Colder Air Coming Down The Pike

For a change, it was quite welcoming to hear the pitter patter of rain and the percussion of thunder. Parts of the Brazos Valley are in a severe drought with barely 0.50" of rainfall accumulation since October 17th. We need more, and its always good to see liquid gold in moderation. Too much in too little time could cause problems. But an rain is good rain around these parts.

Nonetheless, the extreme December heat has been wiped away via a cold front that delivered a small heap of rain this morning. This past weekend, there were several locations in Robertson County that clocked temperatures near 90°! As drier, cooler air filters in, expect Wednesday to be a gem with a mostly sunny sky, morning lows in the upper 40s and daytime highs in the low 70s. However, the heat and humidity will build again later this week and towards the weekend.

Yet, there will be a huge temperature swing on the horizon.

The key reason why today's front will not give us the polar plunge is due to its origins. We call these "Pacific Fronts" that originate off the.....(you guessed it) Pacific Ocean. Typically, these fronts will cool us down marginally and supply a quick shot of drier air. Note the temperatures behind the front into the Rockies and Pacific Northwest really are not that cold for this time of year. On the other hand, there will be another storm that will drill in air from Canada over the coming weekend.

The air way up into Canada has been hiding for a while, but now its going to come out and play a game of peek-a-boo. Sure enough we will say, "I see you." We will not even come close to see temperatures in the 10s and 0s here, but when this pool of polar air dives south it will moderate the air that we currently have in place.

Computer information shows that we will get hit with the cold stuff in a period between Sunday and Monday as the jet stream will move our way.

When you see a dip in the jet stream like that, you should be aware that changes are coming. Not only will this cool the Brazos Valley off in a big way, but also well needed rainfall will accompany the onset of the new air mass.

At the moment, what I can foresee are high temperatures by next week could hold in the 50s with a few evenings in the 30s/20s.

I will keep you updated with the latest.
