PREV DISCUSSION... /ISSUED 310 PM CST THU NOV 26 2009/
DISCUSSION...
ANOTHER FEW MILD DAYS AHEAD BEFORE MORE SEASONAL OR BELOW SEASONAL TEMPS
RETURN... AND PERHAPS A FEW SNOWFLAKES IN THE NORTHWEST. A STORM
SYSTEM MOVING INTO THE PACIFIC NORTHWEST TODAY WILL SPLIT WITH ONE
PART MOVING EAST ACROSS THE NORTHERN PLAINS WITH THE OTHER
STRONGER PART DIVING SOUTH AND CLOSING OFF OVER SOUTHERN
CALIFORNIA. AS THIS OCCURS LEE TROUGH WILL STRENGTHEN...
INCREASING SOUTH SOUTHWEST WINDS THROUGH THE SOUTHERN PLAINS ON
FRIDAY. ALTHOUGH RIGHT NOW IT APPEARS THAT WIND SPEEDS WILL REMAIN
LOW ENOUGH TO PRECLUDE THE NEED TO ISSUE ANY FIRE WEATHER
HEADLINES FOR FRIDAY. TEMPS WILL CLIMB INTO THE 70S WITH AFTN
RELATIVE HUMIDITIES DROPPING BELOW 20 PERCENT ACROSS THE WEST FRI
AFTN. WILL CONT TO MENTION HIGHER FIRE CONCERNS IN HAZARDOUS
WEATHER OUTLOOK.
COLD FRONT APPROACHES NORTHWEST OK SAT AFTN AND WILL SEE ANOTHER
VERY MILD DAY ACROSS THE AREA ON SATURDAY. AGAIN WINDS WILL BE UP...
BUT INCREASING LOW LEVEL MOISTURE WILL KEEP HUMIDITIES HIGHER. COLD
FRONT PUSHES ON SOUTH THROUGH THE AREA SUNDAY MORNING WITH PRECIP
CHANCES INCREASING THROUGHOUT THE DAY... ESPECIALLY ACROSS THE
SOUTHEAST. STILL A QUESTION AS TO HOW COLD THE COLUMN WILL BECOME
SUNDAY... BUT WILL MAINTAIN RAIN/SNOW POSSIBILITY ACROSS NORTHWEST
ON SUNDAY AND SLIDE THIS FARTHER SOUTHEAST SUN NIGHT.
DRIER AIR WILL BRING PRECIP CHANCES TO AN END MOST PLACES EARLY ON
MONDAY WITH PERHAPS A CHANCE FOR A FEW SHOWERS LINGERING ACROSS THE
RED RIVER VALLEY. OTHERWISE MOST LOCALES WILL NOT MAKE IT OUT OF THE
40S MONDAY. AT THIS POINT IT APPEARS THAT BOTH THE GFS AND ECMWF
BEGIN TO BRING THE CLOSED LOW TO OUR SOUTHWEST TOWARD NORTH TEXAS.
THIS COULD RESULT IN A FEW MORE RAIN SHOWERS ACROSS SOUTHERN PARTS
OF THE AREA. THEN MAIN STORY WILL BE CONTINUATION OF BELOW NORMAL
TEMPS FOR MUCH OF NEXT WEEK.
