THE HEAT IS ON!

We managed to top out at 95/96 degrees this weekend in the city–highest readings of the year so far.

Portions of central Ohio are under an air quality alert again Monday during the daylight hours, including Franklin, Delaware, Licking and Fairfield counties. The combination of sunlight, strong heating and little wind will allow concentrations of ozone to increase to unhealthy levels for sensitive groups.

As high pressure drifts east, light northerly breezes will diminish, and then turn southerly early in the week bringing an increase in humidity to go along with the heat. This will translate into a few late day pop-up storms Monday, primarily over the western counties, though isolated storms could develop in the Columbus area toward evening.

An upper-level low will start to push on the resilient high-pressure ridge by midweek, coupled with more moisture streaming north in a southwesterly flow. Expect scattered storms on Tuesday, then spotty coverage of storms during the latter part of the day, with plenty of heat and humidity.

A cold front will arrive on Friday, with an opportunity for more widespread rainfall, followed by a break in the heat and humidity next weekend.
