As weather systems evolve, forecasters chase the changes. That’s the case today, as earlier expectations of a less-than-noteworthy batch of moisture has evolved, with increasing confidence in forecasts of flood potential. And now, the chance of storms producing excessive rainfall is raising caution against flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. The National Weather Service says that flooding may also occur in poor drainage and urban areas.
Concerns center around thunderstorms that are forecast to concentrate along a front that initially lifts northward as a warm front this evening, and then returns southward as a cold front Saturday night. With ample moisture available to fuel potentially-flooding lines of thunderstorms, the National Weather Service has expanded a flood watch to include Sheboygan County along with all surrounding counties except Ozaukee through Saturday evening.
Although the threat of severe weather is only slight – a level 2 out of 5 at maximum – it’s not out of the question that damaging winds, small hail and significant rains could occur both tonight…and on Saturday, when there’s an additional risk of possible tornadoes. The National Weather Service did acknowledge that storms may weaken as they approach Lake Michigan, but regardless the most likely time frame for any form of severe weather will on Saturday be between 4 and 11 p.m.
