THE OUTFLOW BOUNDARY AT 0235Z EXTENDED FROM JUST SOUTH OF CARTHAGE...TO WATERTOWN...TO MURFREESBORO TO LEWISBURG HEADING NORTHWEST. ESTIMATED TIME OF ARRIVAL AT BNA IS AROUND 0330Z.

WE MAY SEE SHOWER DEVELOPMENT INCREASE FROM JUST SOUTH OF FRANKLIN SOUTHWARD THROUGH MAURY COUNTY AS THE BOUNDARY PASSES. BOYD PREV DISCUSSION... /ISSUED 925 PM CDT THU JUL 14 2011/ UPDATE... NUMEROUS OUTFLOWS AND CONVECTIVE BOUNDARIES CONTINUE TO FLOAT AROUND THE MID-STATE THIS EVENING...IN ADDITION TO WESTWARD MOVING BAND OF SHWRS/STORMS NEAR/ON THE PLATEAU. WHILE MODELS DISSIPATE THIS BAND SOME LATER THIS EVENING/OVERNIGHT...ISO-SCT CERTAINLY POSSIBLE ALL NIGHT AS MOISTURE ADVECTION STRENGTHENS AND WEAK INVERTED LL TROF FORMS ALONG THE PLATEAU TOWARD 12Z. EAST AND SOUTH STILL MOST FAVORABLE...EVEN THRU FRIDAY AS AIRMASS REMAINS WAY UNSTABLE AND SERIES OF IMPULSES RIDE DOWN IN ML/UL NORTHWEST FLOW OVER LL TROF. WILL MAKE A FEW TWEAKS TO WX TONIGHT AND CHANGE ALIGNMENT ON FRIDAY SLIGHTLY. WILL NOT CHANGE TEMPS AT THIS TIME. PREV DISCUSSION... /ISSUED 731 PM CDT THU JUL 14 2011/ UPDATE...FOR 00Z AVIATION FORECAST AVIATION... CONVECTION CONTINUES MAINLY ALONG PLATEAU FROM CROSSVILLE DOWN THROUGH ALTAMONT IN GRUNDY COUNTY. AN ISOLATED SHOWER JUST POPPED UP IN SOUTHWEST DAVIDSON BUT IS DISSIPATING. BELIEVE MUCH OF CONVECTION IS DIURNALLY DRIVEN. EXPECT THE NEARBY THUNDERSTORMS IN THE CROSSVILLE TO DISSIPATE NEXT COUPLE OF HOURS WITH MVFR AFTER MIDNIGHT DUE TO FOG. AS FOR BNA EXPECT VFR CONDITIONS THROUGH MUCH OF THE FORECAST PERIOD. THERE WILL BE SCATTERED THUNDERSTORMS ACROSS MIDDLE TENNESSEE AGAIN ON FRIDAY. BEST TIME FOR STORMS AT BNA WOULD BE AFTER 18Z. CSV WILL BE MORE TRICKY AS I EXPECT SCATTERED SHOWERS IN THE CSV AREA POSSIBLY AROUND 12Z CONTINUING INTO THE AFTERNOON WITH BEST CHANCE FOR THUNDERSTORMS IN THE CSV AREA ALSO AFTER 18Z. BOYD PREV DISCUSSION... /ISSUED 319 PM CDT THU JUL 14 2011/ DISCUSSION...SCATTERED TSRA WERE DEVELOPING OVER MID TN THIS AFTERNOON. CONDITIONS REMAINED WARM AND HUMID WITH TEMPS FROM THE UPPER 80S TO LOWER 90S. A DIFFUSE FRONTAL ZONE REMAINED OVER THE AREA. TEMPS WERE IN THE 80S WITH DEW POINTS IN THE 60S OVER KY...WHILE LOCATIONS SOUTHWEST OF BNA HAD TEMPS IN THE MID 90S WITH DEW POINTS IN THE LOW TO MID 70S. SCATTERED TSRA WILL CONTINUE INTO THE EVENING...ESPECIALLY OVER THE SOUTHWEST COUNTIES (WHERE GREATEST MOISTURE CONVERGENCE EXISTS) AND OVER THE PLATEAU. SOME TSRA WILL OCCUR INTO THE LATE NIGHT HOURS AS WELL...ESPECIALLY SOUTHEAST WHERE AN INVERTED SURFACE TROUGH WILL PROVIDE SOME CONVERGENCE. SO...WE WILL POST POPS THROUGHOUT THE NIGHT. ON FRIDAY...DEEPER MOISTURE WILL SPREAD ACROSS MID TN FROM THE SOUTHEAST WITH THE INVERTED TROUGH. THIS WILL MEAN INCREASING CLOUDS AND POPS. PROBABILITIES WILL RANGE FROM 30 FAR NORTHWEST TO 70 ON THE PLATEAU. THE THICKER CLOUDS AND MORE NUMEROUS TSRA WILL KNOCK TEMPS DOWN ...ESPECIALLY IN THE EAST. THE CHANCE FOR MAINLY AFTERNOON AND EVENING THUNDERSTORMS WILL CONTINUE THROUGH THE WEEKEND AS MOISTURE CIRCULATES AROUND THE EAST COAST SURFACE HIGH. AT THE SAME TIME...HEIGHTS WILL BE RISING...SO THE COVERAGE OF TSRA SHOULD DIMINISH EACH DAY. BY MONDAY...THE COVERAGE OF TSRA WILL BE DOWN TO 20 PERCENT OR LESS. TEMPS WILL BE TOLERABLE FOR THIS TIME OF YEAR...WITH WEEKEND HIGHS MAINLY UPPER 80S TO LOWER 90S. THROUGH THE EXTENDED FORECAST PERIOD...THE STRONG HIGH PRESSURE OVER THE CENTRAL STATES WILL SPREAD EASTWARD...AND EVENTUALLY BE CENTERED OVER TN.
