...EXCESSIVE RAINFALL AND SEVERE THUNDERSTORMS POSSIBLE OVER
PORTIONS OF THE GREAT PLAINS AND MISSISSIPPI VALLEY...
...HEAVY TO EXCESSIVE RAINFALL POSSIBLE ACROSS PARTS OF THE
NORTHWEST THROUGH MONDAY...
...INCREASING EXCESSIVE HEAT THREAT OVER PARTS OF CALIFORNIA,
NEVADA AND ARIZONA...
A SERIES OF SHORTWAVES WILL BE RESPONSIBLE FOR EXCESSIVE RAINFALL
AND SEVERE THUNDERSTORMS THAT DEVELOP ACROSS THE GREAT PLAINS AND
MISSISSIPPI VALLEY OVER THE NEXT FEW DAYS. TODAY, SHOWERS AND
ISOLATED THUNDERSTORMS WILL SPREAD FROM THE HIGH PLAINS INTO THE
MISSISSIPPI VALLEY. SOME STORMS MAY TURN SEVERE. THE STORM
PREDICTION CENTER ISSUED AN ENHANCED RISK (LEVEL 3/5) OF SEVERE
THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL HIGH PLAINS THIS
AFTERNOON AND EVENING. VERY LARGE HAIL, SEVERE WIND GUSTS GREATER
THAN 75 MPH, AND A FEW TORNADOES ARE EXPECTED. RAIN RATES IN SOME
OF THOSE STORMS COULD BE HIGH ENOUGH TO CAUSE FLASH FLOODING WHICH
IS WHY THERE'S A SLIGHT RISK (AT LEAST 15%) OF EXCESSIVE RAINFALL
OVER PARTS OF THE NORTHERN/CENTRAL PLAINS AND UPPER/MIDDLE
MISSISSIPPI VALLEY.
ELSEWHERE, A DEEP UPPER LOW WILL TRANSPORT ANOMALOUS TROPICAL
PACIFIC MOISTURE INTO THE NORTHWEST TODAY. EXCESSIVE RAINFALL IS
NATURALLY A CONCERN OVER THE FAVORABLE TERRAIN OF THE CASCADES,
BITTERRROOTS, SALMON RIVER MOUNTAINS AS WELL AS THE SEATTLE METRO,
WHERE SLIGHT RISKS (AT LEAST 15%) ARE IN EFFECT THROUGH MONDAY.
MONDAY WILL BE A MARGINAL RISK KIND OF DAY FOR EXCESSIVE RAINFALL
AND SEVERE THUNDERSTORMS OVER PARTS OF THE SOUTHERN/CENTRAL PLAINS
AND MISSISSIPPI VALLEY. CLOUDY/COOLER CONDITIONS WILL PREVAIL OVER
THE NORTHWEST THANKS TO THE ATMOSPHERIC RIVER EVENT SET TO UNFOLD
OVER THE NEXT COUPLE OF DAYS. OTHERWISE, THE GREAT PLAINS AND
NORTHEAST ARE LIKELY TO EXPERIENCE ABOVE AVERAGE TEMPERATURES THIS
WEEK. ABNORMAL HEAT IS EXPECTED TO EXPAND ACROSS PARTS OF THE WEST
MID-WEEK.
