I'm taking the liberty of re-ordering the elements in your post so that I can more easily point out my issues with it. I will do my best not to change your intent, but if I do, please correct me.

They are the initial target, so I'm a little curious how they could be their own saviors, but carry on!
Summoner has Eyes of the Eagle cast on him.
Psychic Seers Pre warning of attack, Summoner summons up the storms rendering flight impossible.
Okay, so being forewarned of a possible attack, Summoner summons a bunch of storms. I'm not aware of any storms that make flight impossible, but for the purposes of this post, I'm willing to accept that such storms exist and can be summoned as you've described.
The Summoner having Eyes of the Eagle benefits nobody since the storms will impair his own vision.
Conventional Radar.
There's no reason why the Unholy couldn't have imported this from another dimension with appropriate power supplies. However, given the tremendous storms that the Summoner has just summoned, I'm curious how effective you think these will be.
Techno-wizard Radar systems
If this is actual radar, then it'll be impaired the same way as the conventional radar is. If it's something else, you'll have to describe its capabilities.
Bio-wizard detection Systems(Eyes of Eylor or another device that's similar)
Hmm...and risk the Spurgorth learning of wormwood and the Unholy? Seems unlikely. Is there another source for this type of equipment?
Skyrider Picketers.
Demonic Spotters( Who can cast invisible superior on themselves+Eyes of the Eagle)
Or any other unit as spotters listed in Wormwood for the Forces of Darkness. Since units are constantly on patrol, it's beyond a doubt that some one would spot a unit of PA's flying. Most don't have an operational altitude high enough to render them unseen to ground forces.
And somehow these units aren't impaired by the tremendous storms that make flight impossible that the Summoner has summoned? I bet these units are plotting against the Summoner as we speak
And just to point out something from a post earlier in the thread, the phase world PAs have gravometric flight which has no ceiling. They can fly above any storm or even outside the atmosphere if they desire.
Lets not forget the Unholy and his Host themselves(they can fly)
I am skeptical that they would put themselves directly in harm's way, but I welcome the idea since that makes finding them to kill them easier.
Plus Summon Storm, Tornado, Ice Storm, and other similar spells are area effects. They don't need to be targeted, just set them off in an area, sit back and grin as the infantry are chewed up by the demons while smoking a cigar and enjoying a job well done as Air Defense.
So you're tormenting your own demons with these storms. Interesting strategy. And what infantry are your demons chewing up?
Most of them have ranges measured in mile radius. You don't always have to see something to kill it. Crashing into the ground will inflict massive damage on the pilot, either seriously injuring him, or killing him, leaving the bad guys with some dinged up(possibly ruined) Tech goodies to scavenge.
Except the PA never had to fly through the storms since you summoned them before the PAs even arrived. They simply flew above the storms. The only troops being harmed by the storms are your own.
Depending on how high the storms go, it's possible that the PAs can still reduce the crawling towers to rubble only now the tower's defenders can't event attempt to defend the tower since the storms prevent them from flying up to engage the PA.
Please let me know what I missed. Specifically, please direct me to the storm spells you intend on using. I found Summon and Control Storm, but that doesn't do what you've described and Tornado travels along the ground, so you must have some other storm spells in mind.
