Heat Alert! A taste of summer is coming next week. 90+ degrees!

Well, let's be honest here. We have had a FABULOUS month this May. It was mostly clear and sunny (some rain but not a lot) with  high temperatures in 70's and lows in the 50's at night. It was just great! But now reality is about to set in next week so enjoy this last week of May.

The good news is that the 90+ degree weather looks to be short lived  and then temperatures will drop back into the low 80's. In the meantime, expect a mini-heatwave between May 31 and June 4.

Here is how the National Weather Service describes it:

.Long Term...(Friday through Wednesday)
Issued at 259 AM EDT Thu May 25 2023

Models and ensembles are continuing the trend that the stagnant
central CONUS ridge will likely keep an upper low that will develop
in the southwest portion of trough, associated with a New England
and Canadian Maritimes upper low, far enough southeast to keep
showers away through Memorial Day. Previously, the GFS and its
ensemble mean had it close enough to spit some afternoon QPF over
central Indiana as early as Sunday. The upper ridge will provide dry
and seasonable weather through the weekend. The only concern would
be a potential for elevated fire danger as the continued dry weather
gradually lowers 10 hour fuel moisture levels and northeast surface
winds around the Great Lakes high will continue to reinforce MinRH
levels to around 25 percent at times during the afternoon hours
through at least Saturday. That said, winds will be marginal due to
the weak pressure gradients both at the surface and top of the
mixing height.

For Holiday weekend outdoor activity planning, even in a worst case
scenario, believe any shower activity will be brief, isolated,
diurnal in nature and not until Monday afternoon at the earliest.
Afternoon temperatures in the 70s to lower 80s along with the low
humidity levels will make it feel comfortable for humans and
pets alike.

Isolated diurnal convection would seemingly be more plausible toward
the middle of next week, when a broad ridge builds over the area and
dew points rise as winds take on a southerly component. Even then,
shear will be likely for any kind of organized convection. Being
firmly entrenched under the ridge, 90+ degrees look a very real
possibility by Tuesday or Wednesday.
