Can ChatGPT forecast the weather?
Yes, ChatGPT can create weather forecasts, but the real question will be their accuracy.
People have started exploring how to use ChatGPT and other artificial intelligence methods to experiment with forecasts. This is not surprising as we have always needed weather forecasts and humans have used many techniques over the decades. Some of the earliest forms of forecasts were short rhymes, and, although memorable, were often of uneven quality. Continue reading
Were May and June unusually dry in Madison?
While we all contended with the remarkable and dangerous smoke in the sky this past week, we also wrapped up a record dry spell in Madison’s history.
The 61 days of May and June 2023 were the driest May and June ever, with a paltry 2.01 inches of total precipitation falling. The next closest rival on this ignominious list occurred in May and June 1992, when only 2.65 inches of rain fell during the two months.

In fact, in 1982, the last zero degree (or colder) night was not until April 7, the latest date in the last 83 years. Continue reading
How unusual was the past weekend’s fantastic weather?
It is a fair bet that we would get near universal agreement that this October has been pretty spectacular here in southern Wisconsin. Through the 29th, the average temperature has been exactly normal, and we have had only 11 days … Continue reading
What can happen to hurricanes when they move into the mid-latitudes?
Hurricanes are large-scale, organized storms that form in the tropical latitudes.
They are fueled by the enormous amount of heat released when water vapor, evaporated off the warm tropical ocean surface, changes phase to liquid and ice in the thunderstorm clouds of the hurricane.
They are smaller in areal extent than the storms that commonly affect us in the mid-latitudes here in Madison. Continue reading
