DISCUSSION...  
WARMER WEATHER IS EXPECTED TODAY. ANOTHER WAVE MOVING TOWARD THE  
AREA IN THE NORTHWEST FLOW ALOFT WILL BRING A COLD FRONT THROUGH  
THE AREA LATE THIS AFTERNOON AND EVENING, WITH A CHANCE OF SOME  
SHOWERS, ALTHOUGH NOT EXPECTED TO BE WIDESPREAD. SOME FROST WILL  
BE POSSIBLE IN SHELTERED AREAS OF NORTHWEST OKLAHOMA. DESPITE THE  
COLD FRONT, TEMPERATURES TOMORROW WILL BE SIMILAR TO TODAY, THEN  
WARMING EACH DAY THROUGH THE WEEKEND.  
 
AND THEN THE PATTERN CHANGES. AFTER A MID-LEVEL RIDGE MOVES TO OUR  
EAST ON SUNDAY, THE AREA WILL BE DOMINATED BY SOUTHWESTERLY FLOW  
ALOFT AHEAD OF A LONGWAVE TROUGH DEVELOPING IN THE WESTERN UNITED  
STATES. THIS WILL ALLOW MUCH LONGER-DURATION SOUTHERLY WINDS AND  
ASSOCIATED MOISTURE TRANSPORT NORTH FROM THE GULF, WHICH WILL THEN  
LEAD TO THE POTENTIAL OF STORMS NEXT WEEK. MEDIUM RANGE MODELS ARE  
COMING INTO A BIT MORE AGREEMENT WITH THE TIMING, BUT IT'S STILL  
TOO EARLY TO GET TOO SPECIFIC. BUT IT DOES APPEAR THAT STORM  
CHANCES WILL BEGIN AS EARLY AS MONDAY WITH HIGHER CHANCES IN THE  
MIDDLE OF THE WEEK. THIS PATTERN TRANSITION WILL HOPEFULLY CLOSE  
THE BOOK ON THE WILDFIRE SEASON (ALONG WITH OUR RECENT RAIN  
EVENTS ACROSS WESTERN OKLAHOMA), BUT POTENTIALLY OPEN THE BOOK UP  
SEVERE WEATHER SEASON. AGAIN, IT'S TOO EARLY TO GET INTO  
SPECIFICS, BUT SEVERE STORMS ARE BEGINNING TO LOOK MORE LIKELY  
NEXT WEEK.
