.PREV DISCUSSION... /ISSUED 226 PM CST THU NOV 26 2009/
ANOTHER CHILLY NIGHT TONIGHT AS DEW POINTS REMAIN IN THE LOWER TO
MIDDLE 30S FOR MOST OF THE AREA WITH TEMPERATURES EXPECTED TO
BOTTOM IN THE UPPER 30S AND LOWER 40S. THE SURFACE HIGH WILL
BEGIN TO SHIFT TO THE SE TOMORROW WHICH WILL TURN THE WINDS AROUND
FROM THE SOUTH. THIS WILL ALLOW TEMPERATURES TO INCREASE TOMORROW
AFTERNOON INTO THE UPPER 60S AND LOWER 70S WITH OVERNIGHT LOWS
FRIDAY NIGHT AVERAGING 50 DEGREES ACROSS THE AREA. WINDS WILL PICK
UP ON SATURDAY AS A SURFACE LOW DEVELOPS ON THE LEE SIDE OF THE
ROCKIES AHEAD OF THE NEXT SYSTEM. THIS WILL HELP WITH MOISTURE
RETURN TO THE REGION WITH DEW POINTS APPROACHING 60 DEGREES IN THE
SOUTHEAST SUNDAY AFTERNOON.
THE NEXT SYSTEM WILL MOVE ONSHORE OVER THE PACIFIC NORTHWEST
TOMORROW EVENING AS ONE ELONGATED TROUGH. AS IT PROGRESSES
EASTWARD OVER THE WEEKEND...THE SOUTHERN END OF THE SYSTEM WILL
DETACH ITSELF FROM THE MEAN FLOW AND DIG SOUTHWARD INTO THE BAJA
CALIFORNIA REGION ON SUNDAY. THE NORTHERN PIECE OF ENERGY WILL
MOVE FASTER TO THE EAST AND SEND ANOTHER COLD FRONT INTO NORTH
TEXAS SUNDAY AFTERNOON AND EVENING...AHEAD OF THE BAJA LOW.
MOISTURE LOOKS SUFFICIENT FOR RAIN ALONG AND BEHIND THE FRONT
SUNDAY AND INTO MONDAY.
THE LONG RANGE MODELS ARE IN GOOD AGREEMENT OF THE BAJA LOW MOVING
ACROSS NORTH TEXAS TUESDAY NIGHT WITH THE MODELS DEVELOPING LIGHT
PRECIPITATION WRAPPING AROUND THE LOW. THIS WOULD NORMALLY BE A
GREAT SETUP FOR WINTER PRECIPITATION FOR NORTH TEXAS WITH THE
FRONT COMING IN 36-48 HOURS BEFORE THE LOW PRESSURE SYSTEM. 850
TEMPS WILL BE WELL BELOW FREEZING...BUT ATTM...TEMPERATURES NEAR
THE SURFACE LOOK TO BE ENTIRELY TOO WARM FOR ANY FROZEN PRECIP.
STILL PLENTY OF TIME TOO WATCH THIS SYSTEM.
