...FLASH FLOODING POSSIBLE IN THE TENNESSEE VALLEY/SOUTHERN
APPALACHIANS SUNDAY/MONDAY...
...HOT TEMPERATURES FOR PORTIONS OF THE NORTHERN PLAINS AND UPPER
MIDWEST; SEVERE THUNDERSTORMS AND HEAVY RAIN POSSIBLE INTO
SUNDAY...
...COOLER THAN NORMAL FOR MUCH OF THE WEST WITH MONSOONAL
THUNDERSTORMS FOR PORTIONS OF THE ROCKIES/SOUTHWEST...
TYPICAL SUMMERTIME PATTERN IS IN FULL SWING ACROSS MUCH OF THE
LOWER 48 THIS WEEKEND INTO EARLY NEXT WEEK. A WEAKENING FRONTAL
BOUNDARY OVER THE SOUTHEAST WILL ACT AS A FOCUS FOR SCATTERED
SHOWERS AND THUNDERSTORMS THIS AFTERNOON/EARLY EVENING AND AGAIN
ON SUNDAY, EVEN AFTER THE BOUNDARY DISSIPATES. THE WARM/MOIST
SOUTHERLY FLOW OUT OF THE GULF OF MEXICO WILL SUPPORT THE CHANCE
FOR FLASH FLOODING OVER THE TENNESSEE VALLEY SUNDAY AND INTO THE
SOUTHERN APPALACHIANS ON MONDAY. HIGH PRESSURE OVER THE EAST COAST
THAT BROUGHT IN A BIT DRIER AIR TO THE REGION WILL SLOWLY MOVE TO
THE COAST BY MONDAY, ALLOWING A SLOW CLIMB OF HUMIDITY VALUES WITH
TYPICAL LATE JULY TEMPERATURES IN THE 80S TO AROUND 90.
TEMPERATURES OVER MUCH OF THE LOWER MS VALLEY INTO COASTAL TEXAS
WILL BE A FEW DEGREES BELOW NORMAL (BUT STILL INTO THE UPPER 80S
TO AROUND 90) THANKS TO MOSTLY CLOUDY SKIES AND HIGH CHANCES OF
RAIN.
IN THE MIDDLE OF THE COUNTRY, HOT TEMPERATURES ARE EXPECTED OVER
THE CENTRAL PLAINS SUNDAY/MONDAY -- UPPER 90S TO LOW 100S. FARTHER
NORTH, A FRONTAL BOUNDARY WILL FAVOR SCATTERED SHOWER AND STORMS
ON SUNDAY, WHERE THE STORM PREDICTION CENTER HAS HIGHLIGHT A
SLIGHT RISK (LEVEL 2/5) FOR SEVERE WEATHER OVER PARTS OF SOUTH
DAKOTA SOUTHWARD THROUGH CENTRAL NEBRASKA. INTO MINNESOTA, LOCALLY
HEAVY RAINFALL COULD RESULT IN AREAS OF FLASH FLOODING ON SUNDAY.
WPC HAS PLACED PORTIONS OF MN IN A SLIGHT RISK (LEVEL 2/4) FOR
EXCESSIVE RAINFALL.
OVER THE WEST, COOLER THAN NORMAL TEMPERATURES WILL CONTINUE FOR
ANOTHER COUPLE OF DAYS OVER AREAS WEST OF THE ROCKIES. STILL,
HIGHS WILL REACH INTO THE 80S TO LOW 90S OVER INTERIOR LOCATIONS
BUT PERHAPS STAY IN THE 60S ALONG THE IMMEDIATE COAST OF NORCAL
NORTHWARD. SMOKE FROM WILDFIRES WILL CONTINUE TO PLAGUE PARTS OF
THE WEST (NORCAL EASTWARD/NORTHEASTWARD INTO MONTANA), RESULTING
IN POOR AIR QUALITY AND AREAS OF REDUCED VISIBILITY. AFFECTED
RESIDENTS ARE URGED TO STAY INDOORS IF POSSIBLE WITH WINDOWS AND
DOORS CLOSED.
