Narrative:

We were at FL370; in IMC; thunderstorms around the area; and light turbulence. The captain's airspeed went to 0 knots; and mine was off as well. Then our altimeters also were not correct. We contacted ATC; declared an emergency; and started running checklists. The captain was hand flying at that point; and we were trying to keep altitude; and confirming with ATC our altitude. We needed to stay at FL370 until clear of weather; and diverted to ZZZ. On the way to ZZZ; the radios started to squeal; and we had to communicate with ATC through another airliner. Once we started descending for the airport; everything seemed to come back to normal; and it was uneventful after that.
