weather is important military information, if you know the kinds of visibility that's available, the winds, if it's raining, etc, since for example stealth planes don't tend to play nicely with rain, so you need to plan missions around that. if the roads are bad you need to know what the weather conditions are going to be like or you risk not being able to supply your troops, and if the weather is bad enough your troops can't march, or at least won't make much progress. this all also applies to the enemy, and so if you know the weather you can get a good idea of what they can do.
So the military might indeed emergency launch a mere weather satellite.
So if fighting an opponent that can down satellites it can be important to get replacements up quickly, especially since most countries can't bring down many satellites.
