..00z aviation update...

Short term...(this evening through friday)
issued at 230 PM CST Thu Feb 23 2017

The unseasonably warm weather will continue into the evening ahead
of surface low pressure that will track across southern Kansas
toward west central Missouri. The warm sector is progged to remain
capped in advance of the trailing cold front. Therefore
development of any convection is not expected at this time.

The cold front will push across the Missouri/Kansas border after
midnight and all of the area by midday Friday. There is an outside
chance that isolated showers could develop across the Eastern
Ozarks Friday morning but dry frontal passage is generally
expected.

Cold air advection following the frontal passage will cause
temperatures to steady off if not fall during the day Friday. The
falling dewpoints and gusty winds up to 30 mph will result in at
least a limited fire weather risk.

Long term...(friday night through thursday)
issued at 230 PM CST Thu Feb 23 2017

A cooler and more seasonable airmass will settle over the area
Friday night and Saturday as surface high pressure builds into the
region.

Southerly flow returns Sunday as high pressure shifts off to the
east while a more zonal upper air patter unfolds. A minor
shortwave riding through this flow will bring a chance of light
rain Sunday into early Monday. A few flakes of snow may mix with
the rain as precipitation begins early Sunday and as it ends early
Monday. No accumulation is expected.

Any active weather will remain in place going into next week. A
pronounced upper level trough will take shape out west early next
week and transition eastward with time. Medium range models
continue to differ on the details on the evolution of this system
and the corresponding chance of rain. As it stands now it appears
a good chance of rain and perhaps a few thunderstorms will develop
Tuesday and possibly into Wednesday. The forecast confidence
during this time period is low. Temperatures will be closer
seasonal averages heading into next week.

Aviation...(for the 00z tafs through 00z Friday evening)
issued at 556 PM CST Thu Feb 23 2017

VFR conditions expected through the evening and into the
overnight. Cloud cover may allow a drop into MVFR range Friday
morning before improving again by midday.

Generally speaking, mostly a wind forecast through the period. A
cold front will shift our southerly flow to a more westerly and
eventually northwesterly flow tomorrow. Winds are expected to be
gusty at times. In addition to the wind shift, low level wind shear will be
possible tonight for much of the area.
