Area forecast discussion, May 24, 3:30 AM CDT, 2 hours 53 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 330 AM CDT FRI MAY 24 2002 MAIN CONCERN WITH THIS FORECAST PACKAGE WILL BE THE FLASH FLOOD POTENTIAL THROUGH TONIGHT. LATEST WATER VAPOR LOOP SHOWING TWO LARGE COMPLEXES. THE FIRST ONE WAS LOCATED IN NORTHERN OK WHILE THE SECOND ONE WAS LOCATED IN SOUTH CENTRAL AND SOUTHEAST KS. THE COMPLEX ACROSS SRN KS HAS BEEN BACKBUILDING AND SHOWING VERY LITTLE IF ANY FORWARD PROPOGATION DURING THE NIGHT. MEANHWILE...THE COMPLEX ACROSS OK IS SHOWING A MUCH FASTER FORWARD PROPOGATION. IT APPEARS THE LOW LEVEL JET IS STARTING TO VEER ACCORDING THE LAMONT PROFILER WHICH IS HELPING SPEED UP THE MOVEMENT OF THE COMPLEX IN OK. WOULD EXPECT THE COMPLEX IN SOUTHERN KS TO ALSO FOLLOW SUITE AND PROGRESS THROUGH SE KS THROUGH THE EARLY MORNING HOURS. THIS COMPLEX HAS PRODUCED DOPPLER RAINFALL ESTIMATES ACROSS BUTLER/COWLEY COUNTIES BETWEEN 4 AND 5 INCHES WHICH MATCHES WELL WITH THE COOP OBSERVERS. AS THIS COMPLEX MOVES EAST...I WOULD EXPECT THE COMPLEX TO NOT BACKBUILD AS MUCH DURING THE REMAINDER OF THE MORNING DUE TO THE VEERING OF THE LOW LEVEL JET. AS A RESULT...THESE SHOWERS AND STORMS SHOULD TEND WEAKEN BY MID MORNING. WE WILL HANG ON TO LIKELY POPS DURING THE MORNING IN THE SOUTHEAST WITH MAINLY CHANCE POPS ELSEWHERE. TONIGHT IT APPEARS THE NEXT SHORTWAVE WILL ROTATE IN FROM THE ROCKIES AND BRING ANOTHER ROUND OF SHOWERS AND STORMS. IT APPEARS THERE WILL BE AID AGAIN FROM THE RIGHT ENTRANCE REGION OF THE UPPER LEVEL JET. IT APPEARS THAT THIS WAVE WILL BE MORE PROGRESSIVE THAN TONIGHTS WAVE...BUT THE MODELS ARE TENDING TO SLOW THE PROGRESSION OF THIS WAVE FROM THE PREVIOUS RUN. AS A RESULT...WE ARE KEEPING OUR FFA GOING UNTIL TOMORROW MORNING. SATURDAY WE WILL KEEP A SHOT OF MORNING SHOWERS AND THUNDERSTORMS GOING IN SOUTHEAST KS...BUT THE REST OF THE FORECAST PACKAGE LOOKS GOOD AS HIGH PRESSURE BUILDS IN FROM THE ROCKIES THIS WEEKEND.
