FORECAST IN DETAIL

Other than a potential shower this morning (maybe lingering into the midday particularly north), we’ve got a fine weekend on tap to ring in 2012. Make sure you soak up the rays and the temperatures running a good 10-15 degrees above average, because it’s going to get significantly colder heading into the first work week of the new year. We had to get a real taste of winter at some point! And this one does not look to last long.

Snow Potential Index: 1 (→) - Just about no chance of anything notable, but some flakes may fall as cold air moves in early next week.

New Year’s Eve (Saturday): Southwest and west breezes keep the warmer air flowing into the region. Any clouds and perhaps a remnant shower should be out of here pretty quick as the morning progresses. So, we’re talking partly to mostly sunny skies for the afternoon. Those breezes are running about 5-15 mph during the day, probably strongest midday. And temperatures reach the mid-to-upper 50s for highs. Confidence: Medium

Watchin’ the ball drop (Tonight): Plan on seeing lots of stars (unless you live in the light polluted city area) on your way to wherever you’re going to see 2012 arrive. Temperatures near 40 to the low 40s around midnight eventually fall to the mid-30s to near 40 by sunrise. Confidence: Medium-High

Keep reading for the forecast through next Tuesday...

New Year’s Day (Sunday): 2012 begins on the mild note 2011 finished on. There may be some passing clouds here and there, but overall it should be sunnier than not. Winds are up more of the day than Saturday, but not super strong, just about 10-15 mph — with gusts toward 30 mph — from the southwest. High temperatures are pretty similar as well, making the mid-50s to near 60. Confidence: Medium-High

Tomorrow night: Partly to mostly cloudy skies rule the region as the much anticipated cold front approaches. Still, truly cold air should not arrive right away. That keeps temperatures from falling much below a range of near freezing in the suburbs to the mid-or-upper 30s downtown. Confidence: Medium

A LOOK AHEAD

Cold air comes rushing in on Monday, but the core of the air mass is still filtering in. With winds maybe nearing 20 mph or so sustained, and higher gusts, you might not care too much that it’s not as cold as it could be just yet. Highs ranging from near 40 to the mid-40s — maybe set early in the day — should feel considerably colder as those winds roar from the northwest. There could be an errant snowflake but don’t count on much making it over the mountains. Confidence: Medium

Tuesday may be the coldest of the cold, at least for high temperatures. Clouds are perhaps more numerous thanks to the cold pocket aloft and a peak of lake effect snow to the northwest causing a bit of spillover. Highs ranging from near freezing to the mid-30s will again be only part of the story as winds continue to gust, at least early, from the northwest. As with Monday, we can’t really completely rule out a snowflake or two, but they should mainly be found to our northwest. Confidence: Medium
