AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
515 PM MDT SAT MAY 28 2011

.DISCUSSION...
255 PM MDT SAT MAY 28 2011

EARLY AFTERNOON ANALYSIS OF IR IMAGERY/UPPER AIR DATA INDICATED A
BROAD MID/UPPER TROUGH OVER THE WESTERN CONUS. SOUTHWEST FLOW WAS
IN PLACE ACROSS THE TRI-STATE REGION WITH A WEAK SHORTWAVE TROUGH
NOTED OVER THE GREAT BASIN REGION.

FORECAST CONCERNS FOCUSED ON BOTH HIGH WIND POTENTIAL AREA-WIDE
AND CRITICAL FIRE WEATHER POTENTIAL FOR SOUTHWEST PORTIONS OF THE
REGION ON MONDAY FOLLOWED BY VERY WARM TEMPS FROM MID-WEEK ON. MAY
SEE THE FIRST 100 DEGREE DAY OF THE YEAR LATER THIS WEEK.

AFOREMENTIONED SHORTWAVE TROUGH WILL CONTINUE TO TRANSLATE EAST-
NORTHEASTWARD THIS EVENING BRINGING THE POTENTIAL FOR ELEVATED
CONVECTION TO PRIMARILY NORTHERN PORTIONS OF THE FORECAST AREA
AFTER 00Z. SHORT-RANGE HIGH RESOLUTION GUIDANCE DEPICTS CONVECTIVE
INITIATION OVER NORTHEASTERN COLORADO SHORTLY AFTER 01Z WITH MEAN
STORM MOTION TRANSLATING THESE STORMS TO THE NORTHEAST. ADDITIONAL
CONVECTION IS POSSIBLE ACROSS THE REGION BY AROUND 06Z. GIVEN
PRESENCE OF 750-1000 J/KG OF ELEVATED INSTABILITY...CAN'T RULE OUT
SOME HAIL BUT DON'T ANTICIPATE WIDESPREAD SEVERE WEATHER.

BIG BUST POTENTIAL FOR TEMPS ON SUNDAY AS THERE IS A SIGNIFICANT
SPREAD AMONGST THE VARIOUS NWP/MOS GUIDANCE. NAM IS PERSISTENT IN
KEEPING THE WARM FRONT OVER FAR SOUTHERN PORTIONS OF THE FORECAST
AREA RESULTING IN TEMPS STRUGGLING TO REACH THE 60 DEGREE MARK
NORTH OF US HIGHWAY 36. MEANWHILE...THE SREF/GFS/EC SOLUTION
PAINTS A MUCH WARMER PICTURE FOR THE AREA. HAVE SIDED WITH THE
PREPONDERANCE OF GUIDANCE IN GOING WITH A WARMER SOLUTION BUT DID
HEDGE TEMPS OVER THE NORTH TOWARD THE LOWER END OF THE WARM
GUIDANCE IN DEFERENCE TO THE NAM SOLUTION. SEE FIRE WEATHER
SECTION FOR DISCUSSION ON POTENTIAL FIRE WEATHER CONDITIONS
TOMORROW.

SHORTWAVE TROUGH/SURFACE LOW IS PROGGED TO DEEPEN AS IT SHIFTS
INTO THE NORTHERN PLAINS. SURFACE DRYLINE/COLD FRONT ARE PROGGED
TO PUSH THROUGH THE FORECAST AREA DURING THE DAY MONDAY. FIRE
WEATHER CONCERNS/POTENTIAL ARE DISCUSSED IN THE FIRE WEATHER
SUBSECTION BELOW. 6 HOUR PRESSURE RISES OF 5-6 MB AND A TIGHT
PRESSURE GRADIENT WILL LEAD TO THE POTENTIAL FOR HIGH WIND WARNING
CRITERIA ACROSS MUCH OF THE FORECAST AREA. RATHER THAN SPLITTING
HAIRS AT THIS POINT...PLACED THE ENTIRE AREA UNDER A HIGH WIND
WATCH GIVEN PROGGED H85/H7 FLOW. KEPT SLIGHT CHANCE POPS OVER THE
FAR EASTERN COUNTIES FROM MONDAY AFTERNOON THROUGH 06Z TUESDAY BUT
FEEL GREATEST THREAT FOR CONVECTION SHOULD RESIDE JUST EAST OF THE
FORECAST AREA.

SLIGHTLY COOLER TEMPS WILL PREVAIL ON TUESDAY WITH WINDS SLOWLY
BECOMING SOUTHWESTERLY AS THE DAY PROGRESSION. WEAK SHORTWAVE
TROUGH PASSES JUST NORTHWEST OF THE FORECAST AREA ALONG THE
PERIPHERY OF THE MID/UPPER RIDGE WEDNESDAY NIGHT. WENT AHEAD AND
INSERTED SLIGHT CHANCE POP MENTION FROM 06Z-12Z FOR THE POTENTIAL
OF ELEVATED CONVECTION ON THE NOSE OF THE INCREASING H85 LOW LEVEL
JET.

THE HEAT BEGINS TO CRANK UP FROM WEDNESDAY THROUGH THE END OF THE
FORECAST PERIOD ON FRIDAY AS A BROAD MID/UPPER RIDGE REALLY TAKES
HOLD OVER THE CENTRAL CONUS DURING THIS TIME PERIOD. TEMPS COULD
APPROACH OR EXCEED THE 100 DEGREE MARK FOR THE FIRST TIME THIS
YEAR...ESPECIALLY OVER SOUTHERN AND EASTERN PORTIONS OF THE
FORECAST AREA. KEEPING SILENT POPS IN OVER EASTERN COLORADO EACH
AFTERNOON AS A SERIES OF WEAK SHORTWAVE TROUGHS WILL TRANSLATE
THROUGH THE MEAN FLOW.

.AVIATION...
515 PM MDT SAT MAY 28 2011

MOIST...EASTERLY...UPSLOPE FLOW WILL CONTINUE NORTH OF RETREATING
WARM FRONT CURRENTLY LOCATED IN TX/OK. EXPECT WIDESPREAD STRATUS
TO DEVELOP AND MOVE FROM SOUTH TO NORTH OVERNIGHT. KGLD WILL GO
DOWN FIRST...FOLLOWED BY KMCK. IFR CONDS ARE EXPECTED AT BOTH
LOCATIONS DURING THE TAF PERIOD. BY 19Z...KGLD CIG WILL BEGIN TO
LIFT TO MVFR. AT KMCK...EXPECT -RA WITH DEEPER MOIST LAYER...AND
IFR CONDS WILL BEGIN TO WORSEN TOWARD END OF TAF PERIOD...WITH
LIFR CONDS AFT 21Z. TSTORMS ALSO A POSSIBILITY AT BOTH
LOCATIONS OVERNIGHT...HOWEVER...CONFIDENCE IS LOW AT BOTH LOCATIONS GIVEN
STRONG INHIBITION IN PLACE...THUS HAVE OMITTED CB REMARKS IN TAFS.

.FIRE WEATHER...
255 PM MDT SAT MAY 28 2011

BORDERLINE CRITICAL FIRE WEATHER CONDITIONS ARE POSSIBLE SOUTH OF
A LINE FROM WILD HORSE COLORADO TO LEOTI KANSAS ON SUNDAY. GIVEN THE
LOW CONFIDENCE CRITERIA WOULD BE MET...OPTED TO FORGO A HIGHLIGHT.
HOWEVER...GIVEN ANTICIPATED WIND GUSTS OF UP TO 40 MPH ALL BURNING
SHOULD BE AVOIDED.

CRITICAL FIRE WEATHER CONDITIONS ARE LIKELY ALONG AND SOUTH OF A
LINE FROM WILD HORSE COLORADO TO RUSSELL SPRINGS KANSAS ON MONDAY.
RELATIVE HUMIDITY VALUES WILL FALL TO LESS THAN 10 PERCENT WITH
VERY STRONG WINDS OF 30 TO 45 MPH WITH GUSTS TO 60 MPH POSSIBLE.
WHILE CRITICAL FIRE WEATHER CONDITIONS WILL ALSO BE OBSERVED ALONG
THE I-70 CORRIDOR FROM FLAGLER TO COLBY...THESE LOCATIONS RECEIVED
SUBSTANTIAL RAINFALL EARLIER THIS WEEK. THE LOCATIONS WITHIN THE
FIRE WEATHER WATCH RECEIVED MUCH LESS PRECIPITATION OVER THE PAST
FEW WEEKS MAKING FINE FUELS MORE SUSCEPTIBLE TO RAPID FIRE GROWTH.
