some potential that Sat could end up cooler over the N depending on where the frontal stalls). Lows mainly between 70-75F with some upper 60s possible in the Piedmont through the period.

AVIATION /07Z SUNDAY THROUGH THURSDAY/. As of 115 AM EDT Sunday .

Areas of fog and low stratus are expected this morning. Expect MVFR/IFR conditions at all terminals after 06Z until around 13Z when ceilings and visbys improve to VFR. Conditions should remain VFR through the rest of Sunday with just a slight chance of showers/storms in the afternoon and early evening primarily over the SE portions of the area. Winds will be light and variable through the period.

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

MARINE. As of 230 AM EDT Sunday .

A stalled frontal boundary across the waters today will slowly dissipate by Mon. High pressure returns through Thurs.

Outside of isolated thunderstorms, S-SE winds aob 10 kts expected through the period, although some southerly channeling is possible in the Ches bay late Tue. Waves 1-2 ft. Seas around 2 ft.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
