Weather has been kind of overcast but they are expecting it to clear up tomorrow and get better for the weekend.
Crowds have been moderate, depending... The parks are busy on Saturday (obviously being the weekend) but not so bad otherwise. You didn't say how long you would be here for, but next week is the annual press events. Epcot closes at 3pm on the 9th (so MK is staying open later). Also on the 9th is the premier of "Wishes" the new fireworks show at MK.
Any other specific question I can help you with?
