...New NEAR TERM, SHORT TERM, LONG TERM, MARINE...

.NEAR TERM...
(Now through Monday)
Issued at 242 PM CDT Sun Jul 14 2024

Latest water vapor imagery shows a mid level trough swinging into
the Lower Mississippi Valley with mid level ridging off the SE US
coast. Persistent southwesterly flow has allowed an abundance of
moisture to filter into the region, with PW values above the 90th
percentile for this time of year (>2.15 inches). Showers and
thunderstorms are developing over central Mississippi, along a
convergence axis and enhanced by shortwaves rotating around the
eastern periphery of the trough. Expect this activity to move into
our northern counties over the next couple of hours. Meanwhile,
isolated thunderstorms were developing along the seabreeze which has
lifted to near the I-10 corridor. Thunderstorms are expected to
dissipate this evening with the loss of daytime heating. Outside of
thunderstorms, temperatures will continue to climb this afternoon,
warming into the mid 90 to upper 90s. Heat indices will reach 105 to
110 degrees and a Heat Advisory remains in effect until 7 PM.
Overnight lows will fall into the lower to mid 70s, except along the
coast where lows will remain in the upper 70s.

The upper level trough will remain over the region on Monday, with
several shortwaves moving through the area. This will keep a higher
confidence and coverage of thunderstorms over the area through the
day, with the best chances during the afternoon as the seabreeze
moves inland and provides a focus for convection. Temperatures will
be similar to those today, with highs warming into the lower to mid
90s once again. Heat indices will be in the 105 to 110 degree range
again on Monday. /73

SHORT AND LONG TERM...
(Monday night through Saturday)
Issued at 242 PM CDT Sun Jul 14 2024

The initial trough moving through the area on Monday will gradually
weaken and flow aloft will briefly become zonal. Despite this, weak
shortwaves will continue to move through the region, bringing a
greater coverage for afternoon convection each afternoon. By
Wednesday, a trough over the Northern Plains will amplify as it
moves eastward, with a weak surface front trailing from its parent
low over the Great Lakes. The trough will move eastward through the
latter part of the week, sending the front eastward and into the
region by Thursday. Model consensus is decent enough to warrant
definite PoPs in for the latter half of the work week, when the
the trough begins to move through the area. Confidence on just how
far south the front makes it and the timing of it is low, so high
PoPs will continue into Saturday as well. Temperatures through
the period will be a tad cooler, given the lower heights, cloud
cover, and rain potential. Expect highs in the upper 80s and
overnight lows in the lower to mid 70s. /73

&&

.MARINE...
Issued at 242 PM CDT Sun Jul 14 2024

Light winds will follow a diurnal pattern into mid
week with onshore flow during the day and offshore flow at night.
Expect light southwesterly to westerly winds early next week.
