Another frigid start is on tap for Tuesday, but we start to see signs of warming Tuesday afternoon, with 60s returning by Wednesday. Next rain chance is roughly Thursday afternoon through Friday morning with temperatures remaining generally around or above normal.

While it won’t be as windy as it was on Monday morning, we still have quite a frigid start queued up for Tuesday as lows drop back to the low 20s in the morning, with some upper teens possibl…

Bitter cold to start the week will thankfully be short-lived as temperatures moderate back to the 60s by midweek with the only significant rain chance looking to arrive Thursday into early Friday.

The well-advertised cold snap is underway as Arctic air pushes into the area, with air temperatures expected to fall to around 20° in the morning. While the most gusty winds should subside overnigh…

The plan for the weekend is reasonably straightforward: You'll want to get out and about on Saturday as temperatures head to the mid-to-upper 60s, as it's going to start turning much cooler Sunday afternoon, with pipe-busting cold expected Monday morning.

My advice to folks for this weekend: get out and about Saturday as much as you can, soaking in what passes for warmth during this rather chilly December, because another shot of very cold air is en…

A brief warmup is in the cards for Friday and again on Saturday before a front moves by with some showers Sunday. This front will usher in a bitterly cold Arctic airmass that'll plunge temperatures into the low 20s by Monday morning.

Another round of cooler air arrives for Thursday, but at least we won't be dealing with another round of freezing fog. Temperatures moderate heading into the weekend, but the next Arctic blast is teed up to arrive later Sunday.

Another dry front will come through overnight with a reinforcing shot of cooler air for our neck of the woods, but at least we won’t be starting the day with freezing fog like we did this mor…

After another cold start on Wednesday, we'll see temperatures climb a bit, though it'll still be on the chilly side of normal, especially Thursday as a reinforcing front kicks up the cloud cover a bit. A warmer-than-normal weekend awaits, though.

The sun takes center stage Tuesday, but it sure won't feel like it as cool air moves in throughout the day, keeping highs pinned to the upper 40s after a subfreezing start. We'll turn warmer for the second half of the week, though.

We’ll finally shed the cloud cover that’s punctuated the last several days on Tuesday as high pressure builds in from the northwest. The aforementioned high pressure will drive even coo…

08/12/2025

After a rare dreary weekend, the sun will slowly return to our skies on Monday before more doggedly reasserting itself on Tuesday as high pressure builds in behind a dry front. After another front and maybe a few showers Friday, temperatures look to plunge for the weekend.

Dreary weather continues for Sunday with a few more showers possible. Skies will begin to clear on Monday as drier air punches in, with much more sunshine by Tuesday.

We’ve had some much-needed rain over the past few days, but it’s certainly not made for the best outdoors weather, either. Unfortunately that continues on Sunday, which will decidedly n…
