What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Dodge City, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 23, 3:44 PM CDT, 2 hours 41 minutes earlier.

Area forecast discussion, Aug 23, 3:44 PM CDT, 2 hours 41 minutes before

Area Forecast Discussion
National Weather Service Dodge City KS
344 PM CDT TUE AUG 23 2016

...Updated synopsis, short term and long term discussions...

.SYNOPSIS...
Issued at 343 PM CDT Tue Aug 23 2016

A broad, weak upper level trough was in place over the mountains and
western states today while an upper level ridge extended from the upper
Midwest into the Deep South. Between these features, southwesterly flow
aloft was over the northern and central Plains states. Weak disturbances
embedded in the flow were located over Nebraska. At the surface, a cold
front extended south across the Dakotas into far northwest Nebraska
and then westward across Wyoming. A low pressure trough extended south
from the front across western portions of Nebraska and Kansas.

&&

.SHORT TERM...(This evening through Wednesday)
Issued at 343 PM CDT Tue Aug 23 2016

Abundant low level moisture returned to central and western portions
of Kansas overnight with mid to upper 60s dewpoints across the region.
Drier air was working its way back into southwest Kansas behind the
surface trough. By early afternoon the best low level moisture convergence
was setting up along a Coldwater to St John corridor. Visible satellite
imagery shows cumulus increasing in this area. Short term mesoscale
models have been consistenly focusing on convective initiation over
south central Kansas between 21-22z along the axis of better low level
moisture. Have bumped up pops across the south central zones late this
afternoon. Storms that develop should move fairly quickly off to the
east by early evening given the mean wind direction and speed over
the area.

The weak disturbance over the Four Corners region will move out into
the central High Plains later tonight. The models are hinting at some
shower activity moving out into west central Kansas overnight which
could continue into north central and northwest Kansas later tonight
and Wednesday morning. With that in mind, will keep some slight chance
pops going in my northwest zones overnight.

On Wednesday, the cold front slides farther south across western
Kansas. There could be a few lingering showers and thunderstorms
across the northern portions of the area along I-70 in the morning.
Showers and thunderstorms will increase during the afternoon hours
as the shortwave trough to the west moves out and interacts with the
frontal boundary. Temperatures on Wednesday will be a little
cooler than today across southwest and the area given increasing
cloud cover and the location of the front.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 343 PM CDT Tue Aug 23 2016

The shortwave is progged to move out over western Kansas Wednesday
evening. Thunderstorms should become a little more numerous along
the front into the evening hours. Precipitation may linger through
much of the night as upward vertical motion is enhanced over the
area by the right entrance region of an 80-90 knot upper level
jet. The front gradually slides farther south into southeast Kansas
and Oklahoma on Thursday. Will maintain some chance pops especially
across central/south central Kansas closer to the front.

An unsettled pattern appears to be in the works through the weekend.
A general trend in upper level southwesterly flow continues from
the southwestern U.S. A shortwave trough tracks east out of the
northern Rockies into the northern Plains on Saturday. This will
push anothern cold front down into the central High Plains Saturday
evening. Behind this system, upper level ridging builds into the
first part of next week. The models show a weak upper disturbance
slowly meandering across Kansas around Monday and Tuesday which, if
it pans out, could keep precip chances up through early next week.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1204 PM CDT Tue Aug 23 2016

Widely scattered thunderstorms are expected to develop after 21z
mainly over south central sections of Kansas. These storms should
stay east of the Dodge City and Hays terminals. There will be a
slight chance for thunderstorms over west central and parts of
southwest Kansas later tonight. There is some potential for these
to impact the Garden City terminal. Probabilities are low enough
at this time to preclude mentioning in the GCK TAF but this will
need to be monitored.
