It's hard to believe that we're about halfway through June, and so far, things have been mostly quiet. This pattern will continue, with mostly dry conditions expected through the forecast period. This is the last weekend of spring, and right on cue we're watching increasing signals for heat by the end of the week and official start of summer. Let's dive in!
Expect plenty of sun and relatively comfortable temperatures. All week, high pressure is expected to dominate. However, for the first half of the week, the upper level pattern is such that temperatures should be held in check by a more amplified pattern that puts the bulk of the heat over the Midwest. Some locations in the upper Midwest may be approaching the upper 90s during this part of the week!
The latter half of the workweek looks fine as well, but we will see slightly higher chances of some stray showers. Despite the increasing precipitation chances, both days look partly to mostly sunny. Temperatures and humidity will be on the rise, and we could be seeing inland temperatures in the upper 80s to low 90s by Friday, setting the stage for what may be our first heat wave.
To recap, a heat wave is defined as three consecutive days of 90 or higher temperatures. We may get there for the first time this year on Friday-Sunday, but I think the odds right now are 50/50.
Things depend heavily on the placement and progression of a cold front. Saturday and Sunday look hot and humid, but there could be some popup showers and storms that would keep temperatures down. Currently, it looks like the front may wait for later Sunday or early Monday, which would increase the chances of heat building over the region, but we'll keep watching to better fine tune the timing of the front.
Monday: Mostly sunny. Highs in the low to mid 70s.
Tuesday: Mostly sunny. Highs in the upper 70s to low 80s.
Wednesday: Mostly sunny. Highs in the low to mid 80s inland and upper 70s to low 80s at the shoreline.
Thursday: Mostly sunny with increasing humidity. Highs in the mid 80s inland and upper 70s to low 80s at the shoreline.
Friday: Mostly sunny. Hot and humid inland. Highs in the upper 80s to low 90s inland with highs in the low to mid 80s at the shoreline. Chance of showers 20%.
Saturday: Partly cloudy. Hot and humid. Highs in the upper 80s to low 90s inland with highs in the mid to upper 80s at the shoreline. Chance of showers 20%.
Sunday: Partly cloudy with a chance of showers and thunderstorms late. Hot and humid. Highs in the upper 80s to low 90s inland with highs in the mid to upper 80s at the shoreline. Chance of rain 50%.
