Area Forecast Discussion
National Weather Service Wichita KS
619 PM CDT Sat Apr 29 2017

.SHORT TERM...(This evening through Tuesday night)
Issued at 304 PM CDT Sat Apr 29 2017

Main forecast focus is the ongoing storm system.

Showers and thunderstorms continue across the eastern portion of
the CWA. Ongoing convection remains below severe levels. Would
argue that some of these could be strong with the shear/buoyancy
combinations, but the most significant threat is well to the east
of the area.

The main focusing mechanism for the convection across southeast
Kansas is an inverted trough which extends north of a low which
was centered over eastern Oklahoma. Satellite/radar/observations
show a back edge to the main area of convection which extended
from about OKC-ICT-MCI. This should continue moving east as the
system.

One thing of note was that on the back side of this trough, there
was a small mesoscale area of northeast winds gusting over 40
knots. This was noted on the WSR-88D where winds exceeding 50
knots were observed. This was very localized and at the moment and
is not seen in the observations.

Well behind this area of precipitation, a second area of forcing
and associated precipitation extends across western Kansas. Much
of this is snow with significant accumulations. This forcing is
associated with the main PV anomaly which is well back across the
4 corners region.

This is significant since the main forcing does not move across
the state until late tonight through morning Sunday. This means
that there remains very high confidence in significant
precipitation across the state through Sunday. Of note here this
the forcing depicted with this storm is one of the more prolific
Q-vector convergence signals that I have seen.

As the storm exits, enough cold air will be brought into the CWA
for snow to fall in central Kansas. This should accumulate along
and north of a line from Salina to Great Bend. Accumulations right
now are expected to be an inch or less.

The flood watch looks in good shape. Have received reports of over
2 inches or rainfall across the southern and eastern portion of
the CWA. Many ditches are running full but no flooding has been
reported. We expected an additional 2-3 inches of rain through the
remainder of the storm, so flooding is still possible, and likely
along the rivers in that part of the state.

Storm Bottom line: very high confidence in additional
precipitation, fairly high confidence in snow across central
Kansas with an inch or less of accumulation. Good confidence in
receiving about 2-3 inches across southeast Kansas. Storm should
exit the region Sunday night.

The next problems to deal with are the wind and low temperatures
Sunday night. Strong cold advection behind the front will push
temperature down toward freezing Sunday night across central
Kansas. Will have to monitor, but no frost expected with the
amount of wind expected. Soundings suggest enough momentum
transport for wind advisories Sunday afternoon and evening across
central Kansas.

.LONG TERM...(Wednesday through Saturday)
Issued at 304 PM CDT Sat Apr 29 2017

The main challenge here is the system moving through the region
Wednesday. The ECMWF/GFS runs today trend further south and east
with the precipitation. And while that storm system does take a
similar track, the associated upper level disturbance is not
nearly is vigorous. This means less forcing and less
precipitation. Confidence is moderate at receiving additional
precipitation, higher for southeast Kansas. Severe storms do not
look probable at this time.

&&

.AVIATION...(For the 00Z TAFS through 00Z Sunday evening)
Issued at 615 PM CDT Sat Apr 29 2017

Low clouds with periods of light rain/drizzle will continue to
affect central/south central Kansas through the night. Meanwhile
numerous showers and a few thunderstorms will move northeast
across southeast Kansas. Colder air will spread east towards
central Kansas by Sunday morning which could change the rain over
to snow for RSL/GBD sites.

355 PM CDT Sat Apr 29 2017

This hazardous weather outlook is for portions of Central Kansas,
South Central Kansas and Southeast Kansas.

.DAY ONE...Tonight

Widespread showers and thunderstorms will impact the region
tonight. Pockets of minor flooding of low-lying and flood-prone
areas are possible areawide. However, southeast Kansas has the
greatest potential to see heavy rainfall rates and associated flash
flooding concerns, along with a few strong to severe storms with
large hail.

Snow may mix with the rain late tonight across Russell and Barton
counties, with light slushy accumulations possible on grassy
surfaces.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Snow with a mix of rain will occur Sunday across areas along and west
of Salina, Ellsworth, and Great Bend. Up to one inch is possible on
grassy surfaces.

Minor low-land flooding will remain possible across central and
north-central Kansas Sunday due to persistent rain much of the day.

Healthy rises are expected on most area rivers and streams due to
the widespread rain. A flood warning has already been issued for
parts of the Neosho river from Erie south through Oswego. Depending
on how much rain occurs, additional rivers may eventually exceed
flood stage as well. The greatest likelihoods include the Cow Creek
northwest of Hutchinson and the Arkansas River near Arkansas City.
Check the latest flood warnings and statements for the latest
details.

Thunderstorm chances will return late Tuesday into Wednesday. While
widespread severe weather appears unlikely, a few strong to
marginally severe storms cannot be ruled out over mainly southern
Kansas.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated tonight. However, rainfall
totals are greatly appreciated!
