I was on CNN's web site and was a bit stunned to see this article regarding a deadly weather pattern setting up across the central US over the holiday weekend. Wow, that's a grim headline that incites concern and even fear.

As you probably know the next 2 weeks are statistically the hottest time of the year anywhere in the central US. I looked into the forecast highs on the EURO and this is what it shows through the holiday weekend . A lot of...

I was poking around a bit today in the wide world of weather that I live in. I came upon the sea surface temperature anomalies over the tropical Pacific. This is something I start paying attention to in the mid-summer because invariably it plays a role (sometimes a big one) in the type of fall and winter the Midwest experiences. Note the cool waters that exist near the equator in the eastern Pacific.

The cooling in that area has increased signific...

Sometimes to get a quick overview of where temperature trends are leaning, I pop up a meteogram of the latest EURO or GFS. It's a down and dirty way of seeing the future without doing the analysis. More often than not you get a solid idea of the short term but the further out you go, (as most of you know) the less accurate the skill scores.

With that much heat and humidity, instability was high but forcing was lacking and most of the thunderstorms avoided my local area. That was not the case where intense thunderstorms battered parts of...

In the summer of 1885, sky watchers around northern Europe noticed something strange. Sunsets weren't the same anymore. The red and orange colors people were used to seeing were still there, but those familiar colors were increasingly joined by rippling waves of luminous blue.

At first they chalked it up to Krakatoa which had erupted two years ear...
