Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 254 PM EDT Sat Jun 6 2020 .SYNOPSIS... A cold front will push south of the area this evening. Canadian high pressure will follow for Sunday and Monday. The high will move offshore for the middle part of next week, then a frontal system will approach later next week. && .NEAR TERM /THROUGH TONIGHT/... Dry air advection is already underway as seen on microwave imagery through the Blended TPW and ALPW products. NUCAPS soundings from 1654Z derived from the ATMS sensor aboard one of the NOAA satellites also showed substantial dry air in the 850-500 mb layer and a strengthening subsidence inversion. Believe hi-res models as well as SPC Day 1 Convective Outlook are highly overdone with convective potential this afternoon. Earlier showers over northern VA and central MD have already dissipated indicative of an unfavorable thermodynamic profile downstream. Will keep very low end chance PoPs mainly focused over southern MD. Any convection that manages to develop would be isolated at best and should exit the area by around 830PM. There will be substantial height falls tonight as upper trough over the Northeast swings through, but lack of moisture and instability is just likely to result in some clouds and no precip. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... Canadian high pressure will build over the region Sunday through early Mon and result in very pleasant early summer weather. Sharp mid-upper level ridge will build over the region Tue into the middle portion of next week leading to a warming trend and increasing humidity. && .LONG TERM /TUESDAY THROUGH SATURDAY/... Dry conditions continue on Tuesday as upper level ridging remains persistent over the eastern CONUS. Temperatures at 850mb range between 19-21 degrees C which translates to surface temperatures in the mid to upper 80s. Humidity levels will begin to increase Tuesday night into Wednesday as the associated surface high begins to shift offshore; inducing a southernly flow. Simultaneously, the remnants of Cristobal will continue to track northward through the Central Plains. An upper level trough will then phase with Cristobal, creating a new surface low that will track northeastward across the Great Lakes region into southern Canada by the end of the week. The associated cold front will then cross our region late Wednesday night into Thursday; resulting in the development of showers and thunderstorms. Guidance has been suggesting that the boundary will stall over our area through Friday, before a second shortwave shifts the boundary offshore by late Friday. As a result, the risk of showers and thunderstorms remains prevalent late Wednesday through late Friday. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... Winds becoming NW and then NNW behind a frontal passage this evening. VFR conditions expected. High pressure in control of the region Tuesday and Wednesday will result in mainly VFR conditions as the flow becomes southerly. && .MARINE... A slight chance of a t-storm this evening mainly across lower Potomac River and Chesapeke Bay near Point Lookout and Smith Island. Winds increase early tomorrow with short-lived SCA conditions. High pressure over the waters is expected to keep winds generally light on Tuesday. Winds may increase Wednesday in southerly channeling ahead of a cold front; Small Craft Advisories are possible by late Wednesday. && .LWX WATCHES/WARNINGS/ADVISORIES... DC...None. MD...None. VA...None. WV...None. MARINE...None. && SYNOPSIS...LFR NEAR TERM...LFR SHORT TERM...LFR LONG TERM...MSS AVIATION...MSS/LFR MARINE...MSS/LFR
