Weather is incredibly important in aviation. Small fluctuations in weather can lead to a potentially hazardous flight conditions. I remember during one flight while I was practicing landings, air turbulence suddenly started increasing dramatically during the final leg of my landings. I turned on the ATIS/AWOS in the plane, but it kept repeating that the wind was only at 4 knots: perfect flying conditions. Yet, I had to execute all sorts of maneuvers during final like forward slips and crabbing in order for my plane to descend and maintain on course. When I got down later, I found out the bumpy flight was due to temperature fluctuations. The temperature rose dramatically causing uneven wind currents. Even small changes in weather can cause large disturbances. Always remember to check
aviationweather.gov before any flight!
