SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS WILL SET UP  
ACROSS THE CENTRAL/SOUTHERN ROCKIES, MID-MISSISSIPPI VALLEY AND  
THE GREAT LAKES REGION AS A COLD FRONT PUSHES SOUTH AND EAST OVER  
THE NEXT COUPLE OF DAYS. THE SOUTHERN EXTENT OF THE FRONT WILL  
STALL OVER MUCH OF THE CENTRAL/SOUTHERN PLAINS AND MID-MISSISSIPPI  
VALLEY AND WILL PROVIDE A FOCUS FOR STRONG/SEVERE THUNDERSTORMS  
THAT ARE SLOW MOVING STORMS; WHICH WILL INCREASE THE RISK FOR  
HEAVY RAINFALL AND FLASH FLOODING. WPC HAS PORTIONS OF THIS  
CORRIDOR IN A SLIGHT RISK FOR EXCESSIVE RAINFALL THROUGH WEDNESDAY  
MORNING, AS WELL AS, SPC HIGHLIGHTING A SLIGHT RISK FOR SEVERE  
WEATHER.

ELEVATED RISK FOR FIRE DANGER. SMOKE FROM ONGOING WILDFIRES  
CONTINUE TO DEGRADE AIR QUALITY- AIR QUALITY ALERTS REMAIN IN  
EFFECT FOR PORTIONS OF THE WESTERN AND SOUTHWESTERN U.S.  
TEMPERATURES ARE EXPECTED TO CLIMB AS A STRONG RIDGE BUILDS BACK  
ACROSS THE SOUTHWEST AND WEST OVER THE COMING DAYS. EXCESSIVE HEAT  
WATCHES AND WARNINGS ARE IN EFFECT ACROSS LARGE PORTIONS SOUTHERN  
CALIFORNIA, SOUTHERN NEVADA, WESTERN AND SOUTHERN ARIZONA, AS WELL  
AS, PORTIONS OF INTERIOR WASHINGTON AND OREGON AS AFTERNOON HIGHS  
REACH OR EXCEED 100 DEGREES.  
 
STRONG SOUTHERLY FLOW WILL PUMP HOT AND HUMID AIR INTO THE  
NORTHEAST, RESULTING IN ABOVE NORMAL TEMPERATURES AND EVEN HIGHER  
INDEX VALUES. HEAT ADVISORIES ARE IN EFFECT ACROSS MUCH OF THE  
NORTHEAST THROUGH TUESDAY. A COLD FRONT WILL PASS THROUGH AFTER  
THIS POINT AND HELP TO COOL THINGS DOWN. IN THE MEANTIME, SEVERAL  
AREAS IN THE NORTHEAST ALSO HAVE POOR AIR QUALITY.
