.NEAR TERM...
(Now through Wednesday)
Issued at 421 AM CDT Tue Jun 18 2024

Well the forecast has certainly trended drier the next couple of
days as the upper ridge over the western Atlantic noses into the
area. The reason for the stronger than originally advertised ridge
is the presence of Potential Tropical Storm one over the Bay of
Campeche/southwestern Gulf. While this system will likely drift
westward into Mexico over the next couple of days, the heat
released from this storm is aiding in strengthening the ridge of
high pressure. Kinda like a car exhaust on a car engine. As a
result, the ridge promotes more subsidence and slightly drier
conditions the next 48 hours. The only rain chances today and
tomorrow will likely be confined to the immediate coastline where
moisture will be rich enough and the influences of the ridge will
not be as strong. Otherwise, most of the area is expected to be
dry the next 48 hours. However, PTC one will have an impact on
area beaches as waves will be on the general increase leading to a
HIGH risk of rip currents and large breaking waves at the beaches
leading to a high surf advisory. BB/03

SHORT and LONG TERM...
(Wednesday night through Monday)
Issued at 421 AM CDT Tue Jun 18 2024

An elongated upper ridge extending from the western Atlantic to
the southern Great Plains will slowly sag southward through Friday
night, and then retrograde westward over the weekend with upper
troughing advancing eastward over the northern Great Plains and
Great Lakes regions. Much of the precipitation will stay out over
the Gulf through Friday, but we do expect isolated to low-end
scattered showers and thunderstorms mainly in the afternoon in
association with the sea-breeze boundary pushing inland with the
best chances remaining across our coastal zones. Rain chances look
to increase over the weekend (20-40%) and especially on Monday
(60%) due to increasing weakness aloft as the upper ridge
retrogrades westward.

Daily highs will stay warm in the lower to middle 90s through
Friday, pushing into the middle to upper 90s (about 3-7 degrees
above normal) over the weekend into early next week. Overnight
lows remain toasty with generally lower to middle 70s expected. A
High Risk of rip currents will remain in effect through at least
Friday. Surf heights will remain around 5 to 7 feet during this
period. /22

For the tropics, there`s a couple areas of interest to watch over
the next week. The first is in association with PTC1 in the
southwestern Gulf of Mexico. This system will remain well to our
southwest and the only impacts from it will continue to be
increased surf heights through Thursday and rip currents through
late week into the weekend. Late week into the weekend models
continue to be divergent on their solutions for the southwest
Atlantic system. The good news is it appears the system is further
east than anticipated initially, which means the odds of it
staying well east of the forecast area are increasing. MM/25

.MARINE...
Issued at 421 AM CDT Tue Jun 18 2024

A moderate to strong east-southeasterly flow will persist
throughout the marine zones through Thursday in response to PTC
one in the Bay of Campeche and a large area of high pressure over
the southeast. Small craft conditions with near gale force gusts
will persist through most of the week with seas also increasing to
around 7 to 9 feet offshore with 2 to 3 feet in nearshore bays
and waterways. Winds and seas are expected to slowly diminish by
the weekend. BB/03
