For the 15th straight day, temperatures climbed to above normal levels, reaching the mid-50s under delightful sunshine. But that streak most likely ends tomorrow, as a little disturbance zips through the region, offering up a period of light snow - primarily in the afternoon and evening. Accumulations will mostly occur in the colder west and northwest suburbs.

Through Tonight: No weather problems tonight - so, kids, do your homework. Lows range from the upper 20s in the colder suburbs to the mid-30s downtown.

Wednesday: Clouds increase during the morning with a (30%) chance of light snow in the western suburbs during the late morning. Temperatures rise to 35-40 by noon. Snow increases in coverage and intensity during the afternoon (70% chance), but may start as rain, especially south and east of the District. By late afternoon, most places should have snow, with temperatures in the low 30s in the colder suburbs and mid-30s elsewhere.

Snow continues through much of the PM commute before ending between 6 and 10 p.m. from west to east. Temperatures range from 31-34 after the sun sets, raising the possibility of some slick roads, especially in the colder north and west suburbs. Total accumulations range from under 1” in the immediate metro region to up to 2” or so well north and west of town - especially in spots with some elevation.
