...EXCESSIVE RAINFALL AND SEVERE WEATHER THREATEN PORTIONS OF THE
MISSISSIPPI VALLEY AND SOUTHERN PLAINS TODAY...
...INCREASING EXCESSIVE HEAT RISK POTENTIAL OVER PARTS OF THE WEST
AND SOUTHERN TEXAS THROUGH MID-WEEK...
SHORTWAVE ENERGY SPINNING THROUGH THE NORTHWEST WILL SUPPORT
SHOWERS AND THUNDERSTORM ACTIVITY ACROSS THE REGION TODAY.
RAINFALL RATES OVER THE FAVORED TERRAIN OF THE CASCADES AND
NORTHERN ROCKIES WILL BE HIGH ENOUGH TO WARRANT AN EXCESSIVE
RAINFALL THREAT. THUS, A SLIGHT RISK (AT LEAST 15%) OF EXCESSIVE
RAINFALL LEADING TO FLASH FLOODING IS IN EFFECT FOR PORTIONS OF
THE NORTHERN ROCKIES, WHILE A MARGINAL RISK (AT LEAST 5%) AREA IS
IN PLACE OVER THE CASCADES, OLYMPICS AND SEATTLE METRO AREA.
ELSEWHERE, SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE OVER
PARTS OF THE GREAT PLAINS AND MISSISSIPPI VALLEY TODAY. POCKETS OF
SEVERE THUNDERSTORMS CAPABLE OF PRODUCING HEAVY TO EXCESSIVE
RAINFALL MAY DEVELOP OVER PARTS OF THE SOUTHERN PLAINS INTO THE
MISSISSIPPI VALLEY. SLIGHT RISKS OF EXCESSIVE RAINFALL AND SEVERE
THUNDERSTORMS ARE IN EFFECT OVER THOSE AREAS, WHERE A SWATH OF
DAMAGING WIND GUSTS ARE POSSIBLE. THE SEVERE THUNDERSTORM THREAT
CONCENTRATES OVER PARTS OF THE CENTRAL PLAINS AND MIDDLE
MISSISSIPPI VALLEY ON TUESDAY, WHERE A SLIGHT RISK IS IN EFFECT.
LARGE HAIL IS POSSIBLE AT THE OUTSET WHEN STORMS ARE MORE
CELLULAR, BUT WILL THEN BE FOLLOWED BY A CONGEALING OF CELLS INTO
A LINE OF STORMS WITH DAMAGING WIND GUSTS EVENTUALLY BEING THE
MAIN THREAT.
AN UPPER RIDGE IS EXPECTED TO DEVELOP OVER THE WEST EARLY TO
MID-WEEK. HIGH TEMPERATURES WILL GRADUALLY CLIMB INTO 100S BY
WEDNESDAY AND THURSDAY WITH MANY RECORDS POTENTIALLY BEING TIED OR
BROKEN ON THOSE DAYS. EXCESSIVE HEAT WARNINGS ARE IN EFFECT FOR
THE CENTRAL VALLEY REGION OF CALIFORNIA WHILE EXCESSIVE HEAT
WATCHES ARE IN EFFECT FOR PARTS OF THE DESERT SOUTHWEST. EXTREME
HEATRISK IS PROBABLE TO CONTINUE FOR MUCH OF SOUTHERN TEXAS
THROUGH WEDNESDAY. THIS LEVEL OF HEAT RISK MEANS THAT THERE WILL
LIKELY BE LITTLE TO NO OVERNIGHT RELIEF FOR THOSE WITHOUT
EFFECTIVE COOLING AND/OR ADEQUATE HYDRATION.
