.DISCUSSION...
Issued at 1047 AM CDT Tue Sep 29 2026
Our taste of Fall is quickly coming to an end as we see a pattern
change the rest of the week. Today and Wednesday should remain
mostly dry, with perhaps an afternoon shower or storm near the
coast Wednesday as moisture return begins. Afternoon highs today
and tomorrow remain well above normal in the upper 80's to lower
90's, with morning temperatures Wednesday starting in the lower
60's inland and upper 60's nearer the coast. Ample moisture
return will be ongoing Wednesday night rapidly increasing
dewpoints, which should help to keep lows in the upper 60's to
lower 70's which is about 5 to 10 degrees above normal.
As we head into late week, we'll see a quick uptrend in chances
for rain Thursday through the weekend. This is thanks to deep
layer southerly winds bringing in ample tropical moisture off the
gulf along with the remnant trough split and several other subtle
disturbances rounding the periphery of the ridge. Forecast
guidance is fairly robust on overall rain totals Thursday through
the weekend, generally depicting widespread 1 to 3 inch amounts,
locally higher. The environment will be very favorable for intense
rainfall rates with storms. Sampled forecast soundings depict a
deep, warm and moist airmass supportive of efficient warm rain
processes that will be present across the area along with very
high PWATs for this time of year exceeding 2.3 to 2.5 inches. It's
still early to pinpoint what areas see higher or lower totals,
but given the environment in place I can't rule out some potential
for flash flooding, particularly in poor drainage and urban areas
that see repeated rounds of storms. MM/25

VFR conditions will prevail throughout the
period thanks to an approaching high pressure which will keep skies
mostly clear. Generally, winds will be out of the NE over the region
before gradually shifting more easterly overnight. Uncertainty with
Sea Breeze boundary advancement today will effect general wind
direction at and around JKA, though wind speeds should not
approach any critical thresholds. /31
