String of 80 degree weather comes with a little more humidity

Temperatures Thursday afternoon warmed into the upper 70's and low 80's.  It was warm, but very comfortable because dew points dropped into the mid 40's bringing relative humidity values down into the 20% to 30% range.

Friday will be warm, but humidity should remain at a comfortable level with high moisture values remaining west of the Mississippi River.  As a warm front begins to shift east late in the day Friday and Friday night, dew points will be on the rise through Saturday morning.  Dew point temperatures will warm into low 60's by Saturday afternoon.  With highs warming into low 80's, it may feel a little uncomfortable during the day Saturday.

A few showers will be around Saturday morning with the passage of the warm front, but we may actually dry out mid to late morning and early afternoon.  Low pressure then moves in from the northwest late afternoon Saturday, with thunderstorms likely developing towards evening.

Stronger thunderstorms are possible along the warm front Friday, but this threat appears to remain a bit further north over Minnesota and the northern Plains.  By Friday night any storms that do develop may be capable of producing small hail.

With strong low pressure moving into the upper Midwest Saturday, thunderstorms will likely develop from Minnesota into Wisconsin.  A few additional storms may fire up along a cold front late Saturday evening and overnight.  Those storms could also pose a small hail threat.
