HEAVY RAIN THAT MAY CAUSE SOME FLOODING ISSUES. DRY CONDITIONS ARE  
EXPECTED TO CONTINUE FOR MOST OF THE WESTERN U.S. FROM THE ROCKIES  
WESTWARD.  
 
MUCH OVER THE CENTRAL AND EASTERN U.S. WILL CONTINUE TO HAVE A  
HEAT WAVE AS AN UPPER LEVEL RIDGE STRENGTHENS. MOSTLY SUNNY SKIES  
AND HOT CONDITIONS CAN BE EXPECTED INTO THE MIDDLE OF THE WEEK.

TO NEW ENGLAND. NUMEROUS HEAT ADVISORIES AND EXCESSIVE HEAT  
WARNINGS ARE IN EFFECT FROM NEAR MEMPHIS TO MICHIGAN, AND ALSO FOR  
THE MID-ATLANTIC TO NORTHERN NEW ENGLAND. HIGH TEMPERATURES IN
