The weather in our fair town

 I follow a lot of blogs, but one of my favorites belongs to our state climatologist, Jim Angel. Jim writes in detail about our weather, taking into account the varying needs of our state and the wider meteorological picture.

The picture above is from his blog, and I think it explains a lot about our trend of weird and heavy storms, sometimes short in duration, which have been hitting our area -- and which may continue to bother us (the above map is a forecast for July). We seem to be caught between an above average temperature system to the south and a below average temperature system to the north. I don't remember much from 7th grade science class, but I do remember that when two different weather systems bump, they also grind, which can result in storms like we've been seeing this spring.

So what about our area? The EC for our area means that we have an equal chance of having average temperatures for the next month, above average or below average. That may not seem very specific, but... well, ok, it doesn't seem very specific. I guess it's better than being told definitively that we're going to be hotter or cooler than usual.

As for precipitation, we've had a wetter June than usual, but our July looks like it might not continue that way. Here's the precipitation map for July:

We're EC again -- equal chance of average precip, above average or below average. But since we're actually close to a below average area -- southern Illinois -- we may tend in that direction, too.

From weather.com, I found out that our average precipitation so far in the month of June is 3.67", but we're already at 4.43", with more rain to come this week. Our precip so far is actually close to the average precip for August, our wettest month in the year. It will be interesting to see if July does tend more dry.

Only time will tell, of course, and I would remind you that I am not a meteorologist -- far from it! Still, check out Jim's blog if you like talking weather.
