Yes, Storm can "see" the weather as you described, however that doesn't expalin or justify how she would have the cognitive ability, reaction time and reflexes to dodge something traveling at the speed of light. She has the limitations of highly skilled humans, nothing more.
All of this aside, Thor's control of the weather is based on magic, as is some of the "lightning" he strikes with.
Do YOU believe Storm could take Thor?
Let me get this straight:
Character has been around SINCE the 80's Using her powers to fly faster than a human being could control such,(In space piloting one of the Acanti at HYPERLIGHT Speeds)... generate and fire lightning at speeds faster than her opponent to even see it coming ,.. Pages of her deflecting ENERGY in most forms being thrown at her up to and including the phoenix -
*Pause*
Yet we can't explain or Justify how her energy sensing / manipulation could be "fast enough to do something about incoming lightning?
BECAUSE U YAHOO'S Believe that that part of her mutation operates at the same speed you do algebra on a calculator?
(Chuckle)
With that kind of logic MOST of the Xmen can't use their powers,... Nightcrawler couldn't telport,... Iceman couldn't create an Ice Anything instantly, The telepaths and Telekinetics would be reduced to doing things as fast as mundanes do,.. negating their powers.
Nope - You can't reduce Storm to how fast YOU think she can do something - against what SHE ALREADY HAS SHOWN just to win an arguement.
On your question about the Versus?
Only One place where storm whups Thor.
Near the center of the Galaxy.
There the amount of power she has available to manipulate exceeds the amount of energy that Thor has available as the God of Thunder.
points:
1. It's Canon that Storm has Manipulated STARS,... (Not A Star,.. but Clusters.)
2. It's Canon that she has absorbed and discharged enough stellar energy from glacatic center to destroy a Starship.
3. Thor has NEVER been shown to manipulate Any energy effects off planet, nor does he absorb or redirect energy outside of the stuff with the Hammer.
4. Thor has Limits that are inherent in him as far as energy manipulation. Storms limits are not in manip but in CONTROL.
This means:
That on EARTH or anywhere else short of Galactic Center where Ororo doesn't have access to more ENERGY than Thor trucks around with naturally,... Thor wins.
Galactic Center - She Beats his Azz.
Period.
No real dispute on this unless you want to ignore (counting on Fingers) 25+ years of X-men History.
