Strong Storms Rumbling Through Metro (wind gusts to 50 - small hail and urban flooding risk)
September 19, 2013 — 11:36am
Much-Needed Lawn Watering. NWS Doppler radar at 11:04 AM shows a line of strong storms pushing across the metro, whipping up 50 mph winds and small pea-size hail. The most severe storms are over the far north metro, NWS Doppler estimating 2.75" diameter hail east of Cambridge. The severe threat will shift into southeastern Minnesota and much of Wisconsin into the afternoon hours. Remember that a Severe Storm Watch is in effect until 4 PM, including the metro, but the severe threat for the immediate Twin Cities should ease after noon or 1 pm as the most unstable conditions shift south and east of the metro.

I predict precious few complaints about the weather today with pleasant temperatures and low humidity; summer heat in retreat for now. A few more waves of heat return next week - although probably not as torrid as last week. Most of us probably won't see rain until Monday. Mosquitoes? No promises there...
Only in Minnesota can you be knee-deep in flood waters with dust blowing in your face. Weather has always been extreme at this latitude, but there's growing evidence the swings are becoming even bigger. Which brings up the challenge (and opportunity) of managing water: too much water, or not enough water. More showers sprout today but generally dry weather is likely Friday into Sunday as temperatures moderate. The first week of August may feel more like mid-July.
Another free lawn-watering today (showers and T-storms, probably not severe) gives way to a clearing trend and a drop in humidity Thursday. The upcoming weekend looks lake-friendly, warm, but not obnoxiously so. Next week may see a few more 90s with a couple days of dew points in the oh-zone.
Monday was a fine summer day; a touch of heat and humidity, but not as swamp-like as late last week. We may brush 90F today before cooling off later this week - a good chance of heavy showers and T-storms Wednesday and Thursday. Long-range models hint at another hot front as early as next week.
