...EXCESSIVE HEAT WARNINGS IN EFFECT ACROSS THE CALIFORNIA'S
CENTRAL VALLEY AND MUCH OF THE DESERT SOUTHWEST...
..HEAT GRADUALLY BECOMES LESS INTENSE OVER SOUTHERN TEXAS
...SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED TO MOVE THROUGH
THE EASTERN U.S. FOR THE NEXT COUPLE OF DAYS WITH LOCALLY HEAVY TO
EXCESSIVE RAINFALL POSSIBLE OVER THE CENTRAL APPALACHIANS THROUGH
TONIGHT...
OVER THE NEXT COUPLE OF DAYS, A SHIFT IN THE WEATHER PATTERN WILL
CONTINUE TO PUSH THE ACTIVE WEATHER ACROSS THE EASTERN U.S. THIS
SHIFT IN THE WEATHER PATTERN WILL ALSO SUSTAIN A HEATWAVE ACROSS
THE SOUTHWESTERN U.S. HIGH TEMPERATURES WELL UP INTO THE 100S
THIS AFTERNOON ACROSS THE CENTRAL VALLEY OF CALIFORNIA COULD SOAR
A COUPLE DEGREES HIGHER THURSDAY AFTERNOON. THE DESERT SOUTHWEST
WILL LIKELY SEE TEMPERATURES SOARING INTO THE 110S THURSDAY
AFTERNOON, WITH LAS VEGAS' HIGH TEMPERATURE CHALLENGING/REACHING
ITS EARLIEST 112 DEGREES ON RECORD. WIDESPREAD HIGH AND LOW
TEMPERATURE RECORDS MAY BE TIED OR BROKEN THROUGH FRIDAY.
EXCESSIVE HEAT WARNINGS ARE IN EFFECT FOR CALIFORNIA'S CENTRAL
VALLEY AS WELL AS MUCH OF THE DESERT SOUTHWEST INCLUDING
SOUTHEASTERN CALIFORNIA, SOUTHERN NEVADA AND WESTERN/SOUTHERN
ARIZONA. RECORD WARM LOW TEMPERATURES AT NIGHT WILL NOT OFFER
MUCH CHANCE TO COOL OFF EITHER. THE HEAT IS FORECAST TO EXPAND
NORTHWARD ACROSS THE GREAT BASIN AND INTO THE INTERIOR PACIFIC
NORTHWEST ON FRIDAY WITH HIGHS REACHING WELL UP INTO THE 90S.
MEANWHILE, THE HEAT ACROSS SOUTHERN TEXAS IS FORECAST TO BECOME
LESS INTENSE OVER THE NEXT COUPLE OF DAYS.
MUCH COOLER, DAMP, AND WINDY CONDITIONS WILL GRADUALLY SPREAD FROM
THE NORTHERN PLAINS EASTWARD INTO THE UPPER MIDWEST AND THE GREAT
LAKES THROUGH THE NEXT COUPLE OF DAYS BEHIND THE COLD FRONT
TRAILING SOUTH FROM A DEEP LOW PRESSURE SYSTEM OVER SOUTHERN
CANADA. THE SYSTEM WILL PUSH STEADILY EASTWARD, PROVIDING A BREAK
IN THE ACTIVE WEATHER OVER THE MID-SECTION OF THE COUNTRY WHILE
SPREADING SHOWERS AND EMBEDDED THUNDERSTORMS ACROSS THE GREAT
LAKES, OHIO AND TENNESSEE VALLEYS, AND DOWN TOWARD THE LOWER
MISSISSIPPI VALLEY THROUGH TONIGHT. THE INCLEMENT WEATHER WILL
REACH INTO MUCH OF THE EAST COAST ON THURSDAY AS THE COLD FRONT
CONTINUES ITS EASTWARD PROGRESS. THERE APPEARS TO BE A GREATER
CHANCE FOR NEW ENGLAND TO SEE SOME LOCALLY HEAVY RAIN WITH
EMBEDDED THUNDERSTORMS LATER ON THURSDAY AS A WARM FRONT LIFTING
NORTHWARD MEETS THE EASTWARD-ADVANCING COLD FRONT. MORE ROUNDS OF
SHOWERS ARE EXPECTED FOR THE INTERIOR NORTHEAST ON FRIDAY AS
ADDITION ENERGY ROTATES ACROSS THE GREAT LAKES TOWARD NEW ENGLAND.
BY LATER ON FRIDAY, A LOW PRESSURE SYSTEM WILL BE ORGANIZING OVER
THE CENTRAL PLAINS WITH SUPPORT FROM UPPER-LEVEL ENERGY EJECTING
EASTWARD FROM THE CENTRAL ROCKIES. SHOWERS AND THUNDERSTORMS WILL
BEGIN TO DEVELOP AND EXPAND AHEAD OF THE SYSTEM OVER THE CENTRAL
PLAINS BY FRIDAY AFTERNOON. SCATTERED THUNDERSTORMS WILL ALSO
DEVELOP OVER THE CENTRAL ROCKIES.
