.SHORT TERM...
(Tonight through Saturday night)
Issued at 333 PM CDT Thu May 2 2024

As of 330CDT we are seeing showers and storms begin to taper
across the area, with a wake low forming over the northern tier
of the CWA. We will continue to see tapering across the area this
evening, however another round of showers and storms will ramp
tomorrow morning thanks to yet another disturbance. Tomorrow night
we shall see another lull in activity, which is likely to persist
into Saturday afternoon before isolated showers return to the
northern half of the CWA.

While rainfall amounts tomorrow and Saturday are not expected to
be as copious as what we have seen today, we continue to stress
that any additional rainfall amounts will exacerbate current
flooding.

.LONG TERM...
(Sunday through next Wednesday)
Issued at 333 PM CDT Thu May 2 2024

The long-term portion of the forecast period begins with the
potential for yet another wet day, especially for the far nrn
areas, as we`ll see the interaction of an approaching/passing mid-
level shortwave with a stalled/decaying sfc boundary over the
region along with abundant Gulf moisture. Best rain chances will
come during the late morning/afternoon hours along with daytime
heating before lift wanes as the disturbance aloft departs.

For Monday, as the mid/upper-level trof pushes ewd out of the
Rockies, another weaker disturbance is progged to slip past the area,
with best dynamics staying to our north. However, could see enough
lift to go along with daytime heating to produce widely scattered
convection across our nern zones.

Thereafter, the remainder of the forecast period looks dry as a more
zonal flow is progged to develop aloft, with weak capping/limited
moisture aloft likely prohibiting convective development.

Expect to see a gradual warming trend through the long term as temps
creep upward to mins in the lower 70s/highs in the lower 90s.

.AVIATION...
(06Z TAFS)
Issued at 1132 PM CDT Wed May 1 2024

Not a lot has changed in the thinking for the aviation forecast.
Low clouds will continue to form over the next few hours with MVFR
conditions possibly down to IFR conditions.

After 02/11z or so, the forecast will depend on how the MCS
develops over Texas and how it moves across the forecast area. At
this time will cover this with TEMPO for storms at KBPT by 02/14z
and PROB30 at all remaining terminals starting at KLCH/KAEX at
02/15z and starting at KLFT/KARA at 02/16z.

If the storm complex does make it through, expect IFR conditions
with low visibility from heavy rainfall along with gusty winds.

.MARINE...
Issued at 333 PM CDT Thu May 2 2024

Isolated to slight showers and storms to continue across the
coastal waters this evening. We will see a brief lull in activity
overnight before another round tomorrow morning. Then another
quiet period starting tomorrow night. No Small Craft Advisory
criteria is anticipated with this disturbance. Otherwise, onshore
flow and mild conditions are anticipated through the rest of the
period.
