Thursday Weather Talk

Happy Thursday afternoon! 

Have you noticed how warm it is outside? It is pretty typical for this time of year and with a ridge of subtropical high pressure across West Texas slowly inches its way northward, we will see that easterly flow begin to increase the chances of showers across the Coastal Bend on Friday. As I am putting this together here just before 2:00 pm, there are a few light showers building their way up offshore on radar about 50 miles offshore Port Mansfield, moving to the northwest, but nothing of any real significance to discuss on that at the moment. 

Temperatures remain steady across the local area right in line with the normals for this time of year in the mid-90s. I do expect the chance of showers to increase over Friday especially along the sea breeze before towards the mid to late afternoon hours. Nothing severe to discuss with them and they should pretty much remain of the garden variety type that we generally keep in the forecast this time of year. 

WHAT IS A SEA BREEZE? 

You hear us weather folks talk a lot about the “sea breeze” and one of the biggest questions that we get asked is what is it? The real short answer is that is the flow of air from sea towards the shore during the daylight hours. It is actually a bit more complex than that, but for now we will just try and keep it simple.

Have you ever noticed that we here in town often enjoy cooler temperatures during the day than the folks out near Hebronville or Three Rivers? Part of that is because of the sea breeze. It generally makes daytime temperatures a little bit cooler in areas located 20 miles or so from the shoreline. Sea Breeze is cooler and as it mixes with the warmer air onshore, you tend to see an upward motion. That is how we end up with so-called “sea breeze showers.”

It takes three main ingredients to make a thunderstorm: 

  1. Moisture 
  2. Lift 
  3. Instability 

As the cooler sea breezes intermix with the warm, often humid air over land you end up with two of those ingredients right off the bat, right? But then as the science works, the warm and cool air mixes over land creating lift and there you have it the ingredients for thunderstorms along the sea breeze near the coast. That is the short answer to a complicated scientific process, but now you get the idea! 

TROPICS

So far the tropics are nice and quiet again and nothing of any real significance to speak of at the moment but as we go into the peak part of hurricane season, we cannot let our guard down. There are some indications that we might see some tropical development later on in the month but that is very far out in the grand scheme of things, but certainly something to keep an eye out for down the road.

NOAA revised their hurricane forecast today and they increased the number of named storms to 19-25 with 7-11 becoming hurricanes and 3-6 becoming major hurricanes. That is on top of the near record pace 9 that we have already seen so far. We will just have to keep our guard up an make sure that we are prepared. 

Tomorrow we can dive into a quick preparedness review for you and your family to help keep you safe. 

Stay tuned for your daily climate data later on and we will keep you informed of things from our perspective! 

Stay Safe!
