FORECAST IN DETAIL Ah, fall, with its dry air masses and shorter days. This means temperatures markedly respond higher as the sun rises, and dip quickly after sunset. Dress in layers! Might we also squeeze out some needed showers later tomorrow or tomorrow night? Today (Sunday): After a freeze in many spots, chilly morning temperatures slowly rise through the 30s and 40s (bundle up if out early!). Mostly sunny skies dominate, boosting highs to near 60 to the low 60s. Note our air mass continues to be very dry (dew points in the 20s). Be sure to drink extra water if exercising outside, and don’t be surprised if you start reaching for the lip or skin moisturizer. Breezes from the southwest are light, around 5-10 mph. Confidence: High Tonight: You shouldn’t have much of a problem viewing the supermoon! Temperatures bottom out just before dawn, ranging from near 30 in the coolest suburbs to near 40 downtown. Widely ranging temperatures like this are common when winds become calm and skies stay predominately clear. Confidence: Medium-High |
