Area forecast discussion, Jul 25, 2:22 PM MDT, 5 hours 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
222 PM MDT MON JUL 25 2005

.DISCUSSION...THE SURFACE PREFRONTAL TROUGH IS ACROSS THE FORECAST
AREA WITH THE MAIN FRONTAL BOUNDARY JUST MOVING INTO THE NORTHWEST
SECTIONS OF THE FORECAST AREA.  THE FRONTAL BOUNDARY IS EXPECTED
TO MOVE ACROSS THE AREA MORE QUICKLY FOLLOWING SUNSET AND WILL BE
ASSISTED BY COOL THUNDERSTORM OUTFLOW FROM STORMS EXPECTED TO
DEVELOP LATER THIS AFTERNOON AND EVENING.

THE FORECAST PROBLEM IS THE AMOUNT OF COOLING BEHIND THE FRONT.
ADDITIONALLY THERE IS A POSSIBILITY OF LOW CLOUDS AND DECREASED
VISIBILITY ALONG WITH THE INCREASE IN RH AND THE UPSLOPE FLOW
EXPECTED EARLY TOMORROW MORNING.

IT IS DIFFICULT TO BELIEVE THE MODEL DATA THAT IS PRODUCING HIGH
TEMPERATURE ON TUESDAY THAT AREA COOLER THAN MOST OF THE LOWS FROM
THE PAST FEW DAYS.  THE GFS IS WARMER THAN THE NAM...BUT IS STILL
TOO COOL.  THE GFS IS ALSO MORE MOIST...BUT HAS A TENDENCY TO
OVER DO THE UPSLOPE PRODUCED PRECIPITATION.  HAVE GENERALLY WITH
THE GFS SOLUTION...BUT HAVE BUMPED UP TEMPERATURES A FEW DEGREES THROUGH
MID WEEK AND HAVE TRIMMED DOWN THE POPS AND QPF.

A SHORT WAVE TROUGH MOVES EAST OF THE ROCKIES AND ACROSS THE HIGH
PLAINS THIS EVENING WITH A SECONDARY SHORT WAVE TROUGH TO MOVE
ACROSS THE REGION LATE TOMORROW.  THE FIRST WAVE WILL HELP SWEEP
THE FRONT ACROSS THE REGION...WHILE THE SECOND WILL SWEEP OUT THE
MOISTURE.  BEHIND THE TROUGHS...THE WEAK RIDGE OVER THE WESTERN
U.S. WILL AMPLIFY AND MOVE EAST OVER THE ROCKIES AND HIGH PLAINS
BY THE WEEKEND.  A WEAK LEE TROUGH WILL DEVELOP LATE IN THE WEEK
ALSO.  THE LEE TROUGH AND STRENGTHENING RIDGE WILL ALLOW
TEMPERATURES TO WARM THROUGH THE LATTER PART OF THE WEEK AND INTO
THE WEEKEND WITH A RETURN OF DRY CONDITIONS AND WARMER THAN NORMAL
TEMPERATURES BY THE BEGINNING OF NEXT WEEK.
