Saturday: Warm, muggy, and occasionally quite rainy

/ January 1, 2021 at 10:32 PM

Well, 2021 is definitely getting off to a muggy start. After tying the daily record high of 80° for January 1, we’ll start Saturday in the mid-60s — several degrees above the normal high temperature — as unusually muggy air persists ahead of a cold front. Expect showers and perhaps a thunderstorm or two to develop by afternoon, which will temper highs a bit (but not before reaching the low 70s). Some pockets of heavy rain are possible within stronger thunderstorms, but no severe weather is anticipated and the flood threat remains low. When all is said and done, some spots may have picked up 1-2″ of rainfall.

The front will get a move-on during the day, though, and by Sunday morning should be clearing the area, leaving behind quiet and generally pleasant January weather with slightly above-normal temperatures for the first work week of 2021.

A foggy and showery New Year’s Eve celebration ahead

It’ll be a warm but overcast night across the area as we flush 2020 and try again in 2021. Temperatures will hold in the mid-60s as the clock turns midnight, owing to the muggy airmass in place. Said muggy airmass will allow fog to develop later this evening as well; some patches of it may become dense, and NWS notes in its discussion that a Dense Fog Advisory could be required.

Watch out for a few scattered showers coming in from off the ocean this evening as well, but the bulk of the activity looks to remain northwest of here as rain continues to fall into the remnants of the cold air damming regime. Depending on where the front ultimately ends up, we could see that enhanced rain risk come a little closer to 17-A, but we’ll keep an eye on it.

Overall, it’s not the worst weather to end 2020 with, especially considering how this year has gone. I wish you all a very Happy New Year!
