Area Forecast Discussion
National Weather Service Wichita KS
1154 PM CDT WED SEP 7 2016

.UPDATE...
Issued at 822 PM CDT Wed Sep 7 2016

Despite a subtle upper wave currently progressing northeast
across south-central KS amidst a very moist and moderately
unstable airmass, scattered showers/thunderstorms have yet to
materialize across the forecast area. Activity has actually proved
most widespread northeast of the forecast area, where it appears
combination of best 850-700mb warm advection and moisture
transport reside.

While a few showers/thunderstorms cannot be ruled out across the
forecast area before midnight, anticipating a gradual uptick in
thunderstorm coverage after midnight across mainly south-
central/southeast KS, as various short-term guidance increases
moisture transport/warm advection from the southwest, possibly in
response to the favorable right entrance region of a strong upper
jet coming overhead. As previous forecaster mentioned, main threat
with the strongest activity will be locally intense rainfall rates
due to near record high precipitable waters, which may lead to
pockets of flash flooding.

&&

.SHORT TERM...(This evening through Saturday night)
Issued at 223 PM CDT Wed Sep 7 2016

A plume of tropical moisture continues to stream over the Central
Plains as seen on the latest water vapor satellite imagery while a
subtle shortwave trough was lifting northeast toward the area.
This should support scattered storm development late this
afternoon and evening within a weakly capped airmass. 12Z area
soundings indicated a very moist column with PWATS around 2 inches
while the current SPC Mesoscale Analysis page suggests PWATS have
risen into the 2-2.2" range which will support the potential for
efficient rain production and flooding with any storms that
develop during the evening and overnight hours. The highest
probabilities are expected to remain across southeast KS where the
best H85 moisture transport is anticipated.

Low lvl moisture transport/310K isentropic upglide is progged to
persist Thu-Fri supporting periods of showers and thunderstorms
across much of the area through the period although the highest
probabilities are expected to remain across southeast KS. Limited
insolation will keep temperatures at or below climate normals
through the period. More widespread storm activity including flash
flooding and a few severe storms will arrive on Friday afternoon
and Friday evening along a southward advancing cold front.

Saturday...A stable post-frontal regime is anticipated on
Saturday as surface high pressure builds across the area. Light
winds, clear skies and seasonably cool temperatures in the 70s are
expected with a much drier continental airmass entrenched across
the region.

.LONG TERM...(Sunday through Wednesday)
Issued at 223 PM CDT Wed Sep 7 2016

Low level southerly flow will return to the Central Plains states
on Sunday with dry weather conditions and moderating temperatures.
Another chance for storms will arrive on Monday as a shortwave
trough moves over the Northern Plains and drives a cold front
south across the area. This front will remain in the area on
Tuesday & Wednesday providing a focus for showers and
thunderstorms. Temperatures in the wake of the front will fall
below normal once again with highs on Wednesday only reaching the
low to mid 70s.

&&

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1154 PM CDT Wed Sep 7 2016

Expecting scattered thunderstorms to fester much of the night
mainly southeast of Salina to Great Bend, as a cold front slowly
approaches from the northwest, interacting with a very moist and
moderately unstable airmass in place across the region. Thinking
this activity will gradually expand/spread into mainly south-
central/southeast KS during the day Thursday.
