PM Update: Clouds to clear, then a terrific Tuesday

A very weak cold front is sweeping through the region, producing some scattered clouds and even some light showers, mainly in the north and west suburbs. Once the front passes, high pressure builds back into the region. Sunshine dominates the skies Tuesday.

Through Tonight: A shower may dampen a few spots before dark, but shouldn’t last long. Skies gradually clear after midnight, with seasonable lows from near 40 in the cooler suburbs to the upper 40s downtown.

Tuesday: A very pretty fall day. Morning 40s steadily warm into the mid-to-upper 60s by mid-afternoon under blue skies. Winds are light, from the northwest at around 10 mph.

Friday night and Saturday forecast: I mentioned in my forecast this morning that there was uncertainty in the outlook for Friday due to the possible development of low pressure to our south. The latest models are going gangbusters with the development painting a cold and wet picture Friday night and into the day Saturday. You may even hear us throwing the snow word around a bit, but - at this point - mainly for the mountains.

Pollen update from Walter Reed: Grasses are LOW. Mold spores are HIGH .
