Once this fog and overcast burn off, forecasters say, we should have a mostly sunny day with temperatures rising well into the 60s. With the bulbs coming up, and the willows starting to blush, it almost feels like spring, which arrives officially Friday morning around daybreak. I expect to hear the spring peepers any day now. In fact, they're late. Anyone hearing them yet?

That's not to say we're not going to have some crisp mornings ahead. There's a cold front headed this way. It will slide across the region Thursday, preceded by increasing clouds, a rising chance for showers tomorrow and cooler temperatures - only in the 50s Thursday and Friday.

But behind the cold front there is clear sailing ahead. Skies will clear Friday and stay that way into next week. Temperatures will rise out of the 50s as we get into a southwest flow around the new high, and settle around 60 degrees for the weekend. That's about 5 degrees above the averages for this time of year at BWI.

But we're not done with chilly weather entirely. The overnight lows Friday into Saturday, and Saturday into Sunday are predicted to dip into the 20s as winds calm and clear skies allow heat accumulated during the day to radiate back into space.

March is a time for temperature and weather extremes as the sun moves north and rapidly warming sub-tropical air collides with still-cold arctic air. Here is roundup of what we've already seen just this month:

March 2:  Record daily snowfall set: 4.7 inches, breaking the previous record for the date of 3.7 inches set in 1969.

March 3: Record low temperature for the date - 10 degrees, breaking the previous record of 12 degrees, set in 1925.

March 8: The low temperature of 54 degrees set a new record high minimum for the date. 

March 8: Record temperature range over 5 days tied - 68 degrees. The mercury at BWI rose from 8 degrees on Mar. 4 to 76 degrees on Mar. 8. That tied the record set March 8-12, 1990, when the temperature rose from 18 degrees to 86 degrees.
