Ice Guys ISO . . . Winter

This winter's underperformance reduced the discussion in the Comments section last night to the subject of blog ads. However, a brisk cold front which brought thundersnow to Syracuse NY and a few other places in New York and Pennsylvania has brought Washington DC metro temperatures to below seasonable levels this afternoon.

It's also very dry. Dewpoints as low as the single digits correspond to relative humidites in the 20s. Along with northwesterly winds gusting over 30 mph, this has prompted the National Weather Service to issue fire weather watches in the area for the next several days. After a quick temperature rebound upward tomorrow, a stronger shot of cold will arrive on Sunday.

As the chart shows, however, the trend may be favorable for the snow lovers, but the calendaricity is not. Taken literally, the trend so far this month would take us to an average high in the mid 30s by the end of March. Like so many other trends here in the Nation's Capital, this trend is not sustainable. chart from NWS data, photo © Kevin Ambrose

Tonight and Tomorrow

Lows tonight under scattered clouds will be from 28 in the city to the low 20s in the colder 'burbs. Temperatures should bounce back to the mid 50s tomorrow before the next cold front arrives to lower them significantly on Sunday.
