AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1104 PM CDT TUE MAR 26 2013

.UPDATE...FOR 06Z AVIATION FORECAST

&&

.AVIATION...
BACK EDGE OF CLOUDS APPROACHING INTERSTATE 65 AT 04Z. CLARKSVILLE
SHOULD SCATTER OUT OR CLEAR SHORTLY WITH NASHVILLE DOING THE SAME
AROUND 05Z. THERE HAVE BEEN SOME BREAKS OVER THE UPPER CUMBERLAND
PLATEAU NORTHWARD INTO KENTUCKY SO AM THINKING THIS TREND WILL
LIKELY CONTINUE IN SPITE OF 50 KNOT SPEED MAX CURRENTLY DROPPING
DOWN THROUGH SOUTHWEST INDIANA AND THROUGH SOUTH CENTRAL KENTUCKY.
HOWEVER THERE IS A SOUTHWARD COMPONENT TO THE CLOUDS NORTH OF THE
OHIO RIVER SO CLOUDS MAY TRY TO MOVE BACK DOWN FROM THE NORTH
CROSSVILLE NORTHWARD LATER TONIGHT.

UPDATE...FOR 00Z AVIATION FORECAST

AVIATION...
LOWER AND MID LEVEL RIDGE WILL BUILD UP THROUGH THE MISSISSIPPI
VALLEY TONIGHT AND WEDNESDAY. STILL SEEING SOME FLURRIES MAINLY
ACROSS THE PLATEAU.

AM EXPECTING GENERALLY VFR CONDITIONS NEXT 24 HOURS BUT CEILINGS
AT CROSSVILLE COULD LOWER INTO MVFR OVERNIGHT.

GOOD FLYING WEATHER ON WEDNESDAY WITH LIGHT WINDS ON LANDINGS AND
TAKEOFF.

PREV DISCUSSION... /ISSUED 620 PM CDT TUE MAR 26 2013/ 

UPDATE...
SENDING A QUICK UPDATE TO THE GRIDS/ZONES TO REMOVE AFTERNOON
WORDING AND SCALE BACK SNOW CHANCES TO JUST FLURRIES OVERNIGHT.
UPDATE OUT SHORTLY.

PREV DISCUSSION... /ISSUED 353 PM CDT TUE MAR 26 2013/ 

SHORT TERM...STILL SOME FLURRIES FLYING OVER PARTS OF THE MID
STATE. HOWEVER, TEMPERATURES HAVE WARMED INTO THE MIDDLE AND UPPER
30S AT MOST LOCATIONS, WITH FREEZING TEMPS CONFINED MAINLY TO THE
HIGHER ELEVATIONS IN THE EAST. 

LOW LEVEL MOISTURE WILL BE SLOW TO CLEAR TONIGHT. HOWEVER, BY
MIDNIGHT, BELIEVE SKIES WILL BE GOING PARTLY CLOUDY OVER THE WEST.
1000-850MB MOISTURE REMAINS ENTRENCHED OVER ABOUT THE NORTHEASTERN
HALF OF OUR FORECAST AREA ON WEDNESDAY, PRODUCING VARIABLE AMOUNTS
OF STRATOCU. HIGHS TOMORROW ARE ONLY EXPECTED TO BE IN THE 40S
OVER NORTHERN AND EASTERN AREAS, RANGING TO THE LOWER AND MIDDLE
50S SOUTHWEST. 

DIRTY NORTHWEST FLOW SENDS VARIABLE AMOUNTS OF MID AND HIGH
CLOUDINESS ACROSS OUR AREA WEDNESDAY AND THURSDAY AND BELIEVE
CLOUDS WILL HELP KEEP TEMPS ON THURSDAY FROM GETTING OUT OF THE
50S AT MOST LOCATIONS EXCEPT, PERHAPS, NEAR THE ALABAMA BORDER WHERE
A HIGH TEMPERATURE MIGHT REACH 60. 

ATMOSPHERIC MOISTURE INCREASES FROM THE WEST ON FRIDAY, AS SURFACE
WINDS BECOME SOUTHERLY. THE CHANCE FOR RAIN ALSO GRADUALLY
INCREASES THROUGH SATURDAY NIGHT.  

LONG TERM...OUR NORTHWEST FLOW PATTERN SENDS A COLD FRONT
CHARGING SOUTHWARD INTO OUR AREA ON SUNDAY, AS DAYTIME TEMPERATURES
PUSH INTO THE 60S. SHOWERS AND THUNDERSTORMS WILL BECOME LIKELY
AND CONTINUE INTO SUNDAY NIGHT. BELIEVE IT OR NOT, ANOTHER
STRONGER COLD FRONT DROPS IN ON MONDAY, KEEPING AT LEAST A SLIGHT
CHANCE FOR SHOWERS RUNNING. GFS SHOWS A -5 DEG 850MB ISOTHERM
DROPPING INTO OUR NORTHWEST BY 00Z TUE. ALAS, WINTER SEEMS TO HAVE
ITS TEETH LATCHED INTO OUR HIND END, WITH LITTLE INTENTION OF
REALLY LETTING US GO...AT LEAST NOT YET.

.OHX WATCHES/WARNINGS/ADVISORIES...
NONE.
