1st forecast for game day. I will only update as changes warrant.
At the top of this thread I mentioned it may be somewhat cold for game time, although I questioned the model output I went with it anyway. However in the back of my head was the forecast for two very important oscillation's and how they teleconnect thus affecting the weather. They are the Pacific North American Index (PNA) and the Eastern Pacific Oscillation (EPO). When the PNA is in its negative state that translates to a trough in the west with colder than normal temps. When the EPO is in it's negative state cold air is likely to be filtered down into the lower 48 from the northwest territories and points beyond. Where it goes can be affected by the PNA. If you have a positive PNA that should build a ridge out west allowing the cold air to filter into the central US and points east, as we saw last winter. Now because the PNA and the EPO are forecast to go negative that should send the cold air down over the western to central US, and in theory pop a Bermuda ridge. The models were not showing that a few days ago, but now they are catching on. Therefore things have changed, those of you going to the game will miss the start of the deep freeze but you will be returning to it.
If it were me heading out for the game to catch early morning activities I would be wearing jeans and Gopher sweatshirt, however I would also have a maroon and gold t-shirt underneath so that I could chuck the sweatshirt by game time. For those of you that are comfy in shorts in slightly cooler weather go ahead a wear them.
Morning temps around 52°, by the end of the first quarter we should be looking at temps between 68-71° with dew points hovering around 60°. There could be a cloud deck around 5000 feet according to the GFS forecast sounding. The other three models used I don't have access to their soundings as of yet. Models used the ECMWF (European), the GEM (Canadian), The GFS (American), the GFS Parallel (American). All are in fairly good agreement this far out, thus confidence is above average.
Go Gophers!!!!
