...STRONG COLD FRONT FOR THE EAST COAST AND QUIET WEATHER  
CONDITIONS FOR MUCH OF THE CENTRAL AND WESTERN STATES...  
 
A STRONG AUTUMN STORM SYSTEM IS SLOWLY TRACKING ACROSS THE GREAT  
LAKES AND WILL LIFT NORTHEASTWARD INTO CANADA BY WEDNESDAY. A  
STRONG COLD FRONT EXTENDS SOUTHWARD FROM THIS LOW, AND WILL BRING  
A SWATH OF MODERATE TO HEAVY RAIN ALONG WITH EMBEDDED  
THUNDERSTORMS FROM THE MID-ATLANTIC TO THE NORTHEAST U.S. THE  
HEAVIEST RAINFALL IS LIKELY TO MATERIALIZE ACROSS NEW ENGLAND AS  
DEEP MOISTURE AHEAD OF THE FRONT LEADS TO 1 TO 3 INCH RAINFALL  
AMOUNTS, WITH ISOLATED HIGHER TOTALS POSSIBLE. SOME INSTANCES OF  
FLASH FLOODING WILL BE POSSIBLE GIVEN THE ATMOSPHERIC SET-UP.  
COOLER AND DRIER CONDITIONS WILL MAKE IT FEEL LIKE FALL AGAIN  
BEHIND THE FRONT.  
 
ELSEWHERE ACROSS THE CONTINENTAL U.S., FIRE WEATHER CONCERNS WILL  
CONTINUE ACROSS PARTS OF CALIFORNIA THROUGH THE MIDDLE OF THE WEEK  
WITH VERY DRY CONDITIONS AND GUSTY WINDS EXPECTED. A BIG HEAT  
WAVE IS ALSO IN THE FORECAST FOR SOUTHERN CALIFORNIA, WITH  
WIDESPREAD 90S AND 100S EXPECTED THROUGH WEDNESDAY WITH EXCESSIVE  
HEAT WARNINGS IN EFFECT. COOL AND DRY CONDITIONS WILL PREVAIL  
ACROSS THE PLAINS AND THE INTERMOUNTAIN WEST WITH NO MAJOR WEATHER  
SYSTEMS TO PRODUCE PRECIPITATION.
