.UPDATE...
Issued at 324 PM MDT Fri Aug 16 2019

...SEVERE THUNDERSTORM WATCH IN EFFECT TILL 10 PM MDT...

A severe thunderstorm watch has been issued for Goshen, Laramie,
and Platte Counties in Wyoming and for Banner, Box Butte,
Cheyenne, Kimball, Morrill, Scotts Bluff, and Sioux Counties in
Nebraska.

&&

.SHORT TERM...(This evening through Sunday)
Issued at 226 PM MDT Fri Aug 16 2019

Looks like one more round of storms late this afternoon into this
evening with some strong to severe storms expected as well. Most
likely areas for severe storms appears to be from extreme se Wy
across the southern Neb Panhandle where better instability should
exist. Does appear storms will exit the CWA by late this evening
leaving quiet conditions for the rest of the night.

A drying pattern should begin over the CWA on Saturday as more
westerly flow sets up over the area. Could be a few storms once
again over the plains but instability should be less so severe
threat more marginal. Quiet again Saturday night then even drier
air spreads in Sunday boding for a dry and very warm day.

.LONG TERM...(Sunday night through Friday)
Issued at 226 PM MDT Fri Aug 16 2019

An upper high will build a bit over the Co/NM border area early
next week keeping very warm and dry conditions in place Monday.
Chances for convection begin a return Tuesday as moisture begins
to increase from the south. Could see a backdoor cool front move
into the area later Tuesday through Weds which may increase
convection before a drier regime return for late in the week.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1020 PM MDT Fri Aug 16 2019

Wyoming TAFS...VFR. Wind gusts to 35 knots from 15Z to 01Z.
