(This evening through Tuesday Night)
Issued at 237 PM CDT Mon Jun 17 2024

Deepening convection across the Bay of Campeche continues to
appear more organized within a broad area of low pressure that
may eventually become a tropical depression/tropical storm over
the next few days. The induced S/SEly flow across our region in
response to the deepening low pressure has resulted in tropical
moisture surging well inland over much of the western Gulf coast.
Considerable heating with afternoon temperatures in the upper end
of the 80s to lower 90s is beginning to yield more in the way of
convection compared to earlier this morning. Expect this trend of
increasing showers and thunderstorms to persist through the rest
of the afternoon through early this evening before peak heating
subsides. Low temperatures will generally range from the lower to
mid 70s with mostly cloudy skies prevailing overnight.

The presence of the aforementioned tropical low as it drifts into
the NW Gulf will serve to maintain at least low-end rain chances
across our region on Tuesday. At a minimum, look for cloud cover
to remain plentiful as rich tropical moisture continues to surge
northward across the entire western Gulf coast. Short-range progs
maintain a gradual W/NW shift of this tropical low, eventually
taking it inland along the middle Texas coast. As a result, any
heavy rainfall threat will remain to our S/SW with generally low
QPF amounts expected across our region through Tuesday night. Due
to persistent cloud cover, daytime highs will be slightly tempered
on Tuesday with mainly upper 80s to near 90s degrees while lows
overnight maintain the lower to mid 70s.

Moving into mid-week on Wednesday, some rain chances will persist
across our southern zones even as the tropical low moves farther
inland across south central Texas. However, these rain chances
will begin to dry up after that with the westward expansion of an
upper-level ridge axis across the Mid-Atlantic and SE CONUS. This
ridge will help propel temperatures back into the mid to upper 90s
range by Thursday and Friday on into the weekend just in time for
the official start of astronomical summer on Thursday. The heat
will be the main weather story from then on through the weekend,
and the possibility for heat hazard headlines will certainly need
to be considered based on the current forecast.

(18Z TAFS)
Issued at 1245 PM CDT Mon Jun 17 2024

Clouds are slowly lifting and scattering towards VFR early this
afternoon, with some mid and higher level clouds noted as well.
Expect SCT-BKN lower-end VFR ceilings/conditions through the rest
of today, with scattered showers and thunderstorms through about
sunset or shortly thereafter. Mid and high clouds likely to make
for the ceilings through most of the overnight before MVFR
ceilings attempt to spread in from the south and west Tuesday
morning. Confidence in MVFR coverage is currently on the lower end
at the time of this writing. Scattered showers may again develop
Tuesday, especially through the first half of the day. Winds
generally SE today 8-12kts gusting at times to near 20kts before
easing some overnight 5-7kts and increasing again Tuesday morning
around 10kts.
