New Week, Same Results. Yet, Changes Are Looming

We all know it, Texas get hot and stays hot for quite a while. Even the beginning of October can sizzle. In fact, record high temperatures top off in the 90s all though out October. That's great and all, but we would like a reprieve from the heat now. Its September, meteorological Autumn began and football season is here. Good news, a break is near, but we still have to wait a little bit longer.

In the middle and upper levels of the troposphere, high pressure remains in the picture circulating hot air all around us.


Remember: Under domes of high pressure, the air sinks, dries, and heats. In other words, it is tough for clouds to develop, and if they do, they cant grow tall efficiently to create enough water droplets to fall as precipitation. Additionally, with air sinking, it can heat up quick, which is the key reason for above average temperatures.

High pressure will stay still for most of this week, before making a move as a cold front slides down from the north later this week and into the weekend.


 
Within the above forecast image, you will notice two features. One, Tropical Storm Leslie in the Atlantic Ocean, which is poised to move over Bermuda. Two, is a sting of green over the Lone Star State. That string of green is the model putting out precipitation Saturday afternoon. Yes, this means that at this time, rain could be in the forecast for the A&M and Florida game this weekend at Kyle Field. I will keep you updated all week if there are any changes to the forecast.
 
Not only will this area receive some much needed rain, but behind a cold front, cooler and LESS HUMID air will spread all across the area.
 
 
The above image is the forecast panel for Sunday, post cold front at jet stream level. Winds 35,000 feet above the surface have turned from the north drilling in the comfy air mass. Despite a few storms to dance around early in the weekend, it will be worth it to finally add a touch of Autumn here.
