First frost of the season tonight? Temperatures warming into next week.

The National Weather Service offices in Nashville, Memphis, Huntsville, and adjacent areas have made the very wise decision of placing a large part of the Tennessee Valley area in a Frost Advisory for tonight into tomorrow morning, valid in our area until 7:00am Saturday. Morning lows by daybreak Saturday look to drop well into the 30s, and it's very possibly if not likely that we will be dealing with our first widespread light frost of the season. This means tender vegetation has to be protected overnight.

Clear skies will continue tonight after a sunny bit cool Friday. That will allow the radiational cooling that will let temperatures drop into the 30s overnight, but even before then, we will be chilly as early as the evening. If you're headed out to dinner or to the high school football games this evening, be sure to bring a jacket. Temperatures will be down into the upper 40s as early as kickoff time for the high school games around 7:00pm, and only dropping from there as we head through the evening.

If you have plans outdoors this weekend though, it's going to be great! After the cold start Saturday morning, temperatures rebound quickly with afternoon highs in the mid to upper 60s under mostly sunny skies. Winds become a bit more westerly as we head into late Saturday night and Sunday morning, and because of that, temperatures won't be quite as chilly. Overnight lows look to stay in the mid 40s, and then we rebound into the low to mid 70s by afternoon with a mix of sun and clouds.

The good news continues as we head into the new work week. We will have a weak front or two that may bring a stray shower around Monday night or Tuesday, but otherwise, it looks like we stay warm for the week with a mix of sun and clouds each day and highs getting into the mid 70s. Some of us may even have upper 70s for a day or two. Overnight lows moderate as well, getting back into the mid 50s as we head into the new week.
