.PREV DISCUSSION... /ISSUED 259 AM CST SAT DEC 26 2009/ 

DISCUSSION...
NORTHERN OKLAHOMA MAY SEE SOME FLURRIES OR BRIEF PERIODS OF LIGHT
SNOWFALL TODAY ASSOCIATED WITH THE WRAP-AROUND ELEMENTS OF THE
LARGE UPPER LOW WHICH CONTINUES TO MOVE SLOWLY NORTH THROUGH THE
UPPER MIDWEST. THE MILDLY-WARMING WEST WIND OF FRIDAY WILL
CONTINUE TODAY, BUT THE WIND IS EXPECTED TO MOVE MORE NORTH SUNDAY
WHEN THE SURFACE RIDGE BUILDS TOWARD OKLAHOMA FROM THE NORTHWEST.
IN BETWEEN OVERNIGHT TEMPERATURES TONIGHT MAY BE DIFFICULT TO
FORECAST, BUT GUIDANCE GIVES NUMBERS LOWER THAN THIS MORNING GIVEN
LESS WIND SUNDAY MORNING. A MID-LEVEL, SMALL UPPER-RIDGE IS
EXPECTED TO ALLOW MOSTLY SUNNY SKIES INTO TUESDAY WHEN AN UPPER
LEVEL SYSTEM APPROACHES FROM THE WEST. THE GFS AND ECMWF SUGGEST
THAT THE MAIN INFLUENCE WILL BE TO TO THE SOUTH OF OKLAHOMA.
SOUTHWEST LOWER-LEVEL WIND FORECASTS PRESENTLY RESULT IN A CHANCE
FOR RAIN SOUTH AND SNOW NORTH WEDNESDAY. COLDER AIR FOLLOWS
THURSDAY INTO THE WEEKEND. LOW POPS ARE IN THE FORECAST FOR FRIDAY
ASSOCIATED WITH A CLIPPER-STYLE TROUGH MOVING QUICKLY NORTH AND
EAST OF OKLAHOMA.
