Area Forecast Discussion
National Weather Service Dodge City KS
234 PM CDT Sun Aug 20 2017


.SHORT TERM...(This evening through Monday)
Issued at 226 PM CDT Sun Aug 20 2017

 Broad plume of 14 deg C 700 mb level air was located from eastern
Colorado through southwest Nebraska and northwest/west central
Kansas this afternoon. The last couple of forecast updates showed
the shortblend model consensus maintaining afternoon highs around
100 degrees though the I-70 corridor and broad weak southwest
surface flow. The NAM indicated no convective precipitation this
evening. Otherwise, the RAP/HRRR models do appear to develop
isolated convection near the edge of the mid level cap. In any
case, the convective environment is not that impressive with very
weak deep shear overall. We do not expect to alter the low POPs
this evening. Gong forward into the evening and overnight, the arc
of thin cirrus should become more dense with time as the
shortwave spinning over west central New Mexico will track
northeast into southeast Colorado by Monday morning. A moderate
mid level moisture transport signal should develop by midday
Sunday. Although not a much better severe weather risk, but
frequent lightning and locally heavy rain risk as the shortwave
becomes sheared out into the Missouri valley late Monday night.
The cloud cover and rain chances should lead to about a 10 degree
high temperature drop by mid afternoon, as compared to today, with
especially cooler evening temperatures.

.LONG TERM...(Monday night through Sunday)
Issued at 226 PM CDT Sun Aug 20 2017

By Tuesday morning the models hint at a slug of low level stratus
behind the cold front, covering most of far southwest Kansas in
overcast before mixing out by late afternoon in light east-northeast
surface flow. This appears to be at least a couple of days with
minimal chances for storms in the area given a lack of significant
moisture return. Model consensus delivers highs just around 5
degrees below normal for late August with rain and thunderstorm
chances returning by the weekend.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 226 PM CDT Sun Aug 20 2017

The TAF area should experience an overall increase in high level
cirrus cloud cover today, surface wind fairly steady between 10
and 14 knots through the period with a cease in any occasional
20kt gusts by 23Z.
