Be sure tho to take it all with a large grain of salt--what you see on those sites has just as much chance of being wrong as being right.
As Uncleromulus always says, if they had any confidence in their own 10 day forecasts they would issue them once every 10 days.
Watch though as each day's forecast in that 10-day window changes every day you look at it!!!!
BUt here's hoping you do wind up with EXCELLENT weather!!
