NATIONAL WEATHER SERVICE SALT LAKE CITY UT  
1023 AM MDT TUE JUL 7 2020  
   
SYNOPSIS
 
A WARM AND DRY WEST SOUTHWEST FLOW ALOFT WILL PREVAIL  
THROUGH MUCH OF THE WEEK. FIRE WEATHER ISSUES DUE TO LOW HUMIDITY  
AND GUSTY WINDS WILL BE A CONCERN THROUGH AT LEAST MIDWEEK.  
 

 
   
DISCUSSION
 
AS OF 10 AM MDT THE SLC AIRPORT IS CLOSING IN ON  
90F. WE'RE LOOKING TO ONCE AGAIN TOP OUT IN THE UPPER 90S ALONG  
THE WASATCH FRONT AND CLOSE TO 105 DOWN SOUTH IN THE ST GEORGE  
AREA. THE CHALLENGE THIS MORNING IS TO FIND ANY SPECK OF CLOUDS IN  
THE STATE, AND AS OF THIS WRITING THERE MAY BE A FEW INDIVIDUAL  
CLOUDS IN THE RAFT RIVER MOUNTAINS ALONG THE IDAHO BORDER BUT  
THOSE SHOULD BE FLEETING AT BEST.  
 
NO CHANGES TO THE FORECAST THIS MORNING. WE'RE STILL ON TRACK FOR  
OUR GOING RED FLAG HEADLINES TODAY AND TOMORROW WITH THE SURFACE  
BOUNDARY PUSHING THROUGH NORTHERN UTAH THIS MORNING AND GUSTY  
SOUTH WINDS ALREADY EVIDENT ACROSS CENTRAL AND SOUTHERN UTAH.  
 
TEMPERATURES WILL SEE A BRIEF RESPITE WEDNESDAY WITH A PASSING  
TROUGH THROUGH THE NORTHERN ROCKIES TO HELP SUPPRESS THE RIDGE A  
BIT FARTHER SOUTH. THURSDAY AND BEYOND INTO THE WEEKEND THE RIDGE  
WILL STRENGTHEN AND ALLOW TEMPERATURES TO CONTINUE TO RISE ACROSS  
THE AREA.  
 

 
   
AVIATION
 
WINDS AT THE KSLC TERMINAL HAVE SHIFTED TO THE  
NORTHWEST AND SHOULD PERSIST INTO AT LEAST THE EVENING HOURS.  
WINDS WILL BE MODERATELY GUSTY AT TIMES THIS AFTERNOON. VFR  
CONDITIONS ARE EXPECTED TO PREVAIL OVER THE AIRFIELD.  
 

 
   
FIRE WEATHER...(ISSUED 343 AM MDT)
 
 
HIGH PRESSURE ALOFT CENTERED TO THE SOUTH OF UTAH AND A SERIES OF  
WEATHER DISTURBANCES MOVING EAST THROUGH THE PACIFIC  
NORTHWEST/NORTHERN ROCKIES WILL LEAVE THE AREA UNDER A DRY AND  
SEASONALLY WARM WEST-SOUTHWEST THROUGH THE UPCOMING WEEKEND.  
 
THE DISTURBANCE MOVING THROUGH THE NORTHERN ROCKIES TODAY WILL NUDGE  
A SHALLOW, DRY COLD FRONT THROUGH THE NORTHERN HALF OF THE STATE.  
THIS FRONT WILL BRING SLIGHTLY COOLER, MORE SEASONAL TEMPERATURES  
TO THE NORTH, WITH CONTINUED WINDY, HOT AND VERY DRY CONDITIONS  
AHEAD OF THE FRONT OVER THE SOUTHERN HALF OF THE STATE.  
 
CONTINUED HOT AND WINDY CONDITIONS ACROSS FAR SOUTHERN THROUGH  
EAST-CENTRAL UTAH WEDNESDAY WILL BRING A RENEWED THREAT OF CRITICAL  
FIRE WEATHER CONDITIONS. HOT AND DRY CONDITIONS WILL PERSIST LATE IN  
THE WEEK THROUGH THE WEEKEND WITH POOR RH RECOVERIES ACROSS MUCH  
OF SOUTHERN AND EAST-CENTRAL UTAH. CRITICAL FIRE WEATHER CONDITIONS  
LOOK TO BE MORE ISOLATED LATE IN THE WEEK AS WINDS GENERALLY REMAIN  
A LITTLE BELOW CRITERIA.
