...DANGEROUS HEAT WILL CONTINUE TO IMPACT PORTIONS OF THE WEST
INTO THIS WEEKEND...
...HEAVY RAIN AND FLASH FLOODING ARE LIKELY ALONG THE CENTRAL GULF
COAST AND SOUTHEAST OVER THE NEXT FEW DAYS...
IN THE WEST, A STRONG UPPER LEVEL RIDGE WILL REMAIN OVERHEAD
THROUGH SATURDAY, RESULTING IN WELL ABOVE AVERAGE AND POTENTIALLY
DANGEROUS TEMPERATURES FOR PORTIONS OF THE WEST. HIGH TEMPERATURES
WILL ONCE AGAIN REACH THE TRIPLE DIGITS IN THE SOUTHWEST AND PARTS
OF INTERIOR CALIFORNIA ON SATURDAY, AND HIGHS COULD EXCEED 110
DEGREES IN THE HOTTEST LOCATIONS OF THE DESERT SOUTHWEST.
TEMPERATURES WILL BE HEATING UP IN THE INTERIOR NORTHWEST AS WELL,
WITH WIDESPREAD HIGH TEMPERATURES WELL INTO THE 90S. THESE
TEMPERATURES WILL RESULT IN A MODERATE TO EXTREME HEATRISK, AND
THIS LEVEL OF HEAT IS DANGEROUS FOR ANYONE WITHOUT ADEQUATE
COOLING OR HYDRATION. RESIDENTS AND VISITORS ARE ADVISED TO FOLLOW
PROPER HEAT SAFETY, WHICH INCLUDES CHECKING ON VULNERABLE
INDIVIDUALS. POOR AIR QUALITY WILL ALSO REMAIN AN ISSUE THROUGHOUT
PARTS OF THE NORTHWEST AS WILDFIRE SMOKE CONTINUES TO PLAGUE THE
REGION. TEMPERATURES SHOULD DECREASE ACROSS THE WEST SUNDAY INTO
MONDAY AS THE RIDGE SHIFTS EAST OVER THE CENTRAL UNITED STATES,
AND SCATTERED LIGHT SHOWERS AND STORMS WILL BE POSSIBLE AS A WEAK
UPPER LEVEL WAVE MOVES ACROSS THE REGION.
IN THE EASTERN HALF OF THE NATION, A FALL-LIKE AIRMASS WILL MOVE
INTO PLACE BEHIND A COLD FRONT THAT WILL MOVE TOWARDS THE EAST
COAST ON SATURDAY. BELOW NORMAL TEMPERATURES ARE FORECAST FROM THE
EASTERN PLAINS TO THE EAST COAST THIS WEEKEND, WITH HIGH
TEMPERATURES REACHING AS LOW AS 10-20 DEGREES BELOW NORMAL IN SOME
AREAS. HIGHS WILL GENERALLY BE IN THE 60S AND 70S FOR MOST OF THE
CENTRAL AND EASTERN U.S., AND IN THE 80S FOR THE SOUTH AND
SOUTHEAST. SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE ALONG THE
FRONT AS IT MOVES THROUGH THE EAST, BUT STRONG HIGH PRESSURE WILL
RESULT IN DRY CONDITIONS BEHIND THE FRONT. HEAVY PRECIPITATION
WILL BE CONFINED TO THE CENTRAL GULF COAST AND THE SOUTHEAST WHERE
A LINGERING STATIONARY FRONT WILL TRIGGER SHOWERS AND STORMS
THROUGH THE WEEKEND AND EARLY NEXT WEEK. HEAVY RAIN MAY RESULT IN
SCATTERED INSTANCES OF FLASH FLOODING, ESPECIALLY IF RAIN FALLS IN
AREAS THAT ALREADY RECEIVED HEAVY RAIN OVER THE PAST FEW DAYS.
REMEMBER, IT IS NEVER SAFE TO WALK OR DRIVE INTO FLOOD WATERS, AND
MOST FLOOD FATALITIES OCCUR IN VEHICLES... TURN AROUND, DON'T
DROWN!
