Sunday was a cloudy, cooler, still somewhat wet day (0.21″ AM rain  and fog) with flooding still occurring in scattered, flood-prone spots in the region. Using the records from my old station, I had 3 years that were wetter than this year ( 68.35″ in 1996, 65.47″ in 1979, and 64.16″ in 2003). Whether this year can approach any of those figures is still a matter of conjecture, but we do have another wet period coming late this week that…

High temps almost reached the 50° mark after our first above freezing min since 12/4 (32.6°).

Sunday was cloudy and cold all day here in Rockville. Less than 50 miles to my south measurable snow fell (1-3″) in central VA and southern MD. Today was the first day of the season with sub-freezing temperatures all day. So the cold air was there for a snowstorm, the moisture was blocked by the cold, dry air from advancing into our immediate area unfortunately. Temperatures did not vary much today, only ranging from the upper 20s in the early…
