Weather Headlines

–A beautiful Labor Day weekend

–Watching a very dangerous and powerful Hurricane Dorian

Main threats

No weather threats in sight for our weather.

Summary

We’ll see our nice weather continue for the next several days. Toward the end of the forecast period, Dorian should be moving through the Carolinas. That means we stay dry. We should see northerly breezes from the circulation around Dorian, which will give us more dry weather with low humidity. We should also see the western-most edge of Dorian’s clouds, which can make for a beautiful eastern sky.

Records

The remnants of Hurricane Harvey arrived in Tennessee on this day in 2017. Harvey had made landfall near Houston, Texas as a cat 4 storm, then curved north and east to move over portions of western and Middle Tennessee. Nashville recorded wind gusts to nearly 50 mph, as well as a tornado in the Bordeaux area of Nashville.

Tropics

Hurricane Dorian remains a very powerful cat 4 hurricane this morning. In fact, the 7:00 a.m. advisory has Dorian even stronger than it was last night, with winds now of 145 mph. Additional strengthening is possible. A cat 5 hurricane’s winds begin at 157 mph. It is not impossible for Dorian to at least briefly reach cat 5 intensity over the next couple of days.

The track has shifted eastward a bit more, now keeping the center of the storm off the Florida shoreline. Unfortunately, this means even more trouble for the South Carolina coastline, where Dorian could make a direct landfall.

There is still so much uncertainty in the forecast and residents of Florida are strongly urged to continue to prepare for a major hurricane, as changes in the path are still possible. Even if Dorian doesn’t make a direct landfall, the effects from the storm could still be quiet dire for a great many coastal communities.

In other tropical news, we have two other areas to watch. The system in the southern Gulf will move into Mexico. That system over by Africa will have to be watched. Thankfully, we have a lot of time to do that.

Hurricane’s require a water temperature of at least 80 degrees in order to develop and survive. The warmer the water, the more potential the hurricane has of becoming stronger.

Inversion

When temperature is steady or increases with height. Normally, we expect temperatures to decrease with height (that’s why it’s colder on mountain tops).

During an inversion, a layer of warmer air can be found above a layer of cooler air. As long as temperatures decrease with height, air will rise. If, however, there is a warm layer interrupting that process, the air will cease to rise. This inversion traps the air beneath the warm layer, creating higher pollution levels and unhealthy breathing conditions.

In the diagram below, the warmer air is the inversion layer.

NASA Knowledge

Yesterday, the International Space Station flew right over the top of Hurricane Dorian. What a sight that must have been! They sent back pics from their vantage point, 250 miles above the storm.

News

All eyes will be on Dorian today. Evacuations are underway for some coastal communities of Florida. This is certainly a storm to keep an eye on.

I’ll keep you all posted!
