OMG!!! The weekend was soooo nice and has through today....but.....it's WI...soooo you never know what's around the corner

It's sure been warming up outside!! YIPPY!! Today's high is expected to reach 75F. The current temperature is at 70F and feels like 70F. Humidity is at 66%, with a dew point of 57F. The barometric pressure is at 29.51in. Well seems like a pretty nice day...right?  Well, looking at the barometric pressure we can see that's it's down in the 29's which indicates low pressure moving in, and as we know low pressure indicates stormy conditions.

Looking at the surface map we can see a low pressure system located in northern MN with a cold front moving in throught the center of MN. Also, looking at the wind map below the surface map we can see winds are moving into WI from the S. By looking at both of these we know we have precipitation moving in. This is because a cold front has cold air coming in from behind and warm air in front of it. We already know this will cause the warm air to rise and condense, creating precipitation of some sort. However, seeing that wind is coming in from the S, with some strenght might I add, we also know there is a lot of moisture being fed to the N. The two of these combined will create wet conditions for our region today.

Looking at the water vapor map below we can see where all of this moisture is located. By comparing the cold front line in the surface map with this map we can what is known as the squall line. This is the line where the moisture is located in relation to the cold front.

When looking at the jet stream map below we can also see how these conditions are being fed. We can see a trough located in the northwestern portion of the states. This bringing in cold air from the north. The rest of the states are being fed warm jet stream air from the tropics. These two components are contributing the the difference in wind temperature, which is playing a role in the precipipation and temperature conditions.

As we just stated the jet stream conditions, as well as the wind directions conditions are all playing a role in the severe temperature gradient we are seeing below. Notice that the change in temperature is taking place where the two jet streams are meeting, the cold front is located, and the wind directions are colliding. It's not a coincident...this is how it all works together.  

The rest of the afternoon is forecasted to be a windy day with early showers and scattered thunderstorms in the afternoon. Later today winds will shift the SW leaving the evening with overcast conditions and rain showers.

By tomorrow all our nice weather is forecasted to go down the drain. Tomorrow's high is only forecasted for 45F with winds coming from the N and an 80% chance of rainshowers. BOOOOO!!!!
