AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
357 PM CDT Tue Jul 7 2015

.SHORT TERM...(This Evening through Wednesday)
Issued at 346 PM CDT TUE JUL 7 2015

Surface front currently extends roughly along the I-44 corridor into
a surface low over southwest Missouri. An MCV was also located
along the Red River in southwestern Oklahoma.

Convection had begun to move southeastward into Arkansas late this
morning but now appears to be edging slowly northward again over
eastern Oklahoma and western Arkansas.  The H8 winds to the south of
the frontal zone are still in the 20-30 kt range over this same area.

The surface front should continue to make its way southward to the
Missouri-Arkansas border by this evening before stalling out.  As the MCV
approaches the region tonight and the low level jet sets up again
this evening...training storms and resultant heavy rain will
continue overnight. The heaviest rainfall amounts should occur in an
area from the Missouri-Arkansas border to the I-44 corridor and
occurring between 1AM-1PM.

The focus of the heavy rain will gradually shift northward following
the front on Wednesday as the upper wave moves across and a surface
low moves up the front.  The axis of heavier rain will gradually
move north of the I-44 corridor over areas that have also seen
substantial rainfall.

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 346 PM CDT TUE JUL 7 2015

The surface front will remain in the area through Friday but an
upper level ridge begins to build in and retrograde to the west.
While rain is still in the forecast...current QPF is indicating
less than three-quarters of an inch from Wednesday night into
Friday.

Once high pressure builds in...will have a dry spell for the
weekend with a return to more seasonal temperatures. There will be
a chance for more rain toward the end of the forecast period as we
get into a northwest flow situation on the eastern side of the
upper level ridge.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon)
Issued at 1239 PM CDT TUE JUL 7 2015

MVFR and IFR conditions are expected through the period as low
level cloudiness and rainfall will cause ceilings and visibility
issues across all terminals. Light fog has developed behind a cold
front over the JLN terminals. SGF vis should decrease through the
afternoon as well as the cold front continues to sag southward.
LLWS is expected to increase, especially over the JLN terminal
during the mid to late morning hours tomorrow as LLJ strengthens.
