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!
