In the wake of Friday morning's Arctic cold front, the Brazos Valley will be stuck well below normal -- temperature-wise -- through the weekend of November 23rd & 24th.
Stuck in the Refrigerator
Temperatures fell into the 40s, Friday morning, for most of the Brazos Valley and will continue to slowly slide through the weekend.
As of Friday night, temperatures for most were holding steady around 39° to 40°. The Brazos Valley is expected to wake up to temperatures right around there by sunrise Saturday morning.
Brisk north winds at 15-20mph, gusting to 25mph at times, and overcast skies will keep temperatures from warming much on Saturday (along with a rain chance -- we'll touch on that below).

Same case hold for Sunday. While there should be a break in soggy conditions, overnight temperatures are expected to reach the mid 30s and then struggle to make the mid 40s by late afternoon.
Add Insult to Injury -- Rain Chance Continues
While the rain is still needed across the Brazos Valley -- it comes at a very unseasonably cold time for the area. As of Midnight Friday, College Station was only officially 0.16" ahead on rainfall for 2013.
An upper level weather maker was located over Southern California Friday evening. That will send a few disturbances through the jet stream, towards Texas, over the weekend.
By Monday, that low pressure system will be in the western portion of the state bringing another with it another widespread soaking rain chance. Due to the amount of rain in the forecast, temperatures could have a hard time even making it to 40° by Monday afternoon.
Before we put the cart ahead of the horse -- let's touch on the weekend rain chance:
While rain activity is expect to be off / on Saturday, temperatures will likely remain stagnant as light rain / drizzle is falling in the Brazos Valley. Best chance to see that soggy weather will run between sunrise and noon Saturday. A few widely scattered showers could continue into Saturday afternoon -- but (as mentioned above) we expect to get a brief break from rain between Saturday evening and noon Sunday.
Watch the Forecast Close for Monday Morning
As our upper level system approaches Monday morning, the temperature in the mid to lower atmosphere is expected to drop below freezing. Surface temperatures (our normal air temperature) is expected to be close to freezing from a Brenham to Navasota to Trinity line, and points north.
Forecast Sounding for 12am Monday -- showing temperatures through the atmosphere
Should rain begin again between Sunday evening, overnight, and early Monday morning, it could turn into sleet or freezing rain.
Even though we are sitting in a very cold air mass, ground temperatures will remain above freezing through Monday morning. That said, if precipitation changes over to a winter mix, bridges and overpasses will need to be monitored closely.
The rain chance will only increase through the day on Monday -- however, the freezing rain / sleet chance will be diminishing the further we get from sunrise.
*This is not a 100% guaranteed sleet / freezing rain event. Conditions will need to be monitored closely over the weekend*
