.PREV DISCUSSION... /ISSUED 256 PM CDT FRI JUL 4 2014/

DISCUSSION...
SCATTERED SHOWERS AND THUNDERSTORMS ARE BEGINNING TO POP
UP ACROSS PORTIONS OF SOUTHEAST TEXAS...ESPECIALLY OUT WEST
AND SOUTHWEST WHERE TEMPERATURES ARE THE WARMEST. A COUPLE
MORE HOURS OF HEATING SHOULD ALLOW CONVECTIVE TEMPERATURES
TO BE REACHED RESULTING IN MORE SHOWER AND THUNDERSTORM
DEVELOPMENT. SOME OF THE STRONGER ACTIVITY WILL HAVE THE
POTENTIAL TO PRODUCE GUSTY WINDS...SMALL HAIL...FREQUENT
LIGHTNING AND BRIEF HEAVY RAINFALL. THINGS SHOULD QUIET
DOWN THIS EVENING WITH THE LOSS OF DAYTIME HEATING. THE
MAJORITY OF THE LATEST MODEL RUNS ARE POINTING TOWARD
SOMEWHAT LESS STORM COVERAGE OVER THE WEEKEND AND ON INTO
THE FIRST HALF OF THE NEXT WEEK...SO WILL CONTINUE TO STICK
WITH 20%-30% POPS FOR MAINLY DAYTIME ACTIVITY. SHOULD SEE
LITTLE CHANGES IN TEMPERATURES THROUGH THE PERIOD WITH NEAR
NORMAL READINGS.  42

MARINE...

UNUSUALLY STRONG HIGH PRESSURE FOR THIS TIME OF YEAR FROM
BROWNSVILLE TO SHREVEPORT TO CHICAGO. RIDGE AXIS HELPING WITH THE
FORMATION OF THE LANDBREEZE/SEABREEZE CIRCULATION EACH MORNING
THROUGH THE WEEKEND. LIGHT ONSHORE THE PREVAILING FLOW BUT WILL BE
INCREASING LATE MONDAY AND TUESDAY AS UPPER TROUGH DROPS INTO THE
GREAT LAKES REGION INCREASING THE SOUTHERLY FLOW AT LEAST BRIEFLY.
