SYNOPSIS
High pressure will return Thursday and Friday. A warm front will lift into the area this weekend bringing a significant warm up early next week. The next chance for widespread precipitation arrives with a cold front Tuesday into Wednesday next week.
NEAR TERM /THROUGH TONIGHT/
A trailing shortwave is evident on water vapor imagery near Pittsburgh early this evening. At the surface, a secondary cold front arcs from NE PA into N WV. A few extra clouds, perhaps a couple sprinkles or a shower or two, and a wind shift to NNE with some 15-25 mph gusts are expected with these features later tonight. High pressure will builds over the Great Lakes, and cold advection will continue in northerly flow with temperatures dropping back into the upper 30s to mid 40s.
SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
High pressure will continue to build to our north tomorrow into Friday. As the high slowly shifts eastward, winds will turn from northeasterly tomorrow morning, to easterly tomorrow afternoon, and then southeasterly on Friday. No precipitation is expected through the daylight hours Friday. In general, a mix of sun and clouds is forecast, with cloudier skies further south and west, and more sunshine further north and east. High temperatures both days will be in the upper 50s to lower 60s, with lows generally in the 40s. The next chance for showers will come Friday night as warm advection ensues aloft ahead of a system over the center of the country.
LONG TERM /SATURDAY THROUGH WEDNESDAY/
A tale of two seasons this weekend as a warm front lifts through the region. Feeling like Summer Sunday through Tuesday with the next widespread chance of rain arriving midweek.
Surface high pressure will continue to nudge south and east off the southern New England coast into the western Atlantic for the start of the weekend. Meanwhile, at the surface a warm front will lift north along the western periphery of the surface high and push toward the eastern Great Lakes Saturday into Sunday. This front may lend to a few showers mainly along and west of the Blue Ridge although it should remain relatively moisture starved with upper level ridging quickly building in from the southeastern U.S. High temperatures Saturday will range from the upper 50s and low 60s north of I-66/US-50 with mid to upper 60s further south. This spread is due largely in part to the placement of the boundary and eroding wedge/easterly component mainly east of the Blue Ridge.
A true tease to Summer arrives Sunday-Tuesday of next week as strong upper level ridging builds over the Mid-Atlantic region. With strong surface high pressure off the NC coast an ample supply of warm air advection will surge our way boosting temperatures into the upper 70s and low 80s Sunday and potentially pushing toward 90 degrees in some locations early next week. These temperatures will be 10 to 15 degrees above normal for late April standards. Overnight lows will fall into the 50s and 60s.
The ridge begins to buckle Tuesday as a strong cold front approaches from the Ohio River Valley. The front will bring renewed chances for widespread showers and thunderstorms across the region. With that said, severe weather could become a possibility given the well above normal temperatures and modest dynamics Tuesday afternoon and evening as the front passes. CIPS analogues and the CSU Machine Learning probabilities continue to highlight this potential 7 days out with low probabilities especially in areas east of I-81. We'll continue to monitor this threat and see how it evolves over the coming days ahead.
AVIATION /00Z THURSDAY THROUGH MONDAY/
VFR conditions are expected through Friday. Winds turn northerly and then northeasterly tonight, with a few gusts of 15-20 kts possible 03Z-09Z behind a secondary cold front. Winds start out northeasterly tomorrow, then turn easterly tomorrow afternoon. Brief MVFR CIGs are possible, mainly for northern terminals in the morning. Winds on Friday will be out of the southeast.
VFR conditions are expected at all terminals Friday with high pressure overhead. East to southeast winds will gust to 15 kts.
A warm front lifts into the area Saturday providing a few spotty showers to terminals west of the corridor. Outside of the showers expect extra mid and high level clouds from time to time with southerly winds gusting 20 to 25 kts. Less cloud cover is expected Sunday and Monday as ridging strengthens. Winds will remain elevated out of the south and southwest with gusts to 15 kts.
MARINE
Winds turn north-northeasterly tonight, and SCAs remain in effect through Thursday morning. Sub-SCA northeast and then easterly winds are by expected tomorrow afternoon. Sub-SCA southeasterly winds are expected on Friday, though channeling is possible late in the day.
Winds could flirt with SCA criteria for a few hours on both Saturday and Sunday. A warm front will lift across the waters Saturday changing the winds toward more of a southerly direction. With surface high pressure off the Carolina coast expected, southerly winds Saturday to change to more of a southeasterly direction Sunday. Gusts of 15-20 kts are expected Saturday with 20-25 kt gusts possible Sunday due to southerly channeling. Sub-SCA level winds return Monday before SCA level winds return ahead of a strong cold front Tuesday.
TIDES/COASTAL FLOODING
Northwesterly winds are causing tidal anomalies to drop. As a result, no coastal flooding is expected over the next day, with only Action stage possible at the most sensitive sites. Winds turn easterly tomorrow, and then southeasterly on Friday. This may cause water levels to increase again, making coastal flooding possible by Friday.
