Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 442 AM EDT Sat Aug 8 2020

SYNOPSIS. High pressure will build across the region over the next few days. A cold front will approach from the northwest next week, stalling in the area as the week progresses.

NEAR TERM /THROUGH TONIGHT/. Frontal boundary is stalled across our area this morning, while mid to upper level trough axis is sliding east into the Mid-Atlantic region. Isolated showers and a few thunderstorms are moving over the Fredericksburg area over southern Maryland, just south of the boundary where humidity is higher along with better forcing. Cloud cover has diminished over our western zones, which is north of the boundary, and fog has started to develop over the valleys.

Additional patchy fog could develop this morning, with it dissipating after sunrise. Trough axis will be pushing east from our region today while high pressure starts building to our NW. Dry conditions are expected over most of our CWA this morning, with showers lingering between Fredericksburg and southern Maryland. With the boundary over our region but not much forcing aloft, could see a few isolated showers and thunderstorms developing due to terrain circulation -especially over central Virginia-, and also south of the boundary where the higher moisture and instability recedes.

High pressure will be building into our region Saturday night as the boundary moves into southern Virginia. A few showers could linger over our southeastern zones but should diminish as the night progresses.

Near normal high temperatures are expected for today, reaching into the upper 80s is most regions. Lower at higher elevations. Low temperatures for tonight will be in the 60s and low 70s.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. High pressure will be building overhead on Sunday as pattern remains zonal aloft, and the boundary to our south dissipates. Conditions should remain dry on Sunday, with maybe an isolated shower developing due to terrain circulation over central Virginia. Dry conditions will remain into Sunday night. High temperatures will be in the upper 80s and low 90s, with the highest heat index values reaching into the mid 90s.

Weak high pressure will remain in control on Monday but a shortwave trough aloft and southerly flow advecting moisture into our region, could allow for the development of a few isolated showers and thunderstorms. Heat index values could reach the upper 90s over most areas across our CWA.

LONG TERM /TUESDAY THROUGH FRIDAY/. Guidance is in relative agreement regarding the pattern thru the coming week, with a general increase in storminess. At the start, a relatively zonal pattern will exist aloft, with a cold front in the eastern Great Lakes. As the week progresses, the front will drop into our region and stall out, all the while a closed low develops to our west. This combination will be conducive to an increasing risk of showers and thunderstorms, with an attendant increase in the risk of isolated severe storms and flash flooding. Temperatures will start to decline, with high 80s and low 90s Tuesday dropping into the 80s by Friday.

AVIATION /09Z SATURDAY THROUGH WEDNESDAY/. MVFR and IFR conditions have developed over some terminals due to low CIGS, along with some patchy fog. This should remain for the next few hours and improve after sunrise. VFR conditions should return then and are expected to remain through the rest of the today, with any restrictions related to thunderstorms, especially near CHO. A drier pattern then builds on Saturday night and remains into Monday night with less chance of any thunderstorm developing over our region. Patchy fog possible again Saturday night.

Main aviation concern on Tuesday and Wednesday will be isolated thunderstorms, primarily in the afternoon and evening hours.

MARINE. Winds are expected to remain below Small Craft Advisory criteria into Monday night. Some convection could bring gusty winds today over the southern portion of the Bay, and lower Tidal Potomac. This should improve tonight. There will be less chance for any convection Sunday into Sunday night, a slight chance for Monday afternoon/evening.

Main marine concern on Tuesday and Wednesday will be isolated thunderstorms, primarily in the afternoon and evening hours.

TIDES/COASTAL FLOODING. Elevated water levels will persist over the next few days. A few places could barely touch minor flood stage, but overall, think action stage will be the most common high tide. With minimal flow, no significant changes are expected.

LWX WATCHES/WARNINGS/ADVISORIES. DC . None. MD . None. VA . None. WV . None. MARINE . None.

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.
