...EXCESSIVE RAINFALL IS FORECAST FOR THE TEXAS COAST THROUGH
TONIGHT WITH MORE SCATTERED SHOWERS AND THUNDERSTORMS ACROSS THE
SOUTHERN TIER STATES TO THE EAST COAST...
...MONSOONAL THUNDERSTORMS CONTINUE ACROSS THE GREAT BASIN AND
INTO THE FOUR CORNERS REGION WITH THREATS OF LOCALIZED FLASH
FLOODING...
A SLOW-TO-EVOLVE SUMMERTIME WEATHER PATTERN WILL CONTINUE ACROSS
MUCH OF THE U.S. MAINLAND WHILE A MORE PROGRESSIVE PACIFIC COLD
FRONT SWEEPS ACROSS THE NORTHWESTERN PART OF THE COUNTRY OVER THE
NEXT COUPLE OF DAYS. UNDER THIS PATTERN, UNSETTLED WEATHER AND
RELATIVELY COOL TEMPERATURES FOR JULY WILL CONTINUE ACROSS THE
SOUTH AS WELL AS THE GREAT LAKES. THE STRONGER FORCING ASSOCIATED
WITH THE PACIFIC FRONT WILL PUSH THE HEAT DOME INTO THE NORTHERN
HIGH PLAINS TONIGHT BENEATH A WARM FRONT, RESULTING IN ANOTHER
EVENING OF MAJOR TO LOCALLY EXTREME HEAT RISK FOR THE REGION. LOW
TEMPERATURES WILL ONCE AGAIN REACH WELL INTO THE 70S WITH LITTLE
TO NO RAINFALL EXPECTED. MEANWHILE, THE HEAT WILL CONTINUE TO
BECOME LESS INTENSE OVER THE CENTRAL VALLEY OF CALIFORNIA AND THE
DESERT SOUTHWEST UNTIL ALMOST COMPLETELY DIMINISHING FOR THE
REGION BY THE WEEKEND. SOME OF THE HOT AIR OVER THE NORTHERN
PLAINS WILL BE PUSHED INTO THE UPPER MIDWEST BY THE WEEKEND WITH
HIGHS REACHING INTO THE 80S AND 90S. PLEASE CONTINUE TO PRACTICE
HEAT SAFETY BEFORE COOLER AIR ARRIVES BEHIND THE COLD FRONT.
THE PACIFIC COLD FRONT CURRENTLY MAKING ITS WAY THROUGH THE
NORTHERN ROCKIES INTO THE HIGH PLAINS WILL GRADUALLY BECOME NEARLY
STATIONARY THROUGH THE NEXT COUPLE OF DAYS. LIGHTNING ASSOCIATED
WITH DRY THUNDERSTORMS TRIGGERED BY THE PASSAGE OF THE COLD FRONT
WILL RAISE FIRE DANGER CONCERNS OVER THE INTERIOR NORTHWESTERN
U.S. INTO THE NORTHERN HIGH PLAINS. FARTHER SOUTH, MONSOONAL
THUNDERSTORMS ACROSS THE GREAT BASIN WILL SHIFT FARTHER EASTWARD
INTO THE FOUR CORNERS AND AS FAR NORTH AS WYOMING OVER THE NEXT
COUPLE OF DAYS.
IN CONTRAST TO THE HEAT IN THE WEST, COOLER THAN NORMAL
TEMPERATURES WILL PREVAIL ACROSS THE MID-SECTION OF THE COUNTRY
AND PORTIONS OF THE EASTERN U.S. WHERE A STALLED FRONT WILL KEEP
PLENTY OF CLOUDS ALONG WITH SCATTERED THUNDERSTORMS. IT APPEARS
THAT COASTAL SECTIONS OF TEXAS WILL SEE THE HIGHEST CHANCE OF
RECEIVING HEAVY RAINFALL INTO TONIGHT AS SOME INFLUX OF TROPICAL
MOISTURE FROM THE GULF OF MEXICO COULD INTERACT WITH THE WEAK
FRONT UNDER A BROAD UPPER-LEVEL SOUTHWESTERLY FLOW AHEAD OF A
TROUGH. A MODERATE RISK OF EXCESSIVE RAINFALL REMAINS IN PLACE
FROM THE MID AND UPPER TEXAS COAST TO SOUTHWESTERN LOUISIANA
THROUGH TONIGHT. THUNDERSTORMS ACROSS OTHER AREAS OF THE SOUTHERN
TIER STATES ARE NOT EXPECTED TO BE SEVERE, BUT THEY COULD RESULT
IN LOCALIZED FLOODING ISSUES FROM TIME TO TIME. THE SAME IS TRUE
ALONG THE EAST COAST WITH A SLIGHT RISK OF EXCESSIVE RAINFALL OVER
PORTIONS OF THE CAROLINAS THROUGH FRIDAY NIGHT WHERE STORMS ARE
EXPECTED TO BE MORE NUMEROUS. MEANWHILE, SHOWERS AND A FEW
EMBEDDED THUNDERSTORMS ACROSS NEW ENGLAND WILL CLEAR OUT BY FRIDAY
AS A LOW PRESSURE WAVE MOVES AWAY INTO EASTERN CANADA.
