Pleasant Weekend!

* Today was just a spectacular day weatherwise. Our high temperature was 71 in Meridian with a very light breeze. Dewpoints are very low so it feels quite gorgeous. Have you ever wondered why the sky is so blue in fall and winter? It actually has to do with drier weather. As light radiates into our atmosphere, the majority of the visible light (radiation in the visible spectrum) is allowed through the atmosphere. Some radiation that has the wavelength of blue is scattered, giving the sky a blue tone. However, when more moisture is present, more light is diffused. If you've ever taken a physics class you know that when you mix all different wavelengths in the visible spectrum, you get white. And sure enough, on those hot, humid July afternoons our sky appears more of a milky white rather than the crisp blue color we saw today! Pretty neat stuff!

* An upper level low looks to make its way across the deep south on Tuesday. This would create the required lift we need to generate some showers and thunderstorms and get us the much needed rain we've been asking for. The problem lies into the point just above....we have very low moisture content in the atmosphere. Our computer model guidance is still flipping between opening up the Gulf of Mexico or keeping us with a dry flow...so that will be the main factor in precipitation chances for Tues and Weds. Lets keep our fingers crossed!!
