An unsettled pattern

Forecast_Template1

Main threats:

No widespread hazardous weather is expected, though any isolated storm could become strong, with small hail, frequent lightning, heavy rainfall, and gusty winds.

Summary

Many of us stayed dry on Father’s Day, but some of you didn’t. Yesterday’s storm coverage was about 30% and today’s should be about 50%. Keep in mind that severe storms are not expected, but (like yesterday) any storm that pops up in this heat and humidity will always have the potential to produce frequent lightning, small hail, gusty winds, and heavy rainfall. Just be aware of that through this week.

The better day of the week looks to be Friday, at this point. After that, we return to a summer-like pattern, with isolated afternoon heat-of-the-day type storms for our weekend.

WeatherTAP WeatherFACT

The moon was amazing last night! It becomes a Full Moon tonight. I figured I’d give you some moon facts today. First of all, the moon has gravity, though it is 1/6th that of earth’s. Still, objects will fall to the ground when dropped on the moon, rather than float away.

Since the moon doesn’t have air around it, the temperatures can swing quite wildly. Afternoon highs can reach 260 degrees, while overnight lows can drop to -280.

Interestingly, we now know there is water on the moon…and lots of it! It’s trapped beneath the soil and in ice on the moon’s poles. Can you imagine drinking moon water?

Records

On this date in 1882 a tornado traveled 200 miles across the state of Iowa. The tornado hit the town of Grinnel at sunset, killing 60 people. The tornado, traveling at 60 mph, arrived in Mount Pleasant at around 11:00 pm, causing extensive/catastrophic damage. Can you imagine tracking a tornado from sunset to nearly midnight?

One week from today I’ll be participating in the NASA Social event for the launch of Falcon Heavy!!!! We’ll be doing NASA-led tours of facilities, interviewing, etc. This will all lead up the launch at 10:30 CDT. I’m trying not to think about it too much…… trying……

Sunday Story: Summer’s heat no match for the mountain

We are so fortunate to be able to call this Cumberland Plateau our home. The scenery is beautiful and our summers are rather pleasant, especially compared to the rest of the state.

Our average dates of hitting 90 degrees for the first and last time within a summer season on the plateau is July 8 and August 16, respectively. Those dates are May 27 and September 15 for Nashville. The latest Nashville has ever gone without hitting 90 degrees in summer was July 5, 1893.

There have been several summers, since record keeping began, in which the plateau never saw a single 90-degree temperature reading. The least 90-degree days Nashville has had is 11 and that was way back in 1889. Again, Nashville has hit 90 degrees at least once in every single summer since records have been kept.

The most 90-degree days we have ever had on the plateau is 45 back in 1954. In that same year, the city of Nashville recorded 96 days of 90-degree heat! That’s more than twice what we had here on the plateau.

The earliest we have ever hit 90 degrees on the plateau was on May 13, 1962. The earliest for Nashville was April 9, 2011. That’s more than a month earlier than us.

The latest we have ever recorded a 90-degree day was September 22, 1980. Nashville has seen 90-degree weather as last as October 19 (2016).

The summer of 2007 was one of the hottest on record for the plateau. That was when we hit 90 degrees or better for 19 days in a row. You think that was bad? Nashville hit 90+ degrees for 34 straight days that summer.

So, while our summers may get quite warm here on the plateau, just be glad you’re up here on this mountain!
