Return to Early Winter
Matt Ross @ 1:00 AM
After an impressive mild spell, we will return to more seasonable conditions through the week, with temperatures averaging near normal.
Today
Sunny, Crisp. Today will be sunny, but cool. Afternoon high temps will be around 50 degrees, a few degrees above normal.
Tonight and Tomorrow
Sunny, Seasonably Cool. Tonight will be our coldest night in almost 10 days. Lows will drop to the mid to upper 20s. Wednesday will be sunny, cool and breezy. Afternoon highs right around normal in the mid to upper 40s. See Jason's forecast for the rest of the week and weekend.

December Notes
Yesterday was the last day in an impressive 8 day warm spell that began the afternoon of Monday, December 11th. The temperature averaged almost 10 degrees above normal during the period, more like mid November. Our average high during the streak was 60 degrees with an average low near 40. It was capped off with an impressive record high day yesterday which averaged more than 20 degrees above normal, and felt like early Fall. Currently, we are running about 2.7 degrees above normal for the month.
In our 2006-07 Winter Outlook we called for December temps of normal, leaning slightly above. I still think that this result has a better chance of verifying than not. But, I would lean more toward the slightly above normal, as it still looks like cool to cold shots will be progressive over the next 7-10 days. I believe this will be a transition or stepdown period to more sustained cold as we finish December and head into January.
Snow Lover's Crystal Ball 
Next Chance of Accumulating Snow: Tuesday, December 26th - Thursday, December 28th
Probability: 10%
Potential Impact:
Commentary: Anything that falls over Christmas weekend looks like rain. However, behind that we are going to get a shot of seasonably cold air for at least 2-3 days. Additionally, there are some very preliminary indications of a storm in that timeframe. The pattern, while not great for snow, is still sufficient to support snow if all the "ifs" come together. As has been the case all December, do not hold your breath. Right now I would categorize the chances of snow as still unlikely as indicated by the cautious 10% above, but at least worth some passing attention until things become clearer.
