FCST FOCUS REMAINS TEMPS AND PRECIP CHCS IN HYBRID ZONAL/NW FLOW

WILL USE A BLEND OF ETA LOW LEVEL PRESSURE/DEWPOINT FCSTS WITH BLEND
OF ALL MODELS FOR PRECIP DEPICTIONS.

LATEST WATER VAPOR SHOWS MAIN CORRIDOR OF WESTERLIES ACROSS
NEB...IA...INTO N IL/WI...WITH STRONG SHORT WAVE RACING INTO THE
DAKOTAS.  PRESSURE FALLS ACROSS THE PLAINS IN ADVANCE OF THIS SYSTEM
ARE ALLOWING SFC WINDS TO SLOWLY VEER TO THE SOUTH ACROSS THE AREA.
MEANWHILE...KS REMAINS IN MOIST SUBTROPICAL FETCH WITH WEAK VORTS
ROTATING AROUND WEAKNESS IN UPPER RIDGE. MOST OBVIOUS OF THESE NOW
ACROSS EASTERN NM. AT 500 MB SMALL COLD POOL OF -10C INDICATED
ACROSS WESTERN KS. AT 700 MB PROFILERS SHOW 20KTS OF SSW FLOW WITH
NEUTRAL ADVECTION WITH STRONG MOISTURE ADVECTION INTO THE CWA.
MEANWHILE...AT 850 MB EAST-WEST AXIS OF +15C DEWPOINTS EXTENDED FROM
DDC INTO SW MO. CURRENT SFC MAP SHOWS THREE DISTINCT BOUNDARIES WITH
THE FIRST ACROSS SOUTH-CENTRAL KS SEPARATING SSE FLOW FROM SSW FLOW
WITH LOW 70 TDS JUST NORTH OF THIS WEAK BOUNDARY SLIGHTLY ELEVATED
STORMS SEEM TO BE INITIALLY DEVELOPING ALONG THIS BOUNDARY AND
MOVING NE.  ANOTHER SFC BOUNDARY WAS LOCATED FROM NEAR SLN EAST
ACROSS TOP/MKC WHERE MID 70 TDS ARE POOLING.  MEANWHILE...LATEST VIS
SAT PICS SHOW SFC BASED CU DEVELOPING ACROSS MUCH OF WESTERN OK IN
RELATIVELY MOIST MIXED LAYER.

BASED UPON WHAT IS HAPPENING AT THIS TIME AND THE COMBINATION OF
SHEARED VORT AXIS ALONG WITH CONTINUED INSTABILITY AT THE SFC THIS
EVENING AND ABOVE 800 MB OVERNIGHT WILL UP POPS FOR SOUTHERN KS WITH
JUST THE SLIGHTEST CHCS CENTRAL KS THIS EVENING.  WILL KEEP POPS FOR SOUTH
CENTRAL AND SOUTHEAST TOMORROW WITH MID LEVEL MOIST PLUME AND WEAK
VORT AXIS STILL IN PLACE ALONG WITH MID LEVEL TEMPS OF LESS THAN
12C. LOOKING AT 850 THERMAL AXIS AND FCST 1000-850 THICKNESSES FEEL
THAT WARMEST TEMPS WILL RE-ORGANIZE ACROSS CENTRAL KS TOMMORROW WITH
NGM GUIDANCE LOOKING LIKE IT WILL VERIFY WITHIN 3 DEGREES. BY
TOMORROW NIGHT NORTHERN PLAINS SYSTEM WILL DRAG SFC TROUGH TOWARD
NORTHERN/NW KS. CONVECTIVE TEMPS LIKELY WILL BE REACHED HOWEVER
AREAL COVERAGE REMAINS IN QUESTION AND WILL LEAVE GOING FCST DRY FOR
NOW...WITH BETTER CHC TO FOCUS IN ON THIS AREA TONIGHT AND TOMORROW.

BY WEDS...UPPER RIDGE WILL AGAIN TRY TO AMPLIFY ACROSS THE ROCKIES
LEAVING KS IN TRANSITIONAL UPPER FLOW WHICH WILL BECOME SOMEWHAT
NORTHWESTERLY.  ANY STORM CHCS FOR THE AREA SHOULD THEN SHIFT TO AN
EVENING/OVERNIGHT PATTERN WITH A BOUNDARY NEAR KS/NEB BORDER.
HOWEVER AS USUAL THIS TIME OF YEAR CONFIDENCE IN EXACT EVOLUTION OF
ANY STORMS IS LOW AND CURRENT FCST WILL REMAIN DRY FOR THIS REASON
WITH AMPLE OPPORTUNITY TO INSERT STORMS NEXT 24 HOURS IF NEEDED.  AS
FOR TEMPS THERMAL RIDGE REMAINS PERSISTENT IN LOCATION WITH HOTTEST
TEMPS LIKELY ACROSS CENTRAL KS...AS LONG AS BOUNDARY REMAINS NORTH
OF AREA...WITH AROUND 100 OR SO SOUTH CENTRAL...MID 90S SE.

EXTENDED...UPPER RIDGE ACROSS THE ROCKIES WITH WEAK NW FLOW
ADVERTISED BY MRF WITH DRIER AND WARMER FCST INDICATED BY THE EURO
MODEL. WILL FOLLOW HPC/S LEAD AND GO WITH MRF IDEA OF WEAK BOUNDARY
SAGGING INTO THE AREA THURS/FRI TIME FRAME.  WILL TWEAK TEMPS DOWN
SLIGHTLY SAT AND WAIT ONE MORE DAY BEFORE INSERTING POPS.
