Scattered shower chances to briefly return, with a warming trend to close out May

1 week ago | weau.com | Derrek Dalman

Clouds have overspread the area this morning, keeping temperatures milder in the upper 40s and 50s across Western Wisconsin. This is quite the change from previous mornings, where lows mostly cooled to the 30s. A cut-off upper low is parked over the region and will keep us mainly cloudy today as scattered showers become possible. Low-level dry air may prevent most of the activity from reaching us at the surface, but a small chance still exists.

It was a very active afternoon yesterday with severe weather crossing through Western Wisconsin. Storms produced very large hail in Eau Claire, while tornadoes were reported in both St. Croix and Clark counties. The NWS will assess the damage and have more information over the next couple of days. The severe weather was a result of a strong low pressure system spinning to our west and pushing a front through the area. The warm and humid air mass is now cooling and drying out.

EAU CLAIRE, Wis. (WEAU) - We’ve been enjoying a stretch of summer-like weather in Western Wisconsin as needed rain remains absent, but that will soon be changing as our next storm system moves in tomorrow. Low-level moisture, instability, and wind shear will all be increasing during the day as a warm front lifts into the region, setting the stage for an episode of severe weather during the afternoon and evening.

Scattered clouds have developed in the area this morning as temperatures are starting off mild, mostly in the 60s across Western Wisconsin. This is coming with a bit of mugginess as dew points are steady in the upper 50s and low 60s. The humid conditions will stick around today as dew points remain at their current levels, with intervals of clouds and sunshine on tap.

Our stretch of warm and dry weather continues this afternoon, but with a subtle change as dew points rise through the 50s. This will help to allow for at least scattered clouds to develop with peak heating, otherwise highs will again reach the mid-80s. When it comes to fire danger, little has changed as we range from high to extreme fire danger in the area. This means wildfires can still easily start and spready very quickly; therefore, burning is strongly discouraged.

The unseasonable warmth continues as we move through the first part of the new work week. An upper ridge covers our region, limiting any cloud cover and keeping us well above average. Meanwhile, the air remains very dry with relative humidity values under 25% for many locations. The dry air combined with the sunshine, warmth and breezy winds will continue to keep the fire danger risk in the high to extreme range across our part of the state for at least a couple more days.

We’re enjoying a beautiful start to the new work week as sunshine continues to dominate, with mainly sunny skies on tap this afternoon. This is in response to an upper-level ridge that is parked over the Upper Midwest and Great Plains. An upper low spinning over the Ohio Valley will also slide a bit farther west, making its closest approach to Wisconsin, before heading out to the east tomorrow. Highs will climb ten or so degrees above average to the mid-70s.

High pressure is located over the Upper Midwest this morning, resulting in mainly clear skies and light to calm winds. The combination has allowed for strong radiational cooling to take place, with most locations waking up to chilly temperatures in the 30s.

High pressure is located over the region this morning, resulting in clear skies and light to calm winds. In response, we are off to a chilly start with temperatures ranging from the 20s to the low 30s across Western Wisconsin. Mostly sunny skies and a light southeasterly wind on the backside of high pressure will lead to a nice warm up around our seasonable averages today as we’re expected to reach the upper 50s and low 60s.

Sun and clouds will continue to mix through the afternoon as northwest winds stay on the strong side at 15-20 mph, with gusts up to 35 mph possible. The blustery conditions will make it feel a bit colder out today, despite highs reaching the low 50s. A ridge of high pressure then builds in tonight, resulting in mainly clear skies as winds finally go light. It will be chilly as overnight lows drop into the upper 20s. The same ridge will slide over the state tomorrow before moving away to the east.
