I was flying today and went from 110 knots airspeed with an indicated groundspeed on the gps of 65 knots to 160 knots airspeed, I was set up in cruise when suddenly the plane started to climb from 3000 to 3200 and was on a heading 330, surface winds at the AP were 310 20 knots gusting to 32 knots. No change was made to the power settings until the plane started to climb and I only tried to correct the altitude for about a minute and then noticed the high 160 knots airspeed and reduced the power at that point, and while correcting the increase in altitude from what have been a pretty strong updraft my decent rate was only about 400fpm at the time so didn't effect the airspeed that much as something from the updraft.

Just wondering why an updraft could cause such an rapid increase in the airspeed, I am thinking something associated with the updraft produced a strong tailwind for a short period of time, but note sure on what causes this?
