After a week of rain, then days of chill, and even a few nights below freezing, Minnesota is due for a change. A peek ahead at the forecast models is shedding more sunlight on our gloomy situation.
The main component in the overall scheme of things is the position of the Jetstream. Unfortunately, the jet stream on this Wednesday is not in a good position to provide much heat. As we know, the jet is a river of air aloft that separates the colder air to the north from the warmer air to the south. If you want to be warm, then you need the jet to the north, but as you can see on the 300 mb weather chart below, the jet, outlined in red, is sagging south for a large part of the Upper Midwest.
Now, here is a look at the Jetstream position for early next week. While it is still slightly to our south, it is much further to the north, which brings that warmer air closer to us.
Now, the Temperatures for the week ahead will follow the jet and warm up for us here in the Upper Midwest. Below is a look at the forecast model temperatures for early next week. Take a close look at the orange and reddish colors, those are 70s my friend.
This weekend is looking to be one of the nicest in weeks. Not only will be see temperatures rise back to normal, but we will have plenty of sunshine as well. The 700 mb relative humidity chart is great for detecting the moisture aloft, the moisture needed for clouds. As you can see in the picture below, Saturday is looking dry and sunny.
Now that we are getting farther into May, the average highs are getting warmer and warmer. So now when we say temps near normal, for this week that means upper 60s to near 70°.
