AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
1106 PM CST Tue Feb 17 2015

.SHORT TERM...(This Evening through Thursday Night)
Issued at 237 PM CST TUE FEB 17 2015

Short-term concerns focus on 1) ongoing band of moderate snowfall
beginning to move through eastern Kansas into western Missouri, 2)
additional snowfall over northeast Missouri tonight and 3) potential
for wind chills 15 below zero late tonight into tomorrow morning
over far northern Missouri.

As of this afternoon, water vapor imagery showed one upper wave near
the KS/NE border responsible for producing the ongoing narrow band
of snowfall. While this band will be relatively fast moving, with
high snowfall ratios and some convective nature to the activity, a
quick burst of one-half to one inch of snow will be possible in the
heaviest activity in a short period of time. The highest snowfall
totals are expected to reside over EC KS into WC MO, where up to two
inches of snow are possible, primarily between 4-7pm. Likewise, a
winter weather advisory has been issued for this area. The outskirts
of this activity, including portions of the KC Metro, may receive up
to one-half inch of snow. While the snowfall amounts will be lower,
caution during the late afternoon commute is strongly encouraged as
visibility may be temporarily reduced and some roadways may become
slick. All of this activity will move south of the forecast area a
couple hours post-sunset.

An additional area of snowfall may develop over far northeast
Missouri later this evening into tonight as another wave currently
over the eastern Dakotas approaches the region. Portions of far
northeast Missouri may receive up to one-half inch of snowfall with
this activity. This is a lower confidence forecast and the overall
impact is expected to be less due to the snowfall amounts and time
of day.

Increasing northerly winds will enter the forecast area later
tonight, with the strongest winds generally collocated with some of
the coldest overnight temperatures. The result will be wind chill
readings falling to 15 below zero across far northern Missouri, with
sub-zero wind chill readings elsewhere by early tomorrow morning.
Have issued a wind chill advisory for the coldest wind chill
readings of far northern Missouri.

Otherwise, Wednesday looks to be much more tranquil weather-wise as
surface high pressure settles into the region. That said,
temperatures will be well below normal, with high temperatures in
the teens. Overnight lows into Thursday morning will be bitterly
cold with light winds and mostly clear skies, with readings in the
single digits. Some locations may fall below zero, especially in
snow-covered, favored low-lying cold-air drainage areas. The cold
weather will persist into Thursday with well-below normal
temperatures. Increasing isentropic ascent may yield areas of
snowfall beginning Thursday evening into Thursday night across the
area. Some light snowfall accumulation is expected, but the details
remain uncertain at this time.

.LONG TERM...(Friday through Tuesday)
Issued at 237 PM CST TUE FEB 17 2015

The cold and active weather pattern will persist through the
extended portion of the forecast. We'll start the day Friday with a
general northwesterly flow regime and the possibility of light
wintry mix shifting eastward through the forecast area. As a surface
high moves over the southeastern US, a deepening trough is expected
through Rockies with a developing surface low in the high Plains.
This may briefly bring about southerly flow later in the day Friday
which may then advect some warmer air aloft. This then poses
significant challenges in determining precipitation type as the the
low moves across the center of the county. Surface temperatures may
be slow to respond to any potential warm up for Friday so if
precipitation can move northward after the initial Thursday
night/early Friday round, there is a chance that it may be in the
form of freezing rain. As the storm system then progresses eastward
overnight, precipitation should become more widespread. Surface
winds should back to the northeast, entrenching low level cold air.
But aloft, models indicate the 0C line for 925mb and 850mb splitting
the area. This is good signal of mixed precipitation with freezing
rain, sleet and snow possible from Friday night through much of the
day Saturday until colder air deepens enough by Saturday evening to
allow a changeover to all snow. By Sunday into, an impressive
1040+mb surface high should track down the Plains keeping
temperatures well below normal for late February.

.AVIATION...(For the 06Z TAFS through 06Z Wednesday Night)
Issued at 1106 PM CST TUE FEB 17 2015

VFR conditions are expected to persist through the forecast period.
West northwest winds between 5 to 10 kts will veer to the northwest
and increase during the mid-morning hours, reaching sustained speeds
of 12-15 kts with gusts to 25 kts during the daylight hours.
Scattered cu may develop during the afternoon, but should remain
above 3 kft.
