Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 409 AM EDT Thu Aug 13 2020

SYNOPSIS. A front will stall over the Middle Atlantic today, then drift southward Friday into Saturday. The front will then lift back northward through the end of the weekend as low pressure lifts into the Ohio River Valley.

NEAR TERM /THROUGH TONIGHT/. Stalled front in the vicinity combined with a tropical air mass and passing shortwave energy promises to make the next few days interesting. For this morning, a fairly significant vort max and shortwave will move through shortly. This is already starting to cause storms to develop, and expect coverage to expand northward, maxing out during rush hour. Locally heavy rain is very possible and given the rain we had yesterday in some areas, a flash flood watch seemed prudent. Ran the watch through this evening as expect more storms to fire in the afternoon, but highest coverage likely occurs this morning with the shortwave. Exhaustion of CAPE and modest height rises/anticyclonic flow this afternoon likely keep coverage a bit reduced. Some sun will break through, but highs will only be in the 80s. By comparison, tonight looks like we will be between upper level features, so evening convection will diminish and do not expect a refiring overnight. Lows in the 60s to 70s.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. Front will make some southward progress Friday night through Saturday night as upper low to the west strengthens/sharpens. This will result in better afternoon storm coverage Friday, and then better rain/storm coverage overall Saturday. As the atmosphere being tapped is not going to change, even if the immediate low level one does somewhat behind the front, expect the heavy rain threat to persist through Saturday night. With the continued clouds and storms, highs will continue to be in the 80s, with Saturday being the cooler day as the front drops further south. Lows will be in the 60s to 70s, not much change.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The aforementioned frontal boundary continues to lift northward on Sunday, with low pressure riding along it across the area into Sunday evening. This will again bring thunderstorms to the area. Heavy rainfall again will be possible with these. Temperatures will be well below average on Sunday, with highs struggling to reach 80 for most.

Beyond Sunday, looks like a brief lull in activity could occur early in the week. However, still a great deal of uncertainty there, as the upper-level pattern remains unsettled nearby. But Monday and Maybe Tuesday could see the area in zonal flow, with less coverage of showers/storms. Highs each day in the low to mid 80s.

By the middle of next week upper-level flow may once again buckle, allowing for more disturbed weather across the region. However, timing of that is still up in the air at this point. This time of year typically brings about weakly forced events, so can be a bit tough to nail down this far out. Continue to monitor latest forecasts for new info.

AVIATION /08Z THURSDAY THROUGH MONDAY/. Patchy low clouds and fog will be an issue each of the next three late night/early morning periods as plentiful low level moisture will make its formation easy, if we have clearing. That said, higher clouds may limit this threat at the terminals. Otherwise, main concern will be for heavy downpours with lightning to produce sub-VFR conditions and gusty winds. Best coverage will generally be afternoon hours, though today, a disturbance makes storms a bit more likely in the morning.

Sub-VFR conditions expected at times on Sunday, as low pressure moves along a lifting frontal boundary over the area.

VFR conditions generally expected by Monday, in the wake of the low, but some showers and storms remain possible in the afternoon, but with less coverage.

MARINE. Generally sub-SCA conditions expected on the waters through Saturday. Main concern each day will be thunderstorms, primarily during the afternoon hours, though some may develop during the mornings. Gusty winds and even a few waterspouts will be possible with stronger storms.

SCA conditions possible on Sunday in onshore flow. By Monday, flow shifts offshore, but could remain close to (but should stay just below) SCA criteria.

HYDROLOGY. Significant rain fell in scattered areas around the CWA yesterday. While not everyone saw heavy rain, most of the CWA had some rain, so antecedent conditions are growing increasingly wet. With some locally heavy showers and storms expected this morning, it seemed prudent to issue a Flash Flood Watch, even though confidence on really heavy concentrated storms is not quite as high given somewhat reduced CAPE. Storm coverage may actually decrease significantly this afternoon, but confidence on this is not yet high. That said, would not be surprised if the watch was to be dropped early.

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.
