NATIONAL WEATHER SERVICE WICHITA KS
320 AM CDT SAT MAY 23 2015

.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 302 AM CDT SAT MAY 23 2015

TODAY-TONIGHT:
EXTENSIVE CLOUDS/PRECIPITATION ANTICIPATED WITH MOISTURE IN
PLACE...INCREASING DIFFLUENCE AHEAD OF APPROACHING UPPER
JET...AND DECENT WARM AIR ADVECTION AT TIMES. APPEARS THAT EARLY
IN PERIOD...BULK OF RAIN WILL BE ACROSS SOUTHERN KS...THEN
SHIFTING NORTH DURING THE DAY. RENEWED CONVECTION ANTICIPATED
TONIGHT ACROSS SOUTHEAST KS AS PERSISTENT UPPER DIFFLUENCE/LOW
LEVEL JET PARKS OVER THAT AREA. FLASH FLOOD WATCH STILL LOOKS VERY
GOOD IN SOUTHEAST KS...WHERE SIGNIFICANT AREAL AND RIVER FLOODING
IS POSSIBLE. THREAT IN WESTERN EDGES OF WATCH APPEARS FAVOR SHORT
TERM ISSUES WITH DUE TO EXCESSIVE RUNOFF. WILL NOT BE MAKING ANY
CHANGES TO GOING WATCH.

SUN-SUN NIGHT:
SUN MORNING WILL LIKELY SEE A CONTUATION OF PRECIPITATION FROM
SAT NIGHT ACROSS SOUTHEAST KS . SOME BREAKS POSSIBLE IN THE
WESTERN HALF...ESPECIALLY IN THE MORNING...BUT HEATING WILL LIKELY
RENEW CONVECTON IN THE AFTERNOON. ANOTHER PIECE OF ENERGY WILL
LIKELY TRAVERSE THE AREA SUN AFTERNOON/EARLY EVENING. FOCUS AGAIN
APPEARS TO BE AREA EAST OF I-35.

MON:
THIS IN ONE THE MOST CHALLENGING PERIODS OF THE FORECAST. MODELS
SUGGEST PRECIPITATION WILL WANE IN WAKE OF DEPARTING SHORTWAVE.
CONSIDERABLE MOISTURE WILL REMAIN IN PLACE. MODELS CONTINUE TO
SHOW INSTABILITY SOARING / 3000+ J/KG / WITH HEATING...BUT ONLY
25-30KTS OF DEEP LAYER SHEAR AND LITTLE CAP. GIVEN LACK OF OBVIOUS
SURFACE BOUNDARY...ANTICIPATE MORE SUMMER-LIKE STORMS TO DEVELOP
FAIRLY EARLY IN THE AFTERNOON AND PERSIST INTO MON EVENING.
LOCALLY HEAVY RAIN...WITH LOW END HAIL AND MICROBURSTS LOOK TO BE
MAIN THREATS. -HOWERTON

.LONG TERM...(TUESDAY THROUGH FRIDAY)

SHORTWAVE EXITS AREA AT START OF PERIOD...WHILE WESTERN TROUGH
RELOADS. SUBSIDENCE IN WAKE OF SHORTWAVE SHOULD SUPPRESS
CONVECTION AND ALLOW AREA TO DRY OUT A BIT. INITIALIZATION GRIDS
HAVE LOW POPS NEARLY ALL PERIODS...AND GIVEN UNCERTAINTY IN
TRANSITION OF UPPER PATTERN...HARD PRESSED TO GO AGAINST IT. LACK
OF WELL DEFINED SURFACE BOUNDARY THROUGHOUT PERIOD FUTHER
COMPLICATES CONVECTION FORECAST. TEMPERATURES EQUALLY QUESTIONABLE
GIVEN UNCERTAIN CLOUD/PRECIPITATION FORECAST. INITIALIZATION BLEND
LIKELY THE LEAST WRONG...WITH SOME DAYS IN THE PERIOD BEING
WARMER/SOME COOLER THAN INIT...MODULATED BY AMOUNT OF CONVECTION.
