THE UNRELENTING SUMMER OF 2023 HEAT WAVE WILL CONTINUE IN EARNEST
ACROSS THE SOUTHERN TIER OF THE NATION FROM THE SOUTHWEST, THROUGH
CENTRAL TO SOUTH TEXAS AND ALONG MUCH OF THE GULF COAST, INCLUDING
FLORIDA, AS THE NEW WORK WEEK BEGINS. NUMEROUS RECORD HIGH

LIKELY OVER THE NEXT FEW DAYS WITH NO END IN SIGHT GOING INTO THE
LATER PART OF THIS WEEK. EXCESSIVE HEAT WARNINGS AND HEAT
ADVISORIES ARE CURRENTLY IN EFFECT ACROSS ALL OF THE SOUTHERN TIER
OF THE NATION FROM SOUTHEAST CALIFORNIA INTO FLORIDA AND WILL
LIKELY REMAIN IN EFFECT FOR THE FORESEEABLE FUTURE AS THERE IS NO
RELIEF IN SIGHT TO THE HEAT FOR THE REMAINDER OF THE WEEK ACROSS
THESE AREAS.
IN ADDITION TO THE HOT TEMPERATURES ACROSS THE SOUTHERN TIER OF
THE NATION, THERE WILL CONTINUE TO BE AN ELEVATED FIRE WEATHER
RISK ACROSS PORTIONS OF THE SOUTHWEST INTO THE SOUTHERN PLAINS.
DRY CONDITIONS, LOW RELATIVE HUMIDITIES AND GUSTY WINDS WILL
CONTINUE TO SUPPORT THE FIRE WEATHER THREAT ACROSS THESE AREAS.
A VERY ACTIVE THUNDERSTORM PATTERN IS EXPECTED OVER THE NEXT FEW
DAYS ACROSS LARGE SECTIONS OF THE NATION TO THE EAST OF THE
MISSISSIPPI RIVER. IN THE AREAS OF THUNDERSTORMS, SEVERE WEATHER
AND FLASH FLOODING WILL BE A THREAT. ACTIVE SHOWERS AND
THUNDERSTORMS EXPECTED TO CONTINUE FROM SUNDAY AFTERNOON INTO
SUNDAY EVENING FROM THE MID-WEST INTO PORTIONS OF THE GREAT LAKES,
MID ATLANTIC AND INTO THE SOUTHEAST. THIS ACTIVE SHOWER AND
THUNDERSTORM PATTERN WILL THEN AGAIN RE-INTENSIFY MONDAY AFTERNOON
FROM THE OHIO VALLEY INTO THE APPALACHIANS AND ALONG LARGE
PORTIONS OF THE EAST COAST FROM THE SOUTHEAST INTO THE NORTHEAST.
THESE ACTIVE AREAS OF STORMS ARE ASSOCIATED WITH A STRONG AREA OF
LOW PRESSURE AND ITS ASSOCIATED COLD FRONT EXPECTED TO PRESS
EASTWARD ACROSS LARGE PORTIONS OF THE NATION TO THE EAST OF THE
MISSISSIPPI RIVER OVER THE NEXT TWO DAYS.
A SEPARATE STORM SYSTEM PUSHING INLAND FROM THE NORTHEAST PACIFIC
INTO THE NORTHWESTERN PORTION OF THE NATION WILL SUPPORT
INCREASING SHOWER AND THUNDERSTORM ACTIVITY MONDAY FROM THE INLAND
REGIONS OF THE PACIFIC NORTHWEST TO THE EAST OF THE CASCADES AND
EASTWARD INTO THE NORTHERN ROCKIES. HEAVY RAINS AND ISOLATED
FLASH FLOODING ARE POSSIBLE, WITH FLOOD WATCHES CURRENTLY IN
EFFECT FROM NORTHEAST WASHINGTON STATE INTO NORTHERN IDAHO.
