Fxus61 klwx 141839 afdlwx area forecast discussion national weather service baltimore md washington dc 239 pm edt Mon oct 14 2019 Synopsis High pressure will build from the tennessee valley toward new england through Tuesday while a secondary cold front approaches from the great lakes and weakens. A strong area of low pressure will move across the ohio valley Wednesday, then re-develop over southeastern virginia and move up the coast toward new england Wednesday night into Thursday. High pressure will follow Friday into the weekend. Near term through tonight High pressure building east from the tennessee valley this afternoon and tonight. Dewpoints have dropped into the 30s due to west winds near 10kt. Winds will diminish tonight, setting up another favorable radiational cooling night. Have undercut the guidance mean, with forecast lows in the upper 30s-lower 40s outside of the urban centers next to the bay. Short term Tuesday through Wednesday night Expect another sunny day Tuesday under the firm control of high pressure. Clouds will spread into the area Tuesday night in advance of dual-stream low pressure. As for the precipitation itself, though, guidance continues to delay onset. Have backed off a little more Tuesday night, keeping forecast essentially dry except for the charlottesville staunton waynesboro area. A sharp trough axis across the great lakes Wednesday will sweep across the mid atlantic, supporting the passage of a surface cold front. Meanwhile, a second area of low pressure will cross the southern conus, strengthening as the low reaches the coast and interacts with northern stream energy. Have categorical pops across the board, but the focus will be more on the coastal during the afternoon hours. Have decent shear and minimal cape, so have included a slight chance of thunder across the entire forecast area as well. Winds will increase (a core of 40 kt winds likely below 5000 ft behind the front) and skies will clear Wednesday night as deepening low pressure ejects northeast. Upslope showers likely. These should be rain showers, but the peaks will drop close to freezing by Thursday morning. Long term Thursday through Monday Low pressure will be pulling northeastward away from the region on Thursday as high pressure builds eastward into the ohio valley. The pressure gradient between these two features will lead to blustery northwest flow and cool temperatures, with highs only in the 50s to low 60s. High pressure will then build overhead Friday and Saturday leading to sunny skies and dry conditions. Temperatures will be chilly at night with lows in the 30s 40s, and near to slightly below normal during the day, with highs in the 60s. The surface high will then slide offshore on Sunday with southwesterly return flow developing. This will usher in increasing warmth, to be followed by increasing moisture Sunday night and Monday as a low organizes in the central us. Rain chances will then

increase Sunday night and Monday. Highs Sunday and Monday will rebound back into the 70s, with lows in the 40s 50s. Aviation 18z Monday through Saturday Vfr conditions should prevail through Tuesday. May have some patchy river valley fog tonight, but do not believe it will impact the terminals. Clouds will increase Tuesday night in advance of a cold front Wednesday. A short period of flight restrictions near the time of the frontal passage possible... Likely during the midday hours. Would not rule out a rumble of thunder either. Otherwise, vfr will prevail through Wednesday night. Winds will increase Wednesday night as well. If the core of the winds do not mix to the surface, then a low level wind shear set-up would be possible. PredominantlyVFR conditions are expected Thursday through Saturday as high pressure builds eastward and into the region. Main aviation weather concern will be gusty northwest winds Thursday. Marine Winds will be light through Tuesday and then increase from the south (10-15 kt) Tuesday night. Low pressure cold front crosses the waters Wednesday. Could be convective gusts near the front; marine warnings possible. Then, in northwest flow behind the front, small craft advisories highly likely and gales possible. Small craft advisory conditions are likely Thursday with gale conditions continuing to be possible behind a low pressure system that will be exiting to the northeast. Small craft advisory conditions may linger into Friday before slackening Saturday as high pressure crests. Tides coastal flooding Water levels under a foot above astronomical normals this afternoon. Should be little change through Tuesday. Expect some caution stages to be reached but no inundation. There is a window for tides to increase Wednesday before a strong cold front crosses the area. Would not rule out minor flooding at sensitive locations prior to the frontal passage Wednesday afternoon. Lwx watches warnings advisories Dc... None. Md... None. Va... None. Wv... None. Marine... None. Synopsis... near term... Hts short term... Hts long term... Mm aviation... Hts mm marine... Hts mm tides coastal flooding... Hts

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
