Severe Thunderstorm Warning 305, NWS Jackson, MS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
351 PM CDT THU JUN 13 2013

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...THE PRIMARY CONCERN
FOR THIS PERIOD WILL BE THE SEVERE WEATHER RISK CONTINUING INTO THIS
EVENING AS AN OUTFLOW BOUNDARY ALONG WITH A WEAK FRONT MOVES THROUGH
THE REGION. THIS SYSTEM WILL RUN INTO AN UNSTABLE AIRMASS IN PLACE
ACROSS THE REGION LATE THIS AFTERNOON AND INTO THE EVENING HOURS.
THE STORMS SHOULD BECOME SEVERE RAPIDLY AS THEY PUSH THROUGH THE
CWA. THE PRIMARY RISK WITH THESE STORMS WILL BE 60-70 MPH WIND
GUSTS...HAIL...AND FREQUENT LIGHTNING. MOST OF THE THUNDERSTORM
ACTIVITY SHOULD BE OUT OF THE CWA AROUND OR SHORTLY AFTER MIDNIGHT
TONIGHT.

FOR FRIDAY INTO FRIDAY NIGHT EXPECT LESS WARM AND HUMID CONDITIONS
IN THE WAKE OF THE WEAK FRONT. IN THE WAKE OF THE EXPECTED ROUND OF
STORMS...DRIER AND SLIGHTLY COOLER AIR WILL FILTER INTO THE AREA.
TEMPS WILL RANGE FROM THE UPPER 80S NORTH TO LOWER 90S ACROSS THE
SOUTH. SFC DEWPTS WILL FALL INTO THE 60S WHICH WILL KEEP HUMIDITY
VALUES LOWER. THIS WILL ALSO RESULT IN A COOL NIGHT FRI WITH LOWS IN
THE LOWER TO MID 60S.

WARM AND DRY CONDITIONS WILL CONTINUE INTO SATURDAY AS THE REGION
WILL BE UNDER THE INFLUENCE OF HIGH PRESSURE. EXPECT WARMER TEMPS
SATURDAY WITH HIGHS RANGING FROM THE LOWER 90S NORTH TO THE MIDDLE
90S SOUTH. /27/

.LONG TERM...SUNDAY THROUGH THURSDAY...THE WEATHER PATTERN WILL
BEGIN TO CHANGE BY LATER SUNDAY AND CONTINUING THROUGH THE REMAINDER
OF THE WEEK. THE UPPER RIDGE WILL BREAK DOWN AS A PROGRESSIVE
SHORTWAVE TROUGH MOVES ACROSS THE GREAT LAKES REGION. THIS WILL
BRING A WEAK COOL FRONT TOWARD OUR REGION FOR TUESDAY. MODELS SHOW
THIS FRONT STALLING ACROSS THE NORTHERN SECTIONS OF THE CWA. SEVERAL
DISTURBANCES WILL MOVE ALONG THIS FRONT THROUGH THE END OF THE
PERIOD...LEADING TO A CHANCE FOR SHOWERS AND THUNDERSTORMS EACH
DAY.  WITH THE BREAKDOWN OF THE UPPER RIDGE...AND THE INCREASED
CHANCES FOR RAIN...TEMPERATURES SHOULD BE SLIGHTLY COOLER/CLOSER TO
BUT STILL A LITTLE ABOVE SEASONAL NORMALS/ IN THE 90-93 DEGREE
RANGE. /28/

&&

.AVIATION...CONVECTION IS EXPECTED TO DEVELOP NORTH OF THE AREA AND
SPREAD SOUTH THROUGH THE LATE AFTERNOON AND EVENING HOURS AS A COLD
FRONT DROPS SOUTH THROUGH THE REGION. THESE STORMS COULD BE SEVERE
AND CAPABLE OF PRODUCING DAMAGING WINDS AND HAIL. MVFR TO LIFR
CEILINGS AND/OR VISIBILITIES WILL BE LIKELY AT SITES THAT OBSERVE
CONVECTION DURING THIS TIME. WINDS BEHIND THE FRONT WILL BECOME
NORTHERLY LATE TONIGHT INTO FRIDAY. /19/
