Severe Thunderstorm Warning 183, NWS Nashville, TN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
827 PM CST SAT DEC 27 2008

.UPDATE...IT WAS MOSTLY CLOUDY, BREEZY AND MILD ACROSS THE MID
STATE THIS EVENING WITH TEMPERATURES RANGING FROM THE UPPER 50S
ALONG THE CUMBERLAND PLATEAU TO NEAR 70 ALONG THE TENNESSEE RIVER.
A NARROW BAND OF HEAVY SHOWERS AND ISOLATED THUNDERSTORMS
CONTINUED TO SURGE EASTWARD AT 35 TO 40 MPH ACROSS WESTERN
TENNESSEE. AT 02Z THE BAND OF SHOWERS AND STORMS WAS LOCATED JUST
WEST OF STEWART COUNTY.

SOUTH WINDS WERE MAINLY IN THE 15 TO 25 MPH RANGE THIS EVENING,
WITH SOME HIGHER GUSTS TO AROUND 35. IF WINDS CONTINUE AT THIS
LEVEL, WILL ALLOW WIND ADVISORY TO EXPIRE AT MIDNIGHT.

HEAVIEST SHOWERS AND THUNDERSTORMS ARE OCCURRING ALONG A PRE-
FRONTAL TROUGH, AND AT 02Z THE COLD FRONT WAS STILL BACK OVER
EASTERN ARKANSAS, WITH SCATTERED TO NUMEROUS SHOWERS OCCURRING IN
A BROAD BAND BETWEEN THE COLD FRONT AND THE NARROW BAND OF SHOWERS
AND STORMS ALONG PRE-FRONTAL TROUGH.

IT NOW LOOKS LIKE THE COLD FRONT WILL REACH THE NASHVILLE AREA BETWEEN
07Z AND 08Z AND CROSSVILLE AROUND 11Z. HAVE TEMPERED OVERNIGHT
COOLING A BIT, BASED ON SLOWER FRONTAL MOVEMENT, ESPECIALLY EAST.

STILL WOULDNT BE SURPRISED TO SEE A FEW STRONG-TO-SEVERE
THUNDERSTORMS IN THE MID STATE OVERNIGHT, ALONG WITH PONDING OF
WATER DUE TO BRIEF HEAVY DOWNPOURS. BRIEF WIND GUSTS OF 45 MPH TO
60 MPH COULD OCCUR WITH THE STRONGEST STORMS, ALONG WITH AROUND
3/4 INCH OF RAIN IN ONLY A BRIEF PERIOD OF TIME. LOCAL STORM
REPORTS FROM MEMPHIS INDICATE ISOLATED WIND GUSTS ESTIMATED AT 60
MPH, ALONG WITH SOME DOWNED TREES AND POWER LINES, AS THE STORMS
ROLLED THROUGH THEIR AREA EARLIER THIS EVENING.
