AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
316 PM CDT SUN MAR 29 2015

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 243 PM CDT SUN MAR 29 2015

TONIGHT-MON NIGHT:
AS SURFACE RIDGE MOVES ACROSS THE AREA TONIGHT...ANTICIPATE GOOD
RADIATIONAL COOLING WITH LOW TEMPERATURES NEAR NORMALS. DRY AIR
AND GOOD INSOLATION WILL ALLOW BIG TEMPERATURE REBOUND ON MON...SO
WELL ABOVE NORMAL TEMPERATURE STREAK WILL PERSIST. INCREASING LOW
LEVEL MOISTURE AND RETURN FLOW WILL KEEP TEMPERATURES A BIT WARMER
MON NIGHT.

TUE-TUE NIGHT:
MOISTURE INCREASES ON TUE WITH SMALL CHANCES FOR PRECIPITATION
DEVELOPING LATE IN THE AFTERNOON NEAR OK BORDER. MODEST CAPE WOULD
ALLOW FOR SOME THUNDERSTORMS...BUT WITH LITTLE SURFACE
CONVERGENCE AND ONLY MODEST UPPER LIFT...GOOD CHANCE THAT LIFT
WILL NOT BE ENOUGH TO BREAK CAP. CHANCES WILL EXPAND A BIT AS LOW
LEVEL MOISTURE SPREADS NORTH TUE NIGHT...BUT PATTERN STILL DOES
NOT APPEAR FAVORABLE FOR WIDESPREAD PRECIPITATION.

WED-WED NIGHT:

LACK OF SURFACE CONVERGENCE AND FAIRLY STOUT CAP SHOULD PRECLUDE
CONVECTION FOR MOST OF DAYLIGHT HOURS. FAIRLY BIG DIFFERENCES IN
MODELS ON TIMING OF COLD FRONT POTENTIALLY REACHING FAR NORTHWEST
SECTIONS LATE AFTERNOON. SLOWER TIMING AND DRY DAYLIGHT FORECAST
SEEMS MORE PROBABLE...BUT CONSENSUS FORCED KEEPING A MENTION IN
RUSSELL COUNTY AFTER 2100 UTC. INSTABILITY APPEARS TO BE ON THE
ORDER OF 1000-2000 J/KILOGRAM...WITH 30KTS OF BULK SHEAR...SO IF
SOMETHING DEVELOPS...PROBABILITY OF SEVERE IS PRETTY GOOD EARLY
ON. CHANCE FOR RELEVATED SHOWERS/THUNDERSTORMS INCREASES DURING
THE NIGHT AS THE FRONT PUSHES ACROSS THE AREA. BIGGEST CONCERN
THIS PERIOD IS FIRE WEATHER POTENTIAL  WITH INCREASING
MIXING/SURFACE GRADIENT AND WARMER TEMPERATURES. FIRE WEATHER
SECITON HAS MORE DETAILS. -HOWERTON

.LONG TERM...(THURSDAY THROUGH SUNDAY)
ISSUED AT 243 PM CDT SUN MAR 29 2015

UNCERTAINTY HAS INCREASED THIS PERIOD WITH ECMWF/GFS DIVERGING
EVEN MORE OVER THE PAST TWO RUNS WITH TIMING/DEPTH OF SHORTWAVE
MOVING THROUGH ZONAL FLOW. WHERE/HOW DEEP/WHAT TRACK THIS WAVE AND
ASSOCIATED SURFACE FEATURE WILL TAKE WILL SIGNIFICANTLY IMPACT
PRECIPITATION CHANCES AND TEMPERATURES FOR MUCH OF THIS PERIOD. AT
THIS POINT MADE ONLY MINOR TWEAKS TO INITIALIZATION GRIDS.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1239 PM CDT SUN MAR 29 2015

BREEZY NORTHWEST WINDS WILL DEVELOP ACROSS THE AREA IN THE WAKE OF
A COLD FRONT WITH SPEEDS OF 25 TO 35 MPH COMMON ACROSS CENTRAL
KS. SPEEDS WILL QUICKLY DIMINISH THIS EVENING AS HIGH PRESSURE
SETTLES OVERHEAD WITH CLEAR SKIES AND VARIABLE WINDS ANTICIPATED
OVERNIGHT. BREEZY SOUTHWEST WINDS WILL RETURN TO CENTRAL KANSAS ON
MONDAY AFTERNOON WHILE LIGHT SOUTHERLY WINDS RETURN TO MUCH OF
SOUTHEAST KANSAS.


&&

.FIRE WEATHER...
ISSUED AT 243 PM CDT SUN MAR 29 2015

WINDS WILL DIMINISH THIS EVENING...AND WILL LET RED FLAG WARNING
EXPIRE ON SCHEDULE. ON MON...WINDS WILL BE LIGHTER...WITH ONLY VERY
HIGH GFDI IN CENTRAL AND PARTS OF SOUTH CENTRAL KS. MUCH LIGHTER
WINDS ON TUE WILL FURTHER REDUCE THREAT.

NOTHER POTENTIAL RED FLAG DAY IS IN THE MAKING FOR WED WITH 20+ KT
SUSTAINED WINDS IN THE AFTERNOON AND DRY LOW LEVEL AIRMASS. FORECAST
GFDI ROUGHLY NORTH OF A HUTINSON TO EUREKA LINE IS EXTREME. WILL
HOLD OFF ON HOISTING WATCH UNTIL EVENT GETS CLOSER GIVEN MODEL
UNCERTAINTY. -HOWERTON
