.NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
WARM ADVECTION LOOKS TO TAKE HOLD FOR THE REST OF THE DAY WITH
ABUNDANT SUNSHINE EVEN WITH DIURNAL CUMULUS BUILDUPS.
HOWEVER...POOR MIXING BELOW 850 MB SHOULD KEEP A LID ON RUN AWAY
WARMING. EVEN WITH SAID POOR MIXING...HIGHS SHOULD MAKE RUNS AT
90F IN MANY LOCATIONS SIMPLY DUE TO THE WARM START AND ABUNDANT
JULY SUN. ADDITIONALLY...A FAIRLY STRONG CAP AROUND 10 KFT SHOULD
KEEP ANY SHOWERS/THUNDERSTORMS FROM FORMING EVEN WITH THE
WARM/HUMID/RATHER UNSTABLE AIR MASS IN PLACE. FRIES
