There is sky texture in valve\halflife.wad. Or you can make your on sky texture. Create brush with this sky texture where you whant to have sky. Then (if your are using WC tools) go to Map properties, find enviroment map graph and enter your enviroment (for example city1 for default cs_assault sky). If you'll leave it blank sky will be cliff like thing. All enviroment maps are placed in cstrike\gfx\env directory. If it's still unclear i strongly recommend to visit VANDAL'S ALMANAC (http://www.karljones.com/halflife/almanac.asp).
