High pressure is parked to the east of us and returning a south flow on the back side, aiding warmer air to come back to the Brazos Valley. Plus, the jet stream retreated back to the northern Plains, which means that no big weather systems will impact us for a while. However, computer models are indicating that a huge cold front will form to our northwest and swing through the lower 48 by the weekend.
The following image illustrates the position of the front late Friday:
Cold air will begin to gather and make a move towards the central Plains and the east coast. If you take a look at the cold front, there are triangles at the leading edge of the cold air. These triangles are also called, "pips" and show the direction of the colder air. Note that the directions is towards the southeast, yup that means us and the rest of the lower 48.
During New Years Day, the front will swing though the Lone Star State and move east as well:
At the moment, we will see a change from highs in the 70s to highs in the 50s next week. Additionally, the upper level wind field shows that the core of the cold air will shift to the Great Lakes, Mid-Atlantic, as well as the Northeast. We should miss the coldest of the air, but we will still feel a difference. Yesterday, models were indicating that we could feel a much colder punch of cold air, with highs only in the 40s next week. Now with the latest runs, we should miss the coldest of the air.
This will be a definite shift in air-masses and as the newest computer models come in, I will adjust the temperatures accordingly. Stay tuned for the latest.
