Prolonged Chill

The weekend produced a big change in the weather across the entire Brazos Valley. A cold front came though and that opened up the gates to Canadian Chill. We went from the 70s Saturday, to highs in the mid 40s today. Additionally, clouds showers, and gusty winds have created a bleak scene outside. Good news is that this pattern will break....eventually.

Take a look at the following image....
This is a radar and satellite composition with a jet stream. The reason for showing the jet stream on this graphics is to illustrate how the winds in the upper levels are acting. Upper level winds are a vital part of forecasting because this shows us the path for storms. Note how the jet stream has a large dip that falls down to Texas and Northern Mexico. Because of this, weather systems will not be able to move quickly as opposed to a jet steam that is flat, or flow directly west to east.

Due to this orientation, the clouds, drizzle and cold air will stay around for another 24 to 36 hours. Therefore we will see a gray sky all the way until Wednesday morning. Eventually, high pressure will have its way and break this force field to rip up the clouds allowing the sun to shine Wednesday afternoon.

Despite the sun around, temperatures will remain in the low 50s due to a wind flow from the north around high pressure.
