The week ahead: Coolest weather thus far this season for mid-week

/ at 6:17 PM

We’re back on the temperature rollercoaster this week as a front moves by on Tuesday, which will usher in the coolest airmass thus far this season for mid-week. (Certainly a far cry from watching another tropical system, that’s for sure.)

First, though, we have one more day in the 80s before the front gets through. It’ll be the warmest day of the week, starting around 60° and warming to the mid-80s in the afternoon. We’ll get within spitting distance of the record high of 88° set in 1943 and 1990, but we should stay below that mark. Much like Sunday, expect another day of unfettered sunshine on Monday.

The front moves by Tuesday with a little more in the way of cloud cover but little else. That will cool highs off to the mid-70s, roughly 10° or so cooler than Monday. We really feel the cooler airmass on Wednesday, though, as temperatures fall to the upper 40s in the morning, only reaching the mid-60s in the afternoon. Thursday runs even cooler in the morning, with mid-40s reaching back to the mid-60s once again. No rain’s expected with this frontal passage, and we’ll see primarily sunshine more than anything else.

After one more start in the mid-40s, a warming trend commences Friday as highs climb back to the low 70s. Saturday will run a little warmer, with highs in the mid-70s, and we’ll run even a click warmer on Sunday as well, with plenty of sunshine throughout.

Weekend forecast: No weather worries

/ October 11, 2024 at 9:29 PM

We have an outstanding weekend of weather ahead as high pressure remains in control. After our first low in the 40s Friday morning, Saturday starts back in the upper 40s once more, but winds will start to swing around to the south and that will begin to help moderate the airmass a bit. Expect just a few passing clouds Saturday afternoon, but otherwise, lots of sunshine will be the rule.

Sunday will be a warmer day. We start the day in the mid-50s, warming back into the low 80s in the afternoon under mostly sunny skies. It’ll be a very comfortable low 80s, though, as humidity will be a non-factor with dewpoints in the mid-50s.

I hope you get a chance to enjoy this wonderful weekend of weather!

Friday & the weekend: Tons of sunshine and a quick shot of fall

/ at 6:08 PM

Get ready for the first low 50s of the season starting tomorrow morning! Lows are forecast to bottom out around 50° — and into the upper 40s further inland — for the first time since April 24 on Friday morning. This will yield to highs in the low 70s in the afternoon under predominantly sunny skies. The northeast breeze will still be elevated in the morning, gradually winding down as we get into the evening.

Saturday gets off to a similarly chilly start, though the airmass will begin to moderate as highs climb back into the upper 70s in the afternoon with nearly uninhibited sunshine expected. The warming trend continues Sunday, with a slightly warmer start in the mid-50s warming to highs in the low 80s in the afternoon.

The only weather-related concern of note will be the risk for some minor flooding around the afternoon high tides Friday and again on Saturday as the northeast breeze persists. However, major flooding disruptions do not appear to be in the cards.

Finally, there’s nothing in the tropics we need to be worried about. In fact, it may be a while before we get any more rain. A dry front early next week could usher in even cooler weather, well below normal for mid-October standards. Watching it…
