...THREATS FOR SEVERE WEATHER AND FLASH FLOODING FOR PORTIONS OF
THE CENTRAL PLAINS INTO THE MIDDLE/LOWER MISSOURI RIVER VALLEY
THROUGH SATURDAY...
...EXCESSIVE HEAT OVER THE WEST AND SOUTHWEST THROUGH SATURDAY BUT
SOME RELIEF COMING ON SUNDAY...
MOST OF THE ACTIVE WEATHER ACROSS THE LOWER 48 WILL FOCUS ACROSS
THE CENTRAL PORTION OF THE NATION THROUGH THE WEEKEND IN THE FORM
OF SEVERE THUNDERSTORMS AND POTENTIAL FOR FLASH FLOODING.
ANOMALOUS MOISTURE WILL POOL IN THE VICINITY OF A PAIR OF FRONTAL
BOUNDARIES LOCATED OVER THE CENTRAL PLAINS THIS EVENING. SEVERE
THUNDERSTORMS ARE EXPECTED TO INCREASE IN COVERAGE THROUGH THIS
EVENING NEAR A STATIONARY FRONT CURRENTLY IN PLACE ACROSS
NEBRASKA, WITH THREATS FOR LARGE HAIL AND DAMAGING STRAIGHT LINE
WINDS IN ADDITION TO TORNADOES. AN ORGANIZED THUNDERSTORM COMPLEX
IS LIKELY TO FORM TONIGHT AND TRANSLATE TOWARD THE SOUTHEAST
TOWARD THE LOWER MISSOURI VALLEY, CARRYING A RISK FOR FLASH
FLOODING WITH HIGH RAINFALL RATES AND POSSIBLY 4-5 INCHES OF RAIN
BY SATURDAY MORNING.
SEVERE WEATHER (MAINLY HAIL AND WIND) AND FLASH FLOOD POTENTIAL
WILL FOCUS A LITTLE FARTHER SOUTH ON SATURDAY AS A COLD FRONT
MOVES THROUGH THE CENTRAL PLAINS. THE THREAT REGION WILL EXTEND
FROM THE CENTRAL HIGH PLAINS, THROUGH SOUTHERN KS INTO THE MIDDLE
MISSISSIPPI AND LOWER OHIO VALLEYS. SPOTTY RAINFALL TOTALS IN
EXCESS OF 3 INCHES WILL BE POSSIBLE IN ADDITION TO THE SEVERE
THUNDERSTORMS.
OUT WEST, AN UPPER LEVEL RIDGE IN PLACE OVER THE WESTERN U.S. WILL
MAINTAIN THE HOT WEATHER ON SATURDAY THAT HAS BEEN IMPACTING THE
REGION OVER THE PAST COUPLE OF DAYS. HOWEVER, THE UPPER LEVEL
RIDGE WILL BE DISPLACED AND WEAKENED WITH THE APPROACH OF AN
UPSTREAM TROUGH AXIS AND ASSOCIATED SURFACE COLD FRONT. THE COLD
FRONT IS FORECAST TO ARRIVE EARLY ON SUNDAY AND ADVANCE SOUTH AND
EAST DURING THE DAY WHICH WILL LOWER THE MAGNITUDE OF HOT WEATHER.
TEMPERATURES HOWEVER, ARE STILL LIKELY TO REMAIN UP TO ROUGHLY 10
DEGREES ABOVE AVERAGE ON SUNDAY.
ACROSS THE GREAT LAKES REGION INTO THE NORTHEAST, TEMPERATURES
WILL RUN 5 TO 15 DEGREES BELOW AVERAGE BENEATH THE INFLUENCE OF
UPPER LEVEL TROUGHING THIS WEEKEND. THE REGION WILL REMAIN
UNSETTLED HOWEVER, WITH MULTIPLE ROUNDS OF SHOWERS AND
THUNDERSTORMS BENEATH THE UPPER TROUGH AND WITH A SURFACE LOW/COLD
FRONT TRACKING EASTWARD THROUGH SUNDAY. EAST OF THE APPALACHIANS,
FROM THE MID-ATLANTIC TO SOUTHEAST, HIGH PRESSURE WILL KEEP
TEMPERATURES NEAR TO SLIGHTLY ABOVE AVERAGE FOR THE WEEKEND BUT
WITH LITTLE TO NO CHANCES FOR PRECIPITATION. THE ONE EXCEPTION
WILL BE ACROSS THE FLORIDA PENINSULA WHERE HIGH TEMPERATURES IN
THE MIDDLE TO UPPER 90S MAY CHALLENGE A FEW DAILY MAXIMUM
TEMPERATURE RECORDS ON SATURDAY AND SUNDAY. IN ADDITION, DIURNALLY
DRIVEN THUNDERSTORMS ARE EXPECTED EACH DAY BUT WITH A FOCUS ACROSS
SOUTHERN FLORIDA WHERE ACCESS TO BETTER MOISTURE WILL RESIDE.
