For the first time since November 19 (18 days ago), temperatures averaged below normal today, only reaching the mid-40s after morning lows in the mid-30s. Tonight and tomorrow, the cold air moderates slightly, bringing us back to near normal levels or slightly above. But chillier than average air is back for the weekend. It’s dry for the entire stretch.
Through Tonight: It’s mostly clear but for a few high clouds. Overnight lows range from the mid-to-upper 20s in the colder suburbs to the mid-30s downtown. Still no freeze for Reagan National.
Friday: Skies are mostly sunny, with some high, thin clouds possible in the afternoon. A light breeze from the south ahead of a weak cold front boosts highs into the low 50s, which is slightly above average levels in the upper 40s.
CSU hurricane forecasters ax December pre-season predictions: Citing a lack of skill in December forecasts for the coming June to November hurricane season, the Colorado State team of Phil Klotzbach and Bill Gray has stopped issuing such forecasts effective this year. That’s after a 20 year run. Eric Berger, the SciGuy, provides more of the rationale on his blog.
