It appears summer has returned to central and northern Wisconsin with temperatures climbing well above normal. The warm pattern will stick around through the end of the week but it will be a lot more unsettled starting Wednesday. First of all Monday night looks mild and quiet with lows around 59. Patchy fog is possible but it shouldn’t be the thick widespread type like last night. The wind will be from the south-southeast around 5 mph. Tuesday will feature a mix of sun and clouds along with balmy highs mostly in the low 80s. It will be somewhat muggy with dew points in the low to mid 60s. Winds will remain from the south-southeast around 7-15 mph.
A front will approach from the west Wednesday bringing thicker clouds with it. Also we have a 50% chance of a few showers and thunderstorms, with the highest odds late in the day and into Wednesday night. It will still be very mild with lows around 61 and highs around the upper 70s. There is a 40% chance of scattered showers or thunderstorms again Thursday but the timing and placement is still rather uncertain. Temperatures won’t change much with lows in the low 60s and highs around 76 degrees.
The next low pressure system will track up through the Northern Plains Friday. This will increase the southerly winds in our area. As such it will reinforce the humidity and bring the risk of some spotty showers and thunderstorms. The showers and thunderstorms could be more widespread Friday night and Saturday as the main part of that Plains system arrives. Some locally heavy rain is possible given the very moist air that will be in place. Again is looks breezy as well. High temperatures will be in the mid 70s Friday and lower 70s Saturday.
Cooler and less humid air will filter into our region by Sunday as the front clears Wisconsin. We expect partly sunny skies and highs around the mid 60s. Next Monday is shaping up pleasant with lots of sunshine and highs around the upper 60s.
Have a good evening! Meteorologist Tony Schumacher, 2:20 p.m., 16-September 2019
