I’ll have your weekend forecast details in a bit. First, here’s an important update on our current heat wave.

High temperatures will reach the upper 90s across much of Minnesota and parts of western Wisconsin this Thursday afternoon. A few spots could hit or exceed 100 degrees. The heat index will reach or exceed 100 degrees in many areas.

Here’s the National Weather Service definition of heat index and why it’s important:

An excessive heat warning began at 11 a.m. Thursday in the Twin Cities metro area and continues to 8 p.m. this evening. A heat advisory (shaded orange) continues until 8 p.m. in much of Minnesota plus several counties in western Wisconsin:

Here are details of the excessive heat warning:

, and you can see updated weather info on the MPR News 

Our Twin Cities temperature was 90 degrees at 11 a.m. Thursday, and we’re expected to top out in the upper 90s this afternoon. This is our eighth consecutive day with a high of 90 degrees or warmer in the Twin Cities:

We’ll probably top 90 again on Friday, extending our streak to nine days. 

Saturday highs will retreat to the 80s in many areas, with some 70s in far northern Minnesota and a few 90s in the southwest:

Saturday afternoon dew points will be in the comfortable 40s in many locations:

Sunday high temperatures return to the 90s in most spots, with 80s in far northern Minnesota:

It’ll feel a bit more humid by Sunday afternoon, as dew points creep into the 50s:

At this point, it looks like Saturday and Sunday will be rain-free in most locations.
