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:
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.
