I'm playing a sorcerer that for background reasons is married to the concept being a conjurer of storms and inclement weather. He has the air elemental bloodlines that I'm happy with despite the pitiful abilities because turning spells like burning hands into force lightning pleases me greatly. I spent levels 1-3 mostly color spraying things and would like to fit into my concept more closely now that I get to play around with 2nd level spells next session. I guess I'm just asking for suggestions for the future.
Uhhmmm... I'm just talking off the top of my head here. This may or may not be any good.
Better mechanically would probably be grabbing a god that does storms and then hopping into the evangelist prc. I'd recommend master of storms but you lose too many caster levels for what it gives you for you to still be good at casting spells related to storms.
Taking focus/eldritch heritage/improved eldritch heritage could add more storm related features from another bloodline. Concussive spell, dazing spell, merciful spell, rime spell, thundering spell, and toppling spell could all be metamagic that adds weather-like effects to your spells, but without reducers, I don't know how much help the feats would actually be.
I will think on it...
I might consider turning this character into a Cross-blooded Elemental (Air) / Storm-blooded Sorcerer. You could transform all attacks into electirc attacks and gain a +1 to the DC to resist them for doing so. Then I'd take the following bloodline powers:
1st - Elemental Ray (nice ranges touch attack)
3rd - Stormchild (2 resistances and mitigates the effects of weather)
9th - Elemental Blast (mess around with critters normally immune to electricity)
15th - Either ability (unlimited flight or limited 10x speed modifier that can be used offensively as well, but only for a limited duration)
20th - Elemental Body (immunity electricity, Crits, and sneak attacks)
For bonus spells:
3rd - Burning Hands (electricity)
5th - Scorching Ray (electricity)
7th - Protection from Energy
9th - Elemental Body (more for the movement than dmg/tanking, and note that you can take the form of any elemetal, not just air)
11th - Shout
13th - Chain Lightning
15th - Control Weather (thematic and potentially devastating fi used correctly)
17th - Summon Monster VIII (elementals only, but not just Air elementals)
19th - Elemental Swarm
As for 2nd lvl spells to keep in mind:
Blur (20% miss chance is always nice)
Fiery Shuriken (ranged touch attack)
Fog Cloud (concealment that you can partially ignore with Stormchild)
Scorching Ray (yes, you can get it later with your bonus spells, but why wait!)
Shatter (kill your enemies potions or other equipment and make caltrops at the same time!)

Also consider for a storm-based character using a Cross-blooded Elemental (Water) / Boreal Sorcerer. This essentially gains similar effects to the one described above, but specializes in cold dmg, gets better weather immunity, and my favorite SLA, Control Winds, as his 15th lvl ability.
I specifically call out Control Winds because the ability to create a full-blown tornado that can stop all ranged attacks, obscures vision for all combatants except you, can mightily toss enemies around for 6d6 dmg/rd for 1d10 rounds on top of falling dmg on a failed save (which they have to make every round), and can deal dmg as a swarm if seeded with enough daggers in an area with a radius of 40 ft/lvl, all under your complete control for 10 mins per lvl with additional cold effects (extreme cold and sleet that hampers movement) that you are immune to is insanely powerful.
