PORTIONS OF THE MID-ATLANTIC AND NORTHEAST.  
 
STRONG, POSSIBLY SEVERE, SHOWERS AND THUNDERSTORMS WILL FIRE

MISSISSIPPI VALLEY - THE STORM PREDICTION CENTER HAS IDENTIFIED  
THIS REGION AS HAVING A SLIGHT RISK FOR SEVERE WEATHER.  
ADDITIONALLY, SOME OF THESE STORMS MAY PRODUCE HEAVY RAIN OVER  
PORTIONS OF NEBRASKA AND KANSAS.  
 
MUCH OF THE THE WESTERN STATES WILL CONTINUE TO BE HOT AND MOSTLY  
DRY OVER THE NEXT FEW DAYS, ALTHOUGH TEMPERATURES WILL BE STEADILY  
MODERATING THIS WEEKEND. LOW HUMIDITY ALONG WITH GUSTY WINDS WILL  
MAINTAIN AN ELEVATED THREAT FOR THE SPREAD OF WILDFIRES ACROSS  
PORTIONS OF CALIFORNIA, THE INTERMOUNTAIN WEST AND THE NORTHERN

IN EFFECT FOR THESE REGIONS. ADDITIONALLY, SEVERAL LOCATIONS
