Pond Boss Forums GENERAL QUESTIONS Pond Boss Cold water and warm air masses

One day last week my pond seemed to gain a little water without rain (maybe 1/8 inch). The water temp was in the mid 30's on the surface and a warm air mass swept in with dew points near 60 degrees. I think it was a case of "reverse evaporation", in other words, condensation onto the water. Comments?

The next day, we got a decent rain, which raised the water temp considerably, so no more measurements of possible condensation.

That most certainly happens, and when this occurs you will get an amazing influx of energy into the water, so the temperature will rise rapidly as well. A lot of energy is released when water converts from gaseous to liquid. Ever notice how fast your canned beer gets warm on a humid day vs. a dry one of the same temperature? How much water condenses on the can during this process?

When we get ice-out, it is usually due to days with wind and high humidity. Nothing melts snow and ice faster than a wind with a dew point above 32 degrees F.

It's happening again! Ponds had ice cover late yesterday afternoon. Woke up to rising temperatures (low 60's by daylight and still rising), strong winds from the Gulf. Ponds are definitely gaining a little bit of water, streets and patios sweating profusely.

Same here, dewpoints in the upper 40's after many days below 25F.
I always wonder how much "precipitation" we get during the snow melting process on days like this. After the snow is gone, and the ground has warmed to the dew point, it stops. I know that air masses that pass over snow pack or cold lake water get "sucked dry" and will stabilize, preventing storms from forming.

It was 72 degrees yesterday, with a strong wind from the south off the gulf. Cooler today, but still nice enough.
