It is expected that the sun would be out but it is possible that Boeing can hold off on engine start due to the low ceiling.

I'll be reporting and updating this post throughout today to document the first flight of the first 747-8. The aircraft successfully completed it taxi tests on Saturday in preparation for today's flight.
Currently the weather in Everett is 44 degrees F and cloudy but around flight time the weather is expected to be partly sunny with a temperature of 46 degrees F.
The plan is for the 747-8 to take off and test the initial aircraft response. The aircraft will return to Everett after its first flight. After a couple of days, Boeing will base this aircraft from Moses Lake, International Airport for the remainder of the initial airworthiness tests. After the 747-8 has completed this milestone RC501 as well as RC 521 and RC 522 will all be flown out of Palmdale, California for the remainder of the test flight program so as to not to interfere with 787 testing going on at Boeing Field. Typically, Boeing runs test flights out of Boeing Field but with two major programs entering flight test, Boeing decided to separate the two test flight programs. Please check back here during today for updates on the first flight. You can also follow me on Twitter.
