.SHORT TERM...SURFACE COLD FRONT NOW ON THE MOVE ACROSS WESTERN
MIDDLE TENNESSEE, WITH A BAND OF SHOWERS OCCURRING BETWEEN I-65
AND THE TENNESSEE RIVER. IN ADDITION, THE BACK EDGE OF ANOTHER
BAND OF RAIN WAS SLOWLY WORKING ITS WAY EASTWARD ALONG THE
CUMBERLAND PLATEAU. 

LOOK FOR THE COLD FRONT TO SWEEP ON ACROSS THE REMAINDER OF MIDDLE
TENNESSEE THIS AFTERNOON AND EVENING, USHERING IN SOME COLDER AIR
OVERNIGHT. RAIN MIGHT CHANGE BRIEFLY TO SOME LIGHT SNOW OR
FLURRIES OVER EASTERN AREAS LATE TONIGHT, BUT DON'T EXPECT ANY
ACCUMULATION. 

BROAD UPPER TROUGH REMAINS OVER THE OHIO AND TENNESSEE VALLEYS
INTO THE UPCOMING WEEKEND, WITH SEVERAL CLIPPER TYPE SYSTEMS
DROPPING SOUTHEASTWARD FROM THE PLAINS AND PROVIDING US WITH A
CHANCE FOR SOME QUICK SHOTS OF WINTRY PRECIP (ESPECIALLY ACROSS
NORTHERN AND EASTERN AREAS) LATE TOMORROW AND TOMORROW NIGHT AND
AGAIN SATURDAY AND SATURDAY NIGHT. 

EXPECT A RAIN/SNOW MIX TO TURN BRIEFLY TO ALL SNOW THURSDAY NIGHT,
WITH A DUSTING POSSIBLE (ESPECIALLY ALONG THE HIGHLAND RIM AND
CUMBERLAND PLATEAU). A DECENT SHOT OF REINFORCING COLD AIR COMES
IN BEHIND THIS SHORTWAVE, WITH LOWS BY SUNRISE FRIDAY DROPPING
INTO THE MID TEENS TO LOWER 20S. 

THE NEXT LOW PRESSURE SYSTEM THAT COMES IN ON SATURDAY SHOULD HAVE
SOME DECENT WARMING AHEAD OF IT AND ALLOW FOR A WINTRY MIX TO
DEVELOP. LOOKS LIKE A BETTER CHANCE FOR A BAND OF RAIN AND
FREEZING RAIN WITH THAT PARTICULAR SYSTEM, AS A WARM NOSE WILL
LIKELY FORM IN THE 950-850MB LAYER. 

.LONG TERM...AFTER THE SATURDAY SHORTWAVE PASSES, LOOK FOR INCREASED
ATMOSPHERIC MOISTURE TO WORK ITS WAY NORTHWARD FROM THE WESTERN
GULF OF MEXICO, UP ACROSS THE LOWER AND MIDDLE MISSISSIPPI RIVER
VALLEY SUNDAY NIGHT AND MONDAY, AND THEN FINALLY PULLS EASTWARD
ACROSS OUR AREA MONDAY NIGHT AND TUESDAY ALLOWING FOR AT LEAST A
SLIGHT CHANCE FOR RAIN.

COOL PATTERN MAY GIVE WAY TO SOME MILDER CONDITIONS BY THE MIDDLE
OF NEXT WEEK, AS UPPER TROUGH PULLS EAST AND RIDGING MOVES IN
FROM THE PLAINS.
