I suppose it’s only fitting that our four day streak of picture perfect days ends on Friday the 13th. Already, clouds are rolling in this afternoon although it’s still pretty nice out there. It remains dry through the evening but widely scattered showers enter the picture late tonight and tomorrow before increasing in coverage and intensity this weekend.

Through Tonight: Skies are partly to mostly cloudy this evening and then trend toward mostly cloudy after midnight when there’s a 20-30% chance of showers. The clouds hold up the temperatures, with lows 54-59 (suburbs-city).

Tomorrow (Friday): It’s more cloudy than not throughout the day. Fortunately, it’s more dry than not as well, but a shower or two can’t be ruled out - especially as you head west and during the late afternoon and evening. Temperatures are fairly comfortable, with highs 70 to 75..

Climate rap video gets mixed reviews: The Australian TV show Hungry Beast has produced the edgy climate rap video “I’m a climate scientist”(caution contains profanity, i.e. possibly NSFW). The outwardly anti-climate skeptic video has drawn predictable reactions in the blogosphere. The liberal Climate Progress calls it “hilarious” and Gristlist says it’s “awesome/awful” and “give them props for going balls to the wall”. The conservative/skeptic blog WattsUpWiththat calls it a “farce”. Watch the video | lyrics (again, contains profanity)
