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.

Yes, La Nina correlates with colder, wetter (snowier) weather for northern tier states, and that could mean a better chance of happy snowmobilers and cross country skiers this winter. Average snow would be nice, about 54", give or take. Odds favor a tougher winter than last year, but I wouldn't assume worst-case (polar vortex) scenarios just yet...
It actually feels like October out there. Soak up the chill because a mild bias continues as far ahead as we can see, certainly into the first week or two of November. Snow? I don't see it - in fact many suburbs within 20 miles of the downtowns will remain frost-free for another week or two. As has been the trend in recent years we're getting another Super-Sized Autumn
Tuesday was extraordinary (nice not to be tracking red blobs on Doppler radar). Today looks a bit cooler, and you may even need a sweatshirt or light jacket by Thursday morning. If you can avoid a frost Friday morning odds are your yard will remain frost-free into next week, maybe Halloween at the rate we're going.
My dog is really looking forward to an end to the thunderstorm season. He was not happy last night, with a few waves of heavy T-storms, hail and high water (Doppler radar suggests up to 2" of rain fell over parts of the south metro). Some October. We dry out today, you may even require a light jacket later this week as we limp into autumn. Oh, today's blog has me thinking about buying an emergency generator to keep the lights on.
Sunday was a beautiful day across most of Minnesota - it almost felt like spring out there, complete with a few nighttime T-storms that left my dog very unhappy. Showers and T-showers linger today, but we dry out tomorrow and cool off later in the week. Nothing I'd call a cold front. Folks in Oklahoma and Texas may be praying for some of that Canadian air - 100F later today. On October 17. Welcome to the new normal.
