What forecasters said that day
The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Riverton, WY wrote its last area forecast discussion before this red flag warning went out at Aug 1, 2:21 AM MDT, 14 minutes earlier.
Area forecast discussion, Aug 1, 2:21 AM MDT, 14 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RIVERTON WY 221 AM MDT FRI AUG 1 2008 .SHORT TERM...TODAY THROUGH SUNDAY NIGHT RIDGE OF HIGH PRESSURE CONTINUES TO LEAVE MOSTLY CLEAR SKIES ACROSS THE AREA THIS MORNING...THOUGH SMOKE FROM WILDFIRES ACROSS THE AREA CONTINUES TO IMPACT PORTIONS OF THE CWA. ANOTHER DAY OF HIGH PRESSURE IS EXPECTED TODAY...ALLOWING TEMPERATURES TO REACH INTO THE MID TO UPPER 90S FOR MANY LOCATIONS EAST OF THE DIVIDE...WITH LOCATIONS IN THE BIGHORN BASIN NEARING THE CENTURY MARK. TEMPERATURES IN THE MID TO UPPER 80S ARE EXPECTED IN THE WESTERN BASINS...WITH MID TO UPPER 70S ANTICIPATED OVER THE HIGHER ELEVATIONS. A TIGHTENED PRESSURE GRADIENT ASSOCIATED WITH A LOW PRESSURE SYSTEM MOVING OFF THE PACIFIC NORTHWEST COAST...WILL MIX WITH A WEAK SHORTWAVE EMBEDDED IN THE RIDGE TO CAUSE STRONG SOUTHWEST WINDS ACROSS MUCH OF THE STATE. MANY LOCATIONS SOUTHWEST OF A LINE FROM CODY TO MIDWEST WILL SEE WINDS OF 15 TO 20 MPH...WITH GUSTS OF 30. THE COMBINATION OF VERY LOW HUMIDITIES...WINDY CONDITIONS...AND DRY FUELS OVER THIS AREA HAS PROMPTED THE ISSUANCE OF A RED FLAG WARNING FOR TODAY. THE WARNING IS IN EFFECT FROM 12 PM THROUGH 8 PM THIS EVENING. BY 8 PM WINDS ARE EXPECTED TO DECREASE...AND RELATIVE HUMIDITIES SHOULD BEGIN TO RAISE ABOVE CRITICAL LEVELS. AS THE AFOREMENTIONED PACIFIC NORTHWEST SYSTEM MOVES FURTHER INLAND AND ADVANCES TOWARDS THE STATE THIS AFTERNOON AND EVENING...THE RIDGE AXIS WILL CONTINUE TO SLIDE EAST. THIS WILL ALLOW A GENERAL SOUTHWEST FLOW TO REMAIN OVER THE AREA. AN ADDITIONAL SHORTWAVE WILL MOVE ACROSS NORTHERN WYOMING SATURDAY AFTERNOON...PROVIDING ENOUGH INSTABILITY TO CAUSE ISOLATED SHOWERS AND THUNDERSTORMS ACROSS NORTHWESTERN WYOMING...ALONG WITH THE BIGHORN MOUNTAINS. GUSTY WINDS AND LIGHTNING WILL BE THE PRIMARY CONCERNS WITH THESE STORMS. WARM TEMPERATURES WILL CONTINUE SUNDAY. ANOTHER SYSTEM WILL MOVE OFF THE PACIFIC COAST ON SATURDAY AFTERNOON AND EVENING. THIS SYSTEM WILL SEND ANOTHER SHORTWAVE THROUGH NORTHERN WYOMING TO AID IN THE DEVELOPMENT OF ADDITIONAL SHOWER AND THUNDERSTORM ACTIVITY ON SUNDAY. .LONG TERM...MONDAY THROUGH FRIDAY LOOKS LIKE SOUTHWEST MONSOON MOISTURE WILL REMAIN SOUTH OF WYOMING IN THE EARLY EXTENDED PERIOD...MONDAY THROUGH TUESDAY. SHOULD REMAIN HOT AND DRY THROUGH THAT TIME FRAME. EXTENDED MODELS THEN WANT TO BRING MONSOON MOISTURE NORTH AND INTERACT IT WITH FAIRLY STRONG CANADIAN COLD FRONT WEDNESDAY...THURSDAY AND. ECMWF AND GFS NOT TOO FAR APART ON HEIGHT FIELDS IN EXTENDED. DO NOT TOTALLY BUY INTO STRONG MOISTURE SURGE AND COLD FRONTAL INTERACTION OVER THE AREA AS MODELS HAVE NOT BEEN DOING EXTREMELY WELL EVEN IN THE SHORT TERM THE PAST WEEK OR SO...WHICH LEADS TO SOME DEGREE OF DOUBT IN THE EXTENDED MODELS ABILITY TO DEAL WITH MESOSCALE CONVECTION DAYS 4 THROUGH 8. TEMPERATURES DO COOL WITH HIGHER HUMIDITY ACROSS THE NORTH AND EAST WEDNESDAY AND THURSDAY. WITH ONGOING LARGE WILDFIRES IN THE AREA...DO NOT WANT TO ADVERTISE TOO MUCH PRECIPITATION...COOLING AND INCREASE IN RELATIVE HUMIDITY WITHOUT A GREATER DEGREE OF CERTAINTY...THAT IS NOT WARRANTED AT THIS TIME. THE BIGGEST THING GOING FOR A MOISTURE SURGE NORTH IS THE FACT THAT IT IS SUPPORTED CLIMATOLOGICALLY THE FIRST TWO WEEKS OF AUGUST...BUT THE MOISTURE IS SUPPRESSED SO FAR SOUTH AT THIS TIME MAKING IT CLEAR THAT AN ABNORMAL PATTERN IS IN PLACE AND MUST TRANSITION BEFORE NORMALCY CAN BE EXPECTED WITH CONFIDENCE. OVERALL ISOLATED THUNDERSTORMS RETURN TO FORECAST WITH GREATEST CHANCE FOR PRECIPITATION IN MOUNTAINS. && .AVIATION... VFR CONDITIONS WILL OCCUR OVER THE REGION TODAY INTO THIS EVENING. AN ISOLATED SHOWER OR STORM MAY OCCUR OVER THE NW CORNER OF WY AFTER 21Z UNTIL 03Z. OTHERWISE BREEZY CONDITIONS OVER MUCH OF THE AREA IN THE AFTERNOON AND EARLY EVENING. SMOKE PLUMES CAN BE EXPECTED IN NORTHWEST WY THIS AFTERNOON AND EVENING WHERE TWO FIRES ARE ONGOING. THE SMOKE PLUMES WILL SPREAD ACROSS FAR NORTHERN WY WITH LOCAL MVFR CONDITIONS POSSIBLE IN THE VICINITY OF THE PLUMES. ANOTHER FIRE NORTH OF PINEDALE WILL PRODUCE A SMOKE PLUME THAT WILL SPREAD ACROSS CENTRAL WY IN THE AFTERNOON AND EVENING HOURS. MVFR VISIBILITY WILL BE LIKELY NEAR THIS SMOKE PLUME AS WELL. && .FIRE WEATHER... A DRY AND WINDY DAY WILL SET UP ACROSS THE STATE TODAY. RELATIVE HUMIDITIES OF 9 TO 15 PERCENT WILL BE FAIRLY COMMON ACROSS THE AREA...ESPECIALLY SOUTHWEST OF A LINE FROM CODY TO MIDWEST. ADDITIONALLY...A DISTURBANCE WILL MOVE THROUGH THE STATE THIS AFTERNOON TO HELP ELEVATE WINDS IN THE SAME AREA. WINDS OF 15 TO 20 MPH WITH GUSTS TO 30 MPH ARE EXPECTED. WITH THIS COMBINATION OF VERY LOW HUMIDITIES...STRONG WINDS...AND DRY FUELS... A RED FLAG WARNING HAS BEEN POSTED FOR MUCH OF THE FORECAST AREA FROM 12 PM THROUGH 8 PM THIS EVENING. WINDS ARE EXPECTED TO DECREASE DURING THE EVENING HOURS...WITH HUMIDITIES ALSO RECOVERING. WINDS WILL AGAIN INCREASE ON SATURDAY AFTERNOON ACROSS THE SOUTHWESTERN HALF OF THE FORECAST AREA...AND HUMIDITIES ARE EXPECTED TO AGAIN BE LOW. THIS SCENARIO WILL BE MONITORED TODAY FOR ADDITIONAL FIRE WEATHER CONCERNS. FOR NOW...BELIEVE THE WINDS MAY REMAIN BELOW CRITICAL LEVELS FOR SATURDAY. && .RIW WATCHES/WARNINGS/ADVISORIES... RED FLAG WARNING FROM NOON TODAY TO 8 PM MDT THIS EVENING FOR WYZ140-277>280-283-285-286-288-289-416. && SHORT TERM...BRANHAM LONG TERM...C.BAKER AVIATION...AR FIRE WEATHER...BRANHAM
