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…

Hurricane Danny May Be at Peak Strength

Danny now has winds near the center at 115 mph, but it is actually a rather tiny storm. Latest model runs continue a west-NW track but dry air is just to the north and wind shear will begin to impact the storm in about 48 hours. This should weaken it and the latest hires numerical model guidance shows just that. The intensity forecast from the HWRF model shows it weakening …

Tropical Storm Danny Forms in the Eastern Atlantic.

Every 6 years there is the chance that I get a hurricane named after me,and this year is looking good. Tropical Storm Danny has formed and is slowly strengthening. Model guidance is all in rather good agreement, especially the dynamical models that tend to have the best skill. Wind shear is strong to the north of the system, but it will likely stay south of the shear until it approaches …

The Ugly Side of August Arrives in The Northeast Next Week

Unlike much of the Plains and the Deep South, the summer has not been that hot across the mid-Atlantic and Northeast U.S. but next week is going to bring the ugly side of August to much of the region. The heat will likely make it all the way into Toronto and Montreal and affect millions of people. This same weather pattern a month ago would likely bring highs in the …

Was Your Record High Temperature A Result of Climate Change? Probably.

A paper in Nature Climate Change today is getting international press and for good reason, It contains a rather astounding statistic. Here is a quote from the beginning of the paper with my highlights in red:  Climate change includes not only changes in mean climate but also in weather extremes. For a few prominent heatwaves and heavy precipitation events a human contribution to their occurrence has been demonstrated1, 2, 3, 4, 5. Here we …

NOAA: Earth Had Warmest Winter On Record

Earth just had it’s warmest winter on record, and this past February was the second warmest on record. This from NOAA/NCDC During February, the average temperature across global land and ocean surfaces was 1.48°F (0.82°C) above the 20th century average. This was the second highest for February in the 1880–2015 record. The highest temperature occurred in 1998, at 1.55°F (0.86°C) above average. During February, the globally-averaged land surface temperature was 3.02°F …

Making Snowfall Forecasts More Accurate

We are at the cusp of some amazing technology that will hopefully make forecasting snowstorms, like the one predicted yesterday, much more accurate. I was on a local program produced by the TV station I work for (WBOC-TV) last week, and I showed a couple of smart phone apps that may eventually make a real difference in forecasting. Making better forecasts requires higher resolution models and that means more data …

Hanging With Smart People at AGU

The AGU meeting every December in San Francisco is truly an amazing experience, and while I only was able to be there for two days, it was well worth flying across the entire continent and back in 48 hours. Here are some sights and sounds from the AGU that I and others made. Up first is meeting Geoph Haines-Stiles one of the senior producers of the original COSMOS with Carl …

City Lights, On A Cold and Snowy Night

The Suomi satellite has the ability to get images of the Earth at night, and this week it grabbed one of the prettiest shots yet, under the light of a full Moon. With clear skies and snow on the ground, you can see the snow and if you look closely you can see some high clouds on top of the lights across portions of Iowa and Minnesota. You can get a much …

Super-Fast Jet Makes Jets To Europe Super-Fast

Departures were being delayed from the U.S. to the UK to keep aircraft from arriving to early in Europe. You have to feel for the folks flying from Heathrow to Seattle though; add two hours to an already LONG flight! I experienced this once on a flight from Atlanta to London, and arrived an hour early. We sat on the plane though waiting for a gate to open up!

Seems It Finally Rains In Southern California (and it snows too!)

Heavy rain and snow is moving into California tonight, as an intense surface/upper level low pressure system taps warm tropical air to the south and shoves it into California. California gets most of its rain in winter and you might be surprised to know that most if it comes from just 5-6 storms. The water vapor imagery from the GOES shows the storm well. Keep in mind that you are …

The Governor of New York Owes an Apology to a Bunch of Meteorologists

The Governor of New York, Andrew Cuomo, really stepped in it on Saturday. He’s now getting a firestorm of criticism, and he deserves every bit of it, but I want you to understand why before I go into what he said. There is an old rule among weather forecasters, and it goes like this- “Never forecast a record, you will probably be wrong!”. Now I, and many others, have broken …

Indian Summer For The End of November?

There are growing sign,s that after one more blast of even colder air next week, we will see some much warmer air over the Central and Eastern U.S. as we head into Thanksgiving. Indian summer may be on the way! The forecast below is based on an average of many long-range model runs of the Climate Forecast System. Research shows that an average of model runs provides a more accurate …

Forecasters and Science Writers Knock Weather.Com For Hype

A low-end nor’easter is bringing wind and rain to much of the Northeast U.S. this evening, and Gale Warnings have been posted in the Atlantic as well. As nor’easters go, this is not really a big one, and we will see far worse over the coming months, with some of them bringing snow instead of rain.This is what I told my viewers here in Maryland/ Delaware, and so did many …

Saharan Dust Storm Below Towering Thunderstorms

Here are the particulars of the image, and what you are seeing from NASA Earth Observatory: More dust blows out of the Sahara Desert and into the atmosphere than from any other desert in the world, and more than half of the dust deposited in the ocean lifts off from these arid North African lands. Saharan dust influences the fertility of Atlantic waters and soils in the Americas. It blocks or reflects …

Crazy Summer Weather pattern Is About To Flip

The summer of 2014 has been unusually mild in the Midwest and portions of the East, and brutally hot and dry in the West. The heat and drought in the NW corner of North America has led to raging forest fires that have spread dense smoke over the northeast and across the Atlantic to France, and the drought in California has reached the worst possible level: exceptional drought. Mother Nature is …

This Is Why Canada and The West Are Burning

NASA posted this map of the temperature anomalies over North America for July, and you can easily see why we there is so much wildfire activity in the U.S. West and Canada North. This is why dense smoke is travelling thousands of miles to the Eastern Seaboard. The heat out west has now pushed much of California into Exceptional Drought” status.

Wildfire Smoke Makes Cool East Coast Temps Even Cooler

In spite of an unusually dry and cool air mass over the eastern seaboard of the U.S. this afternoon, the sky is a milky white due to smoke from the wildfires in Western and far northern Canada. An even denser layer of smoke covers the western portions of Hudson Bay as well. Here is the view of the sky over Maryland at 630 PM, and the usual deep blue sky …

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 …
