Updated national weather service baltimore md washington dc 1014 am edt Sat aug 17 2019 Synopsis An upper-level ridge will build overhead through Monday, with surface high pressure in the atlantic. Hot and humid conditions will persist during this time. The upper-level ridge will gradually weaken Tuesday and Wednesday before a cold front passes through Thursday. High pressure will return for late next week, bringing noticeably cooler and less humid conditions. Near term through tonight Heights aloft will continue to rise with temperatures trending upward. Scattered showers are expected over northeast md and the blue ridge mts where differential heating boundaries are noted with isold coverage elsewhere. Otherwise, hot and humid with temperatures in the 90s approaching 100f in a few places. Short term Sunday through Monday night The heat and humidity continue to rise Sunday and Monday as southerly flow persists around the high over the western atlantic. Temperatures will increase a touch each day, with low to middle 90s being observed. This will result in heat indices cracking the century mark, in the low 100s and currently forecast just under heat advisory criteria. Will have to monitor this the next couple of days should dewpoints temps run a touch higher than currently forecast. A little strong shortwave swings across the area Sunday, so have increased pops slightly over nne maryland, with scattered showers and thunderstorms possible Sunday afternoon and evening. Another shot of showers and thunderstorms will exist Monday afternoon evening as well, but with even weaker lift aloft, the main trigger will be left to terrain circulations. As such will favor along and west of the blue ridge for scattered showers and thunderstorms, diminishing overnight Monday. Long term Tuesday through Friday The upper-level ridge will gradually break down Tuesday through Wednesday as an upper-level trough digs over the great lakes. Surface high pressure will remain over the atlantic during this time. Therefore, hot and humid conditions will persist and with lower heights in place, this will increase the chances for showers and thunderstorms. Some storms may be strong to perhaps even severe due to high amounts of instability from the hot and humid conditions. However, confidence remains low this far out. The upper-level trough will continue to dig south and east into |
the northeast CONUS as well as the mid-atlantic. The cold front associated with this system is also likely to pass through during this time, bringing chances for more showers and thunderstorms. High pressure behind the front is expected to build overhead for Friday, bringing noticeably cooler and less humid conditions. Aviation 14z Saturday through Wednesday MVFR ifr vis CIGS are plausible at the terminals the next few mornings as a warm and moist airmass lingers over the region. Afternoon evening showers and storms could yield episodes of sub vfr conditions, but coverage is expected to be too isold for taf inclusion at this time. With high pressure situated over the western atlantic, a light southerly flow will prevail through Monday. High pressure will remain over the atlantic, but an upper-level trough will build overhead. This will increase the chances for showers and thunderstorms each day, especially during the afternoon and evening hours. Marine High pressure over the western atlantic will deliver a light southerly flow over the waters, thus SCA conditions not expected through Monday. Gusty showers storms are possible each afternoon evening, however much of the time is expected to remain dry. High pressure will remain over the atlantic for Tuesday and Wednesday, causing a south to southwest flow over the waters. Winds may come close to SCA criteria at times due to southerly channeling.

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. |
