Crows are like pigeons, they don't rely on the sun 100% but use natural landmarks and magnetic fields in the earths crust. Hence they are quite capable of flying at night if needed, and have no problem on overcast days either
electrical storms (thunder and lightning) are the only things outside of hurricanes and tornados I've found that keep crows from moving LOL

Heyyy NH CRowshooter; years ago a bird watcher reported about 500 moving north one spring and it was snowing but it couldn't have been that thick though through Portsmouth.....I have shot crows in thick fluffy snowflakes in spring before...killed over a dozen for what that is worth at least in the good old days,. The farmers' helper asked if I would like some "spread" in front of my blind -SURE! And they began coming out of the then dump one by one!
Activity got hot after they heard that manure spreader!
Now NH Crow shooter-don't worry but do like this-get ready. we are in for some crazy weather this saturday-you might just be getting that hundred birds this year this week end! 99.1(FM) predicted snow flurries(this week end) so you know better than I what that means!

I shoot a lot of north bound crows in the spring of the year. It appears to me that crow migration is a very relaxed endeavour, Early birds migrating usually in pairs from just before sunrise until mid day. I feel it very doubtful that crows migrate at night like waterfowl and many species of song birds.
Later migrants are comprised of larger flocks, most last years young which are for the most past non breeders as the common crow here in North America does not breed until its second season. These make up sizeable spring roosts which fly daily to feed in areas and back.
Fall crows gather in great numbers and feed on agricultural fields gleaning waste grains and attacking standing sunflower crops sometimes causing great stress to sunflower producers as this crop is not combined until later in October in my parts. Southern migration again is a long very relaxed pursuit. Nothing like the here one day and gone the next as we often see with ducks and geese.
Just my couple cents worth from 40 plus years of killing crows...

Crows do NOT migrate at night, but are quite capable of doing so if needed.
They usually start moving at first light about 30-60 minutes before sunrise, and will often be still moving upto an hour after sunset,Mao long as there is still some light.
Where I am now crows are not migratory, but I have shot migratory crows during my travels. I've had them moving in heavy snow and rain, and even very thick fog (very exciting shooting, reaction time is a few seconds before they have gone again)

Redditch, one of my most memorable crow shoots was in heavy ground fog. Clear sky above but heavy fog clinging to the ground. The crows were flying above this and would suddenly appear above almost floating there. I have had duck shoots like this as well.
