MM’s Sun Wx Forecast for July 3

Wx Summary

A stationary frontal bounday will produce scattered showers and thunderstorms for today, especially in the afternoon and evening. Those showers and storms should die down by midnight. The frontal boundary is expected to slip just south of our area for the Fourth of July, giving us lower rain chances. Things are looking good for fireworks Monday night! As we get into Tuesday, the frontal boundary drifts back to the north, beginning another pattern of scattered mainly afternoon and evening showers and storms through at least Thursday.

This Week’s Hazards

Any storm could be locally strong to even severe, with damaging winds being the main threat.

Always be mindful of the deadly cloud-to-ground lightning with storms.

MM’s Wx Vlog

Weather Forecast

Sunday: Partly to mostly cloudy, with scattered showers and thunderstorms, especially in the afternoon and evening. Rain chances should taper off by midnight.

Independence Day: Partly cloudy, with a chance for mainly afternoon showers and storms. Skies should be partly cloudy for fireworks.

Tuesday – Thursday: Partly cloudy, with scattered showers and storms, esp in the afternoon.

MM’s Severe Wx Concerns 

Any storm that develops this weekend could be locally intense, with deadly lightning, gusty winds, and heavy rainfall. Keep an eye to the sky and an eye on the radar if you have outdoor plans. If you’re close enough to hear thunder, you’re close enough to be struck by lightning.

Drought Outlook

Drought info can be found at my link at That link also allows you to compare this week’s map with last week’s. The maps update each Thursday.

Drought conditions continue to worsen across the state and here on the plateau.

On This Day

1987 – Lightning struck and killed three men playing golf on a course near Kingsport, Tennessee. The three men had sought shelter from the rain under a tall tree on a small hill.

1863 – Battle of Gettysburg, largest battle ever fought on the American continent, ends in a major victory for the Union during the US Civil War.


Hurricane Forecast

The only system to mention now is “Colin”. That tropical system quickly developed yesterday along the Carolina coastline and is now just an area of weak low pressure. Nevertheless, that system will continue to produce showers and storms for that region today.
