AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
159 AM CST FRI JAN 30 2015

.DISCUSSION...A MUCH COLDER AIR MASS IS IN PLACE THAN 24 HRS AGO,
WITH STRONG HIGH PRESSURE OVER THE UPPER MIDWEST BUILDING INTO
MIDDLE TENNESSEE. LINGERING LOW CLOUDS CONTINUE TO PLAGUE THE MID
STATE, WITH NAM MODEL SOUNDINGS NOT SHOWING ANY CLEARING UNTIL
EARLY AFTERNOON. SURFACE RIDGE WILL MOVE ACROSS THE MID STATE
SATURDAY MORNING AS MID AND HIGH CLOUDS INCREASE AHEAD OF THE NEXT
ACTIVE WEATHER SYSTEM. BY SUNDAY MORNING, AN INVERTED TROUGH WILL
HAVE DEVELOPED WEST OF THE MISSISSIPPI VALLEY. AS IS TYPICALLY THE
CASE WITH SUCH PATTERNS, THERE WILL BE COPIOUS ISENTROPIC LIFT
OVER MIDDLE TENNESSEE AHEAD OF THE SURFACE TROUGH, WITH REASONABLY
HIGH QPF (1/2 TO 3/4 INCH) FROM 12Z SUNDAY THROUGH 06Z MONDAY. BY
00Z MONDAY, A CLOSED SURFACE LOW WILL HAVE DEVELOPED OVER CENTRAL
KY WITH THE UPPER TROUGH STILL WELL TO OUR WEST. COLD ADVECTION ON
THE BACK SIDE OF THIS LOW WILL SEND TEMPERATURES BELOW FREEZING
SUNDAY NIGHT, AND WITH IT COMES OUR NEXT CHANCE OF SNOW. THE BEST
CHANCE WOULD COME AFTER 06Z MONDAY, AND BY THEN THE DEEPEST
MOISTURE WILL HAVE PULLED EAST OF THE MID STATE, BUT IT IS
REASONABLE TO EXPECT SOME ACCUMULATION OF SNOW BY EARLY MONDAY
MORNING, ESPECIALLY OVER AREAS EAST OF NASHVILLE.
