Weather Rewind - January 20-26, 2013
Last week's temperatures went from the proverbial blowtorch to the icebox after Sunday afternoon's cold frontal passage. We averaged out to 7.3 degrees below average last week, our coldest week since 2011. The last five days averaged eleven degrees colder than average or colder! Included in the litany of cold stats is our coldest overnight low of the winter so far at 12, our coldest day on Wednesday with a 22 degree high, and two snowfall events. We picked up 2.9" of snow in Philadelphia this past week at the Airport although some locations ended up with over four inches between Monday's band of snow with the reinforced arctic boundary and the Friday clipper.
This week's weather has pushed our monthly temperature departure from six degrees above average to 2.6 in just a few days' time. We'll likely end January above average but nowhere near what we were at earlier in the month.
Winter-to-date, we're at four inches of snow in Philadelphia, which equals what we picked up last winter for its entirety. We can't say it's worse than last winter!
Nationally, the west was warm while the eastern half of the country was generally colder but after that warmup a week ago a good chunk of snowcover in the middle of the country melted away. Nationally, we're just north of 40 percent snowcover through Sunday morning, which is still fifty percent better than last winter's total through January 26th.
