I saw it and took a picture. It is flying out of Phoenix Sky Harbor International Airport. It landed at about 5:27 if that matters. It is a green tail livery that extends downward. The wings are above it like on a C172 however the engines are straight under the wings. The engines are fan engines, not props. It looks like the 146-RJ100 with only 2 engines total though.
Thanks for your help!
