Updated timeline for Friday night into Saturday storm

(WTNH) — A lot of the weather talk this week is focused on the Arctic outbreak moving into Connecticut Thursday night. However, with a lot going on and not too many shopping days left until Christmas, this weekend’s forecast is also very important. A storm arriving late Friday night will bring accumulating snow before dawn on Saturday. It will be the biggest storm of the season to date at the Shoreline. Plows and sand/salt trucks will need to treat roads to keep them clear early in the day.

A change to rain is likely from south to north Saturday morning. The temperature will jump into the 40s at the Shoreline by mid morning, and the rain may be heavy at times before winding down in the afternoon. You can expect a lull Saturday night before another round of rain Sunday morning. See the detailed timeline below to help you plan your weekend.

Friday Evening
Clouds thicken, but dry conditions. Very cold, with temps in the teens inland and low to mid 20s at the Shoreline.

Friday Night (after midnight)
First flakes are likely between 2-4 AM. Steadier snow arrives before sunrise (7:12 AM). Expect to see enough snow to shovel and plow by 7 AM in most or all of CT. 1-3″ should be on the ground by dawn.

Saturday Morning
Snow changes to rain at the Shoreline (I-95 corridor) between 8-10 am, while it continues snowing inland until around noon. The wind will increase at the Shoreline to 15-35 mph as warmer air slowly moves in. The temperature will likely reach 38-42° at the Shoreline by 12 pm. It will be in the low to mid 30s inland. Most of the snow accumulation will have ended by noon on Saturday, with some flakes lingering into the early afternoon in far N CT. Road conditions may improve at the Shoreline by late in the morning.

Saturday Afternoon
Rain tapers to showers/drizzle/mist by 4-5 pm. Temperatures in the mid 30s inland to low 40s Shoreline. Travel will not be too difficult by late in the day, especially at the Shoreline.

Saturday Night
Damp and raw in the evening. Temperature in the mid 30s to low 40s early in the night, but rising to the low 40s inland and near 50 at the Shoreline by dawn. Steady rain is not likely before dawn on Sunday.

It will be a mild start to the day with temperatures in the 40s and 50s. Rain showers are likely from mid to late morning through early to mid afternoon. It will stay mild while it rains, but once it ends, you can expect the temperature to fall quickly, and it will get below freezing again between 6 pm inland and 10 pm at the Shoreline. Any remaining snow, slush or standing water will freeze!

Thankfully, the weather looks a lot quieter in the early to middle part of next week. That’s good news for anyone who wants to finish (or start) their Christmas shopping!
