  Short term certainly, long term it's harder to predict: warmer air also has a much higher moisture carrying capacity, thus the cascading changes in weather patterns could also lead to better water circulation over and to currently dry areas. For instance the sahara was extremely dry (even more than currently) during the last glacial maximum, the african humid period started with the Bølling–Allerød warming / Late Glacial Interstadial (and as its name indicates, greened up the sahara area). Then it dried up again with the cooling of the Younger Dryas, before humidifying again at its end. It also underwent a dry spell during the 8.2kYa "cold event", before the african humid period ending entirely during the 4.2kYa aridification event (which seems related to the Bond Event 3).
