...A DANGEROUS HEAT WAVE WILL IMPACT MUCH OF THE EAST COAST,
SOUTHEAST AND NORTHWEST THROUGH TONIGHT...
...EXCESSIVE RAINFALL CONCERNS ACROSS PORTIONS OF THE EASTERN U.S.
THIS WEEKEND...
...MONSOONAL STORMS CONTINUE ACROSS THE SOUTHWEST/FOUR CORNERS
THROUGH THE WEEKEND...
A FAMILIAR UPPER-LEVEL PATTERN OVER THE LOWER 48, WITH RIDGING IN
THE WEST AND TROUGHING OVER THE GREAT LAKES AND OHIO/TENNESSEE
VALLEY, WILL SUPPORT HEAT WAVES AND EXCESSIVE RAINFALL CONCERNS
THIS WEEKEND. HIGH TEMPERATURES IN THE 100S WILL REPRESENT A 10-15
DEGREE POSITIVE ANOMALY ACROSS THE NORTHWEST TODAY. SOME OF THESE
TEMPERATURES WILL TIE OR BREAK RECORDS. OVERNIGHT TEMPERATURES IN
THE UPPER 60S TO UPPER 70S WILL TIE OR BREAK WIDESPREAD
TEMPERATURE RECORDS ACROSS THE WEST TONIGHT AS WELL. THE
COMBINATION OF VERY HOT DAYTIME CONDITIONS AND A LACK OF OVERNIGHT
RELIEF COULD HARM THOSE WITHOUT ADEQUATE SHELTER OR HYDRATION.
CLOUDY CONDITIONS WILL SUPPORT NEAR RECORD BREAKING WARMTH OVER
PORTIONS OF THE COASTAL NORTHEAST AND FLORIDA PENINSULA TONIGHT.
SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG A COLD FRONT MOVING
THROUGH THE MIDWEST TODAY AND SPREAD EASTWARD TOWARD THE EAST
COAST. SLIGHT RISKS OF EXCESSIVE RAINFALL LEADING TO FLASH
FLOODING ARE IN EFFECT FOR PORTIONS OF THE LOWER GREAT LAKES, OHIO
VALLEY AND NORTHEAST TODAY DUE TO THE HIGHER RATES WITHIN SOME OF
THE STORMS THAT MOVE THROUGH THOSE AREAS. OROGRAPHIC LIFT OVER
PORTIONS OF THE CENTRAL/SOUTHERN APPALACHIANS WILL PROMOTE
ADDITIONAL FLASH FLOODING CONCERNS, HENCE ANOTHER SLIGHT RISK AREA
FOR PARTS OF EASTERN TENNESSEE, SOUTHEASTERN KENTUCKY,
SOUTHWESTERN VIRGINIA, WESTERN NORTH CAROLINA AND NORTHERN
ALABAMA/GEORGIA. THE COLD FRONT SLOWS DOWN ACROSS THE
MID-ATLANTIC/SOUTHEAST ON SATURDAY AND BECOMES THE FOCUS FOR
ADDITIONAL EXCESSIVE RAINFALL CONCERNS, DUE IN PART TO A
SIGNIFICANT MOISTURE PLUME FROM THE TROPICS. A SLIGHT RISK OF
EXCESSIVE RAINFALL IS IN EFFECT FOR PORTIONS OF SOUTHEASTERN
VIRGINIA DOWN INTO THE CAROLINA/GEORGIA PIEDMONT.
A TROPICAL DISTURBANCE IS FORECAST TO IMPACT THE FLORIDA PENINSULA
BEGINNING LATE TONIGHT WHEN HEAVY RAINFALL AND THUNDERSTORMS ARE
SUPPOSED TO SPREAD ACROSS SOUTHERN FLORIDA AND EVENTUALLY WORK
THEIR WAY UP THE PENINSULA ON SATURDAY. A SLIGHT RISK OF EXCESSIVE
RAINFALL IS IN EFFECT FOR PORTIONS OF SOUTHERN FLORIDA ON SATURDAY
AS A RESULT. MONSOONAL MOISTURE IS EXPECTED TO CONTINUE FLOWING
INTO THE SOUTHWEST/FOUR CORNERS REGION THIS WEEKEND. SCATTERED
SHOWERS AND THUNDERSTORMS MAY LEAD TO ISOLATED FLASH FLOODING
ACROSS PORTIONS OF THE AFOREMENTIONED AREAS, PARTICULARLY BURN
SCARS AND SLOT CANYONS.
