AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
337 AM CDT TUE APR 21 2015

.SHORT TERM...(TODAY THROUGH THURSDAY)
ISSUED AT 329 AM CDT TUE APR 21 2015

TODAY-TONIGHT:

ONE AREA OF MID LEVEL LIFT/MOISTURE WILL SCOOT ACROSS SOUTHEAST
KS THIS MORNING...AND ANOTHER CLIPPING OK BORDER. THINKING MAINLY
SPRINKLES GIVEN RELATIVELY DRY LOW LEVELS IN SE KS...WITH SMALL
POPS OVER S CENTRAL KS. SOUNDINGS ROUGHLY EAST OF I-35 PRETTY
MUCH UNCAPPED BY 2100 UTC...WITH VERY RESPECTABLE DEEP LAYER
SHEAR. NOT MUCH FOCUS FOR CONVECTION AND RELATIVELY DRY SOUNDINGS.
WILL KEEP SMALL POPS GOING THROUGH SUNSET FOR A FEW DIURNALLY
ENHANCED SHOWERS/THUNDERSTORMS. A COUPLE OF STRONG STORMS WITH
SMALL HAIL/GUSTY WINDS POSSIBLE GIVEN THERMODYNAMICS...BUT
ORGANIZED SEVERE THREAT LOOKS LOW. THEN AFTER A BRIEF LULL IN THE
EVENING...APPEARS THAT FRONT BACKDOORING ITS WAY ACROSS THE AREA
WILL BRING ANOTHER CHANCE OF PRECIPITATION AFTER MIDNIGHT.
TEMPERATURES TODAY SHOULD WARM NICELY GIVEN DOWNSLOPE FLOW.
TEMPERATURES TONIGHT SHOULD FALL MORE IN THE NORTH WHERE COLD AIR
ADVECTION WILL OCCUR LONGER.

WED-THU:
LOCATION OF BOUNDARY AND ENERGY ALOFT WEST BECOME THE KEY FACTORS
IN FORECAST. A BIT CONCERNED THAT THE CONVECTION ONGOING AT THE
START OF THIS PERIOD COULD FORCE BOUNDARY/PRECIPITATION FURTHER
INTO OK...LEAVING MUCH OF THE AREA DRY LATER ON WED. FOR CONTINUITY/
COLLABORATION...WILL AT LEAST KEEP SMALL POPS GOING WED AFTERNOON
ALONG OK BORDER. CHANCES SHOULD INCREASE WED NIGHT AS LOW LEVEL
FLOW INCREASES...PUSHING DEEPER MOISTURE NORTH. AGAIN NORTHERN
EXTENT OF PRECIPITATION IS A CHALLENGE...AND PREFER THE MORE
SOUTHERN SOLUTION OF ECMWF. PRECIPITATION CHANCES WILL LIKELY
CONTINUE INTO THU...ESPECIALLY ACROSS SOUTHERN/WESTERN EDGES OF
FORECAST AREA WHERE BEST LOW LEVEL BAROCLINICITY/DEEPER MOISTURE
WILL BE LOCATED. MAXIMUM TEMPERATURES WILL BE HIGHLY DEPENDANT ON
AMOUNT OF CLOUDS/PRECIPITATION...SO POTENTIAL FOR LARGE ERRORS IN
THE TEMPERATURE FORECASTS IS HIGH. DO EXPECT SOME/MORE SUNSHINE
IN NORTHERN SECTIONS TO OFFSET POTENTIAL COLD AIR NORTH OF FRONT.

.LONG TERM...(FRIDAY THROUGH MONDAY)
ISSUED AT 329 AM CDT TUE APR 21 2015

MEDIUM RANGE MODELS ARE IN A BIT BETTER AGREEMENT THAN 24 HOURS
AGO...BUT GIVEN THE RUN TO RUN VARIATIONS OF THE LAST 3 RUNS OF THE
ECMWF...NOT VERY CONFIDENT THAT THE CURRENT RUNS ARE REALLY ANY
MORE CORRECT THAN YESTERDAY. THAT SAID...THE CONSISTENCY DOES ALLOW
FOR A BETTER RELATIONSHIP BETWEEN MODEL MASS FIELDS AND INTIALIZATION
GRIDS. THE KEY TAKEAWAYS ARE CHANCES FOR PRECIPITATION STILL LOOK
GOOD FOR FRI/FRI NIGHT WITH WAVE PROBABLY MOVING THROUGH...AND
THEN A BIT DRIER IN THE MIDDLE OF THE WEEKEND. ANOTHER WAVE MAY
BE MOVING THROUGH ON SUN...BUT GIVEN NEAR TERM ISSUES...THIS IS
PRETTY QUESTIONABLE AS WELL. WENT ALONG WITH INITIALIZATION FOR
TEMPERATURES GIVEN THE UNCERTAINTY THIS PERIOD. WILL LIKELY BE A
BIT COOLER WHEN IT DOES RAIN AND WARMER WHEN IT DOES NOT...WITH
CURRENT FORECAST CLOSER TO AN AVERAGE TEMPERATURE THROUGHOUT THE
PERIOD. -HOWERTON

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY NIGHT)
ISSUED AT 1047 PM CDT MON APR 20 2015

WEST/SOUTHWEST WINDS WILL INCREASE SOMEWHAT BY MID/LATE MORNING
TUESDAY. CUMULUS AROUND 5000-7000 FT AGL WILL LIKELY DEVELOP
AGAIN TUESDAY AFTERNOON...DUE TO DAYTIME HEATING. MAY SEE A FEW
SHOWERS/THUNDERSTORMS ACROSS THE REGION BY TUESDAY EVENING...AS A
STRONG COLD FRONT APPROACHES FROM THE NORTH. UNSURE ON COVERAGE
DUE TO MEAGER INSTABILITY...SO LEFT MENTION OUT OF TAFS FOR NOW.
