Think back to one year ago today. Really give it some thought. Do you remember what you were doing?
One year ago today, I was sitting in Waco, Texas with fellow broadcast meteorologists, National Weather Service meteorologists and emergency managers from counties across Central Texas, talking about how we could all work together in order to give a more precise and clear message to the public when it comes to severe weather. Later, I'd come back and do the 6pm & 10pm newscasts from our "temporary" set in the KBTX News Room while our studio was undergoing an upgrade. Remember that big t.v. monitor we used to stand in front of for about a month or so?
That's what was happening inside -- outside we were sweating it out as Bryan / College Station hit a new afternoon high of 106°. In fact, most of Texas was boiling that afternoon. Keep that stat in mind as we start talking about the forecast for today and heading into the weekend.
Triple Digits Make Their 2013 Appearance
Looks like we've held off for about as long as we could. Widespread 100° temperatures look to take over the forecast for the last half of this week and the weekend. Sure a few of us (*cough *cough Brenham) have already seen 100° this year, but it looks like a majority of the area will make it there sooner rather than later.
The first half of this week brought a "zonal flow" in the atmosphere across the United States. Basically, the jet stream has run west to east, almost flat across the center of the country. The jet stream is what carries weather systems our way, so with it locked up to the north, we've seen quiet and hot weather in the Brazos Valley.
Under that zonal flow, high pressure started to develop over West Texas Tuesday afternoon. Today, that high will continue to amplify and anchor over far West Texas, New Mexico and Arizona. Give it another day, and we'll have a massive high pressure ridge over a majority of the Western US, centered on the Desert Southwest / Four Corners region.
Even though that high pressure isn't sitting right over the Lone Star State, we'll look for it to dominate our weather pattern, keep things hot and dry, and shove those afternoon highs into the triple digits. A handful of us should find that today, while others may have one more day and hold off until Thursday.
Here's a look at what is expected in Texas then next few afternoons:
With a record high being set last year, it got me thinking about others that we have coming up in this stretch of expected 100s. We may come close to a few of these over the next couple of days.
Any Relief in Sight?
Due to this high pressure stretching all the way into Southern Canada, the jet stream will bend and dive south over the Eastern US by the end of the weekend.
This will allow for a weak cold front ("cold" being a stretch of the word) to reach South and Southeast Texas. The important thing, at least in my mind, with this "front" is the slight chance for showers and thunderstorms it will bring (for now only a 20% chance). Rain is something we really haven't found in a few weeks and would be a welcome sight to lawns & vegetation that are starting to become stressed.
The "front" will also help drop afternoon temperatures out of the triple digits and back into the mid-to-upper 90s. Not a big drop -- but still a cold front to kick start July isn't a bad thing!
More details on that rain chance and "drop" temperatures as we start to round our way into the weekend...
