Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 406 AM EDT Sun Sep 20 2020

SYNOPSIS. Canadian high pressure will build from the Great Lakes into the Northeast and Middle Atlantic through today, then gradually shift offshore during the first half of next week.

NEAR TERM /THROUGH TONIGHT/. High pressure will remain in control through tonight. Plenty of sunshine today will be followed by mainly clear skies tonight. Temperatures will be below average once again through the period. Highs will reach the middle 60s. Lows will drop into the lower 40s. Patches of frost is possible again later tonight along and west of the Blue Ridge.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. Plenty of sunshine and cooler than normal temperatures expected once again Monday through Tuesday night. High pressure will remain overhead. Highs Monday will reach the middle 60s once again, while highs on Tuesday could reach near 70.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Warmer weather will prevail through the long term as surface high pressure shifts to our south and ridging briefly builds in overhead. This will allow warmer west to southwest winds to envelop the region, with temps returning to near to just above normal with temps rising to the upper 70s to near 80 during the afternoons, dropping to the 50s by the late night periods.

It is notable that some guidance suggests that the remnants of Beta could try to bring clouds and rain into the region by the end of the week into next weekend, but confidence on this solution remains very low, and a passing front/upper level trough may end up supressing it to our south.

AVIATION /08Z SUNDAY THROUGH THURSDAY/. VFR conditions at the terminals through Thursday. A persistent northerly wind expected throughout Tuesday, shifting west to west-southwest by Thursday.

MARINE. Small craft advisories are in effect through this afternoon for the wider portion of the Chesapeake and Tidal Potomac. These may need extension.

Lighter winds will prevail Wednesday and Thursday as high pressure shifts to the south and the pressure gradient dwindles.

TIDES/COASTAL FLOODING. Tides will gradually become elevated today through Monday with a few locations possibly reaching minor flooding late today and this evening, while most others will be Monday afternoon or evening.

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.
