Record temperature set in Dayton

Published: Friday, May 19, 2017 @ 2:47 AM

A record for the warmest low temperature was set in Dayton on Thursday.


Thursday’s low temperature of 69 degrees was a new record, breaking the previous low record of 66 degrees set in 1969.

Temperatures are expected to be back in the low 80s Saturday.

Showers, storms return today, warmer for weekend

Published: Wednesday, May 24, 2017 @ 5:15 AM

Today there is a low threat for severe weather, but if conditions come together we could see one or two storms strengthening quickly, said Storm Center 7 Meteorologist McCall Vrydaghs.


  • Showers and storms develop this afternoon
  • Isolated strong storm possible
  • Damaging winds or weak spin-up tornado possible

TODAY: While there is a good possibility that severe weather may not occur there is a greater concern if any strong storms do form, they could produce isolated damaging winds and the possibility of a weak spin-up tornado. If a severe thunderstorm warning is issued in your area, it should be taken seriously.

Mostly cloudy skies and mild this afternoon before scattered showers and storms develop. Temperatures climb into the upper 60s and feel a bit more humid. As an area of low pressure approaches from the south, showers and storms will begin to blossom.

Any sun that breaks out before the storms will increase the threat for severe weather. The coverage will be widely scattered, and each storm will have to be monitored to see how they form. Generally counties south of Interstate 70 are in the best position to see stronger storms, but everyone will have the potential to see isolated storms with heavy rain and gusty winds.

TONIGHT: Mostly cloudy with a few passing showers still possible. Lows in the upper 50s.

THURSDAY: Clouds linger with a few passing showers possible at any point during the day. Cooler with highs in the middle 60s. Drying out into the evening.

FRIDAY: Quiet and dry for the first half of the day. Temperatures climb to the middle 70s. Some sunshine with clouds increasing. A few showers and maybe a little thunder pass through at night in the southern Miami Valley area.

SATURDAY: Some dry time early. A boundary sets up that will trigger showers and storms during the afternoon. Activity will be scattered, but we could see an isolated strong storm. Highs climb to 80 with dew points in the 60s, so it will feel warm and muggy. More showers overnight.

SUNDAY: Some showers and storms around for the first half of the day. Towards late afternoon and evening some will get back to some dry time. Highs around 80 and still a little muggy.

Barrier discovered circling planet created by man-made radio waves

Published: Monday, May 22, 2017 @ 4:58 PM

            The Van Allen radiation belts are two donuts of seething gas around the earth. They have been found to contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching earth. A cloud of cold, charged gas around earth, called the plasmasphere and seen here in purple, interacts with the particles in the earth’s radiation belts shown in grey to create an impenetrable barrier that blocks the fastest electrons from moving in closer to our planet.

I used to watch a science fiction show on TV called Amazing Stories while growing up back in the mid- to late-1980s.

The show was created by Steven Spielberg.

I still remember an episode called “Fine Tuning” where a student was working on creating a souped-up television antenna so that he could pick up signals form half a world away. While he and his buddies were messing with the antenna, they accidentally crossed wires and after a lot of sparks, they started picking up a television signal from another far-away planet. The funny part of this was that the signal they received was an alien version of “I Love Lucy.” The aliens had apparently been watching television broadcasts being transmitted from earth and mocking them.

So why am I telling you this story? Because of a recent, amazing discovery from NASA.

No, NASA has not picked up a television signal from another world, but they have found that radio waves from Earth have created a barrier around our planet. This human-made barrier, which was detected by NASA’s Van Allen probes, was created by the interaction between man-made very low frequency (VLF) radio waves and charged particles in space.

VLF signals are transmitted from ground stations at huge powers to communicate with submarines deep in the ocean. While these waves are intended for communications below the surface, they also extend out beyond our atmosphere, shrouding Earth in a VLF bubble. This bubble is even seen by spacecraft high above Earth’s surface, such as NASA’s Van Allen Probes, which study electrons and ions in the near-Earth environment. The VLF radio waves have been found to interact with particles in space, affecting how and where they move.

NASA says this interplay can, when conditions are right, create a de facto barrier that can block high energy particle radiation from hitting the Earth coming from the sun in a solar storm. The probes also noticed an interesting coincidence — the outward extent of the VLF bubble corresponds almost exactly to the inner edge of the Van Allen radiation belts, a layer of charged particles held in place by Earth’s magnetic fields.


So what does all this mean?

Well, now that scientists have figured this out, NASA says it intends to test the shield by intentionally blasting VLF radio waves into the upper atmosphere to see if they can purposefully manipulate the field. If they can, the human-created barrier could theoretically be strengthened to better protect Earth from solar storms, which can wreak havoc on most modern technology.

So, while we still haven’t detected any communications from another planet (that we know of), you must admit it is fascinating how radio waves we use to communicate in the depths of the ocean are reaching into space and may be protecting our planet from harmful radiation. That would certainly be an amazing story! And who knows, maybe those radio signals will be detected by someone listening from another planet?
