AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 1253 PM CDT SAT JUN 26 2010 .UPDATE...26/18Z AVIATION FORECAST && .AVIATION... LOOK FOR SCATTERED TSTMS THIS AFTERNOON ACROSS THE MID STATE AS DIURNAL HEATING CRANKS UP. STORMS WILL BE MOVING EAST AT ABOUT 10 15 MPH AND PRODUCE WET MICROBURSTS CONDITIONS WITH BRIEF HEAVY RAINFALL AND REDUCED VSBYS FOR A SHORT PERIOD OF TIME. OUTSIDE OF STORMS GENERALLY VFR CONDITIONS BUT MVFR LATE TONIGHT DUE TO FOG. BOYD && .PREV DISCUSSION... /ISSUED 925 AM CDT SAT JUN 26 2010/ UPDATE...GRIDS AND ZONES HAVE ALREADY BEEN UPDATED TO MENTION THUNDER POPS THROUGHOUT THE DAY. SCATTERED CONVECTION ALREADY FIRED UP OVER OUR NORTHWEST COUNTIES...AND A CELL HAS DEVELOPED OVER NASHVILLE. DIFFUSE FRONTAL ZONE AND LEFTOVER BOUNDARIES WILL CONTRIBUTE TO CONTINUED CONVECTIVE DEVELOPMENT AS THE ATMOSPHERE DESTABILIZES TODAY. POPS WILL RANGE FROM AROUND 10 NORTHEAST TO 40 SOUTHWEST. ALSO ADJUSTED TEMPS UP A DEGREE OR SO...MORNING SOUNDING AND UPSTREAM COMPARISONS INDICATE MANY AREAS WILL TOUCH 95 TODAY...BUT THAT WILL DEPEND ON EXACTLY WHERE THUNDERSTORMS OCCUR. WE ARE NOT UNDER AN SPC SLIGHT RISK FOR SEVERE WX. HOWEVER...GOOD INSTABILITY WITH WEAK SHEAR WILL PROMOTE ISOLATED DOWBURST WIND EVENTS. A FEW SEVERE WARNINGS WILL PROBABLY BE ISSUED. PREV DISCUSSION... /ISSUED 545 AM CDT SAT JUN 26 2010/ AVIATION...BNA/CSV...AFTER TWO DAYS OF SCATTERED CONVECTION, WE'RE LOOKING AT A DRIER AIR MASS TODAY. AT MOST, WE'LL SEE ISOLATED AFTERNOON STORMS ACROSS MIDDLE TENNESSEE, SO WILL HANDLE THIS WITH CB REMARKS IN THE TAF'S. OTHERWISE, LOOK FOR VFR WX W/ GENERALLY LIGHT SW WINDS. PERHAPS SOME LIGHT FOG LATE TONIGHT AT CSV. PREV DISCUSSION... /ISSUED 306 AM CDT SAT JUN 26 2010/ ISOLATED TO SCATTERED CONVECTION TODAY UNDER LIGHT SLY FLOW AT THE SFC WITH A FRONTAL SYSTEM WELL TO THE NORTH OVER THE GREAT LAKES AND NRN PLAINS. DIRUNALLY MODULATED CONVECTION WILL CONTINUE THROUGH THE WEEKEND AS THE FRONT WORKS IT WAY SWD INTO THE OH/TN VALLEYS. FRONT PUSHES SWD THROUGH THE AREA LATE MON. BUT NOT A LOT OF COOL AIR BEHIND IT...MAINLY DRIER AIR. THE INITIAL H5 SHORTWAVE MERELY PUSHES THE FRONT FURTHER SWD. HOWEVER...HIGHS WILL STILL BE IN THE 90S IN THE MON-WED PERIOD. HAVE TO WAIT A DAY OR TWO UNTIL WED NGT WHEN THE UPPER TROUGH DEEPENS SGFNTLY OVER ERN CANADA AND TURNS UPPER FLOW MORE NLY. THIS WILL BRING COOLER AIR AND DROP DAYTIME HIGHS INTO THE MID 80S. MAIN EFFECT OF THIS SCENARIO IS 3 FOLD: A) REDUCE THE DAYS OF ABOVE NORMAL TEMPS B) REDUCE THE HUMIDITY AND C) SGFNTLY DIMINISH THE PROBABILITY OF RAINFALL. CPC PROGS CONTINUE TO INDICATE ABOVE NORMAL TEMPS IN THE 6-10 AND 8-14 DAY PERIODS. BUT THEN...WE'VE BEEN ABOVE 90 DEGREES FOR 14 OUT OF THE LAST 15 DAYS. SO I GUESS BEING 1-2 DEGREES ABOVE NORMAL IS BETTER THAN BEING 7-8 DEGREES ABOVE NORMAL. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && 01
