1977: Record lows were set across central Minnesota with lows in the teens to single digits below zero. Montevideo had the coldest temperature of 18 degrees below zero along with Long Prairie at 16 degrees below zero.
1820: Ft. Snelling is in the middle of a three-day blizzard that would dump nine inches of snow.
A Dry Cold
I have to laugh when friends in Arizona describe a "dry heat" in the summer. But they have a point; moisture in the air makes a big difference. It's why 100F is tolerable in Scottsdale but horrific in Ft. Myers.
When I tell people I'm from Minnesota they look at me like I'm either slightly mad, or a descendent of Sir Edmund Hillary, the first man to conquer Mt. Everest. "How do you survive out there?" The reality: our coldest fronts blow dry (sunny) Canadian air into Minnesota, making it almost tolerable.
The coldest I've ever been? Chicago and Manhattan, surrounded by water - with higher humidity levels. Damp clothes allow the chill to penetrate through layers of clothing, making it feel much colder, much faster. It's true.
Long-range guidance shows another shot of numbing air after December 5. Until then Canadian air is tempered by a faint Pacific breeze, meaning highs mostly in the 30s the next 8-10 days. Good news for Upper Midwest travelers: a couple of scrawny clippers this week, but no slush-potential until early next week.
An ill-timed east coast storm dumps heavy rain east of I-95 with snow for the Appalachians the day before Thanksgiving. Travel updates and details below.
* Dallas/Fort Worth still on track for significant ice Sunday night into Monday morning, impacting commutes and facilities.
* Heavy snow/ice overspreads Arkansas, northern Mississippi and Alabama Monday into early Tuesday; a few inches of icy accumulation expected.
* Still on track for heavy rain and urban flooding up and down the eastern seaboard Tuesday into Wednesday; all-rain expected east of I-95, some slush western suburbs of D.C., Baltimore, Philadelphia and New York City, with very heavy snowfall amounts from the Shenandoah Valley and Appalachians into central/western Pennsylvania and much of upstate New York by Wednesday. Thanksgiving travel will be impacted/disrupted.
Summary: The storm we've been tracking and briefing on for many days now is still very much on track. Ice will impact metro Dallas and Fort Worth tonight and Monday morning, with hazardous winter travel possible over much of the Deep South Monday and early Tuesday, spreading up the Appalachians by midweek. East of I-95 precipitation will fall as (heavy) rain with a potential for urban flooding, especially Wednesday.
Plowable amounts of snow are expected from Roanoke to Leesburg, Winchester, Frederick, Hagerstown, York, Harrisburg, Lancaster, Reading and Allentown into northern New Jersey. This may be a crippling snowfall for the higher elevations from near Elkins and Charlestown, West Virginia to Pittsburgh, State College, Elmira, Syracuse and Rochester, New York. Pre-Thanksgiving operations will be impacted all up and down the east coast with conditions rapidly improving on Thanksgiving Day. Yes, major storms prefer to come on or before major holidays - the biggest travel week is just too tempting a target, I fear. We'll keep you posted.
