AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1222 PM CDT Mon Apr 21 2014

.SHORT TERM...(Today and Tonight)
Issued at 310 AM CDT MON APR 21 2014

An upper level trough is currently pushing across the southern
Plains early this morning. Showers and a few thunderstorms are
developing ahead of this feature across portions of Oklahoma,
eastern Kansas, and far western Missouri and Arkansas. Showers
with embedded thunderstorms will continue to develop and track
across the region through out the day today as the upper level
trough tracks east across the region. This activity will develop
on and off throughout the day. Shear and instability will be weak
enough where no severe weather will occur. A cold front will also
push south through the region this evening into tonight allowing
for scattered showers and thunderstorms to remain possible during
the evening hours. The rain will exit the area by around midnight
tonight.

.LONG TERM...(Tuesday through Sunday)
Issued at 310 AM CDT MON APR 21 2014

The airmass behind this front will not be much cooler as highs
will still top out in the lower to middle 70s Tuesday afternoon
under sunny skies. Upper level ridging will build over the region
on Wednesday as highs warm into the middle to upper 70s. Southerly
winds will increase and become breezy and gusty on Wednesday. Drier
conditions will spread into the area behind the cold frontal
passage this evening. The southerly winds will help to pull
increased moisture into the region, but this moisture return will
be slow across the eastern Ozarks during the day on Wednesday. The
combination of increased southerly winds and dry conditions
will result in elevated fire weather conditions Wednesday
afternoon across the eastern Ozarks.

An upper level low is then expected to push east into the northern
Plains by Wednesday night and then into the Great Lakes region by
Friday. A cold front will push across the Plains on Wednesday into
Wednesday night ahead of the upper level low. Thunderstorms are
expected to develop across western Kansas south into Texas late
Wednesday afternoon into Wednesday evening. These storms will then
form into a complex of storms across central Kansas Wednesday
night and push east towards the area late in the night into
Thursday morning. This activity will then push across the area
Thursday morning into the early afternoon and will push east of
the area during the afternoon hours. The timing of these storms
should result in instability not to be able to increase with the
heating of the day and should limit the strong to severe potential
with this activity.

The front will push south into southern Arkansas Thursday night
into Friday. The front will then slowly lift back to the north as
a warm front Saturday into Sunday. The medium range models differ on
how quickly and how far north the front tracks back to the north
this weekend. An upper level low will also dig into the southwestern U.S.
this weekend and energy from the low and the warm front will be
the focus for shower and thunderstorm development this weekend.
Still too far out to pin out the exact locations of the front
during this time, especially with the model inconsistency. The
front will be over or near the area this weekend resulting in
chances for showers and thunderstorms.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 1209 PM CDT MON APR 21 2014

For the KSGF/KJLN/KBBG TAFS...MVFR conditions exist across the
region at this time with isolated IFR here and there. Surface cold
front extends from about KFNB-KICT-KWDG at this hour. Most of the
rainfall activity is located from northeastern OK into southwestern MO.

Expect MVFR conditions to prevail through the afternoon hours
until the front pushes through between 00-02z. Kept VCTS in for
convective activity just ahead of the front. Could occasionally
see isolated IFR ceilings with some of the convective
activity...but probability is not high enough to include in the
TAFS.

Once the front passes...conditions should improve to VFR with a
mid layer cloud deck. Expect clearing skies after 06z with light
northwest winds through the remainder of the TAF period.
