Hello Heat Index!

One year ago today, Minneapolis/St. Paul hit 103° which turned out to be the hottest day of 2011.  The hottest day so far this year was 93° on May 18.  This upcoming weekend might be the hottest yet and certainly one of the more humid weekends we have had so far.  Our mini heatwave starts Friday with the hottest day being Saturday as highs top 90° and dewpoints near 70°.  Generally, when the dewpoint gets above 60° it feels sticky and uncomfortable outside.  The body can’t readily cool itself thanks to the evaporation process being slowed by the increased moisture in the air.  So if you plan on heading up to Crosby Saturday for the Cuyuna Lakes Mountain Bike Festival stay hydrated and don’t forget the sunscreen.  The sun is as strong now as it will ever get during the year.

Saturday's Heat Index

Bring on the Heat

I, for one, love the heat and humidity.  But for those that can do without the sticky factor just know that it can be worse.  For example, you could live in Dubai where, depending on the wind, the heat index could reach 122°!  Read more about the crazy heat along the Persian Gulf here.

Severe No Show

June can be a volatile month, especially in Minnesota.  Good news for us (bad news for the storm chasers) is that the major severe weather outbreaks have steered clear of MN.  The biggest severe outbreak the nation had this year was on March 2 with 687 total storm reports stretching from Indiana to Mississippi.  Minnesota’s next threat of severe weather comes Sunday when a cold front rips through the weekend heat.

Dual-Pol Radar

A new weather technology is coming to the Twin Cities in September.  Dual-Polarization Radar is a new type of Doppler Radar that will help meteorologist better determine a dangerous, potentially life-threatening storm.  Conventional radars send out horizontal radar beams that determine where precipitation is falling, the intensity and movement.  The new Dual-Pol radars send out both horizontal AND vertical beams.  For the first time, we can get information about the size and shape of the storm objects like tornado debris, hail and flooding.  This technology is so good it can even detect the difference between wet and dry snowflakes!
