MM’s Wed Wx Forecast for June 29

Wx Summary

Humidity begins to increase a bit today, which could lead to a shower or storm on the plateau by this evening. Humidity increases a bit more tomorrow, which could lead to a few more showers and storms on the plateau. By Friday, a slow moving cold front begins sagging into the area, which is expected to lead to scattered showers and thunderstorms through the holiday weekend. The weekend is not looking like a washout, but you need to keep that storm chance in mind if you have outdoor plans. Any storm that develops could be intense (like any summer storm)

This Week’s Hazards

Any storm that develops could be locally strong, with deadly lightning, heavy rainfall, and gusty winds.
