Can you cross a lake breeze front by foot? because i was just down the block with southwest?

Question

winds, and i walked back to the east the winds were dead calm kept going and the winds were east

Answer 1

Yes, it's possible.  It's most likely moving faster than you can walk so you would have had the same effect if you were standing still.  It is a sharp feature like that where the windshift would be noted over a short distance/time.

Another possibility is that it was a gravity wave.  If you are near mountains and a cold front moved through in the last several hours, this can happen.  Do you think a cold front moved through recently?  Did you see lines of clouds in a very regular pattern above you?  It would look like a row of clouds, then a mile of two of clear, then another row of clouds etc.
