Meteorologist Paul Douglas writes about Minnesota weather daily, trying to go beyond the "highs" and "lows" of the weather story to discuss current trends and some of the how's and why's of meteorology. Rarely is our weather dull - every day is a new forecast challenge. Why is the weather doing what it's doing? Is climate change a real concern, and if so, how will my family be affected? Climate is flavoring all weather now, and I'll include links to timely stories that resonate with me.

Strong storms approaching from the west
(update, 4:15 pm. Doppler radar is hinting at 1/4" hail just east of St. Cloud [small green triangle shows the location]. Remember that hail isn't considered severe unless it reaches 1" diameter, roughly quarter-size. The heaviest storms extend from Foley and St. Cloud southwest to Litchfield and Redwood Falls - the entire line is pushing east at 25-30 mph and should be exiting the St. Cloud area by 5 pm at the latest. In the Twin Cities the best chance of getting wet (or hailed on) is between 5 and 6:30 pm. A few isolated storms may still turn severe, but moisture is limited (dew points a bit too low) and most towns will only pick up thunder, lightning, pea-size hail and 60-90 minutes of rain, maybe some .50 to .75" amounts. Good news: no need to water the lawn, garden or fields this weekend!
