.DISCUSSION...
COLD FRONT WILL CONTINUE TO PLUNGE SOUTHWARD FASTER ON ITS WESTERN
SIDE THAN ITS EASTERN SIDE. SURFACE PRESSURE GRADIENT BETWEEN A HIGH
OVER THE NORTHERN BLACK HILLS AND A LOW OVER NORTHERN NEW MEXICO
WILL CONTINUE TO BE TIGHT THIS MORNING WHICH WILL ALLOW THE FRONT TO
DIVE SOUTHWARD ACROSS THE WESTERN PANHANDLES FIRST EARLY THIS MORNING
AND THEN THE FRONT WILL FILTER SOUTHWARD ACROSS THE EASTERN CWA WITH
TIME LATER THIS MORNING AND EARLY THIS AFTERNOON. THE COOLEST
TEMPERATURES WILL BE ACROSS THE NORTHWEST WHERE THE STRONGEST COLD
AIR ADVECTION WILL BE.

SUBTROPICAL PLUME COMBINED WITH THE LIFT FROM THE FRONT AND UPSLOPE
FLOW WILL KEEP THE RAIN CHANCES GOING...ESPECIALLY FOR THE SOUTHEAST
HALF OF THE PANHANDLES TODAY. THE RAIN WILL DECREASE FROM NORTHWEST
TO SOUTHEAST LATE THIS AFTERNOON INTO EARLY THIS EVENING.
TEMPERATURES TONIGHT WILL FALL INTO THE LOWER TO MID 40S DESPITE
THE CLOUD COVER. A FEW UPPER 30S WOULD NOT BE OUT OF THE QUESTION
IN THE WESTERN OKLAHOMA PANHANDLE...ESPECIALLY IF SOME BREAKS IN THE
CLOUDS MATERIALIZE.

UPPER LEVEL TROUGH WILL SWING TO THE NORTHEAST OF THE PANHANDLES
STARTING SATURDAY...SO UPPER HEIGHTS WILL RISE AND SO WILL THE
TEMPERATURES.

NEXT CHANCES OF RAIN ARRIVE MONDAY AND THEY SHOULD STICK AROUND
THOUGH AT LEAST TUESDAY NIGHT. A NORTHWEST FLOW COMBINED WITH
INCREASED MOISTURE AND SEVERAL MINOR SHORT WAVE TROUGHS SHOULD
HELP TO ENHANCE THE RAIN CHANCES. UPPER RIDGE NUDGES EASTWARD
AND COVERS THE PANHANDLES BEYOND TUESDAY...SO WILL KEEP THE
FORECAST DRY.

&&

.FIRE WEATHER...
NO ELEVATED OR CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED THROUGH
THIS WEEKEND GIVEN THE CHANCES OF RAIN TODAY AND THE ELEVATED
RELATIVE HUMIDITY VALUES.
