.PREV DISCUSSION... /ISSUED 332 PM CDT FRI SEP 4 2015/
Deeper moisture which has been nearer the Gulf Coast in recent
days has now pushed further northward and an associated uptick in
afternoon convection has developed. Meager lapse rates will reduce
the thunderstorm potential and quick dissipation is expected after
sunset. Similar conditions are expected both Sat and Sun with the
deeper moisture in place and convective temps being met each
afternoon. The combination of above normal temps and high
dewpoints will push afternoon heat index values into 100-105
degree range for much of the area.
A slow moving frontal zone will ignite convection across the
central Plains early next week...with any convective outflow
boundary and/or increase in cloud cover being the only reason to
cool temps prior to the actual front. Latest data support the
front pushing into the area Tuesday night with an associated
increase in precip chances. The post frontal airmass looks to
drop temps slightly below normal for late week.
