Area forecast discussion, Jun 8, 4:21 PM MST, 2 hours 34 minutes before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 521 PM MDT Fri Jun 8 2018 .DISCUSSION...(This Evening Through Friday) Issued at 210 PM MDT Fri Jun 8 2018 Current upper level analysis has broad ridging across the central CONUS with a couple of shortwaves topping the ridge across the northern Plains. Regional radar has a severe storm over the Black Hills at the moment, and additional storms in north central Wyoming. At the surface, weak low pressure is located across western SD with warm front south and east of the Black Hills. Low surface trof extends south into eastern Colorado. Temperatures at 2pm are in the 80s with winds out of the east to southeast. South-southeast winds to the south and east of the Black Hills will continue to keep 60s dewpoints in place across a good portion of western and south central SD, with 50s dewpoints elsewhere as winds switch to northerly across northeast WY behind the surface low. Plenty of energy available this afternoon, and most of the area is in the marginal to slight risk for severe storms, with an area of enhanced risk over portions of southwest into south central SD late today and this evening. The main threats from severe storms will be large hail and strong wind gusts, turning into more of a wind threat during the evening as the activity likely merges into a MCS somewhere toward central SD. There is also a minimal threat for tornadoes through early evening east of the Black Hills. Activity will eventually end overnight with lows in the mid 50s to mid 60s. Saturday will be another very warm day, with highs in the 80s to lower 90s. Frontal boundary looks like it will be in place from northeast WY to western and central NE. Plenty of moisture will remain to the northeast of the boundary. The ridge will shift east of the region as trof moves into the Pacific NW. Upper level support for storms does not look as favorable on Saturday, but cannot rule out isolated storms over the Black Hills in the afternoon and across much of western SD Saturday night as low level jet intensifies. Any storms that develop have the potential to be strong to severe with moisture remaining in place. As the upper level trof moves into southwest Canada late in the weekend, a cold front will push east across the Northern Plains Sunday night. Looks like most of the thunderstorm activity will stay north and west of the area, but isolated storms are certainly a possibility with the frontal passage. Ahead of the front on Sunday, highs will be in the 80s, with 90s to the east of the Black Hills. The cold front will bring much cooler and drier air for early next week as the upper trof passes to the north of the region. Highs look to mostly be in the 70s for Monday and Tuesday. Ridging is expected to build across the Rockies midweek and eventually move east into the Plains late week, bringing warmer air back to the region. The potential for at least isolated storms should return mid to late week. && .AVIATION...(For the 00Z TAFS Through 00Z Saturday Evening) Issued At 520 PM MDT Fri Jun 8 2018 Scattered strong to severe thunderstorms will continue across much of this area through the evening. Brief IFR vsbys within any thunderstorm. Otherwise, VFR conditions expected outside any storms. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...None. WY...None. && DISCUSSION...15 AVIATION...Johnson
