After-Christmas Markdowns

Steve Scolnik @ 4:10 PM

The low pressure area which brought rain to the Washington DC metro area on Christmas has deepened as it moved northeast to the coast of Maine this afternoon. Northwesterly winds behind the low have been gusting over 30 mph at times as temperatures hover in the mid 40s under mostly cloudy skies. A few isolated sprinkles or snow flurries have been widely scattered about.

The last several days of near or above "normal" temperatures have given an after-Christmas markdown to the temperature deficit for the month. The monthly average so far of 34.7 is lower than the last few years, but considerably warmer than the 31.8 in 2000. The corresponding heating degree day total is also marked down, to 24% above the long-term average. As Jason explained earlier, temperatures should be mainly above average this week with most of the cold air remaining bottled up in Canada.

Tonight and Tomorrow

Lows tonight will range from the upper 20s to the low 30s under clearing skies. Tomorrow will be partly cloudy with highs near 49.

Tsunami Review

Today is the anniversary of the devastating Indian Ocean tsunami. The final death toll will never be known exactly, but the catastrophe killed over 200,000 people, mainly in Indonesia and Sri Lanka. That is more than 5 times the number killed by the catastrophic explosion of Krakatoa in 1883, and about 200 times the number killed from Katrina. Tomorrow night, PBS will rebroadcast the NOVA® program "Wave that Shook the World", originally shown in March. The show is on WETA (26) at 8pm locally. Major funding for NOVA® is provided by Google, which also provides ads to help support this site.
