FORECAST IN DETAIL


This weekend’s weather is going to bring near-normal temperatures to the area along with abundant sunshine. That spells fantastic conditions for any outdoor activities. It really only gets better heading back into the work week as well. Better if you like warmth, that is! Bottom line: One of the nicest weather stretches we can ask for is lining up quite well with all that foliage heading toward high color, or even peak out west.

Today (Saturday): The front from yesterday is well east, so dry air dominates, but the upper-level system driving the front passes close enough that we should see bubbly clouds, particularly in the midday and afternoon. There could even be a sprinkle, mainly north and west of the area. Given how dry the surface air is, even that’s going to be tough to come by. Highs reach the mid-to-upper 60s as light northwest winds blow as high as about 10 mph with stronger gusts. Clouds may make the Nice Day call close, but we’ll go with it. Confidence: Medium-High

Tonight: The air mass continues to be dry, and skies clear out nicely as the sun sets. Add in some lighter winds and we’ve got good radiational cooling (warmth escaping into the atmosphere) conditions. Lows tumble to near 40 in the colder spots, while staying closer to 50 downtown. Should be a good night for Orionid watching! Confidence: High

Tomorrow (Sunday): The upper-level storm system pulls away well to the northeast on Sunday, and that means our cloud threat should be minimal. In fact, it could be one of those mostly cloudless and crystal clear days. Enjoy that leaf peeping! Temperatures should be similar to Saturday, though maybe a degree or two cooler. Still mid-to-upper 60s. Breezes from the north and northwest may be gusty in the afternoon, generally 10-15 mph sustained on average. Confidence: High

Tomorrow night: Another seasonably chilly night is ahead as mostly clear skies dominate. Lows again near 40 in the coldest suburbs and could even end up in the upper 40s downtown. Confidence: High

A LOOK AHEAD

By Monday, a pattern re-alignment featuring a big upper-level low over the West Coast and a building high pressure over the East Coast is underway. For us, that means warm times ahead. A bit of indian summer? Well, not too warm as it is late October, but mostly sunny skies and highs ranging from near 70 to the mid-70s sounds mighty fine. Confidence: High

Tuesday brings more of the same. Rising off lows in the mid-40s to low 50s, possibly even warmer temperatures greet the afternoon. Sunshine rules the day as highs range from the low 70s to maybe upper 70s. Let’s shoot for mid-70s most spots. Any clouds floating by just add to the pleasant scenery. Confidence: Medium-High
