Friday and the weekend: Another round of chilly temperatures incoming

/ January 14, 2021 at 9:02 PM

Clouds and eventually showers will return to the weather picture during the day tomorrow as a cold front approaches the area. Temperatures will get to the low to mid-60s before the front swings through. Winds will also kick up with the frontal passage, so be ready for gusts near 30 MPH through Saturday.

Speaking of Saturday, clouds will be clearing the area, but we will once again turn chilly, with highs only topping out in the low 50s. The aforementioned wind will make it feel even colder, too. Most of us away from the coast will see freezing temperatures Sunday morning (along with mid-20s wind chills). Highs will once again only reach the low 50s in the afternoon despite plentiful sunshine. These temperatures will be the result of a large cold-core upper low that will be swinging through the upper Midwest into the Ohio Valley and eventually New England over the weekend, sending a plunge of rather chilly air all the way south into Florida.

The sun returns for Thursday

/ January 13, 2021 at 9:52 PM

After a stubborn cloud deck kept temperatures significantly lower than expected today, we will finally get these clouds out of here once and for all and enjoy a mostly sunny day on Thursday. Highs will top out around 60° in most spots. It’ll sure feel nice to get this gloomy stuff out of here, that’s for sure.

Near-normal temperatures and some sun for Wednesday

/ January 12, 2021 at 9:51 PM

We’ll warm up a bit on Wednesday as a little more sun works into the area with high pressure at the surface. Cloud cover will be reinforced at times by some upper-level energy moving through the area, but despite that, we should touch 60° in the afternoon, which is right on the warm side of a normal high temperature for mid-January.

Watch for patches of fog in the morning causing dips in visibility at times. Fog should mix out by 9am, giving way to the aforementioned partly sunny skies.

Rain overnight gives way to a little bit of afternoon sun Tuesday

/ January 11, 2021 at 8:59 PM

As low pressure moves eastward along the Gulf coast, we’ll keep the risk of showers and drizzle around through early Tuesday afternoon before high pressure begins to build in and cloud cover slowly breaks. Watch for areas of fog in the morning; be sure to use low beams and be prepared for visibility to drop quickly.

We should see a little sun before Tuesday’s gone, and there will be much more where that comes from as we get into the rest of the week. Temperatures could top out in the upper 50s, but this certainly will be dependent on how quickly the cloud deck can scour out.

The week ahead: Showers to start, then a few days of 60s

/ January 10, 2021 at 10:48 PM

The week ahead will be characterized with a few showers to start before warming up and clearing out in the second half. Clouds will increase overnight into Monday, with showers potentially developing over the ocean and moving inland starting in the afternoon. Shower chances will continue into Tuesday as a wave of low pressure affects the area. Once the disturbance clears the area, we’ve got a few nice days to close out the work week, with temperatures topping out in the low 60s each afternoon. A cold front will swing through early Saturday that may bring a shower or two, but other than that, we’ll cool back to around or a little below normal for the weekend.
