Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1005 AM EDT Tue Mar 31 2020

SYNOPSIS. Low pressure pushing swiftly across the Deep South today will move offshore of South Carolina this evening, then pass well south of the region on its way out to sea tonight into Wednesday. High pressure will slowly build in from the Midwest through the end of the week. The high will gradually move offshore over the weekend. A cold front may approach from the Ohio Valley by early next week.

NEAR TERM /THROUGH WEDNESDAY/. High pressure is located well to the north in Canada this morning, with a lobe extending toward the Mid Atlantic. A backdoor boundary is near northeast Maryland, while an inverted trough extends northward along the Appalachians from low pressure over Alabama. The low will progress across the deep south today ahead of an upper level trough.

Some light radar echoes are nearing the Baltimore metro as the backdoor boundary seeps to the southwest. Meanwhile rain to the southwest ahead of the low will slowly advance to the northeast, though it will take some time for the atmosphere to saturate. Measurable rain will hold off until at least mid-afternoon for most. A narrow corridor near the Potomac river may end up between both moisture sources until this evening, if not through the bulk of the event. Will evaluate PoPs as new guidance arrives. Low clouds have filled in across the north and high clouds are fairly dense across the south, so there probably won't be much sun to be seen today. Considered lowering high temperatures, but given the earlier overcast and higher starting point to temperatures, we aren't too far off from expected highs in the 50s, so minimal adjustments will likely be needed.

Tonight, the backdoor front will cross the region as it gets entrained in the circulation of the stronger low passing to the south. Meanwhile, some modest warm advection and jet dynamics associated with the low to the south will also move into the region. Thus, rain and drizzle is likely in most of the region, though the heaviest precip is likely in central and western VA. Amounts will be light overall, however, with totals unlikely to exceed a half inch anywhere in the region. There is just enough cold air available for a light dusting at the higher elevations, but generally an inch or less, so no winter weather advisories are necessary. Lows tonight will be in the 30s to near 40s.

Dry northeasterly flow from high pressure to the north will start to allow precip to end from northeast to southwest late tonight into Wednesday morning as the low heads out to sea, so much of the region will be dry for the bulk of the day. Lingering upper level energy combined with another weak front dropping southward from the north may bring a few more showers late in the day Wednesday into Wednesday night, especially near and west of I-81. Highs Wednesday will be similar to Tuesday, with 50s common.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/. Low pressure heads away allowing high pressure to build in Wednesday night through Thursday night. Clearing skies should allow temps to drop into the 30s Wednesday night, but sunshine Thursday should let temps rebound to near 60. Dry and mostly clear Thursday night with temps again mostly in the 30s to low 40s.

LONG TERM /FRIDAY THROUGH MONDAY/. Generally split zonal flow aloft is expected during the long term period. A surface ridge axis will move slowly from the Midwest across the Mid-Atlantic Friday and Saturday, then move offshore Sunday. A cold front will likely follow Sunday night into Monday, but guidance continues to trend slower and weaker with this feature.

The next appreciable chance of rain may not come until a bit more amplified upper-level trough and associated surface frontal system approach during the early to middle portion of next week.

AVIATION /14Z TUESDAY THROUGH SATURDAY/. VFR to start, but conditions deteriorate late today into tonight as low pressure approaches from the south and a backdoor cold front drops in from the northeast. Possible MVFR cigs could arrive at BWI/MTN faster than progged with the backdoor front, though less certain if they would make it to IAD/DCA. IFR likely tonight at most terminals with low clouds and light rain/drizzle, though some chance MTN/BWI stay MVFR. As the low heads out to sea Wednesday and drier air behind the backdoor front becomes dominant, conditions should improve, and remain VFR Wednesday night through Thursday night.

VFR conditions are expected Friday into Saturday with light northwesterly flow as high pressure builds overhead.

MARINE. SCA conditions likely to develop at least on part of the waters tonight into Wednesday as a low pressure passes to the south. After a lull late Wednesday, another front combined with high pressure building in likely leads to another period of SCA conditions late Wednesday night and Thursday. Winds should diminish as high pressure builds Thursday night.

Dry weather with light northwesterly flow is expected Friday into Saturday under building high pressure.

TIDES/COASTAL FLOODING. The tide forecast is riddled with uncertainty tonight into Wednesday due to distant but deep low pressure expected to pass south and east of the region. Generally onshore flow would result in increasing water levels. But the exact direction and strength of the winds, as well as the timing of a wind shift to a more northerly to northwesterly offshore direction will determine exactly how high water levels are able to get over the next several tide cycles.

Right now, it appears at least minor inundation is most likely for the Wednesday morning/midday high tide cycle.
