Rain, Snow, Wind, COLD: Tomorrow (meh) & Sunday (hmmm)

Latest Official Hourly Observation:

Tonight  – Chilly Rain  Midnight Temp 41


Rain is starting to move into Middle TN tonight. It’s too warm for it to fall as snow.

HRRR model 9 pm tonight – 4 am Thursday:

Thursday – Rain/Snow & Wind  Morning Low 38 / High 40

6a 41 . 9a 39 . 12p 35 . 3p 32 . 6p 28 . 9p 25

Temps. Our high temperature will occur in the morning hours. Temps will drop all day.

Winds will increase with the arrival of the cold front. Winds could gust as high as 30 mph by the afternoon.

Precip. As mentioned above, rain will be around in the morning. It could begin to change over to snow as early as 7 AM, but it’s unlikely to stick until noon, when most of the rain has passed.

Keep in mind it can snow even if it’s not 32F at the surface. Freezing temps above the ground create snow. Flakes won’t have time to melt as they fall into the slightly-above-freezing temps at the surface.

We expect little or no accumulation; however, north of downtown may see a dusting. Not a single weather model shows more than a half inch of snow.

This snow storm is looking more promising (for snow lovers) than Thursday.

GFS model Sunday 12 am – Monday 12 am:

It’s impossible to say how much snow. The models still don’t agree on the timing, which is everything when it comes to snow forecasting.
