Rainy Wednesday ahead

/ January 26, 2021 at 9:18 PM

Get ready for a soggy Wednesday as a cold front and upper disturbances combine to produce quite a bit of rainfall. Atmospheric moisture will be abnormally abundant for this time of year, allowing for most areas to receive over an inch of rain tomorrow. Temperatures will top out in the low 60s as a front sags south of the area.

Rain looks to begin to taper off in the evening hours as a secondary front pushes offshore. This will bring in cooler and drier air overnight, and by sunrise Thursday we should be seeing rapid clearing.

Tuesday: Warm with showers late

/ January 25, 2021 at 9:46 PM

After the warmest day since New Year’s today, we’ll get back into the mid-70s for Tuesday as we remain in the warm sector of a storm system cutting across Tennessee this evening. We’ll be under mostly cloudy skies with a few peeks of sun throughout the day, with shower chances increasing as the evening progresses ahead of what appears to be a very soggy Wednesday across the Tri-County.

The forecast high of 76° at the airport runs well above the normal high of 60° for January 26. The record high is 80°, set in 1949.

The week ahead: Warm and soggy start, cooler and drier finish

/ January 24, 2021 at 10:28 PM

The final week of January 2021 (already!) will start off fairly warm before returning to below-normal temperatures to head into the weekend. Forecasted highs in the 70s on Monday and Tuesday would be the first 70+ temperatures since January 1-2. This abnormal warmth will be swept away with a soggy storm system come Tuesday evening into Wednesday, though, bringing in cooler and drier conditions to close out the week. Then, the progressive pattern ushers in another storm system to possibly bring some rain and warmer temperatures back to the area as early as Sunday.

Partly cloudy skies for today with temperatures returning to the 60s

/ at 9:38 AM

After a Saturday full of brilliant sunshine and somewhat overachieving high temperatures, we’ll be back to the low 60s today with a few more clouds. You might notice it getting a little more humid as the day goes on, with winds switching to a more easterly/southeasterly direction this afternoon.

High-res guidance still wants to spit out a couple showers in the area very late tonight, but if there will be any rain, it would probably sprinkle in more toward Monday — and even then, there’s just a slight chance in the forecast right now. Will have more on this and the week ahead later tonight, but for now, enjoy your Sunday!
