The week ahead: Mostly quiet and seasonably warm

/ October 1, 2023 at 11:40 PM

A blocking pattern aloft will keep our weather relatively quiet for much of the week before a front approaches heading into the weekend, which might deliver the first real shot of fall weather to the area for early next week.

Cloud cover will generally be sparse through Wednesday as high pressure remains firmly in control across the area. Our mornings will generally start in the low to mid-60s with highs topping out in the low 80s each afternoon with plenty of sunshine to be had. Cloud cover begins to tick up a bit for Thursday into Friday as the aforementioned front begins to approach the area. It remains to be seen just how much moisture moves back into the area; for now, the forecast remains rain-free, though it wouldn’t shock me to see some shower or thunderstorm chances added as we head into Friday. Saturday should feature decreasing clouds, and then it looks like a reinforcing shot of cooler air moves in for Sunday that could knock temperatures well below normal for this point in the year. We aren’t into sweater weather yet, but we’re making progress!
