.PREV DISCUSSION... /ISSUED 254 AM CDT THU OCT 30 2014/

DISCUSSION...
CLEAR SKIES WITH TEMPS MOSTLY IN THE 40S TO START THE DAY WITH
SURFACE HIGH CENTERED OVER SOUTHERN ILLINOIS. SURFACE HIGH WILL
SHIFT EAST TODAY AS UPPER TROUGH BROADENS OUT FROM WEST TO EAST. A
SHORT WAVE WILL DIVE QUICKLY SOUTHEAST FROM MIDDLE MISSISSIPPI
VALLEY THIS AFTERNOON AND DOWN THROUGH THE OHIO AND TENNESSEE
VALLEYS TONIGHT. I HAVE PUT A CHANCE FOR LIGHT SHOWERS IN THE
FORECAST FOR TONIGHT MAINLY INTERSTATE 40 NORTHWARD...WITH THE
HIGHER POPS TO OUR NORTH WHERE MOISTURE WILL BE A LITTLE DEEPER
AND MORE LIFT. ON FRIDAY A BOWLING BALL TYPE FEATURE WILL DROP
QUICKLY SOUTHWARD FROM GREAT LAKES REGION AND DOWN THROUGH EASTERN
TENNESSEE FRIDAY NIGHT AND INTO THE CAROLINAS ON SATURDAY. THIS
UPPER LOW WILL BE UNDERGOING CYCLOGENSIS AS IT DIVES SOUTHEASTWARD
THROUGH OUR EASTERN AREAS AND PLATEAU. LOOKS LIKE A GOOD CHANCE
FOR SHOWERS ON FRIDAY ACROSS THE MID STATE WITH SURFACE COLD FRONT
MOVING THROUGH DURING THE DAY. I`VE KEPT HIGHS ON FRIDAY IN THE
50`S BUT FAR SOUTHERN TIER OF COUNTIES MAY TOUCH 60 BRIEFLY BEFORE
FROPA. HALLOWEEN LATE NIGHT GETS INTERESTING FAR EASTERN MIDDLE
TENNESSEE AND PLATEAU...ESPECIALLY UPPER CUMBERLAND AS COLD CORE
CYCLOGENIC UPPER LOW CENTER PASSES JUST EAST OF MY CWA. WITH
SURFACE TEMPS DOWN IN THE LOW 30S EXPECT TO GET REPORTS OF SOME
LIGHT SNOW. COULD SEE A DUSTING IN THAT UPPER CUMBERLAND REGION
LATE FRIDAY NIGHT...ESPECIALLY FENTRESS COUNTY. ELSEWHERE...LOWS
SATURDAY MORNING WILL BE AROUND FREEZING IN MANY AREAS BUT WINDS
WILL STAY UP KEEPING FROST OUT. CHILLY DAY SATURDAY WITH HIGHS IN
THE 40S. COULD SEE A FEW MORNING FLURRIES IN THE UPPER CUMBERLAND
SATURDAY MORNING. WILL LIKELY NEED A FREEZE WARNING SATURDAY
NIGHT/EARLY SUNDAY AS TEMPS WILL BE BELOW FREEZING ACROSS ALL OF
THE MID STATE. UPPER RIDGE BUILDS THIS WAY FROM PLAINS ON SUNDAY
AND WILL DOMNATE UNTIL FRONT APPROACHES MID WEEK BRINGING SHOWERS
TUESDAY NIGHT AND WEDNESDAY. HIGHS IN THE 60S WITH LOWS IN THE 40S
MUCH OF NEXT WEEK.
