I will try to do a nextday update for each day with the actual measured data from two local sources; and assign points for the closest forecast of Temps High&Low, Sky Conditions, Wind&Direction,and Rain variables. This should become a contest of sorts to see whose advanced forecast wins the most points for the Sat- Friday Week. (No points given if both forecasts are correct for a variable, or it does not apply.)

National Weather Service is the winner in this fair comparison.
Both forecasts were much less accurate after 4 days.
NWS omits Wind Speed and Direction for the remainder of the forecast days, SOOOoooo...to be fair, Wind variables will not apply starting Tuesday, but Sky Conditions and Rain-both forecasts show rain chances- may balance everything.
