Extreme Cold By The Weekend

Quite and interesting weekend here across the entire Brazos Valley. We have been so used to the cooler and drier air as of late, that the weather this weekend seemed like a big surprise. According to the climate report from Easterwood Airport in College Station, the official high for Sunday was recorded as 84°, just shy of the daily record of 85° set back in 1921. Besides the heat, it was HUMID....yuk!!!  Since, a cold front came by Monday afternoon, which will spill in cooler and drier air.

Overall, it looks like this week should be fairly quiet. Clouds will come back towards the end of the week, as well as additional warmth and moisture. Plus, several showers will be around from time to time on Wednesday and Thursday.

THEN COMES THE BIG SHOW!!!!!!

A pool of Arctic air, building in the northern reaches of Canada will move down into the United States and unleash its fury.

By Friday, a strong cold front will move across the state of Texas cropping up rain and a few thunderstorms on the front side, where the back side of the front will have much COLDER AIR.

Notice in the following diagram that there is a body of high pressure ("H") over southern Saskatchewan, Canada, with a forecasted pressure near 1053 millibars.

This is the GFS's (Global Forecast Systems) simulation of the weather for midnight Saturday. When you add in very cold Canadian air and the potential of a very strong high pressure center to deliver this cold air, this tell me a couple of things.

1) The cold air can move this far south.
2) Yes, the temperatures will moderate, but will still hold its core.

In other words, this weekends weather will make you shiver.

Furthermore, look at the temperature anomalies compared to average with this arctic outbreak.

We are looking at temperatures that will probably be around 10°-13°C (18°-24°F) below the climatological average for this time of the year. Therefore, high temperatures may only approach the middle 40s, with overnight lows in the 30s. Yeah....it cold be that cold around here. But here is the twist.

Typically in our part of Texas, a cold air mass will swing in for a day or two, then the temperatures climb pretty quickly, but this is not the case for this event coming up. Its seems like the cold air could stick around for a longer period of time. Maybe 4-5 days, if not longer, beginning on Saturday.

On top of all of this cold news, snow could fly in parts of the panhandle and west Texas as well for the first time this season.

The forecast can change, but use this information as a heads up that a big change is headed our way this weekend.
