AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 416 PM CDT THU JUL 18 2013 .MESOSCALE UPDATE... SCATTERED CONVECTION ACROSS THE NORTH WORKING WESTWARD ON THE NORTHERN PERIPHERY OF UPPER LEVEL LOW CENTERED DOWN ALONG GULF COAST. STORMS THIS AFTERNOON FOR THE MOST PART HAVE BEEN STRONG TO MARGINALLY SEVERE. EXPECT STORMS TO CONTINUE MOVING WESTWARD OVER THE NEXT COUPLE OF HOURS THEN BEGIN DISSIPATING AS DIURNAL HEATING DIES OFF. BOYD && .PREV DISCUSSION... /ISSUED 258 PM CDT THU JUL 18 2013/ DISCUSSION...SCATTERED THUNDERSTORMS WERE OCCURRING MAINLY ACROSS THE NORTH HALF OF MID TN THIS AFTERNOON...ALONG A MAX CAPE AXIS WITH MIXED LAYER VALUES OVER 3 KJ/KG. THIS AREA WILL CONTINUE TO HAVE THE BEST CHANCE FOR THUNDERSTORMS INTO THE EVENING. STORMS HAVE BEEN PRODUCING VERY HEAVY RAINFALL...NEARLY CONTINUOUS LIGHTNING AND A COUPLE OF ISOLATED WIND/HAIL REPORTS. THIS DIURNALLY DRIVEN ACTIVITY...WITH UNUSUAL EAST TO WEST MOVEMENT...WILL END BY 10 PM OR SO. SOME AREAS THAT RECEIVED THE HEAVIEST DOWNPOURS MAY SEE SOME PATCHY FOG OVERNIGHT. HIGH TODAY WERE NOT QUITE AS HIGH AS EXPECTED IN SOME AREAS THANKS TO THE SCATTERED STORMS AND EXTRA CLOUD COVER. COVERAGE OF STORMS AND CLOUDS IS EXPECTED TO BE A LITTLE LESS TOMORROW...SO WE WILL CONTINUE TO FORECAST HIGHS IN THE LOW TO MID 90S...WITH HEAT INDEX VALUES REACHING 100+ FOR MUCH OF THE AREA. FOR THE WEEKEND...THE HOT RIDGE OVER THE REGION WILL BREAK DOWN. DEVELOPING NORTHWEST FLOW ALOFT WILL CAUSE A FRONT TO DROP ACROSS THE OHIO VALLEY. THIS FRONT WILL NOT MAKE IT THROUGH MID TN...BUT MOISTURE WILL POOL SOUTH OF THE BOUNDARY BRINGING A GOOD CHANCE FOR THUNDERSTORMS...ESPECIALLY SATURDAY NIGHT THROUGH SUNDAY. CONDITIONS WILL REMAIN WARM AND HUMID...BUT THE STORMS AND EXTRA CLOUD COVER WILL LIMIT HIGHS TO THE LOWER 90S MOST AREAS...AND HEAT INDEX VALUES SHOULD STAY BELOW 100 THIS WEEKEND. FOR NEXT WEEK...THE FRONT WILL GRADUALLY DISSOLVE ALLOWING POPS TO DROP BACK INTO THE 20-30 PERCENT RANGE. THE UPPER LEVEL PATTERN WILL FEATURE A RIDGE TO OUR WEST...WITH NORTHWEST FLOW CLIPPING MID TN. IT WILL BE WARM AND HUMID...BUT NOT AS HOT AS THIS WEEK. ANOTHER BOUNDARY IS EXPECTED TO COME DOWN AND ENHANCE THUNDERSTORMS CHANCES BY MIDWEEK. THAT FRONT IS ALSO EXPECTED TO DISSIPATE WITH NO SUBSTANTIAL AIR MASS CHANGE EXPECTED. 13 && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && 01
