.DISCUSSION...
/ISSUED 1051 AM CDT FRI SEP 4 2015/
DENSE FOG WAS PRESENT THIS MORNING IN LOCATIONS THAT RECEIVED
RAINFALL YESTERDAY AND THE USUAL SPOTS NEAR BODIES OF WATER AND IN
THE VALLEYS. CURRENT OBS SHOW THE FOG HAS LIFTED AND TEMPS ARE
RUNNING WARMER THAN THIS TIME YESTERDAY AS MOST LOCATIONS ARE ALREADY
IN THE 80S AS OF 15Z.

AN UPPER LEVEL LOW IS BEGINNING TO MOVE INTO THE UPPER WEST COAST AS
THE THE CENTRAL PORTION OF THE US HAS A BROAD RIDGE OF HIGH PRESSURE
IN PLACE. SFC HIGH PRESSURE CENTERED OVER THE OH RIVER
VALLEY...EXTENDS SOUTH INTO THE TN VALLEY. THIS WILL HELP KEEP
CONVECTION THAT DEVELOPS TO ISOLATED COVERAGE. NE AL HAS THE HIGHEST
POPS FOR TODAY AS THEY ARE ON THE PERIPHERY OF THE UPPER LEVEL RIDGE
WHERE A COMBINATION OF A DISTURBANCE AND DAYTIME HEATING WILL BE THE
SOURCE OF CONVECTION. CAPE VALUES OF ~2000 ARE HIGHEST OVER IN THE NE
AND NO SHEAR CONCERNS WITH SUCH LIGHT WINDS...THEREFORE SUMMERTIME
THUNDERSTORMS ARE POSSIBLE WITH GUSTY WINDS AND HEAVY DOWNPOURS.
