ALARM DAYS: Hot and humid phase

• Some storms this morning
• This afternoon it will be hot and humid
• Heat index +95° in the next 3 days

MADISON, Wis. (WMTV) – Hopefully you enjoyed the pleasant summer weather yesterday despite the clouds. Saturday we had highs between 77 and 80 degrees Fahrenheit across the region, and we probably won’t see highs above 70 degrees for the next 7 days.

Sunday, Monday and Tuesday are warning days as they are the hottest days of the weekend and probably the most humid. The combination of these two factors will bring feels of between 35 and 40 degrees Celsius on these afternoons. This will be our first heatwave of the summer! Make sure you drink plenty of water and make sure children and pets do too.

What’s next …

A few isolated to scattered thunderstorms will move through the region this morning, bringing with them some brief showers and rumbles of thunder. No strong storms are expected and all will have passed by midday.

You may need to dry off the patio chairs, but if you’re planning on having a Father’s Day barbecue, you’ll want to get it all dry. Once the skies clear this afternoon, temperatures will rise quickly. Highs will be in the 30s, with some places reaching as high as 35 degrees.

The skies will continue to clear overnight, but temperatures will remain just above 20 degrees early Monday morning.

Looking ahead…

Things will only get warmer starting Monday: It will likely be the hottest day of the week, and temperatures will rise above 95 degrees across much of southern Wisconsin. High humidity will make temperatures feel more like 95 degrees. Sudden thunderstorms are possible in the afternoon due to the extra energy and instability of the atmosphere.

Highs will stay in the 30s on Tuesday, then drop back to 30s for the rest of the week. Humidity will remain high, increasing the chance of rain mid-week. We’ll have the best chance of storms on Wednesday and Thursday. Storm chances are lower on Friday and Saturday.
