Christmas Gift of a Pattern Change.

Finally a pattern change and i'm not advertising this like Obama does. 
So far this December has had a big ridge of high pressure sitting on top of us giving us dry and foggy weather
the image below shows the jet stream winds and I have indicated the ridge of high pressure in red
How does this give us dry weather? This gives us dry weather by making all the moisture ride the jet stream over and around the high. Now this week starting Christmas day  that high pressure will move east and allow the jet stream to aim at us
The image above shows the forecast for the jet stream winds on Tuesday, notice how the strong winds (yellow color) are aimed strait at us.  
Christmas Forecast:
Christmas eve:  A weak warm front will move to the north of us  giving us a few showers but we should stay mostly dry.
Christmas day: A cold front following the warm front will come through giving us rain followed by showers.
Following Christmas the week looks pretty wet.
I probably wont be posting till after Christmas so....
