.SHORT TERM...(Tonight through Friday night)
Issued at 232 PM CDT Wed Oct 26 2016

Prefrontal warming is greater than blended models, and slight
adjustments were made to the immediate term grids to reflect that.

The cold front stretches from the IA/IL border across northwest
MO, and is making its approach on the PAH FA. It has been
consistently modeled to increase clouds and spread Pops across the
PAH FA as it makes its passage tonight. While model differences
exist, all suggest at least marginally supportive mention of
thunder is warranted, even though it does appear that the two main
convective areas of pcpn will break largely just to our north, and
just to our south. This may taper pops off a tad and drive them
largely in the chance category range through the overnight hours,
but we have collaboratively blended to fit the pic.

Tmrw, cooler temps funnel in as the post frontal airmass migrates
across the mid Mississippi river valley. Then after this briefly
cooler day where we drop back to the 60s and low 70s for highs and
the 40s for lows, we`ll bounce right back to 70s/50s to finish out
the week, beginning a warm trend that looks to stay awhile.

.LONG TERM...(Saturday through Wednesday)
Issued at 232 PM CDT Wed Oct 26 2016

Confidence continues to rise with the extended with the dry trend
and warmer temperatures looking more solid.

The front that was progged to move through the area early in the
weekend now appears to stay just north of the region. This is most
likely due to the upper level ridging centered over Texas that
slowly moves into the central Gulf states. The next chance of
rain will be next week at the earliest. However available moisture
will be scant at best as the high pressure at the surface and
aloft will keep the Gulf closed for the most part. Although late
in the period there could be some moisture return late in the
forecast as the high slowly drifts east. By Tuesday of next week a
cold front is still forecast to move into the area but once again
the available moisture is limited. But with high pressure to the
north of this front it should have better odds to make it through
the region. We may have to include some low end pops day 6/Tuesday
but confidence in rainfall would be minimal at best. The I-64
corridor would be the best chance for any measurable rain. As for
temperatures...the drier air is much easier to heat up than moist
air. Therefore will increase temps a little in the extended to
accommodate the dry air.


Issued at 232 PM CDT Wed Oct 26 2016

Expect lowering CIGS thru the VFR to potentially MVFR as the front
moves in and ultimately across the flight terminals by the end of
the package. Associated shower chances/restricted vsbys will be
mainly during the overnight ptn of the forecast, and will range
from vicinity to temporary mention. South winds, which may gust at
times this pm, will shift to the west or northwest after fropa,
during the planning period.
