000 FXUS61 KAKQ 241045 AFDAKQ Area Forecast Discussion National Weather Service Wakefield VA 645 AM EDT TUE MAY 24 2016 .SYNOPSIS... Low pressure will move northeast off the New England coast during today, while high pressure builds in from the west. High pressure will move right over the area tonight...then slides off the coast for Wednesday afternoon into Friday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Early this morng, sfc low pressure was sitting well off the New Jersey coast. That low will move away to the ne during today just off the New England cst. One last piece of energy/associated lift on the back side of the departing low will provide slgt to chc pops for showers ovr the nrn and ern portions of the region thru abt 8 or 9 am. Otherwise, expect increasing sunshine and warmer temps acrs the area. Highs will be in the upr 70s to lwr 80s. In that warmth, lingering weak instabilty, and one last upr lvl disturbance rotating thru behind the upr trof, there could be an isltd shower or tstm this aftn. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... Broad upper level ridging builds northeast from the Deep South into the Mid-Atlantic and Southeast region Tonight into Wednesday, before sliding overhead into Thursday. 850mb temperatures rise to ~15C by Wednesday afternoon...and 16-17c by Thursday afternoon. BL mixing will reach to around 850mb, and should result in highs reaching the mid/upper 80s inland, with low/mid 80s closer to the coast, and upper 70s for the immediate Atlantic coast of the Ern Shore. After morning lows in the 50s to near 60, high temperatures creep up about a category area wide into the upper 80s/around 90 inland (low to mid 80s coastal sections) on Thursday. Forecast soundings/model cross-sections indicate rather dry conditions aloft,owing mainly to subsidence and light downslope flow aloft. Will therefore keep pops in silent range <10% on Wed, with only slight chc for more seasonally typical diurnally-driven pulse convection on Thursday afternoon and early evening. Light downslope flow will likely keep areal coverage of any convection on the low side, and will also serve to mix dewpoints down into the mid/upper 50s in the mid to late afternoon hours both Wed/Thu. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... Bermuda sfc high pressure resides over the wrn Atlantic Ocean through the long term periods as mid-upper level ridging moves over the ne CONUS during this time. Although the GFS is trying to develop low pressure over the Caribbean/Bahamas during Thu night/Fri and then tracking it into the Carolinas Sat-Mon, the ECMWF is keeping this system suppressed farther south due to mid-upper ridging well-rooted across the ne CONUS through at least Sun night before beginning to impact the Mid Atlantic Region. WPC forecast is also very similar to the ECMWF and am starting to lean more twd this warmer and drier solution... especially since GFS ensembles support the GFS as more of an outlier at this point. Will trend the long range forecast in this direction regarding precip and temperatures. High temps continue to run above normal throughout the extended forecast periods and are now closer to being around 10 degrees above normal Fri (highs in the upper 80s inland...upper 70s to mid 80s immediate coast). For Sat-Mon, temps are around 5-7 degrees above normal (highs in the mid 80s Sat/Sun and lower 80s Mon). Low temps also still trending around 5-10 degrees above normal Thu-Sun nights (lows generally in the mid 60s). && .AVIATION /12Z TUESDAY THROUGH SATURDAY/...

Sfc lo pres off the mdatlc cst will cont to track ne and away fm the rgn through tda. Drier air fm the W sloly spreads ovr the fa through tda...resulting in VFR conds. Very lo prob for isold tstm ern VA...lwr SE MD this aftn/early eve. A much more summer like pattern is expected for the rest of the week. VFR conditions expected mostly, however one could not rule out some fog at night especially with all of the moisture from recent rains.
