.DISCUSSION...
A COMPLEX PATTERN CONTINUES ACROSS THIS PORTION OF THE NORTHERN 
HEMISPHERE. UPPER RIDGING REMAINED OFF OF THE CALIFORNIA COAST. THE 
ANTICYCLONIC FLOW AROUND THIS HIGH WAS HELPING TO CARVE OUT RATHER 
DEEP TROUGHING OVER THE NORTH AMERICAN DOMAIN...WTIH A FEW UPPER 
LOWS/DISTURBANCES NOTED. ONE WAS MOVING OVER THE MIDDLE MISSISSIPPI 
VALLEY...WITH A NEWER LOW DEVELOPING OVER NE TEXAS. THESE SYSTEMS 
WERE IN A WAY NOTING THE BEGINNING OF A COOL CHANGE IN THE WORKS FOR 
THIS AREA OVER THE NEXT FEW DAYS. A LARGE PLUME OF SUBTROPICAL 
MOISTURE CONTINUED FROM SE OF HAWAII TO ACROSS MEXICO...THE NW GULF 
OF MEXICO AND THE MID ATLANTIC/SE COAST. AS USUAL...THE HEAVIEST 
RAIN HAS REMAINED MOSTLY SOUTH OF THE TENNESSEE VALLEY...GENERALLY 
COINCIDING MORE WITH THE SUBTROPICAL MOISTURE AXIS AND BETTER LOWER 
LEVEL MOISTURE CONVERGENCE.
A TOUGH FORECAST ON THE WHEN/WHERE OF SHOWER ACTIVITY FOR TODAY. 
OUTPUT FROM THE NGM/NAM/GFS ARE IN GENERAL AGREEMENT THAT OUR 
EASTERN AREAS HAVE THE BEST ODDS OF RECEIVING MEASURABLE RAINS... 
ESPECIALLY CONSIDERING THE BEST FORCING WILL TAKE PLACE THERE. 
HOWEVER THE UPPER LOW NOTED OVER NE TEXAS AND RECENT RADAR RETURNS 
WAS SHOWING A BAND OF SHOWERS EXTENDING ACROSS EASTERN MISSISSIPPI 
APPROACHING WESTERN ALABAMA. THIS SHOULD PROVIDE AN EARLY START OF 
RAIN FOR OUR WESTERN AREAS TODAY. THE REMAINDER OF THE VALLEY WILL 
RECEIVE MEASURABLE RAINFALL LATER TODAY. IN THE MEANWHILE...A COLD 
FRONT WILL MOVE ACROSS THE AREA TODAY. HIGH TEMPERATURES THIS 
MORNING WILL PROBABLY NOT RISE VERY MUCH LATER TODAY...WILL MORE 
LIKELY FALL DURING THE AFTERNOON HOURS AS COLD AIR REALLY BEGINS TO 
MOVE IN.
TONIGHT AND MONDAY...A CHANGE OVER FROM RAIN TO SNOW WILL PROBABLY 
HAPPEN DURING THE LATE NIGHT HOURS. HOWEVER WITH A WARM GROUND... 
WELL ABOVE FREEZING AM NOT EXPECTING WINTER WEATHER ISSUES THIS GO 
AROUND. BY DAYBREAK MONDAY WITH OVERNIGHT LOW TEMPERATURES NEARING 
THE FREEZING POINT A LIGHT DUSTING OF SNOW IS POSSIBLE OVER THE 
HIGHER ELEVATIONS OF FRANKLIN COUNTY TENNESSEE. WITH THIS FIRST SNOW 
OF THE SEASON...WILL RELEASE A SPECIAL WEATHER STATEMENT ON THIS. 
LIGHT SNOW SHOWERS SHOULD CONTINUE ON/OFF (MORE OFF THAN ON) DURING 
MONDAY...WITH HIGH TEMPERATURES STRUGGLING TO AROUND THE 40F...WAY 
BELOW SEASONAL NORMS OF AROUND 56. HAVE MAINTAINED A LIGHT DUSTING 
IN THE GRIDS FOR THE HIGHEST ELEVATIONS OF FRANKLIN COUNTY TN. A FEW 
FLURRIES OVER MIDDLE TENNESSEE MONDAY EVENING SHOULD END BY LATE 
MONDAY EVENING...WITH CLOUDS FINALLY FADING AWAY. THIS WILL HELP TO 
MAKE FOR A CHILLY MONDAY NIGHT/TUESDAY MORNING WITH FREEZING 
TEMPERATURES IN THE UPPER 20S AREA WIDE.
A BRIEF DRY DAY IS IN THE WORKS FOR TUESDAY. HOWEVER IT WILL REMAIN 
COLD WITH HIGH TEMPERATURES ONLY IN THE UPPER 40S. IN A PROGRESSIVE 
PATTERN...ANOTHER SYSTEM NEARING FROM THE WEST WILL BRING MORE 
CLOUDS AND MORE CHANCES OF RAIN TO THE FORECAST FOR THE MIDDLE OF 
THIS WEEK. DRY WEATHER RETURNS FOR LATE THURSDAY AND SHOULD LAST 
INTO THE WEEKEND. DAILY HIGH/LOW TEMPERATURES FOR THIS PERIOD WILL 
REMAIN BELOW SEASONAL NORMS.
