Welcome to the last 8 days of meteorological summer and we are
getting rewarded for making it through the hottest part of the year.
For the next week, high pressure sets up over the Midwest,
dominating the weather pattern. Temperatures will be near to below
normal through the rest of the month. Highs in the mid to upper 70s
through Thursday, then warming into the low 80s for the weekend.
Lows will be in the upper 40s to mid 50s through Wednesday morning,
then bumping up into the mid 50s to low 60s into the weekend. The
NBM is showing Tuesday morning being the coldest, with a 60-75%
chance of temperatures dropping below 50 degrees. The forecast looks
to be without rain as well to finish out August.
