AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
957 AM MDT SAT AUG 25 2007

.DISCUSSION...MOST OF THE FOG HAS LIFTED AS OF 1530Z.  THE AREA OF
LOW CLOUDS ALSO CONTINUES TO SHRINK AND AT THAT TIME WAS MAINLY
CONFINED TO PARTS OF THE SOUTHERN NEBRASKA PANHANDLE.  FOR THE REST
OF TODAY THE ATMOSPHERE OVER THE CWA WILL BE DRY WITH A CAPPING
MID LEVEL INVERSION OVER EASTERN PORTIONS.  MAIN CONCERN WILL BE
WITH FIRE WEATHER THIS AFTERNOON.

.PREVIOUS DISCUSSION  /ISSUED AT 320 AM MDT SAT AUG 25 2007/

SHORT TERM...TODAY THRU SUN NIGHT...WEAK LIFT FROM HIGH LEVEL TROF
MOVING THRU AREA COMBINED WITH SOME MSTR/LIFT ALONG FRONTAL BNDRY
ALOFT RESULTING IN AREA OF LOW/MID LEVEL CLDS OVER SE WY INTO CNTRL
AND SRN PARTS OF PNHNDL.  EXPECT CLDS TO DECREASE FROM W TO E THIS
MRNG AS UPPER FEATURE MOVES EAST.  CLDS WILL LIKELY PREVENT MORE
WIDESPRD LOW CLDS/FOG FROM FORMING.  BY LATE THIS MRNG...EXPECT
MOSTLY SUNNY SKIES AS DRY AIR IN WNW FLOW ALOFT REMAINS OVER THE
AREA.  FLAT UPPER RIDGE PASSES ACROSS THE REGION TNGT...WITH FLOW
BECMG WSW SUN AFTN/NIGHT WHICH ADVECTS SOME MID LEVEL MSTR INTO THE
REGION.  AIRMASS LOOKS TOO DRY IN LOWER LAYERS TO REALLY SUPPORT ANY
RAIN FROM REACHING GROUND...SO HAVE KEPT DRY FOR NOW.  HOT AND
BREEZY CONDITIONS RETURN FOR SUN (SEE FIRE WX BELOW).

LONG TERM...MONDAY THROUGH FRI...SFC RIDGE EDGING INTO THE NRN HI
PLAINS WILL BRING A LITTLE COOLER TEMPS TO MAINLY THE ERN CWA MONDAY
WHILE SFC FRONT STALLS ALONG THE MTNS.  WIDLE SCTD AFTN AND EVENG
SHOWERS AND TSTRMS POSSIBLE IN WEAK UPSLOPE FLOW BUT BETTER MOISTURE
LOOKS TO STAY JUST SOUTH IN COLORADO.  LITTLE CHANGE IN OVERALL
PATTERN TUESDAY THRU THURSDAY AS SFC RIDGE HOLDS OVER THE NRN PLAINS
INTO THE GRT LAKES REGION WITH RETURN FLOW LIKELY BRINGING UP SOME
MOSTURE ALONG THE MTNS FOR MAINLY LATE DAY CONVECTION.  WARMER AND
MAINLY DRY WX EXPECTED FRIDAY AS UPPER HIGH BUILDS SOME OVER THE 4
CORNERS REGION AND LOW LEVEL MOISTURE SHIFTS SOUTHWARD.

&&

.AVIATION...IFR CEILINGS WILL CONTINUE OVER PARTS OF THE SOUTHERN
PANHANDLE THROUGH 1730Z.  ON SATELLITE IMAGERY THE AREA HAS BEEN
SLOWLY ERODING SINCE 14Z AND MORE QUICKLY SINCE 1530Z.  THE AIRPORTS
AT KIBM AND KSNY WILL BE IMPACTED.  OTHWERWISE VFR CONDITIONS WILL
PREVAIL THROUGH TONIGHT.  SURFACE WINDS WILL INCREASE OVER THE CWA
BY MIDDAY AND WILL CAUSE SOME TURBULENCE NEAR THE GROUND...ESPECIALLY
OVER THE PANHANDLE AS WELL AS AT KRWL...KSAA AND KLAR.

&&

.FIRE WEATHER...WILL NEED TO MONITOR THE CONDITIONS IN THE WEST PART
OF THE CWA THIS AFTERNOON AS RED FLAG CRITERIA WILL BE APPROACHED.
HIGH TEMPERATURES WILL CLIMB ABOVE 80 AND THE MINIMUM RELATIVE
HUMIDITY WILL BE AROUND 15 PERCENT.  WINDS WILL ALSO INCREASE WITH
WINDS AT KVDW AND KARL AT 15Z ALREADY GUSTING TO 20 MPH.  THE LOWEST
GATE OF THE MEDICINE BOW PROFILER HAD 20 KNOT WINDS WITH 30 KNOT
WINDS AT 700 MB.  THE 700 MB WIND SPEEDS ARE GREATER THAN MODEL
FORECASTS.

HOT AND BREEZY CONDITIONS RETURN ON SUN AFTN AS
THERMAL RIDGE SHIFTS BACK INTO THE REGION.  HAVE OPTED TO POST FIRE
WX WATCH FOR W HALF OF AREA.  HAVE LEFT OUT E CNTRL AND SE WY PLAINS
AS WINDS LIKELY TO NOT REACH CRITERIA AND AREA STILL HASNT DRIED
OUT FROM WED NIGHT/THU PCPN.  SRN LAR RANGE WILL HAVE WINDS BUT
LATEST GUIDANCE ABOUT FUELS PLUS PCPN ON WED NIGHT/THU SUGGESTS WE
LEAVE THEM OUT OF WATCH FOR NOW.  LATER SHIFTS CAN MODIFY AS MORE
INFO BECOMES AVBL.
