LATEST FORECAST DISCUSSION
Meteorologist: Darren Maier
The Memorial Day holiday weekend so far has brought some nice weather to much of Western Wisconsin, with the exception of northern areas where it has been cooler and occasionally wet. We will all be going through changes in the next 24 hours though, as an upper trough continues to slide further south over the state. This means as we head into Memorial Day itself, we will be cooling down and also be watching for scattered rainfall.
Scattered showers and thunderstorms are moving through Northwest Wisconsin this evening, some with heavy downpours and small hail. These are being energized by the heating of the day and will likely start to dissipate as we move into tonight. Most of these can be expected north of I-94. The overnight will be partly to mostly cloudy with just the chance of a shower and lows near 50.
Memorial Day will bring some change as cooler air arrives along with extra clouds. The holiday will be mostly cloudy with highs not getting much above 60. The good news if you do have outdoor plans is that it shouldn't be all that wet. The morning will be mostly dry, followed by scattered afternoon showers but chances will again be greatest in northern areas. It will also be breezy, so if you plan on going to the area parades, you may want that jacket. The upper trough will continue to be over the area at night and through Tuesday, though beginning to move to our east. Still, it will remain mostly cloudy, and with the core of the coolest air over the state, we look to remain in the 50's for most areas. A stray shower will be possible but much of the time looks dry.
Conditions will be improving moving forward into the middle part of the week and May will finish up with some nicer weather on Wednesday. As the upper trough continues to move away, surface high pressure will be taking hold, bringing drier air back into the region. Wednesday will be mostly sunny and warmer as temperatures climb back to around 70.
Later this week the forecast will revolve around the placement of a front stretched out to our south. Some forecast models have this near or over our area while others have it far enough south to keep us dry. At this time I'm favoring the drier solution so Thursday will come with a mix of sun and clouds with highs returning to the more seasonable 70's. We should continue to be around average into Friday with a similar day.. sunshine and clouds and highs in the 70's. Right now the next best chance of showers and storms may arrive by the start of next weekend. Saturday currently looks mostly cloudy with the chance for a few showers and storms while Sunday dries out and cools down just a bit.. highs both days will be closer to 70.
