FLASH FLOOD WATCH IN EFFECT THROUGH THE FOURTH
PERIODS OF RAIN ALONG WITH SCATTERED STORMS FOR THE REST OF THE WEEK
HEAVY RAINFALL AND LOCALIZED FLOODING POSSIBLE
WARM AND HUMID FOR THE HOLIDAY WEEKEND, WET AT TIMES
Today: Showers and thunderstorms likely. Mostly cloudy. Highs 74-80. Southwest wind 5-15 mph.
Tonight: Scattered showers and thunderstorms. Patchy fog late. Lows 64-70. West wind 10 mph or less.
Independence Day: Scattered showers and thunderstorms. Partly sunny. Warm and humid. Highs 75-81. Southwest wind 5-15 mph.
A stationary boundary just north of the Tri-Cities will provide the focus for showers and thunderstorms the next couple of days. 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 scattered thunderstorms. Any storm this time of year 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 an isolated flooding issues.
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 the weekend.
The big question remains: Will it rain on the 4th? Right now, scattered showers and thunderstorms are expected on July 4th with highs in the upper 70s to near 80°. It doesn't appear that it will rain all day, but I would prepare for periods of rain and scattered storms.
Rain chances will decrease a bit early 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 early next week. Lows in the lower to middle 60s.
Our average high is 85°, low 64°.
