Fxus61 klwx 231404 afdlwx area forecast discussion national weather service baltimore md washington dc 1004 am edt Fri aug 23 2019 Synopsis A cold front will cross the area today and move into the southern mid-atlantic and southeast states this weekend. Strong high pressure will build north of the region tonight and settle over northern new england and atlantic canada through early next week. A tropical depression could form over the weekend as it moves near the southeast coast. Near term through tonight Initial wind shift has crossed through the region, although based on temperature dew point analysis, cold front is still slowly progressing southward and is located roughly from near luray eastward to warrenton, then northeastward to near annapolis. Slow movement southward is expected to continue through the day today. A surface wave is positioned along the boundary across central WV and this will move eastward along the front into the afternoon hours and be positioned near the southern DELMARVA by this evening. Widespread rain showers are expected across the region, and some heavier rain is possible just to the north of the surface low this afternoon as is currently being observed across central west virginia. Ahead of the front and surface low, enough instability will likely still be present this afternoon for some scattered thunderstorms, and an isolated severe thunderstorm is possible. The risk for this mainly exists across nelson and albemarle counties, possibly as far north as spotsylvania and st. Mary's counties. Temperatures will be considerably cooler, with mainly locations north of the front already reaching their highs for the day overnight. Afternoon temperatures likely holding form the upper 60s to the mid 70s in and NW of the metros, with low 80s se. Rain showers will end from NW to SE late today and this evening with drier air filtering in overnight. Lows tonight in the 50s 60s. Short term Saturday through Sunday night High pressure will build north of the region tonight and hold strong through early next week. It should be pleasant and mainly dry, but areas along the lower chesapeake bay may still have a slight risk of a shower or two due to onshore flow. Long term Monday through Thursday For the most part, high pressure will be in control of the weather and provide dry and slightly cooler conditions Monday through Tuesday. An onshore flow from the western atlantic could spawn a few showers or a thunderstorm, mainly Tuesday and across the potomac highlands. The high pressure will move to the northeast Tuesday night and Wednesday. A cold front will approach the region from the west. Ahead of the front, the warmth and humidity will return due to a developing and persistent southerly flow. A chance for additional showers and thunderstorms will be present, especially Wednesday afternoon and evening.

The cold front is expected to push to the southeast and move offshore the east coast Thursday. A cooler dome of high pressure will build behind the front from the upper midwest and great lakes region. Cooler and drier air will ensue with this high.

A few stronger thunderstorms are possible near cho this afternoon. Conditions will improve tonight. Vfr conditions for all terminals Monday through Tuesday night. Any isolated shower or thunderstorm could briefly bring conditions to MVFR and probably would be mainly near mrb or cho Tuesday. Winds northeast 5 to 10 knots Monday, then variable Monday night. Winds southeast around 5 knots Tuesday and Tuesday night. Marine Northerly winds will increase as a front moves southward across the waters and a SCA is in effect across portions of the lower tidal potomac and chesapeake bay through this evening. In addition, some smws may be required for the far southern waters this afternoon as scattered thunderstorms are possible. Improving weather tonight as cold front pushes south, but additional northerly flow will create SCA conditions later tonight into Saturday. Will also need to monitor northerly channeling and potential TC passing offshore early or mid next week for increasing winds and possible scas. No marine hazards expected Monday through Tuesday night. Winds northeast 10 knots Monday, then light and variable Monday night. Winds becoming southeast 10 knots Tuesday and Tuesday night.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
