Yucky Humidity For Now, But Cold Air Nears

No matter what your outdoor plans were this weekend, the weather was sensational all across the state. Here in Aggieland, a multitude of events had superior turn outs due to Mother Nature's grand presence. Not only did Johnny Football soar during the Maroon & White Game, the temperatures did as well. Additionally, if you went out to Kyle Field Sunday evening for Film on The Field, you were treated to perfection.

Now, as we began the new work week, you might have noticed the enhanced cloud cover and additional humidity in the air. Additionally, we are battling a pressure gradient between high pressure to our east and a broad low pressure circulation over the Rockies. This "pressure gradient" is kicking up the wind speeds from the south this week. However, once we see a cold front trailing a center of low pressure to our north, the wind will come from a much colder direction.

As of this afternoon, many areas of the Rockies are experiencing light snowfall with the heaviest concentration of heavier snow around northern Colorado.
 
 
Despite the disorganized look of this picture, this broad area of low pressure will hook up with energy in the upper levels to spin up a stronger storm that will generate a storm that will affect most of the lower 48.
 
The following image is a prog of the 500mb level from a weather computer model illustrating where the upper level energy exists that will help amplify this storm.
 
 
The main spoke of energy is highlighted in yellow and orange with an "X" from northern California to the eastern Pacific. Notice how its an elongated feature. By the middle of the week, this feature will move towards the central/southern Plains and concentrate.
 
 
On Thursday, the concentration of upper level energy (spin) will focus to our north and unfold a severe weather outbreak that will span from central Texas towards Iowa. Additionally, its going to be cold enough that heavy snow will fall all over the Rockies and up into the Dakotas.
 
 
Here in the Brazos Valley, Thursday will be the main day where changes occur for us. A cold front will approach us from the parent storm and produce a few thunderstorms during the afternoon hours. A few of these storms could be severe, but the best chance of severe weather will be to our north and east. Once the front moves though Thursday afternoon/evening, the wind will switch from the northwest, shuttling in much lower humidity and much colder air. By Friday, high temperatures will reach the middle 60s, where overnight lows will bottom out in the 40s and 30s!!!!!
