AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
826 PM CDT FRI JUN 26 2015

.UPDATE...MOST DIURNAL STORM ACTIVITY IS GONE SO HAVE UPDATED TO HAVE
ONLY A SLIGHT CHANCE OF RAIN THIS EVENING. LATER TONIGHT ESPECIALLY
NORTH OF INTERSTATE 20...ADDITIONAL SCATTERED STORMS WILL MOVE INTO
THE FORECAST AREA FROM THE NORTH. CURRENTLY THE ACTIVITY OVER CENTRAL
ARKANSAS APPEARS TO BE WEAKENING AND THE STORMS ARE WELL BEHIND AN
OUTFLOW BOUNDARY. WILL CONTINUE WITH THE LIMITED RISK OF SEVERE
STORMS IN THE GREENVILLE REGION IN THE HAZARDOUS WEATHER
OUTLOOK...BUT IF WEAKENING TRENDS CONTINUE...WE MAY BE ABLE TO DROP
THAT LATER THIS EVENING.

NO ADDITIONAL CHANGES TO THE FORECAST ARE PLANNED. /SW/

&&

AVIATION...AFTERNOON STORM ACTIVITY HAS DISSIPATED THIS EVENING
AROUND THE TAF SITES. ADDITIONAL STORMS ASSOCIATED WITH THE FRONT
WILL MOVE SOUTHEAST INTO THE AREA TONIGHT AND SATURDAY CAUSING LOCAL
CATEGORY RESTRICTIONS. THERE MAY ALSO BE SOME MVFR CIGS BETWEEN 09Z
AND 15Z. /SW/

&&

.PREV DISCUSSION... /ISSUED 405 PM CDT FRI JUN 26 2015/

DISCUSSION...THERES A BIT MORE CONVECTION ONGOING THIS AFTERNOON
THAN WE SAW YESTERDAY AFTERNOON ACROSS THE AREA. AS WAS EXPECTED PER
THE MORNING LOCAL MICROBURST ANALYSIS...THIS ACTIVITY REMAINS
SUBSEVERE BUT CAN BRING SOME VERY HEAVY DOWNPOURS AND FREQUENT
LIGHTNING. THIS ACTIVITY IS MOVING FROM WEST TO EAST. ALL OF THIS
COMES AS AN UPPER TROUGH IS NOW LOCATED ACROSS THE REGION AND
TEMPERATURES HAVE BEEN ABLE TO WARM INTO THE LOWER 90S. FURTHER
NORTH...A COLD FRONT SITS ACROSS THE MID-MISSISSIPPI VALLEY REGION
AND THIS IS POISED TO DROP SOUTH INTO OUR REGION LATER TONIGHT
THROUGH TOMORROW. THIS WILL BRING SOME MORE SHOWERS AND STORMS TO THE
REGION. THE NORTHERN PORTION...MAINLY THE DELTA...COULD SEE A FEW
STRONG TO SEVERE STORMS AS IT ENTERS THE ARKLAMISS LATER THIS EVENING
INTO THE LATTER PORTIONS OF TONIGHT AS THE FRONT DROPS SOUTH AND
THERE REMAINS ENOUGH INSTABILITY AND LAPSE RATES IN THE AREA. HI-RES
MODEL GUIDANCE SHOWS A FEW ROBUST CELLS DROPPING INTO OUR REGION
BEFORE WEAKENING. WILL KEEP A LIMITED RISK FOR SOME LOCATIONS IN THE
DELTA THROUGH THE EVENING AS THE FRONT MOVES IN.

THE FRONT WILL CONTINUE TO TREK SOUTH THROUGH TONIGHT INTO SATURDAY.
IT IS NOT OUT OF THE REALM OF POSSIBILITY FOR A STORM TO GET STRONG
OR MAYBE SEVERE ACROSS THE SOUTHERN PORTIONS OF MY CWA AS THE FORCING
INTERACTS WITH SOME DAYTIME HEATING. HOWEVER...SHEAR AND LAPSE RATES
ARE RATHER POOR DOWN THERE FOR TOMORROW SO WILL NOT OUTLOOK ANYTHING
AT THIS TIME. THE OTHER STORY WITH THIS FRONTAL PASSAGE IS THE COOLER
AND DRIER AIR THAT WILL MOVE INTO THE REGION FOR SUNDAY. TEMPERATURES
SHOULD DROP INTO THE 80S WITH DRIER DEWPOINTS INTO THE 60S AND EVEN
SOME 50S GIVEN SUFFICIENT MIXING. SHOULD FEEL RATHER NICE FOR ANY
OUTDOOR PLACES GIVEN THAT IT IS LATE JUNE. THE FRONT WILL CLEAR THE
REGION BY SUNDAY AND CONDITIONS WILL CLEAR MAKING FOR A RATHER NICE
DAY. PLEASANT CONDITIONS WILL CONTINUE INTO MONDAY THOUGH SOME
CONVECTION SHOULD RETURN TO THE HIGHWAY 98/84 CORRIDOR DURING THE
AFTERNOON. EVEN OVERNIGHT LOWS WILL BE NICE AND SOME LOCATIONS WILL
DROP INTO THE 60S. /28/

LOW LEVEL FLOW WILL TURN BACK AROUND MONDAY AS A NEW JET STREAK/MID
LEVEL WAVE SWINGS INTO THE MIDWEST ON TUESDAY. THE BEST MID/UPPER
DYNAMICS ASSOCIATED WITH THIS FEATURE WILL STAY NORTH OF THE REGION,
BUT THE AIRMASS WILL MOISTEN AND CONVECTION (ESPECIALLY DIURNAL) WILL
BECOME MORE PERVASIVE TUESDAY INTO WEDNESDAY. THOUGH THE UPPER TROUGH
IS EXPECTED TO GRADUALLY LOSE MAGNITUDE THROUGH THE END OF THE WEEK,
MID LEVEL SHORTWAVES WILL CONTINUE TO PASS NEAR THE AREA, KEEPING
CONTINUED RAIN CHANCES ESPECIALLY FARTHER NORTH. /DL/
