Update...
Pacific cold front has entered far western areas of the County Warning Area. A thin
line of showers has developed ahead of it across The Hill Country.
Aircraft sounding data out of aus and Sat indicate a weak 800-700mb
cap still in place. Forecast soundings indicate this eroding through
18z and am expecting deeper convection with chances for thunderstorms
to develop this afternoon east of I-35 as the front and line of
convection progresses east. A marginal risk for severe storms will
be limited to far eastern counties this afternoon.

On the back side of the front, mid level analysis reveals slight
stronger westerlies than previous anticipated. Forecast soundings
out near del Rio indicate deep mixing this afternoon all the way up
through 700mb. Momentum Transfer of 35 kts downward will likely yield
some wind gusts around 30 mph at the surface across the far
northwest County Warning Area mid afternoon through early evening, at the same time
relative humidity values are bottoming out near 10-15 percent. This will result in
critical fire weather conditions across Val Verde and potentially
portions of Edwards and Kinney counties. Have issued a red flag
warning through 7 PM for these counties.
