Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 908 PM EDT Mon Jul 13 2020

SYNOPSIS. A weak front along the Atlantic seaboard will push offshore by tonight. High pressure will then build across the area Tuesday and Wednesday before moving offshore. A front may approach from the north late in the week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. A weak frontal boundary remains along the eastern seaboard this evening. Winds at DCA/IAD have switched around to the northeast, suggesting that the front is inland and oscillating. There have been a couple of showers/thunderstorms thus far, and they have not been directly associated with this boundary. They did send out an outflow, but this activity has predominately ceased with the loss of daylight given a capped 00Z IAD RAOB. A shower/sprinkle still possible in the southeastern section of the forecast area per CAMs, but will primarily step away from precip for the first period (ie: tonight). Temp forecast on track.

SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/. On Tuesday, high pressure will be centered over the eastern Great Lakes and will be moving NE into Tuesday night. Aloft, upper trough will be over New England with its axis just east of our area and pushing away from us into the night hours. Dry conditions expected generally under light northerly flow. Temperatures will reach into the upper 80s and low 90s, except at higher elevations. With dew points in the 50s and 60s. Low temperatures overnight will be in the 60s and 70s.

High pressure will be located over eastern Canada and remain there Wednesday into Wednesday night. Aloft, ridging will be building over our area. Winds will become easterly and then southerly late on Wednesday into Wednesday night with dry conditions over most of our area. With returning warm and moist air advection, a few isolated showers and/or thunderstorms could develop over higher terrain, near central VA, however with ridging aloft may inhibit any development.

LONG TERM /THURSDAY THROUGH MONDAY/. Ridge of high pressure continues to build over the deep south Thursday through the weekend. For our area though, we remain on the outer periphery of this upper-level ridge, which will lead to a somewhat active pattern across the region.

Thursday, an area of low pressure will track well to our north across the Great Lakes into the northeast. However, the cold front associated with this system will swing through Thursday night. Ahead of the front, a pre-frontal trough also moves across the region. With a warm and somewhat humid air mass in place, showers and storms are expected. Could be a couple different rounds, with the first coming in the afternoon with the pre-frontal trough, and the second coming with the front itself later Thursday evening into Thursday night. The frontal boundary is slow to push through the area on Friday, with an upper-level disturbance moving in out of the Ohio Valley as well. This will lead to additional showers and storms on Friday as well.

Multiple disturbances embedded within northwest flow Saturday and Sunday present continued chances for showers and storms through the weekend, primarily in the afternoon/evening. So, maintaining the chance POPs each of those days.

AVIATION /01Z TUESDAY THROUGH SATURDAY/. VFR flight conditions will prevail through Tuesday with scattered-broken clouds. Am keeping any overnight fog in the mountains and away from the terminals.

High pressure will be in control through Wednesday allowing for VFR conditions across the terminals. Winds will become easterly late Wednesday into Wednesday night which may enhance cloud cover.

Generally expect VFR conditions on Thursday across the region. However, showers and storms associated with an approaching cold front on Thursday into Thursday night may lead to restrictions at all terminals for a short period of time.

This front stalls over the region on Friday, with continued rain chances. Restrictions likely on Friday as a result, but will be heavily dependent on where the front stalls exactly.

MARINE. Light NW winds/Sub-SCA conditions will continue through Tuesday. High pressure will be in control through Wednesday allowing for sub- SCA conditions across the waters. A SCA may be needed for parts of the waters on Wednesday afternoon. Will continue to monitor.

Southerly channeling could approach SCA criteria late Thursday. Winds south around 10 knots Friday and Friday night. The chance of thunderstorms will increase each day.

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.
