...Another Round of Snow Today...

.SHORT TERM...(Today and tonight)
Issued at 235 AM CST Mon Jan 15 2018

An upper level low is currently spreading south across Minnesota
early this morning. Ahead of this feature an area of precipitation
has developed across central Kansas to the east into Illinois.
Temperatures across southeastern Kansas into far southwest
Missouri have warmed into the low to middle 30s, with temperatures
in the 20s farther to the east across the area. A weak warm nose
has also spread over Kansas and as a result light rain is
occurring across portions of Kansas. The warm nose does not extend
much into Missouri so all snow is occurring farther to the east.
As the upper level low continues to spread south, temperatures in
the lower levels of the atmosphere will cool and the warm nose
should go away fairly quickly early this morning. As this occurs
any rain should turn over to snow, and any rain should be short
lived with this system with over all mostly snow occurring with
this system.

Snow will then slowly spread south and east across the area this
morning with lingering snow across southern Missouri into this
afternoon. Snow will generally range from around one to two
inches with localized amounts up to three inches, generally west
of Highway 65 where more of a west to east movement of the snow
will occur. Will continue the Winter Weather Advisory as is for
the entire forecast area through noon today. There could be
additional minor accumulations across far southern Missouri this
afternoon.

A much colder air mass will spread into the area today, which will
result in highs occurring this morning. Temperatures this
afternoon will fall into the teens with wind chills dropping to
around zero as gusty northerly winds occur behind the cold front.
Temperatures will fall to around zero tonight with wind chill
values of -10 to -20 expected. Will also continue the Wind Chill
advisory as is for the entire area tonight into Tuesday morning.

.LONG TERM...(Tuesday through Sunday)
Issued at 235 AM CST Mon Jan 15 2018

The cold air mass will remain over the area into Wednesday. Highs
on Tuesday will only warm into the lower to middle teens with lows
falling to around zero again Tuesday night. Winds will not be as
strong Tuesday night into Wednesday morning, so wind chills will
not be as cold as tonight. However, wind chills will still be able
to fall to -10 to zero. Highs on Wednesday will warm into the 20s
with highs in the 30s expected on Thursday.

An upper level ridge and warmer temperatures will spread into the
area late this week into the weekend as highs in the 40s and 50s
are expected. An upper level low will track across the Plains
late in the weekend sending a cold front and chances for showers
to the area. If enough moisture can return some isolated thunder
will not be out of the question with these showers.
