THE UPPER LEVEL RIDGE IS STARTING TO BUILD OVER THE EASTERN HALF
OF THE US AND THAT WILL BRING A PROLONGED PERIOD OF HOT WEATHER.
HIGHS ARE ALREADY WELL INTO THE 90S AND WE WILL SEE THAT CONTINUE
THIS WEEK AS THE RIDGE REMAINS OVERHEAD. WEDNESDAY AND THURSDAY
LOOK TO BE THE PEAK OF THE HEAT WITH HIGHS PUSHING INTO THE MID TO
UPPER 90S AND UP TO A 40% CHANCE OF 100+ FOR PARTS OF THE AREA.
ONCE YOU ADD IN HUMIDITY WITH DEW POINTS IN THE 70S WE WILL SEE
AFTERNOON HEAT INDEX VALUES PUSH INTO THE TRIPLE DIGITS AND WILL
BE AS HOT AS 109 WEDNESDAY AND THURSDAY. THIS HEAT WILL BRING
MAJOR TO EXTREME HEAT RISK BY THE MIDDLE OF THE WEEK. OVERNIGHT
LOWS ARE ALSO GOING TO REMAIN MILD ONLY FALLING INTO THE 70S. WITH
THE RIDGE OVERHEAD RAIN CHANCES WILL BE NEAR ZERO BUT AFTERNOON
CUMULUS CLOUDS CAN BE EXPECTED.

WEEK AS AN UPPER LEVEL TROUGH PUSHES INTO THE NORTHEAST. THIS WILL
START TO BRING A GRADUAL COOLDOWN FRIDAY INTO THE WEEKEND. IT WILL
STILL BE ON THE HOT SIDE OVER THE HOLIDAY WEEKEND BUT HIGHS
SHOULD FALL BACK INTO THE LOW TO MID 90S. HIGHS WILL CONTINUE TO
COOL INTO EARLY NEXT WEEK INTO THE UPPER 80S TO LOWER 90S WHICH IS
GETTING A LITTLE CLOSER TO SEASONAL NORMS. AS THE RIDGE BREAKS
