PM Update: Sunny, mild Saturday, rainy Sunday; ISS flyby this evening

The weather word of the day was tranquil, with sunshine, light winds, and relatively mild temperatures. Saturday’s similarly calm, while warmer – perfect for shoppers or spending some time outside. But plan to spend much of Sunday inside as rain falls for the balance of the day.

Through Tonight: Temperatures fall back quickly under starry skies. Most spots are into the 30s by 7 or 8 p.m., with lows ranging from the low-to-mid 20s in the cooler suburbs to 30 or so downtown. Light winds.

Tomorrow and tomorrow night (Saturday): While we won’t come close to matching last Saturday’s 72, most of us will take sunny and 55 on December 28 (temperature range: low 50s northwest of town, upper 50s south of town). Winds are light from the southwest around 5-10 mph. Increasing clouds Saturday night with lows in the mid-30s in the colder suburbs to near 40 downtown.

Sunday: Rain develops early-to-mid morning and may be heavy at times. An inch or so of rain may fall. The clouds and rain hold down temps, with highs 40-45. Winds initially are from the south, shifting to out of the north later in the afternoon.
