A powerful storm system Friday into the weekend will need to be watched for severe weather potential. Clashes of cold air and warm air meet very close by with widely varying conditions noted over short (100 miles or less) distances in this timeframe. That distance could be make or break for the going forecast and how severe weather plays out locally.
A slowly moving cold front moves southwards on Thursday and lays up over central Iowa for Friday. Slowly trying to nudge back up during the day as a warm front, it will get back into northern Iowa on Saturday. Given the southward push, most of the severe weather risk stays to our southwest on Friday with more a cool, gray and wet vibe playing out over the local area. But if a push northwards materializes, some of that better thunderstorm energy will be at our disposal. Check out the temperature difference over short distances from Rochester to Clarion, nearly 30°!
Saturday holds the best chance for strong/severe storms popping up locally as that front shows signs of popping back northwards.
But it all hinges on that front and where it sets up. On the north side of it, as currently forecast, we'll call for much cooler conditions and much less of a severe threat than some neighbors to the south in central/western Iowa. The current 7-Day plays more of a middle ground as to how it pertains to the temperatures. Soaking rains look likely regardless of severe risk.
