January 2015 - Not as Cold & Snowy as Last Year, But Sill Cold & Snowy

January 2015

Compared to last January, January 2015 wasn't as cold or snowy, but it was still colder and snowier than average, with a mean temperature 2.7 degrees below average, and snowfall more than double the month's average (16.9" vs. 7.0").  It was also the wettest January since 1999.  What follows are the four key stories of the month:

 

  • A typical January is five degrees colder than December, but this year it was 11 degrees colder as December was on the mild side (3.2 degrees above average).
  • There was a "January thaw" of just one day, on Jan. 5 when it was 56°/41°.  After that day the "warmest" temperature for the rest of the month was just 43°.  By contrast, January 2014 had a thaw of five days.
  • The rainstorm of Jan. 18, which drenched the area with 2.10", was the biggest rainstorm in January since 1999.
  • Of course, the biggest story of the month was the blizzard that fizzled during the last week of the month, giving the City "just" 9.8" rather than 24"-36" that had been predicted the day before the storm moved in.

Your point about the lack of a true "thaw" is well-taken. I believe it's now been over a month since the temperature has gone higher than 43 degrees, and based on the 10 day forecast, it doesn't look like we will exceed 43 degrees any time soon (unless some warm air sneaks in tomorrow or early Monday). I'm wondering if that's anywhere near close to a record.

Hi Ken, one of my next posts will be talking about this very subject. Going back to 1970 the longest streak has been 52 days, during the winter of 1977 (Dec. 21, 1976 - Feb. 10, 1977). Presently (as of Feb. 7), there are nine streaks longer than this winter's.

Thanks for the reply, looking forward to the article.

I actually do remember that 76/77 stretch although I didn't know it was any sort of record. There was stuff going on in my personal life (long since over) during that exact same time period that made the weather even more unbearable.

This winter has been such a big disappointment with one after another snowstorm fizzling (and going to Boston!), so this streak is the only thing that's sustaining me. And I got a bit nervous on Sunday when I saw temperatures in Philly, Baltimore and DC were in the 50s and 60s.

since November first, 15.78" of precipitation fell, the wettest Nov-Dec-Jan combination since 1987 (when 18.82" fell) and the seventh wettest on record. all but one of the six wetter such three month combos have occurred since 1973 (the other year was in 1915).
