My normal Wednesday night blog got bumped by a day, thanks to a busy afternoon / evening of tracking thunderstorms through the Brazos Valley yesterday. Those storms sure did drop a good deal of rain for some -- in fact, parts of Robertson & Leon Counties received between 3" and 4" of rainfall. Some of us missed out completely aka a feast or famine type of day.
Life Behind an August Cold Front
As we sit and talk this evening, drier air is working into the far Northeastern Brazos Valley. Dew points are on their way to dropping into the 60s overnight and then eventually the upper 50s by the weekend! Drier air means that overnight lows can drop a bit more than the normal. The morning temperatures we have lined out for you might even put you in a fall-ish mood.
Here's a look at where we expect temperatures to be first thing Friday morning (7am).
That's the start of a string of mornings with lows in the upper 60s to low 70s. Every up comes with a down, though -- dry air cools off quickly, but it also warms up just as fast. Sunny skies will help bring afternoon highs into the mid / upper 90s by each weekend afternoon. The humidity will be low, so it'll be more of a "dry heat" for us.
It'll be a fight between a disturbance and drier air on Friday.
We have a north to northwest flow setting up over the Brazos Valley heading into the weekend. That flow could bring a disturbance rolling through the Brazos Valley tomorrow afternoon. It's not uncommon for small ripples in the atmosphere to be missed by computer models when this kind of flow is present. That said, some of our computer models are picking up on another chance to see a few scattered showers and possibly isolated thunderstorms Friday afternoon. Overall, we'll leave a 20% chance of rain in the forecast for tomorrow.
Tropical Wave #92L
Talk about your mess over the Yucatan this evening.
A broad area of low pressure along with disorganized clouds and heavy rain are sitting at the mouth of the Gulf of Mexico, moving northward out of the Caribbean.
Computer models have been all over the place with the movement and evolution of this system -- as expected. Typically, it's not until a tropical system gets a clear center of circulation that our computers can start to really get an idea of what will happen with it. The latest plot is below (each line represents a different computer's thoughts on where this system will head).
With a trough of low pressure digging down the eastern side of the country and a northerly flow over Texas, it's our current thinking that this system's moisture will get scooped up and head east of the area. With this in mind, soaking rains should be headed towards places like Mississippi, Alabama and the Florida Panhandle.
All of this could change -- but for now, look for a low humidity & sunny weekend ahead. We'll update you should the script flip and things change.
