Area Forecast Discussion
National Weather Service Wichita KS
334 PM CDT Mon Mar 27 2017

.SHORT TERM...(This evening through Thursday night)
Issued at 330 PM CDT Mon Mar 27 2017

Lots of remnant low cloudiness across most of ern KS this afternoon,
as low level moisture has been stubborn to scour out, given the
limited drying/cold advection. Could see some breaks in the low
level cloud cover for the early evening hours, but highly
pessimistic that all the low level cloudiness will scour out
completely as the surface flow shifts back to the E-SE.

A series of slow moving storm systems will be the story, as the
progressive zonal flow and wide open gulf moisture return will lead
to a very showery week.

The first in the series of storms will make its way across the srn
Rockies on Tue with warm advection/low level moisture transport
increasing by Tue morning and especially by Tue afternoon. This
upper low will make very slow progress across the srn plains, with
the upper low becoming vertically stacked tue night across OK. This
will lead to off and on showers and embedded thunderstorms for most
of the forecast area through Thu morning. Models are fairly similar
in the track of the main surface low with this system, with both the
GFS and ECMWF keeping the surface low south of the forecast area
across srn OK. This will keep most of the forecast area on the north
side of the low, with abundant moisture wrapping northeast into most
of the area, with the heaviest showers expected to be across most of
southern Kansas.  Expect to see some healthy rainfall totals with
this system, given the precipitable water values of 150-200 percent
of normal, by Thu morning, with the periodic showers and storms.
With the abundant moisture in place, would not be surprised to see 2
to 4 inch rainfall totals by Thu morning, with the heaviest along
Highway 400 for areas east of the KS turnpike.

Given overall marginal instability and vertically stacked mid-upper
flow, widespread severe weather appears unlikely across the forecast
area throughout this rainfall event. Could still see a few strong to
low-end severe storms, especially over southern/southeast Kansas
Tuesday evening-night, and again on Wednesday.  MLCAPE values
approach 500-750 J/Kg along the KS/OK border with bulk shear of 70-
80 kts on Wed, which may lead to a sneaky marginal severe weather
chance on Wed morning.

.LONG TERM...(Friday through Monday)
Issued at 330 PM CDT Mon Mar 27 2017

The "highlight day" of the week looks to be on Fri, with this day,
expected to be between systems with light winds and seasonal temps.

Medium range models suggest that the next system will be quick on
the heels of the Thu system, arriving into the plains by early Sat.
Models suggest that system will make slow progress across the plains
as well, leading to a soggy weekend for most locations.  Some
uncertainty on the track of this system, but the latest GFS suggests
a similar path to the mid week system, which would again lead to off
and on showers and embedded thunder chance for Sat-Sun with
widespread cloud cover and east-southeast flow leading to max temps
a little below normal.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1255 PM CDT Mon Mar 27 2017

"Low-end" MVFR cigs wl cover all of Cntrl & SC KS the rest of the
aftn while IFR cigs cover SE KS til ~20Z when cigs would lift into
"Low end" MVFR Country. Optimism is lmt`d to KGBD & KRSL where
closest to the wrn periphery of MVFR Stratocu. Both terminals may
scatter out late this aftn. W/ an inverted sfc ridge, which at
issuance xtnd`d due S acrs Wrn KS, drifts E acrs Ern KS this eve,
NE 7-10kt winds would become lgt easterly acrs Cntrl & SC KS this
eve while SE KS would be lgt & vrbl due to alignment w/ the sfc
ridge.

.FIRE WEATHER...
Issued at 330 PM CDT Mon Mar 27 2017

Breezy east winds may support low-end very high grassland fire
danger across the region Tuesday morning. However, a limiting factor
will be increasing cloud cover and marginal afternoon humidity
values in the 40s-60s percent range. Otherwise, periodic showers and
embedded thunderstorms along with cooler temperatures should support
low fire danger levels the next several days.
