Hail and Damaging Winds in Kansas, July 31, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
221 PM CDT THU JUL 31 2003

DAYS 1-2...

MAIN FORECAST CONCERNS WILL BE TSTORM CHANCES TONIGHT THRU FRIDAY
AND TEMPERATURES ON FRIDAY.

CONVECTIVE COMPLEX NOW MOVING THRU NORTHWEST MO, NORTHEAST KS, AND
EASTERN IA HAS LEFT AN OUTFLOW BOUNDARY FROM NEAR CONCORDIA TO EAST
OF SALINA. STORMS HAVE DEVELOPED ALONG THE BOUNDARY OVER NORTH
CENTRAL AND NORTHEAST KS AND WILL MISS OUR AREA TO THE EAST. A CU
FIELD DEVELOPED NEAR A SURFACE LOW NORTH OF HLC AND THIS ACTIVITY
IS DEVELOPING RAPIDLY AND MAY CLIP OUR NORTHEAST ZONES. WITH THE
AMOUNT OF INSTABILITY AVAILABLE, STORMS HAVE BECOME SEVERE WITH
HAIL AND WINDS THE PRIMARY THREATS.

STORMS ARE EXPECTED TO CONTINUE TO BACKBUILD ALONG A FRONT WHICH
STRETCHES FROM NORTHEAST CO INTO SOUTHEAST NE WITH SOME HELP FROM A
WEAK SHORTWAVE MOVING OUT OF WY. ALL OF THIS ACTIVITY WILL LIKELY
MERGE INTO ONE OR MORE MCSS WHICH ARE EXPECTED TO MOVE SOUTHEAST
OVERNIGHT. WILL CONTINUE WITH THE HIGHEST POPS NORTHEAST TO LOWEST
POPS SOUTHWEST FOR TONIGHT.

THE FRONT IS EXPECTED TO DROP SOUTH INTO OUR NECK OF THE WOODS
TOMORROW BUT ITS EXACT POSITION IS UP IN THE AIR AS IT WILL BE
AFFECTED BY ANY TSTORM ACTIVITY TONIGHT. THIS MAKES THE PRECIP AND
TEMP FORECAST FOR TOMORROW TRICKY. IF THE FRONT HANGS UP IN THE
CWA, TEMPS COULD REACH THE CENTURY MARK OR HIGHER ACROSS THE SOUTH.
FOR NOW, WILL GO WITH A FRONTAL POSITION SOMEWHERE ACROSS THE
CENTRAL AND SOUTHERN PORTION OF THE AREA DURING THE AFTERNOON AND
WILL BASE POPS AND TEMPERATURES ON THAT. WILL GO LOW 90S NORTH TO
UPPER 90S SOUTHEAST AS A GOOD MIDDLE GROUND. CONVECTIVE DEBRIS AND
FRONTAL POSITION WILL AFFECT THIS FORECAST, SO CONFIDENCE IS LOW
DUE TO THE UNCERTAINTY.

FOR SATURDAY, LOOKS FAIRLY TRANQUIL FOR MUCH OF THE DAY ACROSS THE
AREA NORTH OF THE FRONT AND IN THE SUBSIDENCE REGION OF THE UPPER
JET. TEMPS SHOULD BE IN THE UPPER 80S TO LOWER 90S ACROSS THE CWA.

DAYS 3-7...

DID NOT ADJUST GOING GRIDS MUCH.  MODELS CONTINUE TO SHOW GOOD
NORTHWEST FLOW REGIME THROUGH THE WEEKEND.  NUMEROUS S/WS EVIDENT
ON SATELLITE IMAGES. THINK THERE WILL BE A POSSIBILITY OF
EVENING AND OVERNIGHT TSRA AT LEAST THROUGH TUESDAY.
