E145 First Officer reported the #2 Bleed temperature was low and the Anti-Ice System failed during cruise flight. The flight crew descended to a lower altitude to exit out of icing conditions and continued to the destination airport.

Narrative

While in cruise flight at FL310; the BLD 2 LOW TEMP EICAS message appeared. The pilot flying switched their MFD (Multi-function Flight Display) to the ECS (Environmental Control System) / AI page and confirmed that the Number 2 Bleed Temperature was outside of the Green Arc. The pilot flying took the radios while the pilot monitoring started to go through the QRH for BLD 2 LOW TEMP. After completion of the QRH for the BLD 2 LOW TEMP EICAS message; the WING A/ICE FAIL Caution appeared. Again the pilot flying took the radios and the pilot monitoring went through the appropriate QRH procedure. Due to a weather system along the crew's flight route that was known to have icing potential; the decision was made to begin a descent to 15;000 ft. as per the QRH and to [request priority handling] due to the higher-than-normal landing speeds required by the WING A/ICE FAIL. Emergency vehicles were requested as a precaution at ZZZ. The landing at ZZZ was successful and the aircraft was able to taxi to the gate without any assistance required.Have Maintenance perform more anti-ice bleed spot checks throughout the winter months or on aircraft that have been flying through icing conditions higher than the fleet norm to find potential failures due to use. Cause - low number 2 bleed temperatures and wing anti-ice failure in known icing conditions.
