HIGH PRESSURE ACROSS THE INTERMOUNTAIN WEST WILL CONTINUE ITS SLOW  
PROGRESSION EASTWARD OVER THE NEXT COUPLE OF DAYS...PEAKING ACROSS  
THE LOCAL AREA ON SUNDAY. AS THIS RIDGE AXIS TRANSITIONS  
EAST...EXPECT TEMPERATURES TO CORRESPONDINGLY WARM...REACHING THE  
MID 80S ACROSS MUCH OF THE LOCAL AREA SUNDAY AFTERNOON. WHILE THE  
UPPER LEVEL LOW...CURRENTLY ACROSS THE PACIFIC NORTHWEST...WILL  
EVENTUALLY PUSH THIS RIDGE EAST LATE SUNDAY INTO MONDAY...HEIGHTS  
WILL QUICKLY REBOUND BY MONDAY AFTERNOON...WITH TEMPERATURES  
LIKELY REMAINING IN THE 80S EACH AFTERNOON THROUGH AT LEAST THE  
MIDDLE OF NEXT WEEK. AS A RESULT...DRY AND SEASONABLY WARM  
TEMPERATURES WILL BE THE RULE THROUGH MUCH OF THE EXTENDED  
PERIODS.  
 
FOR TODAY...DID ADD SOME HAZE TO THE FORECAST AS SMOKE FROM THE  
WILDFIRES TO OUR WEST WILL LIKELY STILL IMPACT THE LOCAL AREA.  
WHILE MODELS RETREAT THE WORST VISIBILITIES TO OUR WEST...THINK  
HAZY SUNSHINE WILL ONCE AGAIN BE THE RULE...WITH ANY REDUCED  
VISIBILITIES LIKELY LIMITED TO AREAS WEST OF HIGHWAY 183 AS  
HINTED BY THE MODELS. OTHER THAN THE SMOKE POTENTIAL  
CONTINUING...DRY WEATHER WILL BE THE RULE ACROSS THE LOCAL AREA  
WITH THE SMALL CHANCES THAT WERE IN THE FORECAST FOR SUNDAY NIGHT  
NOW GONE...AND ONLY A HINT AT A FEW SHOWERS WITH A PASSING TROUGH  
NEXT WEDNESDAY THAT WERE GIVEN BY THE BLEND OF MODEL DATA...BUT  
REMOVED AS THE SIGNALS FOR THIS ARE BOTH WEAK AND MIXED.  
 
ONE OTHER AREA OF CONCERN IS THE POTENTIAL FOR ELEVATED FIRE  
WEATHER CONDITIONS OVER THE UPCOMING WEEKEND. AS THE WEST COAST  
TROUGH MAKES ITS WAY EAST OVER THE WEEKEND...LOW PRESSURE WILL  
INTENSIFY ON THE LEE SIDE OF THE ROCKIES...INCREASING THE LOCAL  
PRESSURE GRADIENT AND RESULTING IN BREEZY/WINDY CONDITIONS  
DEVELOPING BOTH SATURDAY AND SUNDAY AFTERNOONS. WHILE WINDS ALONE  
WILL BE NEAR CRITICAL THRESHOLDS FOR FIRE WEATHER...AT THE PRESENT  
TIME...RELATIVE HUMIDITIES LOOK TO REMAIN ABOVE CRITICAL  
THRESHOLDS BUT WILL NEED TO MONITOR AS ADDITIONAL WARMING OR  
DEEPER MIXING COULD EVENTUALLY RESULT IN NEAR CRITICAL FIRE  
WEATHER CONDITIONS DEVELOPING OVER THE UPCOMING WEEKEND.  
 

 
   
AVIATION
 
(FOR THE 06Z KGRI/KEAR TAFS THROUGH 06Z SATURDAY)  
ISSUED AT 1227 AM CDT FRI SEP 18 2020  
 
VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD WITH SOME HAZE  
POSSIBLE FROM TIME TO TIME...BUT NO VISIBILITY RESTRICTIONS  
EXPECTED AS THE HEAVIER AREAS OF SMOKE FROM WILDFIRES TO OUR WEST  
ARE EXPECTED TO CONTINUE TO RETREAT WESTWARD. OTHERWISE...EXPECT  
LIGHT SOUTHEASTERLY WINDS THROUGH AROUND MIDDAY...WHICH WILL  
INCREASE TO BETWEEN 12-15KTS BY AFTERNOON AS THE PRESSURE GRADIENT  
TIGHTENS ACROSS THE LOCAL AREA.
