AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
257 PM CST SUN JAN 10 2016

.SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...
ANOTHER COLD NIGHT IN STORE AFTER A COOL DAY ACROSS SOUTH CENTRAL
TEXAS. SURFACE HIGH PRESSURE CONTINUES TO DOMINATE THE REGION AND
WILL RESULT IN CALM WINDS OVERNIGHT AND DEWPOINTS IN THE UPPER 20S
AND LOW 30S. VIS/WV IMAGERY SHOWS SOME ELEVATED MOISTURE MOVING
EAST INTO THE AREA TONIGHT WHICH WILL BRING SOME HIGH CLOUD COVER.
THIS MAY PLAY A SMALL LIMITING ROLE IN HOW LOW TEMPERATURES GET
TONIGHT...ESPECIALLY FOR THE NORTHERN HALF OF THE COUNTY WHERE THE
BEST COVERAGE IS ANTICIPATED. HOWEVER...MODEL ENSEMBLE ANALYSIS
AND GUIDANCE SUGGESTS THAT FREEZING TEMPERATURES COULD REACH AS
FAR SOUTH AS OUR SOUTHERN BORDER WITH CRP. THIS WOULD CAUSE A
NUMBER OF OUR SOUTHERN BORDER COUNTIES TO REACH THEIR FIRST FREEZE
OF THE SEASON. THEREFORE A FREEZE WARNING WILL BE NEEDED FOR THESE
COUNTIES.

MONDAY WILL BE VERY SIMILAR TO TODAY BUT WITH MORE CLOUD COVER
OVER THE AREA. OUR NEXT H5 SHORTWAVE WILL PASS OVER THE STATE AND
OTHER THAN POTENTIALLY GENERATING SOME SHOWER ACTIVITY ALONG THE
TEXAS COAST...PERHAPS EVEN OUR EXTREME SOUTHEASTERN ZONES...WILL
PASS BY WITHOUT NOTICE. EXPECTING HIGHS PERHAPS 3-4 DEGREES
WARMER THAN TODAY ACROSS THE AREA.

&&

.LONG TERM (TUESDAY THROUGH SUNDAY)...
AFTER THIS LATEST SHORTWAVE TROUGH TRANSLATES EAST AND OUT OF THE
AREA...500 MB HEIGHTS INCREASE ABOUT 10 DM IN ADVANCE OF THE NEXT
WAVE. SHOULD RESULT IN A MUCH WARMER TUESDAY AFTERNOON.

ON WEDNESDAY...AT THE 850 MB LEVEL...HIGH PRESSURE OVER THE GULF
OF MEXICO DEVELOPS AND GENERATES SOUTHEASTERLY RETURN FLOW WHICH
SHOULD COME IN LINE WITH MODEST LIFT ASSOCIATED WITH THE UPPER LOW
POSITIONED OVER WEST TEXAS. THE BROAD REGIME OF DYNAMIC LIFT AND
DECENT MOISTURE SHOULD AGAIN PRODUCE SOME POP CHANCES FOR MAINLY
SOUTH OF THE I10 CORRIDOR EAST OF I35. WHILE LAPSE RATES ARE
FAIRLY STEEP LATE WEDNESDAY AFTERNOON...FORECAST SOUNDINGS TO NOT
INDICATE HARDLY ANY ELEVATED INSTABILITY...SO HAVE LEFT THUNDER
OUT OF THE FORECAST FOR NOW. ALSO...DYNAMICAL LIFT LOOKS PRETTY
WEAK AS WELL.

ANOTHER BRIEFLY DRY PERIOD THURSDAY BEFORE YET ANOTHER SHORTWAVE
QUICKLY PASSES OVER FRIDAY. THIS ONE IS ASSOCIATED WITH A MORE
DEFINED COLD FRONTAL PASSAGE. RIGHT NOW...GFS HAS THIS FRONTAL
PASSAGE ENTERING THE CWA 12Z FRIDAY MORNING WITH ECMWF OVERNIGHT
THURSDAY NIGHT. AT THE MOMENT...NOT MUCH QPF GENERATION BEING
ADVERTISED WITH THIS SYSTEM HOWEVER.
