First Alert Friday before a drier Mother’s Day
Meteorologist Ben Cathey tracks several lines of intense thunderstorms Friday. Saturday is dreary, Sunday is pleasant.
KNOXVILLE, Tenn. (WVLT) - There are numerous rounds of pre-dawn rain and storms, so plan to pack the rain jacket. Everyone gets rain, including at least two lines of strong thunderstorms Friday. That’s a WVLT First Alert Weather Day.
Dreary and cool showers linger with us Saturday but Mother’s Day starts a substantial warming trend.

WHAT TO EXPECT
Winds created damage just west of our area, with power outages in White County.
There’s also a quick window of less severe rain after midnight, and into very early Friday. This is NOT the WVLT First Alert. The lows will be very warm, with almost everyone waking up to the 60s.
You will really want to pack the rain gear in the van or truck Friday, but we will not have immediate rain as most head out the door. The WVLT First Alert starts at 10:00 a.m. Friday, continuing to 4:00 p.m.
Nothing has changed here except the overall coverage of rain. Rain is now a slam dunk. Reminder: there are two distinct lines of storm. There will even be sunshine in between.
The first line is 10:00 a.m. - 12:30 p.m. give or take a few minutes. These move from west to east. Damaging winds, ponding water, and even some rarer hail are possible. Just plan on an inconvenient lunch rush Friday. After that rain, it’s a break for an hour or two. Around 2:00 p.m. storms re-develop. These storms could also be severe. The big threat is *not* tornadoes but a brief twister cannot be ruled out. Lightning, rain, and wind are the bigger deals here.
Note that storms are still around after 4:00 p.m. There could be several more rounds of rain. Then we have some mountain fog by the evening. Temps will have a huge variation, but the brief high could be 76 degrees.
Saturday looks colder than ever before - with light rain moving northwest to southeast. The temps are in the lower 60s for much of the day. Technically, there is a high of 66 degrees.
Happy Mother’s Day! There’s a limited chance of showers, mostly early Sunday, and mostly in the Foothills or Smoky Mountains. We’re partially cloud-covered, with decent windows of sunshine. This also really cranks up the warming trend.
