Meteorologist Mark’s 5-Day Wx Concerns

At this time, this looks like a “low-end” threat, but I’ll keep a close eye on this in the coming days.

Meteorologist Mark’s Wx Discussion

Thursday is looking more concerning for the Southeast, especially for Mississippi and Alabama. Like the last threat, will it all stay to our south? That is a good question. It certainly bears watching. The Storm Prediction Center has already highlighted Mississippi and Alabama for a threat for severe storms, including tornadoes. As it looks right now, should that threat develop farther north, our main threat would likely be straight-line winds. Again, I’ll keep a close eye on this in the coming days and keep you posted. For now, just keep this in mind when making plans for Thursday.

On This Day in Wx History

1968- An unusual late-season snowstorm strikes the mid state, as Murfreesboro receives its greatest one-day snowfall ever, measuring 10″, as does Lebanon, with 9″.


Solar/Lunar Data 

90 Days until Summer!

Yesterday’s National Temperature Extremes

High:  93° at Rio Grande Village, Texas

Low:   -2° at Copper Basin, Idaho 

Today’s National Wx Hazards

Severe thunderstorms will be possible today across portions of the southern plains, especially along the Texas/Oklahoma border. Farther north and west, in the colder air, snow will fall across the Rockies. Some of that could be heavy in isolated locations. A wildfire danger continues for extreme western Texas and southern New Mexico and southern Arizona.

Tomorrow’s National Wx Hazards

Heavy rainfall will be possible along the northern Gulf Coast, posing a flooding threat for the southeast Louisiana coastline and the entire Mississippi coastline. A wildfire danger persists for southern New Mexico and extreme western Texas, while snow continues for much of the Rockies, especially along the Colorado/New Mexico border.

Drought Monitor

The drought monitor is updated each Thursday.

NASA Nerdology 

With so much serious work to do so often, astronauts like to kick back and have some fun now and then. In the picture below, the Expedition 16 crew (the 16th crew of the International Space Station) are seen posing for a fun picture in 2007. The Expedition 16 crew conducted a wide range of experiments in space. On this mission, Peggy Whitson became the 1st female commander of the International Space Station!
