MM’s Sun Wx Forecast for July 17

For the potential of strong to severe storms this afternoon and evening.

Wx Summary

An approaching frontal system will begin kicking off scattered showers and storms across the region by this Sunday afternoon and evening. A few of those storms could be severe, with damaging winds being the main threat. Showers and storms become numerous on Monday, as that front moves into the area. Some of that rainfall could be heavy in the stronger storms. Rain chances drop by Tuesday, but we hold onto at least some rain chances through the week, with a possible uptick to 30% Wednesday night.

The main threat is damaging straight-line winds with any storm that becomes strong.

MM News

Starting on today, the blog will publish at or by 9:00 a.m. each morning. This will work better with my work schedule and allow me more time to analyze the weather before issuing a forecast. I will, of course, always publish updates when severe weather is threatening our area.

Starting in August, the MM newsletter will be published monthly, rather than weekly. The new format will be more in depth and focus heavily on the kids classes I teach and the weather of the plateau and Tennessee. There will be a new section that discusses the main weather headlines of the previous month. The new newsletter format is sure to be a hit!

Remember, subscriptions from those newsletters pay for for materials for the kids’ classes (Thank you!). Those subs are only $5 monthly or discounted to $50 per year ( Donations are also gladly accepted at PayPal ( or P.O. Box 51, Clarkrange, TN, 38553.
