PREV DISCUSSION.../ISSUED 226 PM CDT WED SEP 2 2015/

DISCUSSION...
SLUGGISH PATTERN CONTINUES AS MOISTURE REMAINS OUT OF THE WESTERN
GULF REGION INTO TENNESSEE BUT STRONG SUBSIDENCE IN THE LOWER
TROPOSPHERE IS SUPPRESSING DEEPENING MOISTURE AND LIFT NECESSARY
FOR CONVECTION TO DEVELOP. I DO SEE A FEW SHORTWAVES THAT WILL
ROTATE ACROSS OUR AREA NEXT COUPLE OF DAYS BUT MAY DO NOTHING TO
BRING ABOUT CONVECTION WITH SO MUCH SUBSIDENCE IN LOWER LEVELS. SO
LOOK FOR BASICALLY A DRY FORECAST AT LEAST UNTIL THIS WEEKEND WHEN
MOISTURE FINALLY DEEPENS ENOUGH FOR SCATTERED CONVECTION OVER
EASTERN AREAS AND PLATEAU. DRY WEATHER GOOD PART OF NEXT WEEK BUT
SYSTEM FINALLY APPROACHES FROM THE WEST BY THE MIDDLE TO LATTER
PART OF THE WEEK WITH A BETTER CHANCE FOR RAIN. TEMPS WILL STAY
WARM AND ABOVE CLIMATOLOGY FOR THE NEXT SEVEN DAYS.
