Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 445 PM MDT Fri Jun 15 2018 .DISCUSSION...(This Evening Through Friday) Issued at 151 PM MDT Fri Jun 15 2018 Upper-level analysis shows a trough over the Pacific Northwest, and ridging over much of the central/eastern CONUS. Skies across the northern plains are mostly sunny, although radar is picking up on some storms across WY and MT. Surface low over eastern SD and high pressure to the west are keeping winds generally northerly across western SD, but southeasterly across northeastern WY. Temperatures are rising into the 70s and 80s. A shortwave will move through southwest flow into the northern plains this evening. Strong frontogenesis across northeastern WY will support showers and thunderstorms, with severe storms possible, given excellent 0-6 km shear around 60 kts and sufficient instability. Better instability will be farther east, but the forcing isn't as strong there. Besides strong winds and large hail, tornadoes will also be possible: LCLs decrease below 1 km, and 0-1 km helicity and shear increase to near 300 m2/s2 and 20+ kts, respectively. CAMs show storms beginning across northeastern WY around 23-00Z, then spreading across western SD during the evening. Although the greatest potential for severe weather this evening will be across northeastern WY, storms spreading into SD could also be strong to severe, especially with the increasing instability to the east. Chances for showers/storms will linger into Saturday, but the main energy will be to the north of the CWA during the day. Towards the evening, another shortwave is progged to push into the area from the southwest. Thinking the best chance for severe weather will be across south central SD, where MLCAPE is expected to reach 2000-3000 J/kg, and 0-6 km shear will be around 40 kts. Positive theta-e advection may allow storms to persist well into the night. With precipitable water reaching 200% of normal, some heavy rain will be possible with these storms as well. Energy will continue to move into the region Sunday ahead of the west coast upper low, and precipitation will persist across much of the CWA. Isolated thunderstorms will be possible, but it should be mostly just rain showers. From tonight through Sunday night, models are showing 1 to 2 inches of precipitation possible, with some areas approaching 3 inches. Later shifts may consider a flood watch. Highs Sunday will be mainly in the 60s. After a cool and wet weekend, temperatures will gradually start to warm up next week. The ECMWF shows the upper low spinning over the western CONUS through the entire week, whereas the GFS has it weakening into an open trough as it finally shifts eastward. Either way, expect daily chances for showers/storms next week. && .AVIATION...(For the 00Z TAFS Through 00Z Saturday Evening) Issued At 444 PM MDT Fri Jun 15 2018 Scattered TSRA will develop this evening across northeastern Wyoming, then expand and move eastward across western South Dakota. Widespread MVFR CIGS/LCL IFR CIGS will develop over northeastern Wyoming, and most of western South Dakota after 09Z tonight and will improve to VFR at most locations around 18Z on Saturday. && .UNR WATCHES/WARNINGS/ADVISORIES...
