PM Update: Rain develops Wednesday, may change to snow late

Semi-springlike today, semi-winterlike tomorrow. After nearly touching 60, temperatures return closer to seasonal norms Wednesday. At the same time, low pressure approaches from the south, bringing rain, which may mix with and change to snow late in the day.

Through Tonight: Mostly clear skies early gradually become mostly cloudy. It’s chilly, with lows 30-35 (suburbs-city). Winds are mostly calm.

Wednesday: Cloudy skies with rain developing between late morning and mid-afternoon. Temperatures reach into the low 40s or so before easing back into the mid-to-upper 30s towards sunset.

Beginning in the late afternoon, a transition from rain to snow may begin in our far northwest suburbs and *may* eventually reach the District after dark - between 6 and 10 p.m. (if it happens). Accumulations will depend on the occurrence and timing of any changeover, temperatures and the intensity of precipitation.

Hurricane Sandy report: The National Hurricane Center today released an analysis concluding Sandy was *not* officially a hurricane when it made landfall, but had transitioned into a post-tropical storm just over 2 hours prior. The report found Sandy reached major hurricane status (category 3) in the Caribbean (in eastern Cuba) before the transition process and was the second costliest U.S. storm on record with estimated damage losses near $50 billion. Climate Central has more.
