.DISCUSSION...(This Evening Through Wednesday)
Issued at 220 PM MDT Wed Jul 24 2019

Current surface map places trof across northeast Wyoming, with
cold front moving into central Montana. Water vapor shows
shortwave ridging across western South Dakota, with upper trof
across the Canadian rockies into western Montana/Idaho. A few
thunderstorms trying to go across the northern Black Hills, but
have struggled with ongoing subsidence/strong cap. Environment
becomes more favorable as upper ridge shifts eastward over the
next few hours and weak impulse crosses the area later this
evening. With MLCAPE of 1500-2000 J/KG across much of western
South Dakota and increasing shear, a few supercells possible.
Strong/severe winds will be the main threat with DCAPE greater
than 1200 J/KG. Sustained/rotating updrafts will be capable of
large hail. Thunderstorms shift into central South Dakota late
this evening/overnight. Cold front will reach northeast
Wyoming/northwest South Dakota 04z-06z and slowly move through the
remainder of the area overnight. Some lingering convection
expected across south central South Dakota late tonight/early
Thursday morning. A period of breezy northwest winds sill arrive
behind the cold front. Will be dry across much of the area on
Thursday. Other than the potential for early morning convection
along the front in south central South Dakota, isolated storms
possible Thursday afternoon over the southern Black Hills.

Upper trof moves into the western Great Lakes on Friday with
northwest flow over the northern plains. Isolated
afternoon/evening thunderstorms possible over the Black
Hills...with chance thunderstorms extending into south central
South Dakota Friday night. Stronger shortwave crosses the northern
plains Saturday, with a better chance of thunderstorms. Upper
level high remains across the southwest CONUS early next week,
with flat ridge over the northern plains. Several ridge riding
impulses will cross the northern plains resulting in a daily
chance of thunderstorms. Temperatures will be near to slightly
above average

.AVIATION...(For the 00Z TAFS Through 00Z Thursday Evening)
Issued At 512 PM MDT Wed Jul 24 2019

A cluster of TSRA will move across the area this evening with
local IFR conditions in the strongest storms, some of which may
be strong/severe with hail/strong winds. A cold front will move
through early Thursday morning bringing gusty northwest winds over
the northwest SD plains.
