Low clouds, mist, and showers have prevailed today along with much below average temperatures. Highs have only managed the low 40s, almost 20 degrees shy of the norms. Temperatures should moderate and skies brighten a bit by tomorrow afternoon, as we begin a warming trend.
Through Tonight: Occasional rain showers are likely, as low pressure develops off the coast and races northeastward. Before morning, a few of the colder, outlying suburbs toward Loudoun and Frederick counties may see the rain mix with or briefly change to sleet and/or wet snow. No accumulation is anticipated. Lows range from the mid-30s in the colder suburbs, to the upper 30s downtown.
Tomorrow (Friday): The day gets off to a cloudy and cool start, with some isolated showers possible (mixing with sleet/snow far to the west and northwest). As the day wears on skies should brighten, and even some breaks in the clouds are possible. Highs probably do about 10 degrees better than today, reaching the low 50s.
Record Sierra Nevada snow: The Associated Press ran a fascinating article yesterday about the incredible seasonal snowfall totals in California’s Sierra Nevada mountain range, creating a snowpack sufficient to all but end California’s three-year drought. More than 61 feet has fallen in the high country, with new ski resort accumulation records at Squaw Valley USA, Heavenly Mountain Resort, and Mammoth Mountain. Mammoth has so much snow it may stay open until July 4 the AP reported. Watch this neat video of the Union Pacific train clearing snow over the Donner Summit in the Sierra range for the first time in 13 years.
