NATIONAL WEATHER SERVICE MEMPHIS TN
300 PM CDT SAT MAY 25 2002

A COLD FRONT OVER SE MO AND NRN AR WILL PUSH INTO THE NW PART OF THE
CWFA THIS EVENING AND STALL OVER THE NRN CWFA TNT. EXPECT THIS
BOUNDARY TO WASH OUT ON SUN. SCT TSTMS ARE OCCURRING ACROSS THE CWFA
AND EXPECT THIS ACTIVITY TO CONT WELL INTO THE EVENING. STILL CANNOT
RULE OUT A SHWR/TSTM OVERNIGHT WITH THE FRONT OVER THE AREA. EVEN
THOUGH THE FRONTAL BOUNDARY WILL BE DYING ON SUN...EXPECT SCT TSTMS
FROM LEFTOVER MOISTURE AND INSTABILITY. WILL INCLUDE LINGERING POPS
IN THE S SUN EVENING.

A SUMMER-LIKE PATTERN DEVELOPS THIS COMING WEEK...SO TEMP VARIATIONS
WILL BE MINIMAL AND WINDS WILL BE LIGHTER THAN THE LAST SEVERAL
WEEKS. WEAK RIDGING WILL TAKE PLACE MON-TUE...SO DO NOT EXPECT MUCH
IN THE WAY OF TSTM ACTIVITY. AN UPPER TROUGH APPROACHES THE REGION
FROM THE W WED AND HANGS AROUND THROUGH FRI. SINCE MODELS ARE MORE
AND MORE CONSISTENT WITH THIS SCENARIO...WILL INCLUDE PM TSTM POPS
WED-FRI. A SUBTROPICAL RIDGE DEVELOPS OVER THE REGION NEXT WEEKEND...
SO EXPECT LOWER POPS AND HIGHER TEMPS BY DAY 7.
