Double Duty Of Weather Danger Today

From Jude Redfield...

    DANGEROUS HEAT & HUMIDITY EXPECTED TODAY!!! I could even argue the moisture content will be higher today than the previous days during this heat wave. Our heat index ends up in the 105 ballpark this afternoon. Treat today as if a heat advisory is in effect. 

    Danger number two comes from afternoon/evening storms.


    Locally heavy rain will pour out of any storm the next few days. Storms don't have to be severe to produce quick bouts of flash flooding. Any storm that develops is capable of dropping 1"-3" in an hour.

    Spotty severe storms are possible today through the weekend. This is pretty common this time of the year with damaging straight-line wind the main threat.


    Future radar is locked on with storm development just after the midday time frame. Storms will be most numerous on the radar between 1pm - 9pm.



    Jeremy Kappell will update the forecast on WDRB News starting at 11:30am -Jude-


A Steamy and then Stormy Monday!

Following a scorching hot weekend which featured consecutive 95 degree highs and triple digit heat indices, the arrival of a slow moving cold looks to bring some relief over the next couple days in the form of scattered thunderstorm rains.


Ahead of this front, it remains very muggy and down right sultry to start your Monday.  

Check out these Future Temps/Heat Indices...




With heat indices again over the century mark, cooling storms are expected to erupt during the afternoon first across Southern Indiana and then later pushing south into the Bluegrass State before fizzling during the evening.

Let's time it out with AdanceTrak...






While not a slam dunk for storms tomorrow, there will be healthy rain chances for those areas along and north of the Ohio River.  

Rainfall projection

Overall the storm chance should slowly fade away Monday evening and Monday night before refiring along and South of the Kentucky Parkways on Tuesday.

Rainfall projection2

Some storms could produce locally heavy rainfall and will not doubt help with those fiery temps!  

Expect more heat and more storm chances for the second half of the week. 

Jude will have a full update first thing on WDRB in the Morning.

Iconic Movie Landmark Destroyed by Storms

Say goodbye to a cinematic landmark. 

The famous oak tree from the movie "Shawshank Redemption" has been knocked down due storms with strong winds in Mansfield, Ohio on Friday. If you remember, it was featured in the 1994 award winning flick, when Morgan Freeman's character, Red, retrieves a buried box at the base of the tree. Andy Dufresne, Tim Robbin's character, also proposed to his wife there. The location of the tree has become a tourist location. It had been previously damaged by lightning a few years ago, but only a portion of it was damaged. The rest of tree fell after this second storm.

Heat Intensifies on Sunday... Storms Arrive to Start Workweek!

The heat advisory continues through 8 pm EDT on Sunday.


After a high of 95 today (tying the hottest this season) it looks like we'll continue to bake into the second half of the weekend with temps expecting to reach back into the middle 90's on Sunday with heat indices rising to 105 or perhaps higher at times!  


Be sure to remember those heat safety tips!  


Fortunately though, we are tracking some relief in the form of a slow moving cold front that looks to bring us a good chance for some cooling storms to start the workweek.


Let's time it out with AdvanceTrak...





Storms could refire for parts of the area on Tuesday.  After a lull on Wednesday, more beneficial rains will be possible during the second half of the week!

Rain chances

Great news for lawns, gardens and outdoor goers alike!

Scary Scenes from China Landslide

Torrential rain this week, in China, resulted in widespread flooding and triggered devastating landslides. As of this morning, the death toll stood at 72, but nearly 100 are still missing. 

The flooding has been happening since Monday of this week and has impacted millions of people. Videos are now starting to surface on the internet, showing the widespread destruction. This one below is a compilation of many videos.

NASA Spots Tropical Storm Darby Near Hawaii...

On July 22, NASA-NOAA's Suomi NPP satellite and NASA's RapidScat instrument gathered data on Tropical Storm Darby as it neared Hawaii and triggered warnings.

A Tropical Storm warning is in effect for Hawaii County and a Tropical Storm watch is in effect for Maui County, including the islands of Maui, Molokai, Lanai and Kahoolawe

On July 22 at 00:00 UTC (July 21 at 8 p.m. EDT) the Suomi NPP satellite saw Tropical Storms Darby in the Central Pacific Ocean. To the east of Darby were post-tropical cyclone Estelle, and new tropical storms Georgette and Frank. In the image the bulk of clouds and thunderstorms appeared in the northern quadrant.


On July 22 at 00:00 UTC (July 21 at 8 p.m. EDT) the Suomi NPP satellite saw Tropical Storms Darby (left), Estelle (2nd from left), Estelle (3rd from left) and Frank (far right) in the Central and Eastern Pacific Ocean. Credits: NOAA/NASA Goddard Rapid Response

Forecaster Powell of NOAA's Central Pacific Hurricane Center (CPHC) said, "After decreasing through much of the night, deep convection around Darby has once again flared along the northern quadrant. Exposed low cloud bands across the southern semicircle show a reasonably well organized system, with good outflow to the northeast."

NASA's RapidScat instrument flies aboard the International Space Station and measures Earth's ocean surface wind speed and direction over open waters. On July 22, RapidScat saw sustained along the northern side of Tropical Storm Darby's center as strong as 24 meters per second (53.6 mph/86.4 kph).

RapidScat is an important tool for meteorologists, because it shows forecasters the location of the strongest winds in different quadrants of an area of low pressure area as they are not always equally distributed.  

At 5 a.m. HST (11 a.m. EDT/1500 UTC), the center of Tropical Storm Darby was located near latitude 18.6 north and longitude 149.2 west. That puts the center of Darby about 390 miles (630 km) east of Hilo, Hawaii, and 595 miles (955 km) east-southeast of Honolulu, Hawaii. 

NOAA's CPHC said that Darby was moving toward the west near 12 mph (19 kph) and that motion is expected to continue through Saturday, then become northwesterly Sunday. Maximum sustained winds were near 60 mph (95 km/h) with higher gusts. Little change in strength is forecast through Sunday.

CPHC cautions that interests outside of the watch and warning areas in the Hawaiian Islands should keep informed on the progress of Darby as it may eventually have impacts on all islands through early next week.

See One Year on Earth . . . From 1 Million Miles Away!

On July 20, 2015, NASA released to the world the first image of the sunlit side of Earth captured by the space agency's EPIC camera on NOAA's DSCOVR satellite. The camera has now recorded a full year of life on Earth from its orbit at Lagrange point 1, approximately 1 million miles from Earth, where it is balanced between the gravity of our home planet and the sun.

EPIC takes a new picture every two hours, revealing how the planet would look to human eyes, capturing the ever-changing motion of clouds and weather systems and the fixed features of Earth such as deserts, forests and the distinct blues of different seas. EPIC will allow scientists to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.

The primary objective of DSCOVR, a partnership between NASA, the National Oceanic and Atmospheric Administration  and the U.S. Air Force, is to maintain the nation’s real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of space weather alerts and forecasts from NOAA.

Weekend Humidity Even Higher Than Right Now

From Jude Redfield...

    Still on track for a few storms this afternoon. Not everyone will get wet! Locally heavy bursts of rain and frequent lightning will accompany all storms.  Clouds hold temps back, but the humidity is high!!! Think the humidity is bad now...it looks to be a bit higher this weekend.


Dewpoints in the mid 70s are likely both Saturday and Sunday.


FYI...These kind of dewpoints are few degrees higher than what we have now.


Katie McGraw will have radar updates this aftenoon if you are hoping to dodge the showers and storms -Jude-


What's the Dew Point Got to "DEW" with it?

Question: What's the dew point got to do with it? 

Answer: A lot! 

To gain perspective, since spring, I have used the dew point temperature graphic, during almost every forecast on WDRB News. It's that important! Today's dew points are in the middle to even upper seventies. 

7-21 dew points

But recently I have noticed a lot of people asking, "What does the dew point have to do with the humidity?" 

To answer this, let's start with relative humidity.

It is defined by the National Weather Service as "the amount of atmospheric moisture present relative to the amount that would be present if the air were saturated. Since the latter amount is dependent on temperature, relative humidity is a function of both moisture content and temperature. As such, relative humidity by itself, does not indicate the actual amount of atmospheric moisture present. See dew point." 

In lay man's terms? Because it is taking into account TWO properties, it will not accurately tell us how dry or sticky it is outside. BUT the dew point will. 

For example, in the morning or winter, it is common to see the relative humidity at 90-100%, because the air temperature is close to or meeting the dew point, but that doesn't mean it is actually sticky out. The winter is a very dry season. 

Currents humidity

Simply put, the dew point measures the moisture in the atmosphere. It is also the temperature to which air must be cooled in order to reach saturation.

*When thinking of dew points remember this: The higher the dew point = the more moisture present in the air = the more uncomfortable it will feel.

Therefore, when we are talking about muggy, humid, sticky, "air that you wear" days - you will hear the WDRB Weather Team mentioning the dew point rather than the relative humidity, because it is the more accurate term to use.

On the image below, the highest dew point in the regional is Peoria, IL - so that is the most uncomfortable location. While in Pittsburgh, the dew point is at 56 degrees, which is very pleasant and the driest location. 

7-21 regional dew points

To understand this even more, you can break dew points down into categories of about 5 degrees. 

A dew point of . . .

60-65 degrees: A magical number when you start to notice the humidity. 

65-60 degrees: It is steamy and getting uncomfortable. 

70+ degrees: Miserable and oppressive. 

So today we have dew points ranging from 69 degrees to 79 degrees. Which is a very sticky to miserable day. Not only that, but we also have very high air temperatures as well today. 

7-21 muggy meter

Taking into account the air temperature PLUS the dew point = heat index or the "feels like".  As air temps over the next few days rise to the mid 90s with dew points in the low to mid 70s, it will feel like the 100-107 degrees! You can get an idea of how the heat index works with this calculator

7-21 heat index

Because the temperatures and heat index is going to be so high, remember we are under a heat advisory until Saturday at 7 pm. Stay cool and take care of yourself! Read up on some heat safety guidelines here.

  7-21 heat advisory

We are also tracking some showers and storms for your Friday and weekend. Be sure to tune into WDRB News tonight with Marc and Rick to find out when and where they are expected to be.

Throwback Thursday: Australia's Pink Lake...

We always try to introduce you to the strange phenomena on Earth and explain the science behind the oddities. Tonight I introduce you to the "Pink Lake" of Australia named Lake Hillier....


Image Courtesy: Wiki

Is This Real? How Does It Happen?


It is not everyday that you see a lake that appears to look like it was filled with Pepto-Bismol! Lake Hillier is an odd pink lake and one of the few that we do have in the world. It's located on Middle Island in the western part of Australia. What makes it famous is obvious... the pink color and yes it is real.

It is believed that the odd pink color in these rare "pink lakes" comes from a combination of the following...

  • The alga Dunaliella salina
  • Halobacterium Halobacteria cutirubrum
  • A high concentration of brine prawn

The interesting part is how important the salt water is to the color. Once the or salinity exceeds the sea water and temperatures get high enough, alga begins to accumulate the red pigment beta carotene.  In the above mentioned conditions, the pink halobacteria begin to grow at the bottom of the lake very quickly as well. So we have a color of red/pink noted in the above organisms. As a balance is struck between the alga and halobacterium, we get this amazing pink color! If you draw a glass of water from the lake, you will see the pink color.

Now to the question everyone is asking... can you safely swim in the Pink Lake? The answer is yes! The lake has never been shown to produce any adverse effects on people. Cannonball!
