Last year MSP Airport recorded the fist freezing temp on October 17th when we hit 31 degrees. Looking ahead on the maps, milder air returning will probably keep the MSP area frost-free through at least the end of September

Canadian high pressure

A Canadian high pressure cell brings us the coldest morning since May 18th Wednesday. Warmer breezes return around the back side of the high by Thursday. The next wave of showers rolls in later Thursday.

Summer returns by Monday

Friday's low pressure system looks more 'progressive' than it did earlier in the week. That means the weekend is looking brighter. High in the 70s this weekend give way to warmer south breezes and highs in the 80s Monday and Tuesday. The upper air ridge builds over the Midwest next Monday.

NWS 'Integrated Warning Team' team meets in Bloomington

I was honored to be asked to present and discuss challenges and opportunities for broadcast media during severe weather coverage at the NWS Integrated Warning Team meetings this week in Bloomington.

The IWT is a group of meteorologists, emergency services managers and others who are responsible for communicating and acting on severe weather across the Upper Midwest. We discussed how to streamline communication and weather warning information for the public, school administrators and anyone else who uses severe weather information.

The IWT meetings run through Wednesday.
