Where did you get "VFR flight" from?
Bottom line is, you're transitioning from VFR-to-IFR to deal with deteriorating weather conditions in the en route phase of the VFR-flight, with subsequent VFR-landing at the destination airport.

The new EIR appears to offer me the ability to continue the journey without incident and arrive at my destination and land with the sun shining.
If ceilings and visibilities are heading downhill in the en route phase of your flight, being prepared (in advance of the flight) for tackling associated challenges is the key to have the safest possible outcome.
Your experience and comfort level might not be appropriate to handle the dynamics evolving around the en route flight envelope, and that's something you should understand.
The implication is that you might end up not enjoying that sunshine at your destination airport.
Appropriate & effective strategies to tackle adverse weather conditions are best ascertained on the ground in advance of the flight and not in the air.
