I’ve Never Seen Hail Like This Before

Rain drops and hail stones need something to form around, and we refer to this as condensation nuclei. The image below shows something else though. A tornado in the Texas panhandle last night picked up stalks of corn, and lifted them high into the atmosphere, where water froze on it, turning it into a hail stone. The picture was taken by Johnny Goodson of Pampa,Texas. That was one powerful updraft, …

Did Climate Change Make “This” Storm Worse? Perhaps.

The AMS has published its annual look at how climate change may have impacted certain major weather events, and it makes for some fascinating reading. This kind of research is called an attribution study, and they can be very informative. One of the most famous, was done by Dr. Ben Santer (Nat. Academies) that showed how different greenhouse warming looks vs. warming due to an increase in energy from the …

Two Incredible Images

These two images speak for themselves. One is from the Suomi satellite, which can take images of the Earth lit by moonlight alone. and the second image needs little or no explanation…

Historic Storm Threatens the Mid-Atlantic

Hurricane Joaquin is now a Cat 3 storm with 115 mph winds tonight, but even if it does not turn toward the Mid-Atlantic coastline, we will see a significant coastal Nor’easter across the Mid-Atlantic from New Jersey to North Carolina including the Delaware and Maryland Beaches. This is because of a strong pressure gradient between a large Canadian high pressure over New England and a low pressure system in the Carolinas. …

The Great Derecho Was Three Years Ago Today

  Three years ago tonight I was introducing the viewers of my evening weather broadcast to a new weather term: The Derecho. Here on the Eastern Shore of Maryland, I first mentioned it on air around 5 PM. Through the early evening, I watched it get closer and closer, and by mid evening it was likely that we would be affected. When it arrived at our studios in Salisbury, the …

The Ghost of Bill Heads for The East Coast

It’s a summer weekend here in the Mid-Atlantic, and that means thousands are on the beaches from Fire Island To Ocean City in Maryland, while at the same time, the Firefly music festival just north of Dover in Delaware has drawn a crowd of 95,000 people to see such acts as Paul McCartney (I typed that name standing up of course) and Snoop Dog. Now, add in the remains of …

Severe Flood Threat for Texas and Oklahoma Rising

Virtually all of the global and regional numerical weather models are showing the potential for very heavy rainfall from what will soon be Tropical Storm Bill in the Gulf. Even if this region had not had historic flooding in May, this would be a big deal, but with the soggy ground, we are now looking at the potential for a very severe and costly flood event. There are some indications …

Thunderstorms, On a Scale of 0 to 5

The Storm Prediction Center in Norman issues all of the weather watches for severe thunderstorms, and tornadoes, across the U.S. In addition, they also put out an outlook several times per day that indicates the threat level across the country over the next several days. In the past this outlook had three levels for severe storm risk: slight, moderate, and high, but this has now been revised, and the graphic …

Jaw Dropping Images of Super Typhoon Maysak

NASA Astronauts have been sending back jaw dropping images of Super Typhoon Maysak, headed toward the Philippines with winds of nearly 240 km/hr. Astronaut Terry Virts uploaded some incredible photos of the eye of Maysak to his Twitter account as well and they provide one of the best views of an intense tropical cyclone ever made from low Earth orbit. The Super Typhoone is likely going to hit the northern Philippines in …

Coldest Air of The Winter Headed For the NE U.S. and Midwest

A true outbreak of Polar air is headed for the northeastern quarter of the U.S. beginning Thursday. It will actually come in at least two and maybe 3 waves. The first wave will bring snow showers and plunging temps on Thursday to the East Coast from Virginia to Maine, and another surge will arrive Saturday evening with even colder air. A true Polar air mass often brings a dusting of …

East Coast Blizzard Brewing?

  There are increasing signs this early Sunday morning that the winter of 2015 is about to go into high gear. A major nor’easter is likely to develop Monday and move NE to off the New England coast by Tuesday evening. A word of warning here- there is still a lot of uncertainty in the strength and track of this low and that will play a big role in how …

Cool Science Pics

Thought I’d share some cool pics taken from Space today. The first one below is from the past week, and is a great view from the ISS courtesy of Astronaut Barry Wilmore. Notice the city lights shining through the clouds. I forecasted a sunny Sunday in Maryland and Delaware today. Missed it by THAT much! Severe storms hit Oklahoma Sunday evening ahead of a powerful tropospheric low pressure system. The …

Using Your Smartphone to Improve Weather Forecasts and Warnings

You need to download an app called mPing. mPing is a free app developed by scientists at the University of Oklahoma (My alma mater!) and the National Severe Storms Laboratory in Norman, Oklahoma, and it’s aim is to improve forecasts and weather models by letting everyone know what type of precipitation is falling on you right now. You might say, that we have radar for that, but in reality, radar …

Rare Mid-Summer Tornado Outbreak Possible In Midwest Sunday

An unusually strong summer cool front is expected to kick off numerous super-cell thunderstorms Sunday across the Midwest and even into the Mid-Atlantic/Northeast. With thousands of folks at campgrounds and beaches, the possibilities that the storms may catch folks in the open and away from sturdy shelter is much higher than normal. Just this week, an EF1 tornado hit the Eastern Shore of Virginia, and left two dead and over …

The Great Facebook Blizzard of 2014

At the AMS Broadcast Meteorology conference last month in Lake Tahoe, I presented a talk about widespread rumors on Facebook last January that a paralyzing snowstorm was coming. This is just one example of the love/hate relationship that meteorologists have with Facebook, and I was quoted in an article on TV News Check about this as well a couple of weeks ago. As I told the reporter for TV News …

True Colour View of Arthur from NASA (Doppler sees winds at 100 MPH)

Frying Pan Shoals off the North Carolina coast caught a gust to 99 mph on their weather station. They were in the eye-wall of Hurricane Arthur at the time. Here on the Delmarva Peninsula there is a real risk of extreme rip currents behind the storm. With thousands of folks streaming to the Maryland and Delaware beaches for the holiday weekend, this is a serious threat. Something to think about: …

Yes, El Nino Is Coming But It’s Probably Not What You Think

  An El Nino is probably on the way for this autumn and winter, but despite what you may have heard about floods and fires, it’s not looking (right now) as if it will be a strong one. The strength of the El Nino IS a big deal however, because weak to moderate El Nino episodes tend to have different and milder impacts on worldwide weather, than the super strong ones …

Meteorology In The High Mountains Of California

  I am at the American Meteorological Society’s 42nd Conference on Broadcast Meteorology at Squaw Valley,Ca. We are just outside of Lake Tahoe, and I drove up from Las Vegas, through Death Valley and by Mammoth Lakes. The temperature ranged from 96 in Death Valley to 46 at Mammoth, and when i awoke here in Squaw Valley this morning it was 28 degrees! I thought I’d share some pics of …

A Busy Tuesday at the Hazardous Weather Test Bed in Norman,OK

If a thunderstorm has an extremely strong updraft it will push all the way into the stratosphere before weakening. The air actually starts to get warmer in the stratosphere, and a warm bubble of rising air suddenly finds itself colder than the air around it, and will eventually sink back down. So, the higher the updraft penetrates, the stronger it must be. This is why meteorologists are keen to know …

Here’s How Scientists Are Improving Warnings of Dangerous Weather

  Imagine a hot July weekend, and the beaches and or area lakes are packed with thousands of folks enjoying the sun, sand and water. While there is a chance of thunderstorms in the forecast, the skies are sunny, and the weather is the last thing on the minds of most people. It’s the first thing on the minds of weather forecasters, however, and if strong thunderstorms with deadly lightning …
