Can I fish a tw frog in the rain? water temps are 72 and its 75 outside cloudy and rainy, some vegetation in the lake

 

go for it

Ya can fish any lure at any time In any conditions!

Of course. One of the best days for numbers I ever had was overcast and drizzling rain. I caught bass all day on a Torpedo.

You might need something to get their attention though. Maybe a popping frog or a prop bait.

Went fishing in the rain on monday and had the best day I've ever had here in VA, there wasn't much cover to throw frogs tho. I had them all hit on a wacky rigged worm. 

rainy day frogs are deadly in cover and over open water
