..DISCUSSION...
SEASONAL PATTERN CHANGE WILL BE IN FULL SWING THIS WEEKEND THROUGH
MID-NEXT WEEK AS A PROGRESSIVE BUT ENERGETIC TROUGH SHIFTS ACROSS
THE NRN/CNTRL PORTIONS OF THE COUNTRY. THIS WILL SEND A STRONG COLD
FRONT SWD ACROSS ALL BUT FL AND DEEP S TX BY NEXT FRI. AHEAD OF
THIS POTENT FRONT...IT APPEARS THAT A SUCCESSION OF WEAKER FRONTS
WILL RELEGATE THE PRIMARY AND QUALITY MOISTURE SOURCE WELL TO THE S.
AS A RESULT...INSTABILITY WILL LIKELY BE LIMITED AHEAD OF THE
STRONGER FRONT. AT THE SAME TIME...PRIMARY WIND MAX ALOFT WILL PASS
N OF THIS REGION AS THE UPR TROUGH MAINTAINS A POSITIVE TILT. AS A
RESULT...WIDESPREAD SVR WEATHER EPISODES ARE NOT LIKELY.
