Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jun 21, 2:03 PM CDT, 1 hour 30 minutes before

Area Forecast Discussion
National Weather Service Goodland KS
103 PM MDT Sun Jun 21 2020

.SHORT TERM...(Through Tonight)
Issued at 1245 AM MDT Sun Jun 21 2020

As of 12:00 pm MDT, updrafts have begun to develop along the
dryline in Wallace/Logan counties. Thus far, updrafts have
remained relatively disorganized, however, as updrafts unzip
further east along the dryline -- in an increasingly unstable
airmass (mlcape 3500-4500 J/kg), damaging winds and large hail
will become increasingly likely. Expect activity to propagate ESE-
SE toward Garden City/Dodge City/Hays by 00Z.

.LONG TERM...(Monday through Sunday)
Issued at 102 PM MDT Sun Jun 21 2020

Daily chances for showers and storms are possible through the
weekend.  An upper trough will be over the High Plains and Central
High Plains Monday morning with northwest flow aloft over the Tri-
State area.  An upper ridge will be situated over the Western CONUS.
Showers and thunderstorms will be possible Monday and Tuesday as
embedded shortwave troughs move through the northwest flow into the
region.  Temperatures will range from the low to mid-80s for highs
both days.  Lows will be primarily in the 50s.

A lee trough is expected to develop on Wednesday with trough axis to
the west of the Kansas-Colorado border.  The ridge will begin to
flatten as it moves to the east, resulting in flow becoming zonal
Thursday night.  Showers and thunderstorms will be possible in the
afternoon and evening hours.  Temperatures will begin a gradual
warming trend Wednesday afternoon, returning to the upper 80s to low
90s.

Another upper trough will move across the Western U.S. Thursday
evening into Friday.  Flow will become southwest aloft over the Tri-
State area.  Showers and thunderstorms will be possible Thursday and
Friday.  The weekend is expected to remain dry for now with highs in
the 90s.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1145 AM MDT Sun Jun 21 2020

Although an isolated thunderstorm cannot be ruled out this
afternoon -- activity is anticipated to remain south and east of
the GLD/MCK terminals. NW winds will increase to 15-25 knots late

sunset this evening.
