...STALLED FRONTAL BOUNDARY TO PRODUCE HEAVY RAINFALL CHANCES
ACROSS PORTIONS OF THE MID-ATLANTIC THROUGH FRIDAY...
...DANGEROUS AND RECORD-BREAKING HEAT TO CONTINUE FOR MUCH OF THE
WEST THROUGH THE END OF THE WORK WEEK, WHILE SIZZLING TEMPERATURES
ALSO BEGIN TO BUILD ACROSS THE CENTRAL PLAINS AND SOUTHEAST...
A FRONTAL BOUNDARY STALLING ALONG THE EAST COAST TODAY AND A
DEVELOPING AREA OF LOW PRESSURE ACROSS THE SOUTHEAST WILL HELP
FUEL SCATTERED SHOWERS AND THUNDERSTORMS FOR MUCH OF THE EASTERN
U.S. INTO EARLY THIS WEEKEND. THE MAIN WEATHER HAZARD ASSOCIATED
WITH THESE STORMS ARE EXPECTED TO BE RELATED TO HEAVY RAINFALL.
INTENSE RAIN RATES ARE MOST LIKELY ACROSS PORTIONS OF THE EASTERN
MID-ATLANTIC THROUGH FRIDAY, WHERE A SLIGHT RISK (LEVEL 2/4) OF
EXCESSIVE RAINFALL IS IN EFFECT. ISOLATED SHOWERS AND STORMS ARE
ALSO ANTICIPATED FROM THE CENTRAL/SOUTHERN FLORIDA PENINSULA TO
SOUTHERN NEW ENGLAND, WHERE THE FLASH FLOODING THREAT IS MORE
LOCALIZED UNTIL THE HIGHEST RAINFALL CHANCES BEGIN TO DIMINISH ON
SATURDAY. REMAIN WEATHER AWARE IF TRAVELING OR RESIDING IN FLOOD
PRONE REGIONS AND ALWAYS REMEMBER TO NEVER DRIVE THROUGH FLOODED
ROADWAYS.
RECORD-BREAKING HEAT IS SET TO CONTINUE FOR LARGE SECTIONS OF THE
COUNTRY INTO THIS WEEKEND, WHILE ALSO REBUILDING THROUGHOUT OTHER
AREAS. HIGHS ON FRIDAY AND SATURDAY ARE FORECAST TO REACH INTO THE
UPPER 90S AND TRIPLE DIGITS FROM THE SOUTHWEST TO GREAT PLAINS,
WHICH COULD ALSO REACH INTO DAILY RECORD TERRITORY. THERMOMETERS
SOARING INTO THE 110S AND 120S ARE EXPECTED IN THE DESERT
SOUTHWEST AND TYPICAL INTERIOR VALLEY HOT SPOTS. WIDESPREAD
EXCESSIVE HEAT WARNINGS AND HEAT ADVISORIES ARE IN EFFECT FOR THE
WEST (OUTSIDE OF PARTS OF THE NORTHWEST), AS WELL AS SCATTERED
THROUGHOUT THE CENTRAL AND NORTHERN HIGH PLAINS. HEAT IS ALSO
FORECAST TO REBUILD ACROSS THE SOUTHEAST BY SATURDAY AS UPPER
RIDGING RETURNS. HIGHS INTO THE MID-TO-UPPER 90S ARE FORECAST,
WITH HEAT INDICES INTO THE TRIPLE DIGITS WHEN HUMIDITY LEVELS ARE
FACTORED IN. BE SURE TO FOLLOW PROPER HEAT SAFETY, WHICH INCLUDES
STAYING HYDRATED AND LIMITING OUTDOOR ACTIVITY.
ELSEWHERE, MONSOONAL MOISTURE IS ANTICIPATED TO REMAIN THROUGHOUT
PARTS OF THE SOUTHWEST. STORMS COULD LEAD TO AREAS OF DAMAGING
WIND GUSTS THROUGH TONIGHT IN SOUTHEAST NEW MEXICO, AS WELL AS
LOCALIZED FLASH FLOODING. ACTIVE WEATHER ALSO RETURNS TO THE
NORTHERN PLAINS AND UPPER MIDWEST BY THE WEEKEND WITH SCATTERED
SEVERE THUNDERSTORMS AND HEAVY RAIN POSSIBLE AHEAD OF AN
APPROACHING COLD FRONT. A SLIGHT RISK (LEVEL 2/5) OF SEVERE
WEATHER HAS BEEN ISSUED FOR SATURDAY BY THE STORM PREDICTION
CENTER.
