Good
Afternoon Folks…
Breezy
southerly winds continuing to pump in plentiful amounts of Gulf moisture into
central and south central Texas ahead of our next approaching upper level storm
system and its associated surface cold front.
Returning moisture combined with an approaching upper level
disturbance (pocket of cold air aloft) will trigger a chance for
showers and thunderstorms across the area late this
evening into early Thursday morning.
With
this in mind, the Storm Prediction Center (SPC) has placed ALL of central and
south central Texas (including the Austin/San Antonio Metro Areas) under a
MARGINAL RISK for severe weather tonight (large hail and damaging wind gusts
being the primary threats). A marginal risk is the lowest risk of severe
weather possible, slight risk of severe weather comes into play from Waco north
into the Great Plains, those areas shaded in yellow will have a better chance
of seeing severe weather.
Dark Green = Marginal Risk
Yellow = Slight Risk
The
Storm Prediction Center defines a MARGINAL RISK as
such:
“Isolated severe thunderstorms possible that will be limited in
duration and/or coverage and/or intensity…Thunderstorm winds of 40-60 mph
possible, hail up to 1” in diameter possible, LOW tornado risk”
Storm
Timeline:
The
cold front, or lifting mechanism for the showers/storms will approach the
northwestern Hill Country after 9 p.m. and approach the I-35 corridor after 11
p.m. and areas east of I-35 after midnight. Storms will be possible along and
just behind the frontal boundary.
Storms
should be long gone by sunrise Thursday as breezy northerly winds transport
cooler and drier air into the area.

Highs
on Thursday only forecast to reach the upper 60s/lower 70s area wide with a
breezy north wind gusting 20-30 mph…temperatures drop into the 40s area wide
Thursday night under a clear sky as winds relax.
