A nice little thunderstorm blew through part of Fort Collins today while Sandy and I were at church. It rained and hailed a lot. Driving, home, we saw some pretty good accumulations of hail (up to pea size) and some deep water that just couldn’t drain fast enough. Take a look at some of the pictures we snapped on the way home.

I’ve had a couple of people ask my why there seems to be a greater snowfall in Colorado during March and early April than during the heart of the Winter in December and January. Fort Collins receives an average of 12.4 inches of snow in March, compared to only 7.1 inches in December.
Warm air can hold more water than cold air. Anyone who has experienced a hot and muggy day knows this. Also, warmer temperatures are more likely to evaporate more water into the air.
Snow requires cold air, so that the moisture that comes out of clouds is frozen instead of just rain.
The most snow fall comes when warm moist air with lots of water combines with cold frozen air that causes snow. This is most likely to occur during early spring months. During winter, the air is too cold on average to hold lots of water, and during summer, the air is too warm to cause it to snow. In the spring months in between, there are just the right amounts of both to make it snow more.

The follow up question asks why it doesn’t rain more in the summer if warm air holds more water. Much of the warmer air is warm enough to hold onto the water causing it not to rain. If, however, the air is cooled, then water can fall out of those warm clouds as rain, just like squeezing a sponge.

Fort Collins this week is having a nice little January heat wave. Record high temperatures are reported and predicted this week, according to a Coloradoan.com article. Yesterday we hit 70 degrees, which was a new record. Today is also suppose to be the same, also breaking a record. This sort of heat is bound to quite global warming critics. I’ve very much enjoyed the weather, mostly because it allowed me to more easily fix my car.
But don’t worry too much, because this is Colorado after all. Snow is predicted Thursday night and Friday. And that is the way it goes. 70 degrees one day, snow the next.

One thing I like about the weather in Fort Collins is that the actual current temperatures can actually be higher than the high for the day. Right now, for example, it is 55 degrees, even though Google only said the high was going to be 42.
Tomorrows predicted high is higher than todays predicted high, I wonder if that means that tomorrow will be warmer than it was today, which would be nice because I want to go hiking tomorrow.

I’m from Oregon, and I’ve heard from my family about the recent storms and floods there. I’m also a ham radio operator, so when I read on slashdot how ham radio saved the day, I got excited. I remember 12 years ago being one of those ham radio operators helping out with emergency communications, and I remember listening in to the communications going out to Vernonia, Oregon and wishing that I could do more.

Here is a thought provoking quote I came across today:
I am asking that we stop seeking out the storms and enjoy more fully the sunlight
