Severe Storm Watch Northern/Central Minnesota until 10 PM
June 20, 2014 — 3:34pm
Here We Go Again. Odds favor most of the T-storms passing north of MSP, with the best chance north of Alexandria and Little Falls, but a few stray T-storms can't be ruled as far south as the metro area. The blue-shaded area shows a Severe Storm Watch posted until 10 PM. NWS Doppler radar at 3:33 PM. Details from NOAA SPC:

Your eclipse viewing Monday may be hampered by a few clouds across the region, but the chances of rain here in the Twin Cities should mainly hold off until the evening hours. After we get past Monday, however, the rest of the work week looks nice weatherwise! Click for more details. - D.J. Kayser
Latest weather models are a tad more optimistic about the weather on Monday. The best chance of seeing the (so-called) eclipse will come over central & northern Minnesota. Clouds and showers may overspread southern counties by afternoon. Fingers crossed. Check the blog for more details. -Todd Nelson
Friday was delightful (what a shock - more rain) but today will be a step in the right direction. Fog and low stratus should burn off, with enough PM sun for highs near 80F. Sunday looks warmer with an isolated thundershower. I'm paranoid about Monday's eclipse - NOAA and ECMWF models continue to bring clouds and showers into the area Monday. If we do see the eclipse it'll be a minor meteorological miracle.
The month is a little more than half over and we've already picked up over 4" of rain in the metro (airport) but some communities have seen closer to 7-10" of rain in August. It looks and feels more like June out there. Shocking weather news: more T-storms may bubble up later today, but the weekend looks pretty good, especially Sunday. Keep expectations low for Monday's eclipse (not sure the weather will fully cooperate here) but skies clear and temperatures and humidity levels come down for the start of the Minnesota State Fair next Thursday. Man, the summer flew by...
I was concerned about flooding from yesterday's slow-moving storm, and I talked about it in print and on 'CCO Radio. What caught me off-guard, as well as nearly every other meteorologist, was the ferocity of the T-storms that pushed northward late in the day, spinning up a series of tornadoes and some extreme 2-4" rains. Flooding will remain a problem today, especially central Minnesota, but a pretty nice weekend is shaping up. We're due...
