319 PM CDT Wednesday Jul 23 2014

latest radar composites show cluster of storms over Wharton...Fr
Bend and Colorado counties. These storms have been pulsing up and
down and are moving from NE to SW being steered by flow aloft. One
of these cells when it collapsed produced fairly strong winds
with a few trees down west of Bay City...but have been mostly
characterized by wind gusts of 20 miles per hour or so with some very heavy
downpours and lightning. Another hot day with heat indices
currently in the 95 to 100 degree range...and likely set to rise
another 5 degrees or so.

Would need heat index of 108f forecast for two consecutive days
to trigger a heat advisory for our warning area...and think will
approach those values next 4 days or so in the afternoon...but
more likely top out around 105f. For this reason dont plan to
issue a heat advisory for area. will be hot and
humid and protective measures should be taken. Precipitation chances
tomorrow will be much like today...with isolated to scattered
activity mainly near and south if Interstate 10...and almost any
time of the day...but with slightly greater coverage in the
afternoon with daytime heating. As upper high tries to build in
from the northwest...a slight cap develops...more pronounced over northwest
zones...which should mean little or no thunderstorm activity for
the weekend...although cant rule out isolated storm along sea
breeze...with likely 10 percent or less coverage.

Once we get to next week...a cold front approaches from the
northeast and heights fall. This will allow for a tad cooler
conditions and better chances of rain starting perhaps as soon as
next Monday and certainly Tuesday and Wednesday. Have indicated
slightly higher precipitation chances for NE zones at this time with 30
pop NE...20 pop southwest. These will be adjusted as we get closer
to that period. 46


mainly south to southwest winds are anticipated for the remainder
of the week and through the upcoming weekend. More periods of showers
and thunderstorms are possible through the end of the week as a
disturbance moves slowly across the waters...then a dry weekend is
anticipated as high pressure builds across the area. Slightly
stronger onshore winds (generally 10 to 15 knots) are still in the
forecast at the end of the week and over the weekend. Flags are
still not anticipated. 42
