In this update: (1) Storms Late Tonight. (2) Eclipse Cloud Cover guesses.
(1) Storms Late Tonight.
ETA midnight tonight, ETD 4 AM. Timing may change.
Heavy rain, lightning likely.
Severe (tornado, damaging straight line winds, hail) unlikely. We’re not outlooked by SPC. Those outlooks apply west of us.
About eclipse cloud cover and sirens …
Clouds are in blue below. This is the HRRR model. It’s probably going to change. Probably change A LOT. Also, I have no idea what track record the HRRR has with cloud cover success 48 hours out. So take with grain of salt.
Back into the 60s today! Sun, high of 63°.
First Saturday of the month. Tornado siren tests are today. Davidson Co at noon. Williamson at 1:00 pm.
Good idea to cover up plants tonight, a Frost Advisory will be in effect from 4am thru 9am Saturday morning.
Lows are expected to get down into the low 30s, thankfully temps will quickly recover Saturday afternoon and make it into the low 60s.
Temperatures will dip into the mid 30s tonight, which may bring some frost to the area. A few backyards may dip below the freezing mark.
Friday high temps will reach the upper 50s, but Friday night will have our coldest temperatures of the forecast, with temps in the low 30s. A few places may get down into the upper 20s. Good idea to cover up any loved plants.
Pockets of on/off rain continue to move thru the area, coverage will decrease as we head into tonight. Still can’t rule out some more brief graupel/small hail aka Sonic ice in some of the showers.
Temps aloft below freezing. Graupel/frozen precip like Sonic Ice may fall out of these showers this afternoon.
The cold front has passed through, bringing in cooler air and signaling the end of our severe weather threat.
High temperatures Wednesday – Friday will be about 20° cooler than we experienced today. Gross.
Our probabilities from the SPC remain unchanged for now. Within 25 miles of you, there is a 30% chance of damaging straight-line winds, a 30% chance of large hail and a 10% chance of a tornado, which could be strong (EF2+).
