Tornado Watch from 10pm Mon-6am Tues
Tornado Watch in effect now until 6 am for our northeastern Iowa counties, into southwest Wisconsin.
I can’t believe I’m typing this, but this is just how powerful this storm system is, guys. Strong storms can’t be ruled out over the rest of the area, but by far, the severe storms – the ones that may be capable of producing tornadoes – should be confined to the tornado watch area.
Why? Add a “bombing” (met. talk for rapidly deepening storm system) low, strong moisture transport, and a ton of strong spin in the atmosphere, and you have the ingredients for wonky end-of-October severe weather.
High Wind Warning Tuesday 7 am to Wednesday 7 pm
4:00pm update: High Wind Warning has been issued for our entire viewing area from 7 am Tuesday – 7 pm Wednesday. Winds will increase tonight and will be sustained 25-40mph+, with gusts to 55-60mph+. That will be enough to make getting around difficult and could cause some damage to trees, powerlines, anything loose outside.
We’ve been telling you for a few days now about a large, intense storm system that is going to be pushing through the Upper Midwest in the next day or so, producing some rain and nasty winds for our area, and that still certainly looks to be the case. However, there are other parts of the region that will potentially have a much worse situation than we will as
Strong winds and light snow will possibly create blizzard conditions for portions of North Dakota and northern Minnesota. This storm system will push through the region between tonight and Wednesday.
snow…yes snow will likely enter the picture and blizzard conditions will be a real possibility. The latest forecast data suggests that northern North Dakota and far northern Minnesota will be on the north side of the storm system and will experience a change from rain to snow Tuesday night into Wednesday morning with two to four inches of accumulation during the day Wednesday into Wednesday evening before the storm system moves away to the northeast, putting an end to the precipitation from this event. Of course, when you add in the 45 to 55 mile per hour gusts that will accompany this snow on Wednesday, there will likely be some nasty blowing snow and blizzard conditions. If you have travel plans to that portion of the region, make sure to keep up to date on the forecast picture in the next day or two and possibly push your travel plans to Thursday when the weather will be much quieter.
Our local weather will be a bit wet today with a few scattered showers possible during the day, especially late in the afternoon. There will be more widespread thundershowers in the area this evening and overnight tonight with an inch or more of rainfall possible as that storm system and its associated cold front push through the Upper Mississippi Valley. The winds we’ve been talking about will pick up quite a bit overnight and very early tomorrow morning, gusting to 40 miles per hour initially with gusts to 50 miles per hour in the afternoon while the rain gradually tapers off. Wednesdya will feature a few sparse light rain showers with strong southwest winds that will reach 50 ot even 60 miles per hour at times while high temperatures will be only in the middle 40s. A High Wind Watch is in effect from tomorrow morning through Wednesday evening because of the dangers to property and high profile vehicles from those intense winds.
