Happy Sunday everybody, if you haven't noticed yet I am going to be using the wind map that I have been posting next to the wind direction under the current conditions section. So if you want to get the full experience out of my posts please look at it before you read any further.
We actually have some interesting weather patterns today, so let's get to it. Notice the rain currently falling over mostly over Missouri, Illinois, and Iowa to the north of the stationary front. I am sure if you looked at the wind map today you noticed the winds northward from the Gulf of Mexico. What is happening is those winds are warm moist and conditionally unstable. In order for precipitation to occur the airmass needs a lifting mechanism which is where the cold airmass comes into play and forces itself underneath the warm moist airmass in a process called convective lifting.
So what does this mean for us? Well essentially that warm front is going to take over the cold front and begin moving in a northerly direction and as the low pressure system over New Mexico dies out a cold front from the Rockies will move across the Great Plains. These conditions are what will cause the formation of a mid-latitude cyclone. Guess what it is headed for the upper Midwest too! So as for tomorrow expect cloudy skies, some rain off and on, and temperatures similar to todays. Once the mid-latitude cyclone develops more the Eau Claire area will likely experience thunderstorms and temperatures in the mid-70's beginning on Tuesday.
