...ADDITIONAL ROUNDS OF SEVERE WEATHER WITH HEAVY RAINFALL AND
FLASH FLOODING CHANCES PERSIST ACROSS THE CENTRAL PLAINS THROUGH
LATE WEEK, REACHING INTO THE MISSISSIPPI VALLEY BY SATURDAY...
...HOT WEATHER CONTINUES OVER THE INTERIOR NORTHWEST AND PARTS OF
THE EAST WHILE EXCESSIVE HEAT WARNINGS AND CRITICAL FIRE RISK
REMAIN IN EFFECT FOR ARIZONA...
A FRONTAL SYSTEM OR TWO STRETCHED ACROSS THE PLAINS WILL HELP
CAUSE REPEATING ROUNDS OF CONVECTION AS IT FOCUSES MOISTURE AND
INSTABILITY. SEVERE WEATHER AND HEAVY RAINFALL POTENTIALLY CAUSING
FLASH FLOODING ARE LIKELY THROUGH THE END OF THE WEEK WITH
MULTIPLE CONVECTIVE STORMS AND COMPLEXES. MORE SPECIFICALLY,
THROUGH THE REST OF THE DAY AND TONIGHT, SLIGHT TO ENHANCED RISKS
OF SEVERE WEATHER ARE IN PLACE ACROSS MUCH OF THE HIGH PLAINS AS
TORNADOES, HIGH WINDS, AND LARGE HAIL ARE ALL THREATS. FLASH
FLOODING IS POSSIBLE AS WELL IN THE CENTRAL PLAINS AND DOWNSTREAM
INTO THE LOWER MISSISSIPPI VALLEY. NOT MUCH WILL CHANGE
METEOROLOGICALLY FOR FRIDAY, WITH SLIGHT RISKS OF BOTH SEVERE
WEATHER AND FLASH FLOODING IN PLACE AGAIN FOR THE SOUTH-CENTRAL
PLAINS. FOR FRIDAY NIGHT INTO SATURDAY, THESE RISKS COULD STRETCH
FARTHER EAST INTO THE MIDDLE AND LOWER MISSISSIPPI VALLEY AS THE
SURFACE FRONTS AND WAVES OF LOW PRESSURE START TO CONSOLIDATE.
SCATTERED SHOWERS AND THUNDERSTORMS ARE ALSO EXPECTED ACROSS THE
EAST. AMPLE MOISTURE AHEAD OF A COLD FRONT TRACKING SLOWLY
EASTWARD COULD LEAD TO STORMS IN THE INTERIOR NORTHEAST AND
MID-ATLANTIC THAT MAY CAUSE FLASH FLOODING PARTICULARLY TOMORROW
AFTERNOON, AS INDICATED BY A SLIGHT RISK OF EXCESSIVE RAINFALL.
SUMMERTIME SCATTERED THUNDERSTORMS SHOULD LINGER ACROSS THE
SOUTHERN TIER STATES AS WELL.
COOL TEMPERATURES ACROSS THE NORTHERN/CENTRAL PLAINS WILL PERSIST
INTO THE WEEKEND AT LEAST, WHILE GRADUALLY MODERATING AND
SPREADING EAST. MEANWHILE, TEMPERATURES SHOULD BE NEAR TO ABOVE
AVERAGE SOUTH OF THE FRONT FROM THE DESERT SOUTHWEST ACROSS THE
SOUTH AND INTO THE EAST. SOUTHWESTERN STATES CAN EXPECT
TEMPERATURES WELL INTO THE 100S AND EVEN 110S, WITH EXCESSIVE HEAT
WARNINGS IN EFFECT THROUGH FRIDAY IN SOUTHERN ARIZONA. DRY AND
WINDY CONDITIONS COMBINED WITH THE HEAT WILL LEAD TO CRITICAL FIRE
WEATHER RISKS OVER THE NEXT COUPLE OF DAYS ACROSS NORTHERN
ARIZONA. ADDITIONALLY, HIGH TEMPERATURES IN THE MID-90S ACROSS
SOUTHERN FLORIDA COULD CHALLENGE DAILY RECORDS DURING THE NEXT
COUPLE OF DAYS. HEAT ADVISORIES REMAIN IN PLACE THERE AND ALSO IN
PARTS OF THE NORTHEAST GIVEN WARM TEMPERATURES THROUGH THIS
EVENING. ON THE OPPOSITE SIDE OF THE COUNTRY, HOT WEATHER IS
FORECAST TO CONTINUE OVER PARTS OF THE NORTHWEST WHERE HIGH
TEMPERATURES NEARING 100F ARE FORECAST FOR THE NEXT FEW DAYS AT
THE HOTTEST LOCATIONS ACROSS THE INTERIOR SECTIONS. AFTER A WARM
AFTERNOON/EVENING TODAY IN THE PACIFIC NORTHWEST, TEMPERATURES
ACROSS THOSE REGIONS CLOSER TO THE COAST SHOULD GRADUALLY MODERATE
LATE WEEK.
