&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
As of 340 AM EDT Monday... Key Messages: -Near record high temperatures today. A strong upper level ridge is in place from Florida into the OH Valley with sfc high pressure anchored off the SE US coast. Cirrus early this morning dissipate by mid morning with mostly sunny skies expected today apart from some fair weather CU. Temps as of 310 AM ranged from the low-mid 60s with morning lows in the lower 60s for most (upper 50s across interior portions of NE NC). Dry and hot today with SW winds 5-10 mph N and 10-15 mph S. Highs this afternoon in the upper 80s to around 90F for most and mid-upper 80s SW. Record highs today are generally in the 90s apart from 89F at SBY (see climate section below for more information). As such, most areas will be a few degrees shy of records except SBY which may reach or exceed the daily record high. Mild tonight with lows in the upper 50s SW to the low-mid 60s elsewhere.

&& .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
-- Changed Discussion --
As of 340 AM EDT Monday... Key Messages: -Well above normal temperatures Tuesday. -Scattered showers and storms possible Wednesday with a cold front passage. Aloft, a ridge weakens Tue and Wed as a shortwave moves through. At the surface, a weak area of low pressure moves E through the Mid Atlantic and off the coast Tue into early Wed with high pressure building in behind it. This pushes a weak cold front through the area late Tue night into Wed. A few isolated showers/storms are possible across the Piedmont Tue afternoon/evening with the shortwave. Temps will once again be well above normal on Tue with highs in the upper 80s for most. SBY may once again reach or exceed the daily record high (see climate section below for more information). PoPs increase Wed morning into Wed afternoon as scattered showers/storms develop along and behind the cold front moving through the area. PoPs have trended higher (35-55%) with the best chance for rain across SE VA/NE NC where around ~0.25" of rain is possible. The rain ends by Wed evening with dry weather expected Wed night. Highs Wed will be largely dependent upon timing of the front/rain with a faster FROPA allowing for warmer temps in interior portions of the FA. For now, have highs mainly in the lower 80s inland (locally mid 80s) and upper 70s along the coast.

&& .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 230 PM EDT Sunday... Key Messages: -Above normal temperatures continue through the week. -Isolated showers/storms are possible Friday. -Shower/storm chances increase Saturday ahead of a cold front. Aloft, a ridge builds across the East Coast from late this week with above normal temps expected. At the sfc, high pressure slides off the New England coast Wed night into Thu, with onshore flow expected across the area. Any convection should quickly dissipate Wednesday evening, with mainly dry wx expected from Wed night through most of Fri. Temps on Thu are expected to be slightly cooler than they will be on Wed, with the coolest temps along the coast with the continued onshore flow. Forecast highs Thu are in the lower 80s inland with upper 60s-70s near the bay/Atlantic coast. Thu will likely remain dry. High pressure moves farther offshore from Friday through the weekend while the ridge aloft slowly breaks down. Low pressure tracking well to our NW will drag a cold front toward the area this weekend, which will result in increased chances for showers/tstms. A prefrontal trough may spark some showers/storms Fri aftn/evening with 15-30% PoPs. At this time, it looks like the best chance of storms is on Saturday with lingering precip chances on Sunday as the front may stall near/over the area. Temps remain above normal through the weekend (but not as warm as they will be tomorrow/Tue). && .AVIATION /08Z MONDAY THROUGH FRIDAY/... As of 120 AM EDT Monday... VFR conditions prevail through the 06z TAF period with mainly clear skies outside of some cirrus overnight and a few fair weather CU this afternoon. Clouds clear again Mon evening with some cirrus moving back in from the W late Mon night. SW winds will generally average 5-10 kt tonight (slightly higher near the coast). Winds increase to ~10 kt later this morning with a few 15-20 kt gusts expected across SE terminals from late morning through the afternoon. Outlook: Dry/VFR conditions are expected at all terminals from Monday night through at least Tuesday afternoon. There is a slight chance of tstms at RIC/SBY Tuesday evening, with a higher (~30%) chc of mainly afternoon/evening showers and tstms on Wednesday at all of the terminals. Very brief flight restrictions are likely in any tstm. Dry Thu-Fri. && .MARINE...

As of 230 AM EDT Monday... Generally benign, sub-SCA conditions, are expected through the forecast period. Early this morning, high pressure is centered off of the Carolinas. Winds are generally out of the SW and running around 10 to 15 knots. Seas are running around 2 to 3 feet (up to 4 feet out 20 nm), and waves in the bay are running around 1 foot (up to 2 feet at the mouth). High pressure will remain centered close to its current location through today before gradually sliding further off the southeast US coast on Tuesday. Winds will continue to average around 5 to 15 knots out of the SW today through tonight. A cold front approaches the waters later Tuesday, crossing the waters Wednesday morning. S to SW winds will increase slightly ahead of the front (~15 knots over the bay and ~15 to 20 knots over the coastal waters) Tuesday afternoon into Tuesday evening, but are expected to remain sub-SCA. Seas increase due to the stronger S winds, with seas approaching 5 feet out 20 nm, especially north of Cape Charles Light. Winds shift to the W and then NNW behind the front Wednesday morning and seas will quickly diminish. Generally light onshore flow is then expected later Wednesday into Friday. Another front potentially approaches the waters late week into this weekend.
