000 FXUS64 KMRX 240646 AFDMRX AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 246 AM EDT SUN MAY 24 2015 .SHORT TERM (TODAY AND TONIGHT)... A RIDGE THROUGH THE MID AND UPPER LEVELS WILL CONTINUE TO PROVIDE DRY AND MOSTLY SUNNY CONDITIONS ACROSS THE AREA TODAY. LOW LEVEL THICKNESS VALUES WILL BE A LITTLE HIGHER THAN YESTERDAY...SO HIGH TEMPS WILL BE A DEGREE OR TWO HIGHER. THE NAM DEVELOPS CONVECTION THIS AFTERNOON AND EVENING OVER AL...MOVING IT NORTHWARD AND INTO OUR SOUTHERN SECTIONS LATE TONIGHT. WILL HAVE A SLIGHT CHANCE OF SHOWERS SOUTH TO ACCOUNT FOR THIS POSSIBILITY. .LONG TERM (TOMORROW THROUGH SUNDAY)... PRETTY MUCH THE ENTIRE AREA WILL MAINTAIN PRECIPITATION CHANCES THROUGHOUT THE LONG TERM PORTION OF THE FORECAST. RAIN CHANCES WILL CREEP IN FROM THE WEST ON MONDAY AS AS THE TROUGH MOVES NORTHEAST ACROSS THE PLAINS STATES AND HELPS SHOVE THE HIGH PRESSURE FURTHER EAST OFF THE ATLANTIC COAST OF THE UNITED STATES. CONVECTION WILL THEN BE POSSIBLE THROUGH THE REMAINDER OF THE WEEK INTO THE WEEKEND. DO NOT THINK THERE WILL BE RAIN ON THE RADAR THE ENTIRE WEEK, BUT PINING DOWN WHEN THE BREAKS WILL BE IS A BIT DIFFICULT AT THIS TIME. THING TO TAKE AWAY IS THAT IT WILL LIKELY RAINY AND OVERCAST WEEK FOR THE FORECAST AREA. A FEW SHORTWAVES WILL MOVE ACROSS THE PERIPHERY OF THE RIDGE BRINGING SOME OF THE BEST CHANCES FOR MORE WIDESPREAD RAIN TO THE AREA. RIGHT NOW LOOKS LIKE TUESDAY NIGHT INTO WEDNESDAY WILL BRING THE BEST CHANCE FOR THOSE WIDESPREAD SHOWERS AND THUNDERSTORMS. SOME WEAK RIDGING WILL MOVE OVER THE AREA AT THE END OF THE WORK WEEK INTO THE WEEKEND, BUT DUE TO RESIDUAL MOISTURE HANGING AROUND, THERE WILL BE CONTINUED CHANCES FOR CONVECTION. RAIN CHANCES CONTINUE INTO THE WEEKEND AND BEYOND THE END OF THE 7-DAY FORECAST. && .PRELIMINARY POINT TEMPS/POPS...
