Weather Summary:

A stationary boundary just north of the Tri-Cities will provide the focus for showers and thunderstorms this holiday weekend. As weather disturbances move along this boundary, clusters of showers and storms will be guided from west to east across the Tennessee Valley into the southern Appalachians.

This will result in periods of rain along with a few thunderstorms. Any storm in this type of atmosphere can produce downpours and gusty winds. The severe weather threat, as in damaging winds and hail, remains low.

Rainfall totals through the 4th of July may end up around 1 to 2 inches (locally heavier possible). It will not be raining the entire time, but have the rain gear handy over the next few days. A Flash Flood Watch is in effect for most of the region through Saturday. Pockets of heavy showers may lead to isolated flooding issues, especially in low lying areas near bodies of water.

As the main disturbance lifts northeast of the area, we can expect more numerous showers and storms at times on Sunday.  Again, downpours and gusty winds are possible in this kind of environment.  Scattered showers are still possible on Monday as the disturbance is slow to lift.

Aside from that, temperatures won't be nearly as hot as we saw during a large portion of June. Highs will be in the 70s to lower 80s through Monday.

Rain chances will decrease a bit starting on Tuesday of next week as the jet stream lifts north of the region. Temperatures, as a result, will return to near average... in the low to mid 80s.

Recap: Highs in the middle 70s to lower 80s through Sunday. Highs in the lower to middle 80s Monday through Thursday. Lows in the 60s.

Our average high is 85°, low 64°.
