SAT...GOOD FM 3 THRU 9 PM. LATEST RUN FM GFS 18Z CYCLE SHOWS WEAKER
CAA AND LATER FROPA THAN 12Z RUN. TEMPS WARM TO 75 PRIOR TO FROPA
AROUND 11:30 AM SATURDAY WITH TEMPS HOLDING AT 71 DEG F 18 THRU 21Z
COMPARED TO EARLIER 12Z RUN...WHICH HAD TEMPS IN BRO 64 DEG F DURING
THIS TIME FRAME. MRNG LOWS FM 18Z RUN SHOW 2 DEG F HIER THAN
PREVIOUS RUN...WITH LATEST SATURDAY MRNG LOW AT BRO NEAR 44 DEG F.
POPS ALSO AT CAT LWR FM 18Z RUN.

CURRENT FCST WITHIN LIMITS...WITH NO SUBSTANTIAL CHANGES NEEDED.
&&

.PREV DISCUSSION...MUCH OF THE ACTION THE NEXT SEVEN DAYS WILL BE IN
THE NEXT 48 HOURS AS A STRONG COLD FRONT MOVES THROUGH DEEP SOUTH
TEXAS. DIGGING UPPER TROUGH OVER THE ROCKIES IS INDUCING A LOW
PRESSURE AREA AND FRONTALGENESIS OVER WEST TEXAS THIS AFTERNOON. THE
THROUGH STEADILY PUSHES EAST TONIGHT WITH THE FRONT TO FOLLOW SUIT.
SHORT RANGE MODELS DIFFER ON TIMING WHICH MAY PLAY HAVOC WITH
TEMPERATURES ESPECIALLY HIGHS. NAM/WRF INDICATES AT HIGH OF 81 AT
KBRO WITH THE GFS/MAV SHOWING A HIGH OF 69. THIS IS ONLY A THREE
HOUR DIFFERENCE ON THE FRONTAL PASSAGE TIMING. SHOWERS AND
THUNDERSTORMS THAT DEVELOP ALONG THE LEADING EDGE OF THE FRONT COULD
ALSO PLAY A FACTOR IN HOW WARM THE PREFRONTAL ATMOSPHERE GETS. WILL
SHOW HIGH TEMPS FROM MID TO LATE MORNING WITH FALLING TEMPS THROUGH
THE REST OF THE AFTERNOON. ANOTHER FLY IN THE OINTMENT WILL BE THE
SHARP CLEARING LINE BEHIND THE FRONT. THIS COULD ALLOW FOR WESTERN
AREAS TO RECOVER FOR A FEW HOURS BEFORE A MORE RAPID FALL OVERNIGHT.
AS FOR THE RAIN KEPT THE LOW TO MODERATE CHANCE IN FOR TOMORROW.
ALTHOUGH THE MOISTURE IS NOT PROGGED TO BE THAT DEEP...THE LIFT FROM
THE FRONT AND A STRONG UPPER JET NEAR BY SHOULD BE SUFFICIENT TO
PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS. BRISK NORTHERLY WINDS
WITH SOME GUSTS AROUND 30 MPH SHOULD PERSIST 2 TO 5 HOURS BEHIND THE
FRONT. WINDS DIMINISH OVERNIGHT WITH TEMPERATURES CONTINUING TO
FALL. MINIMUMS RANGE FROM THE MID 30S ACROSS THE NORTH TO LOWER 40S
ALONG THE COAST BY SUNDAY MORNING. DO NOT THINK ANY FREEZES WILL
OCCUR OVER THE NORTH OR FAR WEST DUE TO SOME RESIDUAL BOUNDARY LAYER
WINDS NOT ALLOWING FOR OPTIMAL RADIATIONAL COOLING.

CLEAR...DRY AND COOL SUNDAY WITH SURFACE HIGH SETTLING OVER THE
REGION. RETURN FLOW LATER MONDAY AND INCREASING ON TUESDAY. MODELS
SUGGEST SLIGHT CHANCE OF SHOWERS TUESDAY AND WILL KEEP THE 10
PERCENT POPS...BUT MOST AREAS WILL LIKELY TO SEE NO RAIN. MILD AND
HUMID AIR TO RETURN THE REST OF THE WEEK WITH A THURSDAY FRONT NO
LOOKING TO REMAIN NORTH OF THE REGION OR BE VERY WEAK IF IT DOES
DECIDE TO MOVE THROUGH. FOR THE REST OF THE WEEK NEAR TO SLIGHTLY
ABOVE NORMAL TEMPS AND NO SIGNIFICANT CHANCES OF RAIN ARE SEEN AT
THIS TIME.
