Area forecast discussion, Jul 10, 1:40 AM CDT, 2 hours 5 minutes before
Area Forecast Discussion
National Weather Service Dodge City KS
140 AM CDT Fri Jul 10 2020

.SHORT TERM...(Today and tonight)
Issued at 113 AM CDT Fri Jul 10 2020

A few thunderstorms may develop after 2 am this morning as strong
elevated instability, adequate elevated shear and 40-50 kt high
level jet come together on the edge of the capping inversion. A
gradient in 700mb temperatures exist from northeast to southwest
from central into southwestern Kansas and this is where initiation
is expected. These storms could be severe with large hail. If the
storms develop into a line then damaging wind would be possible.
Temperatures will be held down today by low level southeast
upslope flow. Any morning convection to the south and east of here
will tend to shunt cool outflow back to the north and west with
the mean low level flow. Highs today ought to be mainly in the
90s, but if this morning's t-storms do not materialize then
readings would be a few degrees warmer, and possibly in the upper
90s to near 100 around Ashland and Coldwater.

.LONG TERM...(Saturday through Thursday)
Issued at 113 AM CDT Fri Jul 10 2020

A weak cold front will pass across western Kansas on Saturday and
this will again keep temperatures from reaching above 100 degrees.
Thunderstorms are unlikely Saturday or Saturday night as the
surface front should be well south of here and any convection
coming off the Rockies in weak NW flow should stay to the west.
However, there is a small chance of elevated convection late
Saturday night in far western Kansas. By Sunday there is a better
chance of afternoon convection over the western high plains
progressing into western Kansas Sunday night. Afternoon
temperatures Sunday should be mainly in the 90s again.

Thunderstorms can't be ruled out Monday and Tuesday as the mid to
upper level flow becomes more zonal, with a weak frontal boundary
persisting near the Oklahoma state line and plenty of low level
moisture lingering across western Kansas. In this summer time
regime, the thunderstorm forecast is highly dependent on previous
day's convection and exact location of frontal boundaries so that
detailed information is unknown. Continued very warm to hot
temperatures can be expected with mainly 95 to 100 for highs. If
the surface front is father north than expected then temperatures
could be above 100. However, given how the models have been over-
forecasting temperatures, staying on the low end is probably
prudent for now.

The upper level ridge that has generally been located across the
southern plains is expected to gradually shift northward by mid to
late next week. This will result in hotter and even drier weather,
with widespread afternoon temperatures over 100.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1254 AM CDT Fri Jul 10 2020

Elevated thunderstorms are expected to develop after 07z and could
effect KDDC/KHYS through 11z. The main concern with these storms
is large hail. High winds could be a threat if storms become
organized into a line. CIGS generally are expected to be AOA030
but any outflow that moves upslope toward 12 UTC could result in
lower CIGS. Upslope flow will persist until the end of the
period, with CIGS increasing to VFR with daytime heating.
