Fxus61 klwx 191353 aaa afdlwx area forecast discussion... Updated national weather service baltimore md washington dc 953 am edt Mon aug 19 2019 Synopsis A weak surface boundary will linger over the area through the middle of the week. Southerly flow will continue to usher in hot and humid conditions into the region during this time. A cold front will sweep through the area during the second half of the week, with canadian high pressure building in for the weekend. Near term through tonight Continued hot and humid conditions this afternoon with high temperatures in the middle 90s and heat indices between 100-104. As for convection, the nssl-wrf arw has been doing an excellent job the past few days depicting the mode and where convection has occurred. For today, it shows convection developing east of the blue ridge mtns south of i-66 and tracking east toward the potomac river and southern md. The 12z iad sounding showed decent 0-6km shear of 32kt with a speed MAX of 35kt at 500 mb which is double the amount of shear there was yesterday. Cape should be plentiful with middle 90s and 70f dewpoints. Expect a few more severe storms today than the past couple of days. Aviation 14z Monday through Friday Episodes of subVFR conditions possible each afternoon and evening through Wednesday in passing showers and thunderstorms, some of which could be strong to severe. Patchy fog will also yield reduced vsby's (MVFR ifr) during the early morning hours, especially near the terminals that receive rainfall the day prior. Outside of convection, winds will be light and south southwesterly through Wednesday.

Thursday will feature a higher risk of thunderstorms compared to Friday thanks to a passing cold front, but the risk will continue Friday if the front stalls. Marine Sub SCA conditions expected through the first half of Wednesday as light southerly flow prevails. Thereafter, southerly flow increases as a cold front approaches from the northwest, with sca gusts possible late Wednesday afternoon and overnight. Showers and thunderstorms will also be possible each afternoon and evening, bringing the potential for strong gusty winds and hail. Highest coverage of storms over the waters will be on Tuesday and again on Wednesday. Sca may continue Thursday as front approaches, but may abate Friday, especially if the front stalls.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
