Memorial Day Holiday Weekend Forecast
 
GSL Slip Renters and Marina Users.
I have had some requests for my opinion on the weather forecast for Great Salt Lake this weekend.   So I have provided a forecast for Memorial Day weekend.  Realize that I am not a meteorologist so this forecast may not be worth the garbage that it may be.  The forecast is based on my interpretation of all the weather charts I look at during the day.  It is also focused on the general marina area but does have some applications for the whole Great Salt Lake  So here it is for what its worth:

Thats it.  Take it for what its worth.  Its mostly my guess.  Keep informed by local weather sources such as NOAA, radio and television.
 
Give me feedback.  If you would like the forecasts for holiday weekends to continue, I will try to do them.  If you don't, I will be happy to stop them
