43 F. high on October 27, 2012.
Coating of slush can't be ruled out early Tuesday, but most roads will probably stay wet tomorrow.
Heaviest rain comes late Wednesday into Thursday morning.
Yesterday I cheered my amazing wife on as she ran her 4th Marine Corp Marathon in Washington D.C. She keeps trying to win a 22 year old Marine. Me? All that cheering, standing, texting & picture-taking? I was exhausted. But I'm OK (thanks for asking).
Minnesota meteorologists are about to embark on their own personal (winter) marathon. "How many inches of snow in my driveway? Please be specific."
Humbling but true: every weather scenario, every storm is different. To be able to predict how much snow will fall we look at the precise storm track, moisture content, the degree of vertical motion within a column of air, temperatures in the lowest mile of the atmosphere, ground temperatures (in case there's melting on contact with warmer surfaces), the location of the dry surge (the dreaded "dry tongue") as well as a myriad of other data.
4 new model runs are issued every day, and we examine trends from run to run. Do the models agree? If so our confidence level goes up.
The latest guidance suggests enough warm air aloft for a light sloppy mix changing to all rain tomorrow. A little slush is possible early Tuesday, with a plowable snow for the Dakotas. A surge of steadier rain arrives late Wednesday into Thursday AM, but it may dry out a little for Thursday PM Trick or Treating (risk of a passing zombie).
November starts out gray & chilly but 50s return in a week. Hardly Indian Summer, more like a not-as-cold front.
12 Strange Weather Features Of Superstorm Sandy. Yes, Sandy set a number of "firsts". AP has an eye-opening list, reported at The Fresno Bee; here's a clip:
3. SNOW: This is the first time the National Hurricane Center ever listed snow or blizzard in their warnings. Three feet of snow fell in West Virginia.
4. GREAT LAKES: It is unusual for 20 foot waves, large surges and tropical force winds to be recorded in the Great Lakes for a coastal tropical storm, but it happened with Sandy.
5. ENERGY: NOAA's Hurricane Research Division has an experiment program that measures integrated energy of a storm's surge and waves on a 0 to 6.0 scale. Sandy reached 5.8, passing Katrina as the highest recorded so far...

One of the worst of these episodes, and one that helped focus attention on U.S. air pollution, was the choking, deadly smog that covered Donora, Pa., in the Monongahela River Valley, 20 miles southeast of Pittsburgh from Oct. 27 to 31, 1948..."

Open Letter — October 2013
To: Diane Carol Bast, Executive Editor, The Heartland Institute
Re: Release of Climate Change Reconsidered II: Physical Science
Dear Mrs. Bast,
Thanks for sending out your helpful, if somewhat self-congratulatory, memo to so many US teachers (PDF). Its subject is important: the NIPCC’s gripping sequel “Climate Change Reconsidered II”, a title as original as the ‘Not the IPCC’ nomenclature is witty.
While I’m sure nobody would question your organisation’s motive in wanting to reach out to so many young and impressionable minds (and I’m sure very few will conflate this initiative with Heartland’s sturdy defence of the embattled tobacco industry during the 1990s) there are some minor issues that might demand attention....
