...A HEAT WAVE CONTINUES FROM THE MIDWEST TO THE MID-ATLANTIC AND  
NORTHEAST THROUGH THE 4TH OF JULY HOLIDAY...  
 
...WET SNOW IS POSSIBLE OVER THE HIGH ELEVATIONS OF THE NORTHERN  
CASCADES AND NORTHWEST MONTANA...  
 
HOT AN HUMID WEATHER WILL CONTINUE TO BE THE STORY ACROSS A LARGE  
PORTION OF THE COUNTRY FROM THE CENTRAL PLAINS NORTHEASTWARD INTO  
THE MID-ATLANTIC AND NEW ENGLAND AS WE HEAD INTO THE 4TH OF JULY  
HOLIDAY. UNDER THE INFLUENCE OF A STRONG SUBTROPICAL HIGH  
PRESSURE SYSTEM, TEMPERATURES WILL REMAIN MORE THAN 10 DEGREES  
ABOVE NORMAL ACROSS NEW ENGLAND. A WEAK COLD FRONT WILL OFFER  
ONLY SLIGHT RELIEF FROM THE HEAT ACROSS THE GREAT LAKES FOLLOWED  
BY NEW ENGLAND ON TUESDAY. BUT THE STRONG JULY SUN WILL  
PRACTICALLY ERASE THE SLIGHT COOLING AND RETURN CONDITIONS TO HOT  
AND HUMID ON INDEPENDENCE DAY. ALONG THE GULF COAST REGION, A  
WEAK LOW PRESSURE SYSTEM INTERACTING WITH TROPICAL MOISTURE IS  
FORECAST TO MOVE GENERALLY WESTWARD FOR THE NEXT COUPLE OF DAYS,  
BRINGING THUNDERSTORMS WITH LOCALLY HEAVY DOWNPOURS ALONG THE  
LOUISIANA COAST TONIGHT AND INTO THE TEXAS COAST ON WEDNESDAY.  
FARTHER MOISTURE FROM THE WESTERN ATLANTIC ASSOCIATED WITH AN  
INVERTED TROUGH IS FORECAST TO REACH THE SOUTHEAST U.S. COAST ON  
WEDNESDAY.  
 
MEANWHILE, A DEEP UPPER-LEVEL TROUGH HAS BEEN BRINGING MUCH COOLER  
THAN NORMAL TEMPERATURES INTO THE PACIFIC NORTHWEST. IN FACT, WET  
SNOW IS IN THE FORECAST OVER THE HIGH ELEVATIONS OF THE NORTHERN  
CASCADES AND NORTHWEST MONTANA TONIGHT. OVER THE NORTHERN PLAINS,  
SHOWERS AND THUNDERSTORMS CAN BE EXPECTED TO FORM AS THE DEEP  
UPPER-LEVEL TROUGH APPROACHES DURING THE NEXT COUPLE OF DAYS.
