...Winter Weather Update...
Issued at 1228 PM CDT SUN MAR 16 2014
As is typical across southwestern Missouri, Mother Nature has
thrown us a bit of a curve-ball. We are getting what appears to be
convective elements with occasional loss of cloud ice from the
Springfield metropolitan area, south into eastern Christian
County and then east towards Ava. This has resulted in several
pockets of sleet.
This sleet will hold down snow amounts over parts of the Winter
Weather Advisory area...especially west of Highway 65 from the
Christian County line on north. We do expect the sleet to wane in
areal coverage over the next couple of hours with the overall back
edge of the precipitation also beginning to shift east into
western Missouri. The back edge of the precipitation will then
accelerate eastward from mid to late afternoon.
Overall, we are still expecting a swath of 1-3" snow amounts (with
some sleet) along the higher terrain of the plateau from far
eastern Greene and Christian Counties...east towards Salem and
Winona. Locally higher amounts around 4 inches remain quite
possible along the eastern portion of the plateau. No changes are
planned to the Winter Weather Advisory at this time.
As for the Wind Advisory, we were right at criteria about an hour
ago at Springfield. We do, however, expect winds to be on the
downswing over the next few hours. If this trend does indeed
occur, we will likely cancel the Wind Advisory early.
One final note that we want to get out there. With all of the
precipitation that has fallen and temperatures expected to fall
into the teens tonight, it is quite possible that refreezing on
roadways will occur...despite the precipitation coming to an end
by early this evening.
All public and hazardous weather products have been updated to
reflect the latest expectations.
.SHORT TERM...(Today and Tonight)
Issued at 400 AM CDT SUN MAR 16 2014
An area of showers has developed across western Missouri and
eastern Kansas to the southwest into Central Oklahoma and to the east
across southern Missouri and northern Arkansas early this morning.
The Rainfall has yet to spread into central Missouri but will in
an hour or two, with widespread rainfall occurring across the
entire area. The heaviest rainfall will occur generally along and
east of Interstate 49 and south of highway 60 where total
precipitation amounts of 1 to 2" of rainfall are still expected.
With the slower onset to precipitation across central Missouri
amounts will be less with a quarter to half inch of total
precipitation expected in these locations.
This precipitation is developing ahead of a slow moving storm
system across Oklahoma and Texas and north of surface low
pressure currently pushing east into western Arkansas early this
A cold front also located across the western and northern portions
of the forecast area early this morning. The front is located from
south to north across the Interstate 49 corridor then turns to the
east across the Highway 54 corridor. Temperatures south and east
of this front are in the 50s early this morning as temperatures
right behind the front are in the 40s. The real cold air associated
with this front is lagging slightly behind the front, but is
quickly spreading south across northern Missouri early this
morning. The front will track south through the entire area by the
mid to late morning hours. Temperatures will drop through the day,
and will quickly fall through the 30s and then into the 20s this
afternoon as the precipitation comes to an end from northwest to
The pressure gradient is tightening across the area and northerly
winds will increase and become quite gusty during the morning hours.
Sustained winds of 25 to 35 mph with gusts up to 45 mph can be
expected behind the cold front this morning. Winds will begin to
gradually weaken this afternoon as the cold front and surface
low track off to the southeast of the area allowing the pressure
gradient to slacken. Winds will however remain breezy through the
afternoon hours. Will keep the Wind advisory going as is until 6 pm
today, but with winds expected to gradually weaken this afternoon
the advisory may be able to be canceled earlier across some
The rain will begin to change over to snow from north to south
this morning into early this afternoon as the colder airmass slams
into the area. This airmass is deep enough that is should easily
push the the warm nose to the south through the area with the
colder airmass. This will result in rain mixed with and quickly
changing over to snow from north to south this morning into this
afternoon. There could be a very brief period of rain with surface
temperatures at the freezing mark right as temperatures drop to
freezing. This will be very brief and with current temperatures in
the 40s and 50s do not expected any rain to freeze as
the ground will have to have some time to cool. So, will keep any
mention of freezing rain out of the forecast.
The snow will occur across the entire area and will be moderate to
even heavy in nature at times. Around one half of an inch to near one
inch of snow accumulations will be possible, with a heavier band
still expected to develop along and southeast of a Cassville to
Bolivar to Rolla Missouri line where 1 to 3" with locally higher
amounts are expected. Its to note with the higher sun angle of mid
March and warm ground from the recent warm days we have had, most
of this snow accumulation will occur on grassy and elevated
surfaces as a lot of the snow will melt on contact with the
ground. To get accumulations on roadways, high snow rates will be
needed which will be possible where the higher snow amounts are
expected. Will continue the Winter Weather Advisory through this
afternoon and will also add Dade, Lawrence, Barry, and Stone
counties to the advisory. Temperatures will generally be in the
lower 30s while the snow is falling and once the snow begins to
taper off this afternoon temperatures will then fall into the 20s.
Lows tonight will fall into the middle teens to lower 20s, with a
few locations possibly dropping into the lower teens. These colder
temperatures and northerly winds will allow wind chill values to
drop into the single digits tonight.
These cold temperatures and wet roadways may result in some black
ice potential tonight into Monday morning.
.LONG TERM...(Monday through Saturday)

After the colder temperatures today and tonight, temperatures will
warm right back into the 50s on Monday then into the 60s on
Tuesday as upper level ridging builds east into the region. A dry
airmass will spread into the area tonight and will remain over the
region into early in the work week. As southerly winds increase
and usher the warmer temperatures in the region on Tuesday some
elevated fire weather conditions could develop, especially those
areas that do not receive as much precipitation today.
An upper level trough will track east across the northern plains
into the Great Lakes region on Wednesday. Moisture return will be
limited ahead of this system and not expecting any precipitation
associated with it. Temperatures will cool slightly on Wednesday but
will quickly warm back up to above normal for the end of the week.
Another upper level disturbance and associate cold front will push
through the region late this week and may bring some light rain to
.AVIATION...(For the 12Z TAFS through 12Z Monday Morning)
Issued at 554 AM CDT SUN MAR 16 2014
A Variety of aviation hazards will affect the terminal locations
today. Winds have already become strong at JLN/SGF with 20 to 30
kts and this is also expected at BBG in a few hours from the onset
of this set of TAFS. IFR conditions have already impacted the TAF
sites and should continue into the afternoon hours. Rain will
change over to snow as cold air rushes in from the north this
morning. Have this changeover occurring between 14-17z. Winds
should improve by mid to late afternoon along with the snow ending
and rising ceilings. VFR conditions are expected this evening.
