Area forecast discussion, Jun 20, 10:01 PM MST, 42 minutes before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 1101 PM MDT Tue Jun 20 2017 .DISCUSSION...(This Evening Through Tuesday) Issued at 256 PM MDT Tue Jun 20 2017 Current surface analysis shows stationary front near the Black Hills, with high pressure centered over northeast ND. Upper level analysis continues to show high pressure centered over eastern AZ, with ridging to the north across the intermountain west. Northwest flow aloft is in place across the Northern Plains. Skies are mostly sunny across much of the area. Temps range from the upper 70s across far northwest SD to around 90 over portions of northeast WY and far southern SD. Winds are variable and mostly on the lighter side across the area. There still could be a shower or thunderstorm developing across parts of far northeast WY and the northern Black Hills area late this afternoon near the boundary. Otherwise, the main chances for showers and storms should hold off until this evening when main shortwave energy and cold front approach the area. Precipitation chances will increase across northeast WY this evening and then spread east across much of the area overnight. Southerly low level jet will strengthen overnight east of the Black Hills, with modest theta-e advection over central SD. Could see a stronger storm or two over western areas in the evening, then possibly a strong to severe storm later tonight to the east of the Black Hills, near the nose of the low level jet. Gusty winds and hail will be the main threats from any stronger storms. Activity will exit eastern portions of the CWA late tonight/early Wednesday. Cold front over the Pacific NW will move quickly across the Rockies tonight and into western portions of the area Wednesday morning before stalling out over western SD during the day. Highs on Wednesday will range from the lower 80s over the Black Hills to near 95 over south central SD. A thunderstorm is possible over the Black Hills in the afternoon. Another round of nocturnal convection is possible Wednesday night as a weak disturbance aloft passes across and eventually pushes the front east of the forecast area by Thursday morning. Isolated strong to severe storms are possible near and east of the front from southwest to central SD. We will see a cooling trend for the rest of the week and into the weekend, with Friday and Saturday being the coolest days. A shortwave and Canadian cold front will slide southeast through the area late Friday into Saturday, bringing a chance of showers and a few storms. Mainly dry weather and warmer air will return late in the weekend and early next week. && .AVIATION...(For the 06Z TAFS Through 06Z Wednesday Night) Issued At 1058 PM MDT Tue Jun 20 2017 VFR conditions will prevail outside of TSRA through Wednesday. Isolated to scattered TSRA will occur overnight, mainly east and north of the Black Hills. Local MVFR conditions possible in/near any storms. A period of gusty northwest winds are expected late tonight through midday Wednesday behind a cold front. Additional storms may develop as another disturbance moves through Wednesday night. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...None. WY...None. && DISCUSSION...26 AVIATION...Helgeson
