...New SHORT TERM, LONG TER
Marine
.SHORT TERM... (Today through Friday) Issued at 239am CDT Thu Mar 28 2024

Axis of the upper longwave trough was moving across the area early this morning, with ridging over the Rockies. A new trough was coming onshore in the Pacific Northwest. At the surface, high pressure extended from Tulsa to Indianapolis. Temperatures at 3 AM CDT ranged from the upper 40s to mid 50s under mostly clear skies.

High pressure will continue to slide southeastward and be centered over North Florida Friday evening. Little in the way of cloud cover is expected today or tomorrow. Northerly winds will still be in place today, so it's entirely possible that the Mississippi Coast will be the warm spot 2 days in a row. In any case, high temperatures will generally be in the 70s both days. Overnight lows will remain a little bit cool tonight with lows in the 40s across most of the area. Can't rule out one or two spots falling into the 30s, or remaining near 50. The one adjustment that was made again today was to lower forecast dew points using the NBM 10th percentile, which lowers relative humidities below 30 percent across the east half of the area. Winds of 10 to 15 mph won't quite reach Red Flag criteria, but it still could produce a few problems.

Long Term
(Friday night through Wednesday) Issued at 239am CDT Thu Mar 28 2024

Upper ridging over the Gulf of Mexico will be controlling the weather through the weekend and into Monday. Don't expect much more than high clouds across the area through Sunday or Monday. Temperatures will gradually creep up a couple degrees each day. By Sunday and Monday, high temperatures will generally be in the lower or middle 80s away from direct marine influences (sea breeze), with lows in the 60s.

Tuesday into Wednesday will see an upper trough extend from the Great Lakes to the Texas Panhandle. This will push a cold front through the area sometime around Tuesday night. This will bring a chance of rain Tuesday or Tuesday night, followed by drier weather and sunnier skies. Looks to be about 5 to 10 degrees cooler, but no major cold spell in store.

Marine
Issued at 239am CDT Thu Mar 28 2024

Will leave Small Craft Exercise Caution headline in place for today. Beyond today, a quiet several days anticipated on the marine side with winds generally well below advisory criteria until showers/storms arrive Tuesday.
