Armenia announced a full counter-offensive about an hour ago, so I expect we will start seeing a dramatic change on the battlefield soon, as this presumably means the Armenian regular Army is being committed. It is also likely to strike into Azerbaijan proper, given the amount of attacks we have seen inside Armenia already.
As @
Easo said, Azerbaijan seems to be firing on population centers, presumably to force evacuations. Armenia's typical reaction to this is to clear the Azerbaijani side of the border and enforce and exclusion zone, as they did in 2016 and 2005. So I expect to see the fighting intensify a lot over the next 24 hours, as Armenians go on the offense to roll back the recent Azeri gains, and then some. This is likely also the excuse Turkey has been waiting for to officially get involved militarily.
