It's a mild start to meteorological winter with fog and a few clouds expected to yield mostly sunny skies on this Dec. 1.  The fog is thickest this morning around the Bay and the Tidal Potomac with visibilities of just 0.1 miles in Lexington Park and 2.0 miles at Reagan National.  High temperatures today should be similar to yesterday's 54 degree reading, but even warmer numbers are likely for the next three days.  With this morning's backdoor cold front in retreat throughout the day as a warm front, the coast will be clear for a southerly flow of milder, moist air to move into the Washington area.  The higher dew points are noticeable this morning and will be a big factor over the next few days as nighttime lows drop only into the mid to upper 40s.  Daytime highs are likely to be in the mid 60s both Monday and Tuesday.  There are two chances for showers in the short term as two cold fronts could bring rain in the overnight hours on Sunday and Tuesday.  The frontal passage late Tuesday will bring cooler air back to the area as daytime highs Wednesday through Friday will dip into the upper 40s and low 50s.

NOTE: Nov. 2012 goes into the record books as the only month this year that was colder than average.  It was a full three degrees below the seasonal norm, making for the greatest departure from a monthly average since way back in Dec. 2010 when the average was five degrees lower.  Enjoy this mild start to the chilliest of seasons!
