FORECAST IN DETAIL
Since Friday, which felt more like March or November, temperatures have gradually edged upwards. We take the next step higher today, but it’s still cooler than normal. But to cap off the three-day weekend, it feels just right – tastefully bridging the cooler regime of days past with the hot weather on the way.
Today (Monday): Throw on an extra layer if you’re out early, but by mid-to-late morning jackets not required. Beautiful sunshine all morning long, with temperatures near 70 by midday. Afternoon highs reach the mid-to-upper 70s. Some clouds may start streaming into the area by late in the afternoon. Confidence: Medium-High
Tonight: Partly to mostly cloudy skies as a warm front approaches the area. I can’t rule out a shower or thunderstorm (20 percent chance), but it’s mainly dry. Lows range from the mid-to-upper 50s in the cooler suburbs to the low 60s downtown. Confidence: Medium
