AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
405 PM CST FRI NOV 21 2014

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 358 PM CST FRI NOV 21 2014

TONIGHT:
BASED ON COMBO RAP/WRF BOUNDARY LAYER RELATIVE HUMIDITY AND
OBSERVATIONS...HAVE EXTENDED ADVISORY THROUGH 0600 UTC. KEY TO
FORECAST WILL BE VEERING IN BOUNDARY LAYER WINDS WHICH SHOULD
ADVECT SLIGHTLY DRIER AIR WITH DOWNSLOPE COMPONENT INTO THE AREA.
THIS SHOULD ERODE/DISSIPATE FOG AS IT SPREADS EAST ACROSS THE
AREA. AREAS WEST/SOUTHWEST OF ICT SHOULD CLEAR FIRST...BUT MODELS
SUGGEST SWATH ALONG SPINE OF FLINT HILLS MAY PERSIST PAST 0600
UTC. EVENING CREW SHOULD BE ABLE TO ADJUST ADVISORY BY MID EVENING
TO CANCEL/EXPAND AREAS. SOME POSSIBILITY THAT FOG COULD EXPAND
SOUTH ACROSS SOUTHEAST KS IN PERSISTENT SATURATED UPSLOPE
FLOW...AS BOUNDARY LAYER WINDS WILL LIKELY NOT SIGNIFICANTLY VEER
THERE UNTIL CLOSER TO DAYBREAK. VERY MODEST CAPE DEVELOPS LATE
TONIGHT ALONG OK BORDER...AND WILL KEEP MENTION OF THUNDERSTORMS
IN FORECAST THERE.

SAT-SUN:
WITH INCREASING UPPER SUPPORT WILL KEEP FAIRLY HIGH PROBABILITY
OF DRIZZLE/RAIN SHOWER MAINLY EAST OF I-35 ON SAT. EXTENSIVE
CLOUDS WILL SUPPRESS DIURNAL RANGE FOR MUCH OF THE AREA. SOME
CLEARING POSSIBLE IN EXTREME NORTHWEST SECTIONS ON SAT. FRONT
MOVES THROUGH ON SUN WITH GUSTY NORTHWEST WINDS...AND POTENTIALLY
FALLING AFTERNOON TEMPERATURES GIVEN EXTENSIVE CLOUDS.

SUN NIGHT-MON:
PRECIPITATION CHANCES WILL END SUN NIGHT ACROSS SOUTHEAST
KS...WITH CONSIDERABLE CLEARING SUN NIGHT/EARLY MON. CYCLONIC LOW
LEVEL FLOW MAY SPREAD EXTENSIVE LOW CLOUDS BACK SOUTHWEST...PROBABLY
COVERING THE NE HALF OF THE AREA. -HOWERTON

.LONG TERM...(TUESDAY THROUGH FRIDAY)
ISSUED AT 358 PM CST FRI NOV 21 2014

RELATIVELY QUIET WEATHER ANTICIPATED THIS PERIOD. WHILE GFS/ECMWF
ARE FAIRLY SIMILAR...CHALLENGES OF RELATIVELY DRY AIRMASS AND
DOWNSLOPE FLOW FOR AT LEAST PART OF THE PERIOD...COULD MAKE
TEMPERATURES A CHALLENGE. APPEARS THAT COOLER AIR WOULD OVERSPREAD
THE AREA ON WED...WITH POSSIBLE FALLING TEMPERATURES WED
AFTERNOON. RETURN FLOW DEVELOPS ON FRI...AND COULD SEE TEMPERATURES
ARE EVEN WARMER THAN CURRENTLY FORECAST. -HOWERTON

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SATURDAY AFTERNOON)
ISSUED AT 1140 AM CST FRI NOV 21 2014

FOR ICT-SLN-HUT-CNU-RSL...WIDESPREAD IFR TO LIFR CIGS/VSBYS WILL
IMPACT THE REGION THROUGH AT LEAST THIS EVENING...AND POSSIBLY
THROUGH TONIGHT AS WELL...AS RELATIVELY WARM/MOIST LOW-LEVEL AIR
APPROACHES FROM THE SOUTH. THINKING THE LOWEST CIGS/VSBYS WILL BE
AT ICT-HUT. AREAS OF DRIZZLE WILL PREVAIL AS WELL ACROSS MUCH OF
THE AREA. CIGS/VSBYS MAY TEND TO IMPROVE BY LATER TONIGHT...AS
LOW-LEVEL FLOW TURNS MORE SOUTHWESTERLY. HOWEVER...CONFIDENCE IN
THIS SCENARIO REMAINS LOW...SO HELD ONTO THE LOW CIGS/VSBYS
THROUGH THE NIGHT FOR ALL AREAS EXCEPT RSL.
