She has been running new Michelin X-ice snow tires this winter, but inflated to sidewall max (44 or 51 PSI, I forget which). She also runs a nearly invisible upper grille block that helps with warmup slightly.
Keeping your speed below 65 MPH will help, but she doesn't do that (she's not a hypermiler lol).
A dying hybrid battery will lower your mileage.
Winter does take a larger toll FE-wise on more fuel efficient vehicles, especially hybrids.

Hey thanks for all this info.
Yeah I have Bridgestone Ecopedia or something like that. I keep them at 50PSI. My lifetime average is 45. My last few have been in the low 40s. I really need to put in some pipe insulation foam to act as a grill block. My daily commute is all city driving, only about 15 minutes.
