NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
406 AM EDT SAT AUG 03 2024
VALID 12Z SAT AUG 03 2024 - 12Z MON AUG 05 2024
...A DANGEROUS HEAT WAVE SHIFTS FROM THE PACIIFC NORTHWEST TO THE
GREAT PLAINS...
...STORMY CONDITIONS AND FLASH FLOOD POTENTIAL ACROSS PORTIONS OF
THE EASTERN U.S. THIS WEEKEND...
...POTENTIAL TROPICAL CYLONE FOUR WILL BRING HAZARDOUS RAINFALL,
STRONG WINDS AND LIFE THREATENING STORM SURGE INUNDATION TO
PORTIONS OF FLORIDA THIS WEEKEND...
UPPER-LEVEL RIDGING OVER THE WEST WILL PROMOTE ABOVE AVERAGE
TEMPERATURES ACROSS THE REGION THIS WEEKEND. UPPER TROUGHING OVER
THE EAST PACIFIC WILL WORK IN COMBINATION WITH THE WESTERN RIDGE
TO PRODUCE HIGH TEMPERATURES IN THE UPPER 90S TO LOW 100S ACROSS
MUCH OF THE NORTHWEST INTO THE NORTHERN/CENTRAL PLAINS TODAY. WARM
OVERNIGHT LOWS IN THE UPPER 60S TO LOW 70S WILL REPRESENT 20-30
DEGREE ANOMALIES FOR MUCH OF THE NORTHERN GREAT BASIN/ROCKIES/HIGH
PLAINS TONIGHT. THE LACK OF OVERNIGHT RELIEF FROM THE HEAT WILL
AFFECT ANYONE WITHOUT EFFECTIVE COOLING AND/OR ADEQUATE HYDRATION.
A SMALL BIT OF MID-LEVEL ENERGY WILL CONTRIBUTE TO A SEVERE
THUNDERSTORM THREAT OVER THE NORTHERN PLAINS AND UPPER MIDWEST
THIS AFTERNOON/EVENING. DAMAGING WINDS, ISOLATED FLASH FLOODING
AND HAIL WILL BE THE PRIMARY THREATS THERE. SHORTWAVE ENERGY
SPINNING ACROSS THE NORTHERN PERIPHERY OF A MID-LEVEL CLOSED HIGH
PRESSURE BUBBLE WILL BRING SOME SCATTERED SHOWERS, THUNDERSTORMS
AND COOLER TEMPERATURES TO THE NORTHERN TIER OF THE COUNTRY
BEGINNING ON SUNDAY. MEANWHILE, WARM AIR SHIFTS INTO THE CENTRAL
PLAINS AND MIDDLE MISSISSIPPI VALLEY THROUGH EARLY NEXT WEEK.
ELSEWHERE, UPPER TROUGHING OVER THE OHIO/TENNESSEE VALLEY WILL
PROMOTE SCATTERED THUNDERSTORMS UP AND DOWN THE EAST COAST TODAY.
SLIGHT RISKS OF EXCESSIVE RAINFALL AND SEVERE THUNDERSTORMS ARE IN
EFFECT FROM THE TRI-STATE AREA DOWN TO THE FLORIDA PANHANDLE.
DAMAGING WIND GUSTS AND FLASH FLOODING WILL BE THE PRIMARY
CONCERNS FROM THESE STORMS. SOME LINGERING SHOWERS AND
THUNDERSTORMS ARE EXPECTED ON SUNDAY WITH ONLY AN ISOLATED THREAT
OF SEVERE STORMS AND FLASH FLOODING ACROSS THE COASTAL
MID-ATLANTIC/NORTHEAST.
TROPICAL DEPRESSION FOUR IS FORECAST TO STRENGTHEN INTO A TROPICAL
STORM AS IT TRACKS WEST OF THE FLORIDA PENINSULA THIS WEEKEND.
HEAVY RAINFALL, STRONG WINDS AND LIFE THREATENING STORM SURGE
INUNDATION ARE ALL POSSIBLE ALONG THE WESTERN COAST OF THE STATE
BEGINNING TODAY. HEAVY RAINFALL, STRONG WINDS AND STORM SURGE ARE
ALSO POSSIBLE OVER NORTHERN FLORIDA AND THE SOUTHEAST U.S. COAST
SUNDAY EVENING INTO EARLY NEXT WEEK. TROPICAL STORM WARNINGS AND
STORM SURGE WATCHES ARE IN EFFECT ALONG FLORIDA'S GULF COAST WHILE
TROPICAL STORM WATCHES EXTEND FARTHER OUT ACROSS THE OTHER GULF
COAST STATES. FOR MORE INFORMATION GO TO HURRICANES.GOV.
