Area forecast discussion, Jul 2, 5:13 PM MDT, 29 minutes before
Area Forecast Discussion
National Weather Service Dodge City KS
613 PM CDT Mon Jul 2 2018

...Updated Aviation...

.SHORT TERM...(This evening through Tuesday)
Issued at 113 PM CDT Mon Jul 2 2018

Have the highest pops near the Colorado border for this evening.
There is a chance of storms in this area associated with upslope
flow. Main threats if storms do develop would be 60 mph winds and
up to 1" hail. The NMMB is fairly excited with storm development
and keeps activity going through the overnight across portions of
Kansas. Not totally sure this will happen given how weak steering
flow is. Still, will retain the slight pops in during the
overnight period as I cannot rule out an isolated overnight storm
entirely. Otherwise, a fairly quiet night is expected with lows in
the 60s and 70s.

.LONG TERM...(Tuesday night through Monday)
Issued at 113 PM CDT Mon Jul 2 2018

A dry forecast is forecast for Tuesday night as 500-hPa heights
rise in association with a building ridge axis developing over
the greater region. Highs tomorrow should peak in the mid to upper
90s.

The next chance of storms is Wednesday evening. Storms look to
erupt along a frontal boundary across Nebraska. Some of this
activity may drift across the northern zones. Otherwise, the rest
of the forecast area will remain dry.

Will have to watch out Thursday and Friday. The above mentioned
front may sag southward across the forecast area. This may lead to
isolated storms developing along the boundary. Along with the
higher chance of storms comes slightly cooler highs for the end
of the business week.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 611 PM CDT Mon Jul 2 2018

VFR conditions through the time period. Clouds above 15,000 ft
from dying storms in eastern Colorado into western Kansas will
overspread mainly GCK and LBL from 03Z-09Z...otherwise a generally
quiet time period weather wise.
