FOR THE EVENING UPDATE
Issued at 733 PM EDT Sat Mar 21 2026 High pressure will hold over the region for the next couple of days with continued mostly clear to partly cloudy skies and mild dry conditions. Temperatures will drop generally into the 50s tonight...with highs in the lower to mid 80s on Sunday.
DISCUSSION
Issued at 123 PM EDT Sat Mar 21 2026 Upper-level ridging is building over the western part of the U.S. this afternoon while troughing has shifted east of Florida. At the surface, high pressure has settled over the Gulf and this feature will dominate the weather over the next several days, keeping slightly above normal temperatures and dry conditions across the local area. The ridge will flatten some on Tuesday as a frontal boundary moves south over the region and this will bring slight rain chances back into the forecast through mid-week before we dry out once again for the end of the week.
AVIATION
(00Z TAFS) Issued at 733 PM EDT Sat Mar 21 2026 VFR conditions will persist tonight and Sunday under mostly clear skies.
MARINE
Issued at 123 PM EDT Sat Mar 21 2026 High pressure will remain over the region for the next several days with no headlines expected.
FIRE WEATHER
Issued at 123 PM EDT Sat Mar 21 2026 High pressure will remain over the area for the next several days, with rain-free and warming conditions expected. A relatively dry air mass will allow relative humidity values to drop to critical levels for parts of the interior through early next week, but no Red Flag conditions are anticipated as sustained winds are forecast to remain less than 15 mph. Some patchy fog is possible over the next few days.
