Colder-than-average November to snap nearly two-year warm streak

November 29, 2012|By Scott Dance, The Baltimore Sun

November will end as the first colder-than-normal month in Baltimore since January 2011, according to National Weather Service data.

The month's average temperature will likely be more than 3 degrees below the typical 46.5 degrees. As of Wednesday, the average temperature at BWI Marshall Airport had been 43.2 degrees, unlikely to budge much with highs in the 40s Thursday and Friday.

This month, the mercury dipped below freezing at BWI on 13 days, compared with seven days last November and eight days in November 2010.

If the trend is to continue into December, it would take a major cold snap in the middle and toward the end of the month, judging by the forecast. The first three days of the month, at least, are expected to be well above normal with highs in the upper 50s and lower 60s.

Climate forecasters are expecting equal chances of warmer- and colder-than-normal temperatures in Maryland in December.

An earlier version of this post misstated when the warm streak began.
