FIRST ALERT: Severe Thunderstorm Threat Ended for Tonight; Another Round Thursday Afternoon into Thursday Night
Damaging Winds, Large Hail, Tornadoes and Heavy Rain All Expected
SIOUX FALLS, S.D. (Dakota News Now) -- The severe threat on Wednesday was short-lived and didn’t produce much in terms of warnings or damage. Another round of severe thunderstorms is expected for Thursday afternoon into Thursday evening.
THURSDAY: A few showers and thunderstorms are possible during the morning hours, but most of the morning into early afternoon will remain dry. After 3 PM, more thunderstorms are expected to develop along a cold front and severe weather is expected once again. A level three enhanced risk is in place for areas along and east of the James River, but chances diminish quickly west of there. Pierre and Mobridge are not under any risk of severe thunderstorms. The main hazards with this round of storms look to be large hail (some significant), damaging wind gusts that could be over 70 mph and tornadoes. The main window will be from 3 PM to midnight and models are indicating that tomorrow’s threat could be more widespread than it was Wednesday. Highs range from the 70s west to low 90s southeast with dewpoints in the 60s.
WEEKEND: Once the cold front moves through, the weekend is looking great. Friday will feature sunny to mostly sunny skies with a mostly sunny to partly cloudy sky. Some models want to show a few widely scattered showers at times over the weekend and while this could very well be possible, the airmass will be much drier and the coverage area will be 20% or less. Highs will be in the 70s Friday with mid 60s to mid 70s Saturday and Sunday.
