Severe Thunderstorm Warning 255, NWS Wichita, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
344 AM CDT SAT JUN 15 2002

CURRENT FORECAST LOOKS TO BE ON TRACK. WATER VAPOR SATELLITE IMAGERY
THIS MORNING INDICATED A JET STREAK MOVING INTO CALIFORNIA AND
NEVADA. AVN AND ETA MODELS BOTH TAKE THIS JET STREAK EASTWARD AND BY
18Z HAVE THE LEADING NOSE OF THIS STREAK INTO SOUTHEASTERN COLORADO.
THIS JET SHOULD ASSIST IN DEEPENING THE SURFACE LOW PRESSURE SYSTEM
IN THAT LOCATION. MORNING DEWPOINTS THROUGH SOUTHEAST COLORADO ARE
IN THE MID AND UPPER 50S AND WITH THE LOW LEVEL JET INTENSIFYING
WITH TIME...THE AIR MASS SHOULD ONLY GET MORE MOIST. SPC HAS MADE
THIS AREA THE FOCUS FOR SEVERE CONVECTION AND CERTAINLY LOOKS TO BE
ON TRACK.

AS CONVECTION DEVELOPS THIS AFTERNOON IT SHOULD TRACK TO THE
SOUTHEAST. MODELS IN AGREEMENT THAT THE JET STREAK SHOULD MOVE
SOUTHEAST TONIGHT AND THROUGH WESTERN OKLAHOMA INTO NORTH TEXAS...SO
THINK THE BEST CHANCES OF PRECIPITATION WILL BE THERE. FOR US...WILL
CERTAINLY BE ON THE EDGE AND THINK OUR WESTERN AND SOUTHERN SECTIONS
HAVE THE BETTER CHANCES OF RAIN. THAT IS WHY THE CHANCE CATEGORIES
THERE AND SLIGHT CHANCE AS YOU GO NORTHEAST.

SUNDAY WE STAY UNDER NORTHWEST FLOW. UNDER THAT TYPE SCENARIO...ANY
BOUNDARY THAT COULD SET-UP FROM THE SYSTEM THAT TRACKS SOUTHEAST
THIS AFTERNOON AND TONIGHT COULD GENERATE SOMETHING. SO WILL
MAINTAIN THE 20% POPS. NORTHWEST FLOW STAYS WITH US INTO MONDAY.

ALL MODELS HOLDING CONSISTENT WITH BREAKING THE WESTERN U.S RIDGE
DOWN BY MID WEEK AND MAKING A MORE TYPICAL SUMMER WEATHER PATTERN.
THAT IS WEATHER SYSTEMS MOVING THROUGH THE NORTHERN STATES AND
SOUTHERN CANADA. ACROSS THE SOUTHERN TIER...DOLD-DRUM HIGH PRESSURE
SYSTEMS AND WE ARE IN THE MIDDLE. UNDER THIS TYPE SYSTEM WE WILL SEE
A LOW PRESSURE TROF ALONG THE LEE SLOPES OF THE ROCKIES WITH
SOUTHERLY FLOW FOR US. AS PER CURRENT FORECAST TEMPERATURES WILL BE
CLIMBING INTO THE UPPER 80S TO LOWER 90S. AS FOR PRECIPITATION
CHANCES...FOR NOW WILL CONTINUE TO LEAVE THE EXTENDED PERIODS
DRY.
