.PREV DISCUSSION... /ISSUED 516 AM CST SAT DEC 26 2009/ 

SYNOPSIS...A MODIFIED POLAR HIGH PRESSURE CELL DIRECTILY OVER THE
AREA WILL BE SPLITTING OFF INTO A RIDGE ON SUNDAY WITH BUILDING
HIGH PRESSURE OVER TEXAS. A DRY NORTHERLY FLOW WILL CONTINUE TO
BRING COOLER THAN NORMAL TEMPERATURES UNDER SOME JET CIRRUS ALSO
KNOWN AS THE PINEAPPLE EXPRESS ASSOCIATED WITH THE SUBTROPICAL JET.

THIS ACTIVE SOUTHERN STREAM WILL KEEP FORMING UP COASTAL LOWS OFF
TEXAS WITH THESE FRONTAL WAVES PRODUCING OVERRUNNING RAIN OFF THE
COAST ON SUNDAY AND AGAIN OVER THE ENTIRE AREA AROUND THE MIDDLE
OF THE WEEK AS A STRONGER LOW MOVES OFF THE COAST.

SHORT TERM...TRIMMED BACK PRECIP CHANCES TNITE AS THE LOW LOOKS
TO BE SUFFICIENTLY WEAK AND SOUTH TO ONLY PRODUCE OVERRUNNING
PRECIP OVER THE COASTAL WATERS AND POSSIBLY AS FAR NORTH AS THE
I-10 CORRIDOR.

LONG TERM...INCREASED COLD RAIN CHANCES OVER THE MIDDLE OF THE
WEEK AS BOTH THE GFS AND EURO ARE IN AGREEMENT ON THE LOW CLOSER
TO THE COAST THAN PREVIOUSLY PROGGED. BROAD AND HIGHLY AMPLIFIED
UPPER LEVEL RIDGING OUT WEST HOLDS THE PROMISE OF AN EXTENDED
PERIOD OF FAVORABLE WEATHER TO BRING IN THE NEW YEAR.
