No way around it folks -- we are firmly planted in some of the hottest days of the year. The average high for today is 97°. By the end of August, our "average" daytime high will slide back down to 95°.
Not a huge change or cool down, but its a move in the right direction at least.
We managed to reach 102° for a daytime high in Bryan / College Station this afternoon -- 4° off the record high of 106° set back in 1951. Factor in a heat index and it felt as hot as that record high.
We'll continue to dial up the heat for the next several afternoons. High pressure is in firm control of the atmosphere which means that the hot / dry conditions are in the crystal ball for all of Texas.
Here's the rundown as of tonight's forecast:
Factor in a heat index -- mid-to-late afternoon hours will feel more like 105° - 108°
Notice we didn't put Saturday or Sunday into that list? That's because there's a good chance we'll be able to bring afternoon highs back into the double digits for the weekend. An increase in tropical moisture should add more cloud cover to our sky, along with the off chance that a few widely scattered showers / thunderstorms could pop up during the afternoon hours. More on that in later blogs this week, but for now we'll call it a 20% chance over the weekend.
Heat Advisories for Some
Below is a look at current HEAT ADVISORIES in the Brazos Valley and across Texas:
Here's the question -- if we're all expecting a "feels like" temperature to run between 105° and 108°, why are only a handful of us under the advisory? The answer is this: It depends which county you are in and which County Watch Area (CWA) for the National Weather Service that lies in.
For our forecasting purposes we monitor the counties you see each day on-air. That said, Milam, Robertson & Leon Counties are watched over by the Dallas / Fort Worth National Weather Service office. Lee County is under the Austin / San Antonio office. The rest of the Brazos Valley is under the Houston office (including Brazos County / Bryan / College Station). If a warning / watch / advisory is going to be issued for your county, it will come out of the National Weather Service office that corresponds with the CWA you live in.
For each office, their criteria for certain Advisories / Watches / Warnings are different -- Heat Advisory included.
For the Houston National Weather Service, a heat advisory is issued when:
For the Dallas / Fort Worth National Weather Service, a heat advisory is issued when:
Regardless of being in a heat advisory or not -- triple digit temperatures and higher heat index values are nothing to mess with. Take caution all around -- and just think, cooler months are just around the corner.
