November is off to a colder-than-normal start despite a weekend warm spell that isn't expected to last through Tuesday. When the cold resumes, it could mean the end to a long streak in Baltimore weather.
As of Sunday, the average monthly temperature was about 44 degrees, 5 degrees cooler than normal. Given that normal temperatures decrease as the month goes on, November could threaten a trend of 21 consecutive months with above-normal average temperatures at BWI Airport.
BWI reached 69 degrees by 2 p.m. Monday, sure to tick up November's average temperature a smidge. But no records are in jeopardy -- it reached 78 degrees Nov. 12, 1879, in Baltimore, and the low temperature was a balmy 59 degrees Nov. 12, 1935, according to the National Weather Service. The morning started from a low of 40 degrees.
And no matter how much the warm spell heats things up, a return to cold temperatures is in the forecast after rain passes through Tuesday. Highs are forecast in the low 50s for the rest of the week, several degrees lower than normal, with lows about normal in the high 30s.
Climate forecasters estimate about a one in three chance of colder than normal temperatures for the latter part of November, according to the Climate Prediction Center in College Park.
Normal highs at the end of November in Baltimore are about 51 degrees, with lows around freezing.
