Week #5: Weather Forecasting, and Synoptic and Mesoscale Weather

This week we cover weather forecasting and severe events of thunderstorms and tornadoes. I often say forecasting is more of an “art” than a “science” as the atmosphere is never static. Forecast models involve complex mathematics and physics, but ultimately it is the forecaster who must interpret that data. I hear people complain that forecasts are “always wrong”, but in fact, they are often correct. For example, I have had students comment how there was a forecast for 30% chance of rain, but it didn’t rain 30% of the day/30% of the area, etc. The fact is that the forecast is that there is a 1 in 3 chance it will rain that day for that forecast area – if it doesn’t rain, the forecast is “correct” as it also means there’s a 70% chance it will not rain! Remember to learn what the forecast is really about in this week.
