Lightning Strike in Kansas, October 9, 2017

Area Forecast Discussion
National Weather Service Wichita KS
323 PM CDT Mon Oct 9 2017

.SHORT TERM...(This evening through Wednesday night)
Issued at 316 PM CDT Mon Oct 9 2017

Interesting late afternoon and early evening severe setup, as
surface low over central OK makes slow progress straight east across
nrn OK for the afternoon hours. The main surface synoptic cold front
attached to the low, currently over the eastern half of the Wichita
Metro area, basically along the KS Turnpike. Low level moisture
continues to increase just ahead and to the northeast of the low for
areas east of the KS turnpike and south of Highway 54. MLCAPE values
along the KS/OK border have climbed into the 1000-1500 J/KG range,
with surface dewpoints climbing into the mid 60s. Highest
instability is along the KS/OK border.  As the late afternoon
continues the vigorous shortwave currently over Central Co will move
out into the high plains, with bulk shear increasing across the
plains to 60-65 kts across most of south central KS and southeast
KS. Placement of the warm front and northward progression of the low
level moisture will be critical to placement of severe potential for
the late afternoon and early evening hours.  The combination of the
instability and shear suggests severe producing supercells are
possible for areas east of the KS turnpike into the evening hours.
The main concern will mainly be very large hail and damaging winds,
as 0-1km CAPE in only around 200 j/kg.  But directional shear and
curving hodographs suggests that a tornado or two cannot be ruled
out at least through sunset, primarily along the KS/OK border.

Could also see a few elevated severe storms to the north of
the cold front across portions of central KS given the increasing
steep lapse rates and bulk shear into the evening hours.

Gusty post frontal winds will also increase across much of south
central KS for the evening hours, with some gusts to 45 mph
possible, so will go with a wind advisory this evening for much
central and south central KS as the front pushes SE.

The strong cold front will make its way across most of the
forecast area overnight, with lingering showers expected across
most of central KS into Tue morning as the main cold core
shortwave pushes across central KS by Tue morning. As the front
pushes south, expect to see well below normal temperatures
(ie...chilly temps) push south across the region with high temps
on Tue only in the low 50s.

Cooler than normal temps will be the main story for Tue-Wed as the
cool Canadian surface ridge of high pressure makes its way across
the area.  As the ridge moves over. expect ideal radiational cooling
conditions with light winds and clear skies possibly leading to
areas of frost over portions of central KS by Wed morning as low
temps fall into the middle 30s.

.LONG TERM...(Thursday through Monday)
Issued at 316 PM CDT Mon Oct 9 2017

The chilly temps will be short lived, as warmer temperatures will
quickly return to the region for Thursday-Saturday as southerly
winds push warmer air northward across the central plains.  Medium
range models suggest another shortwave will move across the northern
plains late Fri or Sat with chances of shower and storm chances
returning to the region.  Still some timing differences on when the
shortwave will move across, but both the GFS and ECMWF show another
strong front pushing southeast across the area for late Fri night or
early Sat.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1241 PM CDT Mon Oct 9 2017

A strong cold front will continue to slice southeast across the
region this afternoon and tonight. Behind the front, strong north
winds and MVFR ceiling are expected. Ahead of the front, scattered
thunderstorms will prevail over southeast Kansas after 3 pm, some
of which may be severe. Scattered to numerous showers and
thunderstorms will expand across much of the area this evening and
overnight, as a strong upper disturbance approaches from the west.
