DISCUSSION
Issued at 223 PM EDT Wed Apr 17 2024

The dry and stable weather pattern continues as mid level ridging in the Gulf of Mexico and surface high pressure in the Atlantic continues to remain in place. By late week, there will be some flattening of the ridge as a large upper level low drifts across northern Ontario and our flow aloft will transition from northwesterly to more of a westerly (zonal) orientation for the upcoming weekend. Meanwhile, this upper level low in Canada and the associated low pressure system will drive a cold front across the Eastern Seaboard by the weekend and as this occurs, the Atlantic high pressure will shift further offshore with the surface ridge axis setting up to the south of the area. With a gradual uptick in deeper moisture and a mostly WSW flow in place for the weekend, there may be a few light showers that develop in our interior areas as the sea breeze collision occurs over the eastern side of the peninsula. This also seems to be supported by recent guidance showing some potential for light pockets of QPF over the weekend associated with some of this sea breeze activity but for now will hold off on adding any PoPs to the official forecast as confidence still remains low.

By late weekend, a southern stream shortwave trough will swing across the lower Mississippi Valley and this will support the development of a surface low around the northern Gulf Coast. This surface low will quickly shift off to the northeast as it moves offshore of the Carolinas and rain chances will increase area-wide as the aforementioned cold front slides southward across the peninsula on Monday. Models then show the frontal boundary sliding south of the area by Monday night with drier air then building into the area as high pressure builds in from the north. While there will also be some slightly cooler air in the wake of the frontal boundary, particularly for the northern half of the area, temperatures are generally expected to remain normal through the end of the extended forecast period as any cold air advection behind the front looks limited at this time.

AVIATION
(18Z TAFS)
Issued at 111 PM EDT Wed Apr 17 2024

Onshore winds will develop at coastal sites by late afternoon as the sea breeze pushes inland, but winds will become variable tonight and fall to 5 kts or less. SE winds will then be in place Thursday morning before the sea breeze allows winds to shift onshore again by Thursday afternoon with winds around 5-10 kts through the day. Otherwise, high pressure in place will maintain VFR conditions throughout the TAF period.

MARINE
Issued at 223 PM EDT Wed Apr 17 2024

High pressure in the Atlantic will remain in place through the end of the week, providing warm and dry conditions across the coastal waters and favorable marine conditions. Winds shift to the west-southwest by the weekend as a cold front ahead of a cold front that is expected to arrive by Monday and bring the next chance of rain across the area, but no headlines are expected at this time.

FIRE WEATHER
Issued at 223 PM EDT Wed Apr 17 2024

Minimum RH values will continue to drop below critical levels through the remainder of the week in inland areas as a dry air mass remains in place, though wind speeds will be light enough to preclude any red flag concerns. Humidity values will finally start to recover by the weekend as winds become southwesterly ahead of a cold front that is expected to arrive by next Monday, which will bring the next chance of rain across the region.
