UPDATE (12:30 p.m.): Saturday's severe weather risk has been upgraded to "enhanced" for a large part of the state, including the Twin Cities. Flooding is also possible in the evening.
According to WCCO Director of Meteorology Mike Augustyniak, the severe threat is from mid-afternoon Saturday into the evening. Enhanced areas of severe weather could include 80+ mph straight-line winds, large hail and tornadoes.
MINNEAPOLIS (WCCO) -- According to WCCO meteorologist Riley O'Connor, the wettest part of Friday will be in the morning. Flash flood warnings for parts of the southeastern region of the state expired at 7 a.m.
Showers will become more scattered in the late morning and early afternoon. Temperatures will reach the mid-70s.
"We may even get a little sunshine," O'Connor said.
Things change into Saturday, with temperatures jumping up into the upper-80s and thunderstorms possible in the evening.
WCCO Director of Meteorology Mike Augustyniak says he's a bit concerned about urban and basement flooding in Hennepin and Ramsey counties, especially in the evening hours of Saturday.
Here are 2 possible outcomes for Saturday rainfall, from 2 different computer models. Because all models are wrong to some degree, neither of these are likely to be 100% right on the SPECIFICS of where the heaviest rain falls; but both point to the same GENERAL idea #mnwx #wiwx pic.twitter.com/llMYzJ9rdj

Sunday is expected to be sunny with less humidity.
Rainfall Is 'Great News' For Drought
Parts of the state had 2-4 inches of rainfall, and that's great news considering the drought conditions in the state.
The latest figures show that 88% of the state is still listed under severe drought conditions, and all but 3% of the state is under at least a moderate drought. Those figures haven't taken into account rain from this week, however.
Rain totals from the @WCCO Weather Watcher Network are GREAT news for the drought. Off/on rain continues for the next 36 hrs, ending with a dousing Saturday evening that could cause basement flooding. Details from @RileyOConnorWX thru 10a #MNwx #WIwx pic.twitter.com/4sKUE0f2ja
