SHORT TERM...
QUIET PATTERN ACROSS WEST CENTRAL TEXAS IN THE SHORT TERM. HIGH
PRESSURE SHIFTING OFF TO THE EAST WILL ALLOW LIGHT SOUTH WINDS TO
PREVAIL TONIGHT. THESE WINDS...COMBINED WITH A VEIL OF HIGH
CLOUDINESS STREAMING IN FROM THE SOUTHWEST...WILL KEEP OVERNIGHT
LOWS WARMER THAN WHAT WE HAVE SEEN THE LAST FEW NIGHTS. WARM AGAIN
ON FRIDAY.
A SHORTWAVE MOVING ACROSS BAJA CALIFORNIA THIS AFTERNOON WILL MOVE
ACROSS WEST CENTRAL TEXAS ON FRIDAY. APPEARS THAT THIS IS A FAIRLY
POTENT SYSTEM...BUT JUST DONT HAVE ANY SIGNIFICANT MOISTURE TO WORK
WITH. THUS...WILL INCREASE CLOUDS BUT HOLD OFF ON ADDING ANY POPS AT
THIS POINT.
