.DISCUSSION...
Issued at 255 PM CST SUN FEB 1 2015

Light snow continues this afternoon generally near and north of the
Missouri River...and will gradually taper off from west to east
through the evening. Any additional accumulation should be confined
to areas near and north of the US 36 corridor and east of I-35 where
up to another inch of snow may fall. The bigger issue will be gusty
winds to 40 mph which is causing substantial blowing snow over far
northeast Kansas and northwest Missouri which will spread into much
of north central and northeast Missouri over the next few hours.
Visibilities could drop as low as a half mile across these locations,
and could even see near-blizzard conditions particularly in wide open
areas across northern Missouri and extreme northeast Kansas. Will
therefore keep the current advisories and warnings in place for at
least a few more hours.

Winds will quickly die down later this evening with high pressure
building in from the northwest. This will allow temperatures to
plummet into the single digits with sub-zero readings likely over far
northwest Missouri where winds will be lighter and skies will clear
quicker. Wind chill values could approach -15 across far northwest MO
overnight.

Light southerly flow will return to the area on Monday but
temperatures will struggle to rise out of the teens across the
deepest snow pack in northern MO and 20s elsewhere. Southerly flow
will increase Monday night into Tuesday so that temperatures
overnight will only fall a few degrees...rising into the 40s on
Tuesday across the southern half of the area. Lowered Tuesday`s highs
quite a bit across the northern half where a dense snow pack will be
in place. Highs across this region may not make it out of the
lower/mid 30s.

Another strong front will slide through the region on Wednesday with
temperatures falling into the 20s through the day. Confidence is
increasing on a band of snow sweeping through the region behind the
front Wednesday afternoon in response to rather deep post-frontal
frontogenesis. This activity could drop an inch or two of snow across
some locations especially given the cold airmass behind the front.
Unfortunately models are not agreeing on the location of this band,
although the general trend has been to shift north into northern
Missouri and Iowa. This could easily shift back south, so kept a
broad chance PoPs across the entire CWA for now.

Another frigid night is in store Wednesday night with sub-zero
readings expected north of the Missouri River. Wind chill values
could dip below -15 especially across far northern MO and KS. Will
finally see warmer temperatures returning for the end of the week
with a large upper ridge building in from the west.

.AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon)
Issued at 1129 AM CST SUN FEB 1 2015

Several more hours of light snow expected to continue across areas
north of an IXD to COU line this afternoon, possibly into early this
evening. Conditions are likely to remain IFR through this time,
although any additional accumulation on runways should only be an
inch or less, mainly north of the Missouri River. Winds will increase
significantly this afternoon with occasional gusts in excess of 30 kt.
