The Muggy Weather Returns: A sure sign of spring

Posted: Updated:

"The Muggies", a good sign that spring has really sprung and that summer is not far behind. Its the time of year we see less and less of Canada and more and more of The Gulf of Mexico. The air that comes from down south is not only warmer, but juicier. Its usually the fuel needed to sustain our warm season storms.

The approaching storm system that will bring us a chance of strong storms this week will also pump in warm and moist air ahead of it. The map below is the GFS model output for dewpoints late Thursday. You can see that the gray shaded areas are running from the Gulf to Minnesota. This gray shading is representative of the moist stream coming up from the Gulf fo Mexico. You can also see the greener and browner shades to the west of Minnesota. That is much dryer air coming in behind our mid week storms.

In this part of the country we get spoiled, or punished, depending on how you look at it. We stay dry most of the time, but we do see are share of humid days. Below is a graph of how it feels depending on the dewpoint temperatures. As you can see we are just creeping into the 60° range, so the comfort level is not going to be too bad, but we will still notice that it is a bit more muggy come mid-week.

When it comes to the sultry conditions, we are just getting started. Our muggies peak in mid July before we start getting more shots of cooler and dryer air from Canada.

This of course ushers in Fall, then Winter, but we won't talk about that just now.
