A upper level subtropical ridge currently rests over the northern
Gulf while extending into the TN Valley region. Further west, a
shortwave trough is developing a surface low over the Central Plains
while troughing lingers into northern Mexico. Concurrently, a
surface ridge remains parked over the Florida peninsula which is
helping enhance southerly flow as it abuts the upstream trough. This
pattern will support mostly cloudy conditions over the next few
days. Temperatures today shall climb to the upper 70s with few
locations touching the low 80s. By Wednesday, the shortwave trough
begins to pivot across central Texas while the parent surface low
lifts up into the Great Lakes region. Nevertheless, the upper level
pattern continues to support a generous amount of moisture lifting
inland from both the Pacific and Gulf. Notably, upper level
divergence should support convective showers / storms through the
afternoon and evening hours. The storm prediction center currently
analyzes a Slight risk of severe storms between Wednesday evening
north of LA HWY 190. A Marginal risk for excessive rainfall is also
collocated over this risk area. That said, the nature of the front
appears fairly progressive, so flooding / ponding is generally
favored to common urban nuisance locations.

Behind the front winds will turn out of the north Thursday and
likely marine headlines will be needed to account for hazardous
winds / seas offshore to small craft. Inland winds and gusts will
likely range 20-30 mph through Thursday afternoon periodically
before easing that evening. Additionally, we can expect cooler
temperatures Thursday in the 60s. Southerly flow returns out of the
south Friday with temperatures rebounding to the low 80s amid dry
weather through the upcoming weekend.

(12Z TAFS)
Issued at 631 AM CDT Tue Mar 10 2026

Widespread IFR / MVFR conditions are present across the region as
moist air from the Gulf interacts with a stalled front causing low
clouds. After sunrise the cloud deck will rise to become
borderline VFR / MVFR. Through the forecast winds will slowly
increase but will remain from the south. Near the end of the
forecast a strong line of showers and thunderstorms will start to
impact the region with TSRA PROB30 in the forecast for BPT
starting at 09Z.

.MARINE...
Issued at 144 AM CDT Tue Mar 10 2026

Light southerly flow has brought a warm and moist air mass over cooler
shelf waters to bring about the potential for sea fog, reduced
visibility and low cloud development tonight. A low pressure system
will develop to the NW this afternoon that will increase the southerly
flow with winds becoming quite breezy over the coastal waters until a
Pacific cold front moves across on Wednesday. Strong north winds and
building seas will occur behind the front Wednesday night into Thursday
with potential for wind gusts over gale force.

.FIRE WEATHER...
Issued at 144 AM CDT Tue Mar 10 2026

A warm and moist air mass will remain over the region through mid
week with afternoon minimum relative humidity values over 60 percent. A
Pacific cold front will bring the chance for strong thunderstorms on
Wednesday with locally heavy rainfall. Wind turn out of the north
overnight into Thursday, becoming gusty through the afternoon before
easing at night. This brief pattern shift will lend drier conditions
through Friday before southerly flow pumps Gulf moisture inland by the
weekend.
