MADISON (WKOW) – Not to say we won’t have a couple warm days mixed in, but the overall pattern shows below average temps through the official start of summer.

Average highs this time are in the mid to upper 70s with average lows in the mid 50s.

SET UP
The jet stream, which divides air masses, is set to push south of Wisconsin, allowing us to tap into cooler Canadian air as a “trough” develops.

Geopotential height snapshot by Thursday: blue shows sinking air (cooler) reds show rising air (warmer)

Because of this pattern shift, the Climate Prediction Center has issued a 50-70% chance of below average temps through June 23rd .

FORECAST
Expect plenty of sunshine today with high pressure taking control, but a breezy NW wind will give the air some added bite. Highs will be in the low to mid 70s, a few degrees below average for this time of year.

Tuesday looks mostly problem-free with highs in the mid 70s. Expect fading sunshine ahead of low pressure developing over the Northern Plains, possibly leading to a stray afternoon shower or t-shower. A slightly better chance will come Tuesday night, with a much better opportunity on Wednesday with low pressure overhead. The clouds and showers will make for an unseasonably cool day; highs only in the mid 60s.

We stay cool, but drier, on Thursday with highs in the upper 60s.
