Severe weather, tornado watch in effect across the area

Posted:

Sunday:  Variably cloudy, breezy, warm and humid.  Isolated showers in the afternoon, then scattered severe thunderstorms in the evening.   High:  75   Wind: South 10-20

Monday:  Occasional showers through midday, windy and cooler.  Clearing in the evening.  High: 53   Wind: NW 15-25 gusting to 35

While the unseasonably warm and somewhat humid conditions sweeping into Wisconsin Sunday probably felt nice to a lot of folks, it could lead to a significant severe weather outbreak across the region Sunday evening.  A strong low pressure system tracking northeast toward Lake Superior Sunday evening will push a cold front into the warm and humid air.  This should allow for explosive thunderstorm development.  Due to strong and turning winds in the atmosphere conditions are conducive for several tornadoes in our area, some of which could be strong and long tracked.  In addition damaging thunderstorm winds over 70 mph and hail to golfball or baseball size are possible as well.  These storms will move very fast, probably 50 miles an hour to the east-northeast thanks to the strong steering winds in the atmosphere.   Obviously this is a potentially very dangerous situation and everyone should monitor the latest conditions very carefully.  By the way a FLOOD WATCH remain in effect through late Sunday night for Lincoln, Langlade, Marathon, Shawano, Menominee, Wood, Portage, Waupaca, and Waushara Counties.

We expect the thunderstorms to taper to scattered showers late Sunday night as the low pressure system pushes up into Canada.  They could linger into Monday before ending by midday or so.  It will be colder and rather windy as well with temperatures staying in the lower to mid 50s.  Tuesday looks pretty nice with lots of sun with a few clouds late.  Highs could rebound to the low 60s as south winds return ahead of the next cold front.  That front will settle in here Tuesday night and Wednesday bringing a chance of showers.  A storm may develop in the middle of the county Thursday and move across our region Friday keeping us wet and chilly.  It could also be rather breezy.  Highs may drop back to the 40s Friday and Saturday.

So again, the main timeframe of possible dangerous storms will be from about 4 p.m. to 11 p.m. Sunday across the TV-9 viewing area.  Please watch TV-9 as Justin and Tony will keep you posted.  You can also follow the radar and warning information, right here on waow.com.
