UPDATE - 10 P.M FRIDAY:
Hot and humid conditions will return this weekend with highs back into the middle and upper 80s. Dew points will stay steady in the upper 60s and lower 70s both Saturday and Sunday.
With the heat and humidity will come the chance for scattered showers and thunderstorms late Friday night through Sunday evening. It will be a tricky forecast this weekend because of how isolated storms will be through Sunday. Confidence is not high for widespread storm activity this weekend.
The first chance for showers and thunderstorms will be late Friday into early Saturday morning. Timing looks to be after 3 a.m for SE Minnesota and after 6 a.m for most of NE Iowa. Scattered showers will continue until around 9-10 a.m Saturday morning. New guidance suggests a more northerly track with this round of storms. Most storms should stay to the north of I-90 during the morning. NE Iowa might stay completely dry during the morning Saturday. Confidence remains extremely low with this round of storms.
The next chance for storms will come Sunday morning. Current guidance is suggesting a 7 a.m - 12 p.m time-frame for storms Sunday morning. There will be periods of dry time Sunday before a cold front moves through. There could be thunderstorm development along the cold front Sunday evening which would bring more rain to the area.
Current thinking is widespread severe weather does not look likely this weekend. Sunday afternoon and evening would be the best chance for a couple of isolated strong storms along the frontal boundary, but confidence is not high on that happening.
Temperatures will stay in the lower 80s through next Friday. Dry conditions are expected to start the weekend with scattered showers and thunderstorms possible Thursday into Friday.
Have a great weekend.
