AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 527 PM CDT SAT JUL 20 2013 .AVIATION 00Z DISCUSSION... GENERALLY DRY AND WARM PATTERN WILL PARTIALLY TRANSITION AS WEAK NW-SE UPPER LEVEL RIDGING CONTINUES TO SLOWLY BREAK DOWN. TOMORROW...AN UPPER TROUGHING PATTERN WILL BEGIN TO DEVELOP WITH THE AXIS ALIGNED ALONG TH MS RIVER. THE COOLER MID LEVEL TEMPS WILL ALLOW FOR CONVECTION COVERAGE TO BE ON THE INCREASE THROUGH THIS TAF PD. BEST CHANCES FOR SHOWER AND TSTM DEVELOPMENT WILL BE AFT 12Z ON SUNDAY. OTW...SOME LIGHT FOG POSSIBLE TOWARD 12Z. && .PREV DISCUSSION... /ISSUED 254 PM CDT SAT JUL 20 2013/ DISCUSSION...SEVERAL SMALL SHOWERS DEVELOPED AROUND MIDDAY...BUT VERY LITTLE ACTIVITY HAS REMAINED THANKS TO VERTICAL MIXING OF DRY LAYERS AND SUBSIDENCE. TEMPERATURE AND HUMIDITY LEVELS WERE SIMILAR TO YESTERDAY WITH MID AFTERNOON READINGS MOSTLY IN THE LOWER 90S...WITH MID TO UPPER 80S PLATEAU. MOISTURE WILL INCREASE SOME OVERNIGHT...BUT THERE WILL BE LITTLE FORCING FOR ANY MORE THAN 10-20 PERCENT RAIN CHANCE. A SURFACE FRONT CURRENTLY OVER CENTRAL IN/IL AND NORTH MO WILL NOT MOVE MUCH FARTHER SOUTH. MID TN WILL REMAIN UNDER THE SAME AIR MASS WITH LIGHT SOUTH WINDS. FOR THIS FORECAST PERIOD...THE CHANCE FOR RAIN WILL PEAK SUNDAY AFTERNOON THROUGH MONDAY AS A COUPLE OF SHORTWAVE TROUGHS DROP ACROSS THE REGION. MODELS AGREE WITH GOOD MOISTURE POOLING INCLUDING PW VALUES AROUND 2 INCHES. ALSO...MOS POPS ARE IN GOOD AGREEMENT. WE WILL GO WITH "LIKELY" (60 PERCENT) WORDING BOTH SUNDAY PM AND MONDAY...AND AROUND 50 PERCENT SUNDAY NIGHT. ALTHOUGH WE ARE INDICATING "LIKELY"...THIS DOES NOT MEAN A TOTAL WASHOUT...THERE WILL BE RAIN FREE PERIODS. WHEN THUNDERSTORMS ARE OCCURRING...EXPECT SOME VERY HEAVY DOWNPOURS. SOME OF THE STORMS COULD BE STRONG WITH LOCALLY GUSTY WINDS...BUT NO WIDESPREAD OR ORGANIZED SEVERE WEATHER IS EXPECTED. THE CHANCE FOR RAIN WILL TAPER DOWN MONDAY NIGHT INTO TUESDAY...THEN INCREASE AGAIN ON WEDNESDAY AS ANOTHER SHORTWAVE MOVES THROUGH THE AREA. MODELS ARE IN PRETTY GOOD AGREEMENT WITH AN ACTUAL FRONTAL PASSAGE BU THURSDAY BRINGING A PERIOD OF RAIN FREE AND LESS HUMID WEATHER THURSDAY AND FRIDAY. IT LOOKS LIKE ANOTHER SYSTEM WITH POPS RETURNING NEXT WEEKEND...BUT THE DETAILS ARE UNCLEAR AT THIS TIME...SO JUST INCLUDING 20 POPS FOR NOW. 13 && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && 21
