Firstly, just do me a favor and walk outside. Refreshing right? Thats thanks to winds from the south and being on the Western Side of High Pressure. Expect these conditions to continue for most of today. However, expect clouds to increase later tonight and early tomorrow as a storm system approaches from our South and West. Your Christmas morning and early Afternoon should remain mostly cloudy and dry, but then expect rain to begin Around or just After noon time. The rain should continue (heavy at times) to near midnight. Monday should be a dry day.

A summary of the Holiday Forecast can be seen at the Top of the Page.


After this, the forecast has once again become uncertain. Originally, we were forecasted to be very cold after the Holiday Weekend. However, this has become questionable. Taking a look at some of the models, you can clearly see why. What we are seeing here is called an Alberta Clipper. These storms come from Canada and drop down into or close to the United States. In certain situation, they will tug extremely cold air down from Canada. This was the case being printed by the models. This would account for one thing needed for a major snowstorm, a Cold Air Supply. However, models now show the storm falling apart too far north to bring down any notable cold air supply. Therefore, the Cold air may be a problem.


Another thing we need (or could use) for a substantial snowstorm is the NAO being negative. Currently the NAO has risen from its Negative state to near Positive. This isnt good for the Eastern Snow hounds. The Negative NAO usually leads to a trough in the east and a stormy pattern. Another index we could use, and one that has been helping us out alot this year is the PNA. A positive PNA almost always leads to eastern troughiness, and it is currently Positive. However, this argues against the Currently Positive NAO. At the right I attacthed the 500mb Anomalies..you can see the Positive PNA and the Positive NAO.



What we are looking at here is a sticky situation for substantial snowstorms in the next few days. We have a few arguing indexes and points, and it we would have to have everything go absolutely correct at the exact time to get one. In regards to yesterdays Euro, i dont buy it one bit. Take a look at the Pac jet pumping and the short wave racing down. There is NO way that the Low Pressure can slow down and bomb off the coast like that, I just dont see it.

In conclusion here (yeah, i know i veered off the holiday forecast) I think we are in basically a nuetral pattern for snowstorms...that is, not too favorable or too hostile. However, looking into the far future, We may even see a blocking mechanism set up twoards the end of December, and this could possibly set us up in a good situation for early January. Once again, the Holiday Forecast is at the top of the Webpage. Have a great Holiday Guys.
