18z GFS model run 12/1/09

The latest run of the GFS model is in. The trend of the surface low pressure has moved a bit further west, which is good for us. The issue will be temperatures. The 00z model run will be in around 11pm and I will post again. The 00z model run is very important because the disturbance will be on land on the west coast. Models tend to do better when they arrive on the land. We shall see what happens, more to come.

On a different note, a big cold front will be pushing through tomorrow night associated with a low pressure that will be cutting to the great lakes (a lakes cutter). This will put us on the eastern side of the storm, or the warm side. What we can expect with this is temperatures to rise near 60 degrees tomorrow night. With the passage of the cold front, gusty winds and even a thunderstorm cannot be rules out. The system tomorrow night will bring around an inch of rain. When the front passes through, the temperatures should fall into the 50s and 40s.

So, keep posted for the upcoming model runs. tonights 00z run and tomorrows 12z run will be key in the developing system for Saturday. More to come as well about the possible rain, wind and tstorm activity tomorrow.
