AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
349 AM MDT SAT JUL 19 2008

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT...
THUNDERSTORM OUTFLOW OVER THE FAR NORTH PART OF THE CWA EARLY THIS
MORNING HAS PRODUCED BRISK NORTHERLY WINDS AND LOW CLOUDS.  AS OF
09Z THE EDGE OF THE LOW CLOUD DECK WAS OVER EASTERN NIOBRARA COUNTY
TO DAWES AND NORTHERN SIOUX COUNTIES.  SATELLITE IMAGERY SHOWS THE
CLOUD AREA SPREADING SOUTH AND THE QUESTION IS HOW FAR SOUTH.  THE
LATEST RUC PICKS UP ON THE HIGHER MOISTURE IN THE BOUNDARY LAYER AND
MOVES THE CLOUDS TO A KLSK TO KBFF TO BRIDGEPORT LINE BY 12Z.  SURFACE
DEWPOINTS BELOW AROUND 5000 FEET MSL WERE IN THE 50S TO 65 AND HAVE
ALSO KEPT THE MENTION OF FOG MAINLY BELOW THAT ELEVATION.  OTHERWISE
TODAY AND SUNDAY WILL CONTINUE TO BE HOT WITH 700 MB TEMPERATURES
BETWEEN 16C AND 18C.  THE ATMOSPHERE WILL BE VERY DRY OVER THE CWA
TODAY AND EXPECT ONLY SOME CUMULUS TO FORM IN THE AFTERNOON.  ALL OF
THE MODELS INDICATE THE 500 MB TO 300 MB LAYER RELATIVE HUMIDITY TO
INCREASE SUNDAY MORNING OVER THE WEST PART OF THE CWA AND THEN OVER
THE ENTIRE CWA BY SUNDAY AFTERNOON AND CONTINUING FOR SUNDAY NIGHT.
MOST OF THE MOISTURE WILL BE ABOVE 500 MB...BUT THERE SHOULD BE
ENOUGH FOR ISOLATED HIGH BASED THUNDERSTORMS SUNDAY AFTERNOON AND
EVENING.  EXPECT THE WIND GUSTS FROM THE STORMS BUT HAVE NOT ADDED
THAT WORDING TO THE FORECAST AT THIS TIME.  FIRE WEATHER CONCERNS
WILL INCREASE BY MIDDAY AND PERSIST THROUGH THE EARLY EVENING IN THE
HOT...DRY AND BREEZY CONDITIONS.  THIS IS DISCUSSED FURTHER IN THE
FIRE WEATHER PART OF THE DISCUSSION.

.LONG TERM...WESTERLY FLOW WILL BE ALOFT OVER THE CWA MON AND TUES
WITH AN UPPER RIDGE OVER THE ROCKIES.  SOME MONSOONAL MOISTURE WILL
FLOW INTO THE AREA FROM THE SOUTH.  A FEW DISTURBANCES IN THE FLOW
WILL MOVE ACROSS THE FORECAST AREA LATE MON AND AGAIN LATE TUES.
ALL THIS WILL RESULT IN A CHANCE OF LATE DAY THUNDERSTORMS ACROSS
THE CWA BOTH DAYS.  FOR WED...THE WESTERLY FLOW WILL CONTINUE ALOFT
WITH THE UPPER RIDGE REMAINING OVER THE ROCKIES.  DRIER AIR WILL
WORK INTO THE NORTHERN HALF OF THE CWA PUSHING THE MOISTURE PLUME TO
THE SOUTH.  THIS WILL LIMIT THE LATE DAY THUNDERSTORMS TO SOUTHERN
MOUNTAINS AND AREAS ALONG THE CO BORDER.  FOR THUR AND FRI...THE
UPPER RIDGE WILL AMPLIFY OVER THE ROCKIES AND GREAT PLAINS AND THE
AXIS WILL SHIFT TO THE CENTRAL U.S.  MOISTURE PLUME SHOULD REMAIN TO
THE SOUTH OF THE STATE...SO MAY HAVE TO LOWER SLIGHT CHANCE OF
THUNDERSTORMS NOW IN FORECAST FOR THUR AND FRI AS THIS TIME
APPROACHES AND SOLUTION IN MODELS BECOMES CLEARER.  HIGH
TEMPERATURES WILL BE FROM 4 TO 8 DEGREES ABOVE NORMAL THROUGH THE
PERIOD.

&&

.AVIATION...IFR CEILINGS OVER THE AREA FROM KLSK TO KCDR EARLY THIS
MORNING WILL CONTINUE TO SLOWLY SPREAD SOUTH UNTIL BETWEEN 12Z AND
15Z.  LATEST RUC HAS THOSE CEILINGS SPREADING TO A KLSK TO BRIDGEPORT
LINE BY 12Z AND LOOKS REASONABLE AT THIS TIME.  THE IFR CONDITIONS
WILL AFFECT THE AIRPORTS AT KBFF...KCDR AND KAIA UNTIL BETWEEN 12Z
AND 15Z.  LAPS RAOBS INDICATE THE CLOUD DEPTH UP TO ABOUT 1000 FEET.
THERE WILL BE TURBULENT CONDITIONS AT THAT LEVEL AS THE WINDS THEN
SHIFT TO THE WEST FROM THE CURRENT NORTH AT THE SURFACE.
VISIBILITIES WILL ALSO BE LOWERED NOW THROUGH 15Z AT ELEVATIONS
BELOW 5000 FEET MSL AND WILL REACH AT LEAST MVFR CONDITIONS IN
PLACES.  OTHERWISE VFR CONDITIONS WILL BE OVER THE CWA THROUGH
SUNDAY NIGHT WITH GUSTY WEST WINDS TO 30 KNOTS MAINLY WEST OF
INTERSTATE 25 FROM MID MORNING THROUGH EARLY THIS EVENING.

&&

.FIRE WEATHER...IT WILL BE ANOTHER HOT...DRY AND BREEZY DAY TODAY
OVER MUCH OF THE CWA.  THIS WILL BE ESPECIALLY THE CASE IN THE LOWER
ELEVATIONS OF CARBON COUNTY AND THE NORTHERN LARAMIE RANGE.  LATEST
FUEL STATUS INDICATES THAT FUELS ARE DRY ENOUGH IN THOSE AREAS TO
SUPPORT FIRE GROWTH.  THE RELATIVE HUMIDITES WILL BE BETWEEN 8 AND
13 PERCENT FROM LATE MORNING TO EARLY EVENING.  AROUND 06Z...KRWL
HAD A RELATIVE HUMIDITY OF 12 PERCENT BEFORE SLIGHTLY MORE MOIST
AIR MOVED INTO THAT AREA.  WEST WINDS WILL GUST TO BETWEEN 25 AND
35 MPH BY LATE MORNING THROUGH EARLY EVENING AND WERE ALREADY
GUSTING TO AROUND 20 MPH AT KBRX AND NEAR KEBK.  WILL GO AHEAD AND
ISSUE A RED FLAG WARNING FOR FIRE WEATHER ZONES 293 AND 294 FROM
LATE MORNING THROUGH EARLY EVENING.
