Hope you enjoyed the pictures yesterday. I thoroughly enjoyed my accurate prediction of weather conditions for today. I mentioned that the cirrus clouds yesterday along with the wind direction would likely cause rain today. Let's take a look and see what is in store for tonight in the thunderstorm department.

Daily Barometer Graph

The barometric pressure graph above shows values over the course of the last 24 hours. As you see barometric pressure rose steadily throughout the day yesterday, which is associated with the high pressure system I talked about yesterday. As of around 9:15 a.m. this morning barometric pressure began to fall causing an increase in cloud cover and wind speed.

Surface Data - US Current

I know this surface is busy but I want to use this one convey to what the low pressure system is doing currently and will do later tonight. As you can see that low pressure system is presently centered over South Dakota with a barometric pressure reading. Remember back to previous posts, low pressure systems move in a counter clockwise orientation, thus sucking air north on the eastern edge of the system. This exactly what is causing the warm front extending down through Iowa and Illinois. Keeping this fresh in your mind look at the next surface map below.

US: Current Weather

What I want you to take out of this map is the high pressure system centered over Saskatchewan, Canada. I have mentioned before high pressure systems move in a clockwise motion pushing air outward. What is happening where the two pressure systems are converging? If you answered you're right, and that is exactly what will happen in Eau Claire around 11pm tonight. As for tomorrow we could see a continuation of rain and slightly warmer temperatures than today.
