354 AM EDT FRI OCT 04 2024  
 
VALID 12Z FRI OCT 04 2024 - 12Z SUN OCT 06 2024  
 
...RECORD-BREAKING HEAT REMAINS ACROSS CALIFORNIA AND THE  
SOUTHWEST THROUGH THIS WEEKEND, WHILE ALSO BUILDING INTO THE  
CENTRAL UNITED STATES ON SATURDAY...  
 
...STRONG WINDS AND DANGEROUS FIRE WEATHER CONCERNS FORECAST  
THROUGHOUT THE NORTHERN GREAT BASIN, NORTHERN ROCKIES, AND INTO  
THE NORTHERN/CENTRAL PLAINS...  
 
...LOCALLY HEAVY RAIN POSSIBLE ACROSS THE IMMEDIATE GULF COAST AS  
UNSETTLED WEATHER DEVELOPS IN THE GULF OF MEXICO...  
 
A FALL HEATWAVE WILL CONTINUE INTO THE WEEKEND OVER PORTIONS OF  
THE DESERT SOUTHWEST AND CENTRAL/SOUTHERN CALIFORNIA AS A  
PERSISTENT TREND OF UPPER-RIDGING OVER THE REGION REMAINS IN  
PLACE. NUMEROUS RECORD-TYING/BREAKING HIGHS ARE FORECAST AS  
TEMPERATURES SOAR ONCE AGAIN INTO THE UPPER 90S TO 100S.  
HEAT-RELATED ADVISORIES/WARNINGS ARE IN PLACE AS THE HEAT REMAINS  
AT LEVELS DANGEROUS TO ANYONE WITHOUT ADEQUATE COOLING OR  
HYDRATION. WHILE NOT QUITE AS HOT, TEMPERATURES WILL STILL BE  
WELL-ABOVE AVERAGE FRIDAY ELSEWHERE ACROSS THE INTERIOR WEST, WITH  
HIGHS WELL INTO THE 80S FOR MANY LOCATIONS ACROSS THE  
NORTHERN/CENTRAL ROCKIES AND GREAT BASIN. A COLD FRONT WILL BRING  
COOLER, MORE FALL-LIKE TEMPERATURES TO THE NORTHERN GREAT  
BASIN/ROCKIES ON SATURDAY. HIGHER HEIGHTS WILL ALSO EXPAND  
EASTWARD OVER THE CENTRAL UNITED STATES ON SATURDAY HELPING TO  
SPREAD MUCH ABOVE AVERAGE TEMPERATURES INTO PORTIONS OF THE  
CENTRAL/SOUTHERN PLAINS AND UPPER MIDWEST. FORECAST HIGHS IN THE  
80S TO LOW 90S IN THE UPPER MIDWEST AND AS HIGH AS THE MID-90S IN  
THE CENTRAL PLAINS ARE UPWARDS OF 20 DEGREES ABOVE AVERAGE, WITH  
RECORD-TYING/BREAKING HIGHS POSSIBLE HERE AS WELL.  
 
A FAST-MOVING UPPER-LEVEL WAVE/ACCOMPANYING SURFACE FRONTAL SYSTEM  
WILL PASS ALONG THE NORTHERN TIER OF THE WEST AND INTO THE CENTRAL  
U.S. OVER THE NEXT COUPLE OF DAYS. SOME MODERATE TO LOCALLY HEAVY  
RAINFALL WILL BE POSSIBLE OVER THE PACIFIC NORTHWEST ON FRIDAY,  
WITH SOME LIGHTER SHOWERS INTO THE NORTHERN ROCKIES. ADDITIONAL  
SHOWERS/STORMS WILL ACCOMPANY THE SYSTEM AS IT REACHES THE UPPER  
GREAT LAKES LATER SATURDAY AND INTO THE EARLY MORNING HOURS  
SUNDAY. HOWEVER, THE BIGGER STORY WILL BE WIDESPREAD GUSTY WINDS  
AND HIGH FIRE DANGER WITH THE FAST MOVING SYSTEM AS IT PASSES  
THROUGH THE NORTHERN GREAT BASIN/ROCKIES FRIDAY AND INTO THE  
NORTHERN HIGH PLAINS SATURDAY. WIND-RELATED WATCHES AND WARNINGS  
HAVE BEEN ISSUED AS GUSTS HIGHER THAN 60 MPH CAN BE EXPECTED,  
LEADING TO RISK OF BLOWING DEBRIS, POTENTIAL PROPERTY DAMAGE, AND  
ISOLATED POWER OUTAGES, AS WELL AS DIFFICULT TRAVEL CONDITIONS  
ESPECIALLY FOR HIGH-PROFILE VEHICLES. IN ADDITION, THE GUSTY WINDS  
AND VERY DRY CONDITIONS AHEAD OF THE APPROACHING COLD FRONT WITH  
THE SYSTEM WILL BRING AN INCREASED THREAT FOR WILDFIRES. THE STORM  
PREDICTION CENTER HAS HIGHLIGHTED A CRITICAL RISK (LEVEL 2/3) OF  
FIRE WEATHER OVER PORTIONS OF THE NORTHERN GREAT BASIN AND  
CENTRAL/EASTERN WYOMING FRIDAY, AND THE CENTRAL ROCKIES INTO THE  
CENTRAL PLAINS ON SATURDAY. MUCH OF THE REST OF THE REGION IS  
UNDER RED FLAG WARNINGS AND FIRE WEATHER WATCHES.  
 
ENHANCED TROPICAL MOISTURE ALONG THE GULF COAST WILL LEAD TO  
PERIODS OF MODERATE TO LOCALLY HEAVY SHOWERS FOR THE NEXT FEW  
DAYS. THE LACK OF A FOCUSING SYSTEM/BOUNDARY AND SCATTERED NATURE  
OF THE STORMS CURRENTLY SUGGESTS A LOW RISK FOR FLASH FLOODING,  
BUT AN ISOLATED INSTANCE OR TWO OF FLASH FLOODING CANNOT BE RULED  
OUT. ELSEWHERE, SOME LIGHT TO MODERATE SHOWERS CAN BE EXPECTED  
WITH A COLD FRONTAL PASSAGE THROUGH THE NORTHEAST LATE  
FRIDAY/EARLY SATURDAY. HIGH TEMPERATURES WILL GENERALLY BE AT TO A  
BIT ABOVE AVERAGE FOR THE EASTERN U.S., WITH WIDESPREAD 70S TO THE  
NORTH AND 80S IN THE SOUTH.
