.SHORT TERM...  (Through Late This Afternoon)
Issued at 252 AM CDT Wed Sep 21 2016

Not much change in airmass from yesterday and therefore went with a
persistence forecast for today. Expect max temps to be very similar
to yesterday given the setup today. The sfc ridge axis is expected
to remain roughly in place and will help suppress temps slightly
across ern portions of the CWA.

No precip is anticipated today with a strong cap in place centered
around 800 mb.

.LONG TERM...  (Tonight through Tuesday)
Issued at 252 AM CDT Wed Sep 21 2016

Summer like conditions to persist through the rest of the work week
and into the weekend as surface ridge remains in place. Will see
highs in the 85 to 90 degree range through Saturday.

Otherwise, digging upper level trof and associated surface cold
front over central plains to begin lifting out towards the
forecast area Saturday night with best chances of storms Sunday
through Monday. Some of the extended models stall out the system
over the region, so kept slight chance pops for Monday night and
Tuesday. With the cloud cover and precipitation, temperatures will
be near normal in the mid to upper 70s for the first part of the
work week.

Issued at 623 AM CDT Wed Sep 21 2016

VFR and dry thru the period. Sly winds return today with some CU
developing. Winds become light and back slightly tonight. Do not
anticipate fog development tonight due to mixing today and warmer
temps expected tonight.
