Forecast: Sticky 80s Today, Stellar 70s Tomorrow
Saturday brings the likelihood of rain
FORECAST IN DETAIL
Early fall weather in our region can often produce rather changeable conditions, and the coming few days will exhibit just that. The word "unsettled" comes to mind, as we go from warm (to almost hot) and mostly cloudy today, to noticeably cooler conditions with ample sunshine on Friday, to what may turn out to be a pretty rainy Saturday...and then probably back to sunshine late Sunday into Monday.
Today (Thursday): Conditions today will closely mimic those we experienced yesterday. That means mostly cloudy skies (though with some filtered rays of sunshine at times), a stray shower or thundershower (most spots will remain dry) mainly before 3 p.m. - and continued warm afternoon highs well into the mid-80s. High humidity this morning will slowly diminish by evening. Confidence: High
Tonight: Mostly cloudy skies will linger during the evening hours tonight though some partial clearing is possible as we head through the night. Overnight lows will range from 60-65. Confidence: Medium-High
Keep reading to see what our weekend has in store...
Tomorrow (Friday): Friday's forecast calls for both noticeably cooler temperatures and more in the way of sunshine than today. A more northerly flow of air will hold afternoon highs to the low-to-mid 70s despite partly sunny skies. A front stalled out to our south will remain close enough that heavy cloud cover and showers may not be too far away -- so the day falls short of the criteria for the "Nice Day Sun"... Confidence: Medium
Tomorrow Night: Plan on a partly cloudy and dry evening Friday night, with a light easterly breeze from time to time. Clouds may quickly thicken towards morning. Overnight lows will range from 50-55 (downtown). Confidence: Medium-High
I'm sorry to be the bearer of bad news for Saturday, but a well-organized storm system approaching from the west is likely to bring overcast skies along with an increasing chance of showers (and even periods of steadier, heavier rain) as the day wears on. Afternoon highs likely won't make it out of the upper 60s. Saturday night may be rather rainy, so any outdoor evening activities are in jeopardy. Overnight lows drop to the upper 50s to low 60s. Confidence: Medium
It's possible that Sunday could be salvageable, but that's highly dependent on how quickly the aforementioned storm system pushes through. I think the first half of the day will feature more clouds than sun along with a 20% chance of a lingering shower. But I'm expecting at least partly sunny skies and dry conditions by the afternoon hours. Fingers crossed? Afternoon highs should be in the 70s. Confidence: Low-Medium
High pressure passes through the region on back-to-work Monday, allowing for considerable sunshine and dry conditions for a good part of the day. Temperatures should begin to creep back up, too, perhaps to near 80 for highs. By evening, though, a cold front may increase clouds and produce a shower or two. Overnight, it will probably become breezy and cooler, with lows in the 50s. Confidence: Medium
