DISCUSSION
 
TODAY THROUGH MONDAY.  
 
AN EXTENDED PERIOD OF DRY, BREEZY WEATHER IS EXPECTED THROUGH THE  
END OF THE WEEK UNDER A PREVAILING SOUTHWESTERLY FLOW PATTERN. A  
SHORTWAVE TROUGH WILL SWING ACROSS THE WESTERN U.S. TODAY  
RESULTING IN WIDESPREAD, SOUTHWESTERLY WIND GUSTS OF 30 TO 40 MPH  
THIS AFTERNOON AND EARLY EVENING. WITH VERY DRY AIR IN PLACE AND  
FIRE FUELS AT CRITICAL LEVELS, THESE WINDS COULD LEAD TO RAPID  
FIRE GROWTH IF IGNITED AND THE RED FLAG WARNING REMAINS IN PLACE  
TODAY FOR LINCOLN, MOHAVE, AND PORTIONS OF CLARK COUNTIES. WINDS  
OF THIS MAGNITUDE WILL CONTINUE ON WEDNESDAY BUT BECOME MORE  
FOCUSED ACROSS MOHAVE COUNTY AND FAR EASTERN CLARK COUNTY WHERE  
THE RED FLAG WARNING EXTENSION HAS BEEN ISSUED. WAVES OF 1 TO 2  
FEET WILL ALSO BE A RESULT OF THE ENHANCED WINDS ON PORTIONS OF  
AREA LAKES, CREATING NONIDEAL BOATING CONDITIONS. TODAY WILL BE  
THE LAST DAY OF ABOVE NORMAL TEMPS FOR THE AREA BEFORE HEIGHT  
FALLS ALLOW TEMPS TO DROP A FEW DEGREES TO NEAR NORMAL VALUES FOR  
MID-JULY ON WEDNESDAY.  
 
THE SECOND HALF OF THE WEEK WILL BE CHARACTERIZED BY CONTINUED  
BREEZY CONDITIONS, GUSTING IN THE 20 TO 25 MPH RANGE EACH AFTERNOON,  
AND NEAR NORMAL TEMPERATURES AS A BROAD-SCALE TROUGH REMAINS  
SITUATED OVER THE GREAT BASIN THROUGH SATURDAY. THE HIGH WILL  
BEGIN TO BUILD BACK NORTHWARD TOWARDS THE FOUR CORNERS REGION LATE  
THIS WEEKEND INTO EARLY NEXT WEEK LEADING TO A POTENTIAL SHIFT TO  
A WETTER WEATHER PATTERN.

A DRY WEATHER SYSTEM WILL PASS ACROSS THE REGION TODAY INCREASING  
SOUTHWESTERLY WINDS ACROSS MUCH OF THE AREA TO 20 TO 30 MPH GUSTING
