A severe thunderstorm warning is issued for storms that reach certain criteria.
If clouds and rain hang around for much of the day, the severe threat will be lower.
Again, an outbreak of severe thunderstorms is possible for the Southern Plains this afternoon. We will discuss further about this at breakfast, but this area appears to be most favorable for discrete supercell as opposed to central Kansas where an mesoscale convective systemmay develop later today.
In between the showers, this afternoon may bring a brief stretch of sun, but the heat will just fuel the thunderstorms, Kern said. Yes we could see 1 or 2 severe warned storms develop, but this is not a widespread severe weather setup.
The storms, however, will be capable of producing strong winds of up to 70 miles per hour, very large hail of up to 2.5 inches in diameter, and torrential rains of up to 2 inches in some spots, according to the National Weather Service. It should be stressed that this timing is based on our best estimate of thunderstorm development and may change with little notice. The air, out ahead of this cold front, will be fairly warm and very humid. The National Weather Service office in La Crosse received numerous reports of winds topping 50 miles per hour, and trees and power lines are down in Green and Lafayette counties.
Heavy rainfall may also bring some streams, creeks and rivers back to flood early this weekend. All modes of severe weather are possible. The greatest threat will be across our western counties approaching the I-35 corridor this afternoon and evening. Isolated tornadoes can't be ruled out.
The Wisconsin tornado was part of a huge swath of the Plains and Upper Midwest threatened with severe weather.
The storms hit late in the afternoon Tuesday and into the evening, leveling the Prairie Lake Estate Mobile Park near Chetek, Wisconsin. Additionally, the Storm Prediction Center has a Marginal Risk of severe weather posted for all of the WAFB viewing area.
A storm capable of producing hail an inch in size or larger. There will be occasional lulls in activity, but don't let that fool you into thinking we're done with rainfall completely. Storms may begin to loose some of their punch as we get closer to midnight, however individual storms will merge into clusters and/or a line of storms and damaging wind gusts will still be possible.
However, there is the added threat of tornadoes today, especially areas west of Madison.
Is rain guaranteed Thursday? .
