/ISSUED 355 AM CDT TUE JUN 27 2017/  
 
DISCUSSION...  
A FEW STRONG TO OCCASIONALLY SEVERE STORMS ARE MOVING SOUTHWARD  
ACROSS SOUTHERN KANSAS AND NORTHERN OKLAHOMA EARLY THIS MORNING.  
STORMS APPEAR TO BE DEVELOPING ALONG A NOSE OF SLIGHTLY STRONGER  
85H WINDS/WARM AIR ADVECTION. ALTHOUGH STORM MOTION IS ENHANCING  
INFLOW, STORMS ARE DISSIPATING AS THEY MOVE SOUTHWARD INTO CENTRAL  
OKLAHOMA. AT THIS TIME WILL KEEP LOW CHANCES FOR STORMS ACROSS  
NORTHERN OKLAHOMA EARLY THIS MORNING.  
 
A SHORTWAVE TROUGH WILL MOVE ACROSS THE NORTHERN AND CENTRAL  
ROCKIES TODAY WHICH WILL HELP FLATTEN THE UPPER RIDGE OVER  
THE WESTERN STATES. THIS WILL ALSO BRING MUCH WARMER 7H TEMPERATURES  
EASTERN INTO THE SOUTHERN PLAINS. THEREFORE, WARMER TEMPERATURES  
AND RATHER LOW RAIN CHANCES CAN BE EXPECTED FOR MUCH OF TODAY  
THROUGH THE FIRST HALF OF THURSDAY.  
 
LATE THURSDAY INTO EARLY FRIDAY, A COLD FRONT IS EXPECTED TO APPROACH  
NORTHERN OKLAHOMA, AS ANOTHER TROUGH MOVES ACROSS THE ROCKIES AND  
NORTHERN PLAINS. BETTER RAIN CHANCES THURSDAY NIGHT WILL BE NORTH  
AND EAST OF THE AREA, BUT SOME STORMS MAY DEVELOP OR MOVE INTO  
NORTHERN OKLAHOMA MAINLY DURING THE OVERNIGHT PERIOD. THE FRONT  
MAY PUSH FAR ENOUGH SOUTH TO REACH SOUTHERN OKLAHOMA AND NORTH  
TEXAS BY LATE FRIDAY AFTERNOON. THIS FRONTAL TIMING MAY FAVOR  
HIGHER RAIN CHANCES FOR SOUTHERN OKLAHOMA FRIDAY NIGHT INTO  
SATURDAY. WILL CONTINUE HIGHER POPS FARTHER NORTH AT THIS TIME AS  
THE EC MODEL DEVELOPS STORMS IN CENTRAL OKLAHOMA NEAR AN ELEVATED  
FRONTAL BOUNDARY. REGARDLESS, IT DOES APPEAR THE FRONT WILL BRING  
MUCH NEEDED RAIN TO AT LEAST PARTS OF OKLAHOMA. SOME OF THE RAIN  
WILL LIKELY BE HEAVY WHICH MAY CAUSE SOME FLOODING CONCERNS.  
 
THE TREND GOING INTO NEXT WEEK IS FOR MORE HOT AND DRY WEATHER.  
 
FIRE WEATHER...  
A GUSTY SOUTHERLY WIND IS EXPECTED WEDNESDAY AND THURSDAY  
AFTERNOON. THE WIND WILL COMBINE WITH RATHER LOW HUMIDITY IN  
WESTERN OKLAHOMA AND NORTH TEXAS TO ELEVATE FIRE WEATHER  
CONDITIONS DURING THE AFTERNOON/EARLY EVENING.
