Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
524 PM MDT Fri May 27 2022

.DISCUSSION...(This Evening Through Friday)
Issued at 1236 PM MDT Fri May 27 2022

Water vapor shows upper ridge axis over the Northern Plains with
upper trof working into the western CONUS, and distinct wave over
the Northern Rockies. At the surface, broad trof over eastern
MT/eastern WY with best pressure falls over western SD. Temps are
generally in the mid 70s to mid 80s early this afternoon, with
fairly abundant mid/high clouds holding temps down a bit.

Surface low expected to form this afternoon over far western SD
invof the Black Hills per best pressure falls. MLCAPE will be in the
500-1000J/kg range along the surface trof and especially north of
the surface low into northwest SD. Best chance for showers/storms
will be in the late afternoon to early evening time frame mainly
along/north of I-90 in northeast WY, the Black Hills and northwest
SD. Given the dry low levels and higher LCLs, main concern with any
storms will be wind gusts given DCAPE aoa 1000J/kg. It's possible
that MLCAPE may not reach its full potential given the amount of
mid/high clouds, but that remains to be seen. Activity should
quickly push out of the area by mid evening.

Stronger wave arrives Saturday, with better moisture in place
near/east of the Black Hills given inverted trof extending north
into far western SD. MLCAPE should be a bit higher than today given
increased low level moisture, and shear profiles combined with CAMs
output suggest several bowing segments possible with storms,
especially near/south of I-90 in western SD. Large hail also a risk,
particularly with more discrete supercells. Given rather high PW's,
heavy rains also a possibility. Temps should be wide ranging from
west to east given inverted trof.

Upper low forms over southern ID on Sunday and shifts into the
Northern Plains on Monday, a bit more of an easterly track than
previous model runs suggested. Looks like best potential for
widespread precip will be in the Sunday night and Monday time frame.
There is some chance for a severe threat on Sunday in our eastern
zones, and will be dependent on position of frontal boundary. PWs
will be remain high with potential for heavy rains at times. Upper
low/trof should shift east of the area on Tuesday.

Drier and warmer conditions will returns for mid/late next week,
although west/northwest flow will lead to some chances for precip at
times.

.AVIATION...(For the 00Z TAFS Through 00Z Saturday Evening)
Issued At 524 PM MDT Fri May 27 2022

Isolated to scattered showers and thunderstorms are developing
ahead of and along a cold front now crossing western SD. Very
gusty winds are expected within storms and just behind the frontal
boundary. Local and brief MVFR conditions are possible in and
near any stronger storms. Conditions will become VFR late this
evening as the storms exit to the east.
