After discussing with my teammate, we agreed that recent developments warrant an increase in our forecasting. However, given the timeframe, I stand by my previous forecast of bumping up only 1%.
Recent developments include Russian official's threat of nuclear war (https://www.reuters.com/world/europe/putin-ally-medvedev-warns-nuclear-war-if-russia-defeated-ukraine-2023-01-19/), which is accompanied by Putin's state of the union address, in which he announced that Russia is suspending the New START arms control treaty. In addition, Biden's visit to Kiev may further instigate Russian aggression.
Why do you think you're right?
The Russian government has successfully framed the war as "us vs them." Russia has successfully utilized propaganda and patriotism education to rally and sustain public support. Many of the methods used by the Russian government can also be found in Imperial Japan during the years that led up to the Pacific War.

Why might you be wrong?
A LA Times article points out that classical literature with subtle anti-war message has been growing more and more popular in Russia (https://www.latimes.com/opinion/story/2023-02-21/ukraine-war-russian-civilians-dissent). However, both my teammate and myself agree that with the given timeframe and Putin's record of approval, it will have to take a stronger negative sentiment for his approval rate to see a 30% drop.
