The weather forecast for Eastern Ukraine shows that at least a full week of rain is coming up. This makes it more likely that the Russians will delay their upcoming offensive until late April at the very least, assuming that this time they actually want to spread out and advance across a front, instead of just driving down well-paved roads where they're easier to attack and ambush. The offensive could also start in early May. By then, the Russians will be in full control of Mariupol and the Donbas reinforcements will be well-rested and prepared for the coming fight. The best idea is definitely for the Russians to wait until at least April 20th before starting anything, just to have some time to consolidate and fully prepare. This new phase of the war should be more advantageous for them. The terrain in Eastern Ukraine is wide open, Russia will face fewer logistical issues, and the Ukrainians will have fewer places to hide, because none of the contested cities in the east are anywhere near as large as Kyiv. It's going to be an interesting month.
