Colder Weather is Back!

We got to the mid-60s on Thursday, but that’s as warm as it will be for quite some time. Colder weather is here to stay!

Temperatures are cool this morning with a gusty north wind. It stays breezy and chilly all day; daytime highs only rise to the mid-40s.

Weekend Rain Potential: The weekend forecast remains on track: dry and cool Saturday, wetter and still cool on Sunday. Saturday is clearly the best day to be out and about this weekend; it starts out cold in the upper 20s, but we see a warm-up into the lower 50s by mid-afternoon. Expect a sunny sky early on with a gradual thickening of high and mid-level clouds later in the day.

Rain moves in Saturday night into Sunday morning and sticks with us for most of the day: on-and-off showers from daylight to dark. Temperatures rise into the low-50s in the afternoon with a south breeze up to 15 miles per hour. We don’t see any real potential for thunderstorms here, but some of the downpours could briefly get heavy. In all, rainfall totals should add up to around 0.25” to 0.50” on average with some isolated spots getting over one inch.

Turning Colder Quickly: The persistent Sunday rain slacks off late in the evening, but enough moisture will linger behind for some light showers and drizzle overnight. Colder air moving in from the northwest means some of that will change over to snow flurries and snow showers through Monday morning.

We do not see much chance of significant snowfall with the change-over; however a dusting to a half-inch of snow is a possibility in the higher terrain of the Cumberland Plateau, Sand, Lookout, and Brindlee Mountains. Any accumulation would occur on the grass; roads should be fine.

The big story will be the cold air for next week! It comes in two waves with the first arriving Monday. Expect highs in the 30s and 40s all week long; lows will plunge to the 10s and 20s early Tuesday morning and again on Thursday and Friday.

Midweek Precipitation: A storm system developing toward the middle of next week bears watching. If it can phase with the northern branch of the jet, we could have something wintry on our hands. The odds are in favor of a cold rain right now, but we will have to keep a close eye on how that evolves on Wednesday and Thursday.
