First Real Heatwave Of Summer

It was a hot June. 24 out of 30 days in the month were above average. 9 days had a high of 90° or hotter. The month ended up 5° above average. It was the 6th warmest June on record.


July is going to start off even hotter. The first 8 days of the month should have highs of at least 90°. The GFS model forecast highs this afternoon appear to fall short of that but models have been running a bit too cool. Expect a high today for most areas in the lower 90s but cooler at the beaches.

Tuesday's combination of heat and humidity made it feel like nearly 100°. The good news is the air in place the next few days won't be as humid. The temperatures will just about match the heat index values for the next several days. Dew points will be more tolerable so this will be more of a "dry heat" through the weekend.

There is only a slight chance day to day for an isolated thunderstorm through Saturday. The forecast through the 4th is quiet but a shift to a more active pattern takes place late in the weekend and lasts through Thursday next week. Best chance of rain would be Monday, Wednesday and Thursday next week. The green bars on the meteogram represent rain for that period and the red bar within the green bar represents thunderstorms.

The longer range forecast keeps the heat coming well in July. Both the 6-10 and 8-14 day temperature probability forecast has us favored for above average temperatures overall from July 6th through July 14.


Here is my 7 day forecast:


Today: Mostly sunny, hot High: 91 (82 Lakefront)

Thursday: Partly to mostly sunny, hot Low: 69 High: 91 (82 Lakefront)


Friday: Mostly sunny, hot Low: 69 High: 92 (84 Lakefront)


Saturday: Mostly sunny, hot Low: 70 High: 93 (85 Lakefront)


Sunday: Partly to mostly sunny, isolated t-storm? Low: 71 High: 91 (83 Lakefront)


Monday: Partly cloudy, sct. t-storm possible Low: 72 High: 91 (84 Lakefront)


Tuesday: Partly cloudy, sct. t-storm possible Low: 72 High: 90 (82 Lakefront)
