...COOL AND FAIR WEATHER WILL PERSIST ACROSS THE NORTHEASTERN
QUADRANT OF THE COUNTRY AS TRIPLE-DIGIT HEAT CONTINUES ACROSS THE
SOUTHERN HALF OF THE PLAINS TO THE EASTERN GULF COAST...
...STRONG TO SEVERE THUNDERSTORMS ARE POSSIBLE OVER THE NORTHERN
HIGH PLAINS INTO TONIGHT AS SCATTERED SHOWERS AND THUNDERSTORMS
STRETCH ACROSS THE NORTH-CENTRAL PLAINS TOWARD THE MIDWEST...
...MONSOONAL RAINFALL WILL BECOME MORE WIDESPREAD ACROSS THE
DESERT SOUTHWEST AND INTO THE FOUR CORNERS REGION WHILE DRY
CONDITIONS PERSIST OVER THE PACIFIC NORTHWEST...
DURING THE NEXT COUPLE OF DAYS, A BROAD UPPER-LEVEL TROUGH WILL
DOMINATE THE WEATHER PATTERN ACROSS THE NORTHEASTERN QUADRANT OF
THE COUNTRY. THIS WILL KEEP A LARGE DOME OF COOL CANADA IN PLACE
ACROSS THE ENTIRE AREA AS THE COOL AIR WILL CONTINUE TO SPREAD
SOUTHWARD INTO THE CAROLINAS BEHIND A WELL-DEFINED COLD FRONT.
THE FRONT IS FORECAST TO REACH THE FLORIDA PANHANDLE BY TUESDAY
MORNING BEFORE BECOMING STATIONARY, BRINGING SOME LESS HUMID AIR
DOWN INTO THE SOUTHERN ATLANTIC STATES ON MONDAY. ON THE OTHER
HAND, THE COOL AIR WILL NOT PUSH AS FAR SOUTH ACROSS THE
MID-SECTION OF THE COUNTRY AS TRIPLE-DIGIT HEAT IS FORECAST TO
CONTINUE OVER THE SOUTHERN HALF OF THE GREAT PLAINS EASTWARD TO
THE EASTERN GULF COAST. TO THE NORTH OF THE FRONT, RELATIVELY
COOL AND UNSETTLED WEATHER IS EXPECTED TO PREVAIL ACROSS THE
NORTHERN PLAINS TOWARD THE MIDWEST, WHERE ROUNDS OF THUNDERSTORMS
CAN BE EXPECTED ESPECIALLY OVER THE NORTHERN HIGH PLAINS FOR THE
NEXT COUPLE OF DAYS AND PARTICULARLY THIS EVENING. FLORIDA WILL
REMAIN HOT AND HUMID WITH TYPICAL SUMMER-TIME SHOWERS AND
THUNDERSTORMS.
OVER THE SOUTHWESTERN PORTION OF THE COUNTRY, INCREASING SOUTHERLY
FLOW ALOFT IS FORECAST TO SPREAD MONSOONAL MOISTURE FARTHER NORTH
FROM THE SUBTROPICS AND MEXICO AS A HIGH PRESSURE CELL ALOFT EDGES
EASTWARD INTO THE SOUTHERN PLAINS. SHOWERS AND THUNDERSTORMS CAN
BE EXPECTED TO BECOME MORE WIDESPREAD ACROSS THE DESERT SOUTHWEST
AND INTO THE FOUR CORNERS REGION THROUGH THE NEXT COUPLE OF DAYS.
IN ADDITION, THE RAIN WILL HAVE A TENDENCY TO SPREAD FARTHER NORTH
INTO THE CENTRAL TO NORTHERN ROCKIES AS WELL AS THE NEARBY HIGH
PLAINS ON MONDAY, AND REMAIN IN THESE AREAS INTO TUESDAY.
MEANWHILE, DRY CONDITIONS ARE FORECAST TO PERSIST OVER THE PACIFIC
NORTHWEST UNDER THE PROTECTION OF AN EXTENSION OF THE UPPER-LEVEL
HIGH PRIOR TO THE ARRIVAL OF THE NEXT UPPER TROUGH FROM THE
EASTERN NORTH PACIFIC. TEMPERATURES WILL BE WARMER THAN NORMAL
OVER THE INTERMOUNTAIN REGION INTO THE NORTHERN ROCKIES AND THE
NORTHERN PLAINS BUT NEAR OR BELOW NORMAL CLOSER TO THE WEST COAST.
