NO dear, even if it is an existing system, even if it is a small range missile the warning had to be issued as per protocol.
Regarding range, more chances are that an medium to long range missile will be test fired from Sonmiani and the given coordinates of area cordoned off means the range to be around 1500 Km. If it is fired from Tilla Joia - Jehlum, this increase the potential range significantly but any test from there is unlikely. That range is primarily used by KRL that developed the Ghauri series of missiles and Ghauri III have been canceled some years ago.
So in case that it do turn out to be a new system then a longer range Babur cruise missile is most appropriate fit. Provided there is no error in our calculation of range.
So again, in light of the coordinates shade, it seem it will be some old system (warning had to be given in that case as well) with range of around 1500 to 2000Km, lets see if there is anything AT ALL!!
