  • There seems to be no end to this weather.  Just when we think that spring is here, Mother Nature reminds us that it is still too early for flowers and butterflies.  We had intermittent snow showers all day W […]

    • Quite a cold end to 2017/beginning to 2018 for you, Kevin! Good descriptive write-up of the goings-on there for the month of January.

      Did you measure any snow yesterday? I know you were just on the western edge of accumulations from the current Nor’easter.

      • Thanks Jeff I had 0.2” of snow on grass only at midnight with light snow falling and 33.4 temp I got another 0.1” after midnight. Greater amounts fell further east and northeast like Annapolis and Elkton See more details in my daily Wx post on my WT page Did you check out GLOBE yet ? K

    • Karl, being rather new to the PNW (nearly 4 years), it is certainly interesting to experience the “early” winters here, especially having grown up back East (where winter is still occurring as I type), then being 16 years in the San Francisco area (where summers are “late,” maxing in September/October). I look forward to your next blog on this subject. Though I am a snow lover, I am ready for Spring to hit full-force.

    • The year 2011 was an interesting one, in that our hottest weather of the year came in early September (much like parts of California often experience!). Also we had a ton of low-elevation snow in March 2012. Sometimes the “normal” seasonal timetable gets skewed…

  • On Saturday, storm conditions started to wind down, with partial sun returning and winds starting to lessen throughout the day. No more power or cable outages on Saturday thank goodness. After early AM lows in the […]

  • Winds really died down here on Saturday, and power outages have stopped here, but right now there is a power problem at the Navy Stadium in Annapolis where the Caps and Maple Leafs are having a special “outdoors” game on the frozen over football field.
