If temperatures surpass 60 degrees Wednesday, as forecast, it would be a fourth consecutive year that such a mild temperature had been recorded at BWI Marshall Airport. They could also rise above that mark Tuesday, earlier than expected.
(UPDATE: BWI reached 60 degrees by 1 p.m. Tuesday.)
Here are some of the recent warm spells in January:
- January 2012 came amid the sixth-warmest winter on record at BWI, and thermometers reached 60 or higher four times. Twice the mercury reached 66 degrees. The average monthly temperature was 38.3 degrees, more than 5 degrees above normal.
- January 2011 hit 60 degrees once, on the second day of the near year. Overall, though, the month was colder than normal by about 2 degrees, the last colder-than-normal month at the airport until November 2012.
- January 2010 reached 66 degrees once. Otherwise, the month averaged out to a normal 33 degree average temperature.
Record highs for Baltimore in January are mostly in the lower 70s, with some in the upper 60s. Average highs are in the lower 40s, with lows in the mid-20s. January's average temperature so far this month is about 2.5 degrees above normal, at 35.5 degrees.
The warm-up could begin a bit earlier than expected, with a frontal boundary stalled to the northwest of the Baltimore area. On the north side of the boundary, foggy conditions that had been forecast for this morning remain, while sunny skies are peeking from behind the clouds to the south, including in downtown Baltimore.
That sunshine caused BWI to jump from 48 degrees at 10 a.m. to 56 degrees by 11 a.m. Forecasts had previously called for foggy and cloudy conditions to hang over the Baltimore area Tuesday, keeping highs in the upper 40s.Copyright © 2015, The Baltimore Sun
