Here's something we don't discuss everyday. The vital role of what is called a forecast sounding when we are putting a weather forecast together.
So each particular model we look at has it's own set of data. And that data provides us with a vertical profile of the atmosphere which gives us an idea on what is happening in the low, mid, and upper-levels. Plotted with height is the temperature (red line) and dew point temperature (green line).
Given is a what the forecast soundings looked like for today and Thursday. What you'll notice is that there is quite a bit atmospheric moisture in the low-levels and how you can tell that is by how close the temperature and dew point temperature lines are. That portion of the forecast sounding is "saturated".
Moving up the vertical profile, you'll see that the lines are more spaced out. That means we have a lot more dry air in the mid and upper-levels.
What does this entail? Well, the moisture in the low-levels means we're in for cloudy, gloomy skies today, tonight, and for good chunk of tomorrow.
It does look like some dry air works into the region late Thursday afternoon into Thursday evening. This may result in some clearing ahead of a storm system that will track well to the Stateline's south. Highs will remain in the 40s today, but then make the climb back into the 50s Thursday and Friday.
