...RECORD HIGH TEMPERATURES TO CONTINUE INTO MID WEEK ACROSS LARGE

BERYL IS EXPECTED TO MOVE STEADILY NORTHEASTWARD FROM CENTRAL  
ARKANSAS TODAY INTO THE LOWER OHIO VALLEY TONIGHT AND INTO THE  
LOWER GREAT LAKES ON WEDNESDAY. WHILE THE WIND SPEEDS ASSOCIATED  
WITH BERYL WILL CONTINUE TO WEAKEN AS IT MOVES FARTHER FROM THE  
GULF OF MEXICO, THE STORM WILL CONTINUE TO BE A PROLIFIC HEAVY  
RAIN PRODUCER AS IT PUSHES NORTHEASTWARD. WIDESPREAD HEAVY RAINS  
AND THUNDERSTORMS ARE LIKELY ALONG AND TO THE NORTHEAST OF THE  
PATH OF BERYL OVER THE NEXT TWO DAYS WITH RAINFALL TOTALS OF 2-5"  
FROM CENTRAL ARKANSAS, ACROSS SOUTHEAST MISSOURI, CENTRAL TO  
SOUTHERN ILLINOIS, INDIANA INTO THE SOUTHERN PORTIONS OF THE L.P.  
OF MICHIGAN AND THEN OVER PORTIONS OF UPSTATE NEW YORK AND  
VERMONT/NEW HAMPSHIRE. THESE AMOUNTS ARE FOLLOWING THE 5 TO 10+  
INCHES OF RAIN THAT FELL ALONG THE PATH OF BERYL AS IT PUSHED  
INLAND EARLIER MONDAY ALONG THE CENTRAL TEXAS GULF COAST. SEVERE  
THUNDERSTORMS CAPABLE OF PRODUCING TORNADOES WILL BE POSSIBLE OVER  
PORTIONS OF THE LOWER OHIO VALLEY TODAY FOLLOWED BY THE INTERIOR  
NORTHEAST ON WEDNESDAY. A HIGHER END SLIGHT RISK (AT LEAST 25%) OF  
EXCESSIVE RAINFALL LEADING TO FLASH FLOODING IS IN EFFECT FOR  
PORTIONS OF UPSTATE NEW YORK INTO VERMONT ON WEDNESDAY. FLOOD  
WATCHES ARE CURRENTLY IN EFFECT ALONG THE PATH OF BERYL FROM  
NORTHERN ARKANSAS, NORTHEASTWARD INTO THE SOUTHEASTERN L.P.  
MICHIGAN, AFFECTING OVER 21 MILLION PEOPLE.  
 
NO LET UP EXPECTED TO THE STRING OF RECORD HIGH TEMPERATURES BEING  
SET ACROSS LARGE PORTIONS OF THE WEST. THE MID TO UPPER-LEVEL HIGH  
THAT HAS BEEN ANCHORING THE RECORD RECORD HEAT IN THE WEST IS NOT  
EXPECTED TO CHANGE MUCH OVER THE NEXT SEVERAL DAYS, AS IT REMAINS  
LOCKED IN PLACE, STRETCHING FROM SOUTHERN CALIFORNIA/DESERT  
SOUTHWEST, NORTHWARD THROUGH THE GREAT BASIN AND ACROSS THE  
PACIFIC NORTHWEST AND NORTHERN ROCKIES. EXCESSIVE HEAT WARNINGS,  
WATCHES, AND HEAT ADVISORIES ARE CURRENTLY IN EFFECT FOR NEARLY  
ALL OF WASHINGTON STATE, OREGON, CALIFORNIA, IDAHO, NEVADA AND  
WESTERN ARIZONA. NUMEROUS RECORD HIGH TEMPERATURES ARE EXPECTED  
ACROSS THESE AREAS OVER THE NEXT FEW DAYS WHERE HIGH TEMPERATURES  
WILL BE ANYWHERE FROM 10 TO AS HIGH AS 30 DEGREES ABOVE AVERAGE.  
IN ADDITION TO THE RECORD HIGH DAILY TEMPERATURES, THE EARLY  
MORNING LOWS ARE ALSO EXPECTED TO SET RECORDS ACROSS LARGE  
PORTIONS OF THE WEST OVER THE COMING TWO MORNINGS. THE MULTI-DAY  
LENGTH AND RECORD WARM OVERNIGHT TEMPERATURES WILL CONTINUE TO  
CAUSE HEAT STRESS TO ANYONE WITHOUT ADEQUATE COOLING AND HYDRATION.  
 
ELSEWHERE, MUCH ABOVE AVERAGE TEMPERATURES ALSO LIKELY TO REMAIN  
IN PLACE ALONG MUCH OF THE EAST OVER THE NEXT FEW DAYS. WHILE  
THERE IS NOT FORECAST TO BE MANY RECORD HIGH TEMPERATURES ACROSS  
THE EAST OVER THE NEXT FEW DAYS, NUMEROUS RECORD HIGH MINIMUM

SOUTHEAST, MID-ATLANTIC AND INTO SOUTHERN NEW ENGLAND. HEAT

SOUTH, SOUTHEAST, MID-ATLANTIC AND SOUTHERN NEW ENGLAND WITH THIS  
LIKELY TO CONTINUE OVER THE NEXT FEW DAYS. AN EXCESSIVE HEAT  
WARNING IS IN EFFECT ACROSS PORTIONS OF SOUTHWESTERN WEST VIRGINIA  
FOR THIS AFTERNOON DUE TO THE COMBINATION OF HOT TEMPERATURES AND  
HIGH HUMIDITY CREATE A DANGEROUS SITUATION IN WHICH HEAT RELATED  
ILLNESSES ARE LIKELY.
