FORECAST IN DETAIL


Raise your hand if you like autumn! The only thing wrong with the next few days is the indecision they will bring. Long or short sleeves? Jeans or shorts? Jacket just in case? High pressure heads our way from central Canada, bringing cool fall air with it. After several days of autumn bliss, another cold front brings shower chances Wednesday.

Today (Sunday): A much cooler day is on tap for us behind our latest cold front. Highs only reach near 70 to the low 70s as winds from the northwest, around 10-15 mph at times, usher in the Canadian air. Instability caused by even cooler air high above us may lead to some scattered afternoon clouds, but overall it’s a partly to mostly sunny day. Confidence: High

Tonight: As winds diminish and skies clear, temperatures plummet after sundown. We’re in for one of the colder nights we’ve seen recently, with lows mainly from the mid-40s (suburbs) to near 50 (downtown). Confidence: High

Tomorrow (Monday): Another fine day is on tap as high pressure settles in. In fact, it’s yet another nice weather day that makes it hard to stay inside at work if you have to. Under mostly sunny skies, highs again top out from near 70 to the low 70s. Confidence: High

Tomorrow night: It’s clear and cool again overnight as fall has definitely arrived. Bring a jacket if you’ll be out and about. Lows dip to the mid-40s to near 50 for the second straight night. Confidence: High

A LOOK AHEAD

Tuesday looks like another gem for us. High pressure begins to slide off the coast, but holds enough sway to keep us mostly sunny for one more day. Highs rise up into the sweet spot as well, maxing out in the mid-70s. Increasing clouds Tuesday night keep temperatures a bit warmer with lows mostly in the 50s. Confidence: Medium-High

By Wednesday, a new frontal system brings shower chances back to the area. It may be that any showers hold off until later in the day, but can’t be sure of that yet. Regardless, we’ll probably see considerably more cloudiness than the previous few days, but with warmer highs in the mid-70s to low 80s. Confidence:Medium
