Area forecast discussion, Jul 4, 6:01 PM CDT, 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
601 PM CDT THU JUL 4 2013

.SHORT TERM...(TONIGHT - SUNDAY)

SCATTERED THUNDERSTORMS HAVE DEVELOPED WEST OF A LINE FROM TABLE
ROCK TO LAKE OF THE OZARKS. RAP MIXED LAYER CAPE VALUES ARE
RANGING FROM 1500-2000 J/KG. THE COMBINATION OF THIS INSTABILITY
AND AN INVERTED V STRUCTURE TO THE LOWER TROP...COULD CREATE A
LIMITED RISK FOR SOME WIND GUSTS THIS AFTERNOON AND EVENING. WITH
-20 LEVELS BEING SO LOW...WE THERE COULD BE A LIMITED HAIL RISK
WITH SOME OF THE STRONGER UPDRAFTS. ANYONE PARTICIPATING IN FOURTH
OF JULY OUTDOOR ACTIVITIES WILL NEED TO WATCH OUT FOR LIGHTNING
STRIKES UNDER THESE UPDRAFTS.

MUCH LIKE LAST NIGHT...A FEW STORMS COULD LINGER WELL INTO THE
EVENING HOURS...AND EVENTUALLY DISSIPATE PRIOR TO MIDNIGHT.

HUMIDITY LEVELS HAVE CREPT UP A LITTLE WITH THE COMMENCEMENT OF
WEAK SOUTHERLY WINDS. THEREFORE OVERNIGHT LOWS WILL BE A LITTLE
WARMER THAN THE PREVIOUS FEW NIGHTS.

A LOWER FREQUENCY OF SHOWERS AND STORMS WILL OCCUR ON FRIDAY
AFTERNOON...AS THE MAIN UPPER LEVEL CIRCULATION SLOWLY MOVES INTO
WESTERN ILLINOIS. HOWEVER...THE BROAD OVERALL TROUGH AXIS WILL
STILL BE ACROSS THE OZARKS. SO CHANCES ARE NOT ZERO FOR
FRIDAY...AND EVEN LOWER CHANCES FOR RAIN WILL OCCUR SATURDAY AND
SUNDAY AFTERNOONS.

LOOK FOR THE WARMING TREND TO PERSIST THROUGH THE WEEKEND...AS
AFTERNOON HIGHS WARM BACK INTO THE UPPER 80S AND LOWER 90S BY
SUNDAY. HUMIDITY WILL ALSO GRADUALLY INCREASE WITH TIME.

.LONG TERM...(MONDAY - THURSDAY)

BOTH THE ECMWF AND THE GFS CONFINE THE SUMMERTIME HIGH CENTER OVER
THE DESERT SOUTHWEST THROUGH MOST OF NEXT WEEK. THE OZARKS WILL BE
POSITIONED ALONG THE NORTHEAST PERIPHERY OF THIS FEATURE...KEEPING
TEMPERATURES FROM GETTING TOO OUT OF HAND...AND KEEPING THE REGION
ALIVE FOR PRECIP CHANCES.

THIS IS A FAIRLY DECENT PATTERN FOR AFTERNOON PULSE
CONVECTION...ESPECIALLY SINCE DEEP MOISTURE WILL GRADUALLY BUILD
INTO SOUTHERN MISSOURI. CHANCES FOR NOCTURNAL STORM COMPLEXES ARE
ALIVE AS WELL UNDER THIS REGIME.

THE BEST SIGNAL FOR A POSSIBLE MCS WOULD BE TUESDAY NIGHT INTO
WEDNESDAY MORNING. BUT TRYING TO FORECAST SOMETHING LIKE THIS 6
DAYS OUT IS PRETTY CHALLENGING.

HAVE A GREAT HOLIDAY WEEKEND AND STAY SAFE.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING)

CONVECTION IN EAST SPRINGFIELD LOOKS TO REMAIN EAST OF THE AREA
FOR NOW. HAVE GONE VCTS AT BOTH SGF/BBG THROUGH 02Z FOR NOW WITH
CLEARING AFTERWARDS. OUTSIDE OF ANY CONVECTION...EXPECTING VFR
