AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
545 PM MDT TUE OCT 21 2014

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 213 PM MDT TUE OCT 21 2014

TONIGHT...

LEE-SIDE TROUGH TO OUR WEST...COMBINED WITH HIGH PRESSURE TO OUR
EAST IS GIVING A NICE WARM AFTERNOON ACROSS THE ENTIRE FORECAST
AREA. THIS COMBINATION IS PROVIDING THE FORECAST AREA WITH STRONG
SSE FLOW...LIFTING TEMPERATURES INTO THE M70S UP TO THE L80S WITH
MSUNNY/SUNNY SKIES. GOING INTO TONIGHT AND THE OVERNIGHT
PERIOD...CWA WILL SEE CONTINUING OF SYNOPTIC SETUP INITIALLY.
EXPECTING AREA TO SEE FAIRLY DECENT NIGHT WITH GRADIENT REMAINING
INITIALLY BUT SLACKENING SOME BY MIDNIGHT. BY MIDNIGHT...MODELS DO
BRING TROUGH SLOWLY OFF THE FRONT RANGE AND INTO THE PLAINS REGION
BY 12Z WEDNESDAY. INCREASING CLOUD COVER WILL ACCOMPANY THE LEADING
EDGE OF APPROACHING TROUGH WITH SOME LIGHT -RW OVER EASTERN COLORADO
BY 12Z WED. QPF ONLY A FEW HUNDREDTHS. BY 08Z WED...NORTHERN AND
CENTRAL KANSAS ZONES WILL SEE CHANCE FOR LIGHT PATCHY FOG DEVELOPING
BEFORE CLOUDS OVERRUN AREA. BASED ON LATEST DEWPTS FROM OBS AND
MODEL GUIDANCE...LOOKING FOR OVERNIGHT LOWS TO RANGE FROM THE U40S
WEST TO THE M50S EAST. THESE NUMBERS WILL DEPEND ON EXTENT/PUSH OF
CLOUD COVER PUSHING INTO AREA TONIGHT.

WEDNESDAY...

EARLY MORNING FOG WILL GIVE WAY TO LEE-SIDE TROUGH AND ASSOCIATED
SFC FRONT TRAVERSING THE CWA FROM WEST TO EAST MID MORNING HRS INTO
THE EARLY EVENING. THIS SYSTEM COMBO WILL BE SLOWED BY BLOCKING
RIDGE OVER THE MISSISSIPPI. WEAK/MODERATE INSTABILITY WILL KICK OFF
SOME ISOLATED THUNDER W/ -RW. BEST CHANCES FOR -TRW ACTIVITY WILL
OCCUR OVER CENTRAL/NORTHERN ZONES...DUE TO MORNING TIMING OVER
WESTERN CWA. LIGHT/MODERATE -RW COULD BRING A RANGE OF 0.02-0.20"
QPF POTENTIAL. EARLY HIGHS EXPECTED FOR WESTERN ZONES...DUE TO WIND
SHIFT WITH SURFACE FROPA... SO BRING THESE LOCALES MID TO UPPER 60S
AND LOW 70S ELSEWHERE.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 213 PM MDT TUE OCT 21 2014

WEDNESDAY EVENING THERE MAY BE SOME LINGERING STORMS MAINLY EAST OF
HIGHWAY 83 AS THE UPPER LEVEL TROUGH DEPARTS THE TRI-STATE AREA.
THOUGHT ABOUT ADDING A MENTION OF FOG OVER THE EAST WHERE THE MOST
RAIN WILL HAVE FALLEN...BUT MODELS INDICATE THE REDUCED VISIBILITIES
WILL BE EAST OF THE AREA.  SO WILL LEAVE A MENTION OF FOG OUT OF THE
FORECAST AT THIS TIME.

THURSDAY THROUGH SUNDAY WILL REMAIN DRY AS THE UPPER LEVEL RIDGE
BUILDS BACK OVER THE AREA.  TEMPERATURES WILL CONTINUE TO BE ABOVE
NORMAL UNDER THE RIDGE.

THE NEXT ROUND OF RAINFALL WILL BE SUNDAY NIGHT AND MONDAY AS AN
UPPER LEVEL TROUGH MOVES ACROSS THE NORTHERN PART OF THE AREA.  AT
THIS TIME MODELS DISAGREE HOW FAST THE TROUGH WILL MOVE THROUGH AND
HOW FAR SOUTH THE TROUGH WILL BE AS IT MOVES ACROSS THE AREA.  THE
FURTHER SOUTH THE TROUGH WILL BE THE BETTER THE RAINFALL CHANCES
WILL BE FOR THE AREA.  A COLD FRONT WILL ACCOMPANY THE TROUGH
THROUGH THE AREA MONDAY.  BEHIND THE FRONT HIGHS WILL BE NEAR
NORMAL.
