Storm Advancing

I didn't catch lightning this afternoon, but I got some pretty fierce storm clouds before that first thunderstorm this afternoon moved through. At some point as the wind was whipping up and the thunder moving closer, it occurred to me that standing out in the open next to a metal tripod was fairly idiotic (albeit exciting). Found it interesting that the color/tone of the sky in these two photos (taken within about 10 minutes and less than a mile of each other) was so different.

The following Special Weather Statement was just issued for Eastern Hampshire County:

...A FEW SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON AND EVENING...

A LINE OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO REACH WESTERN NEW ENGLAND EARLY THIS AFTERNOON. A FEW STORMS MAY PRODUCE WIND GUSTS AS HIGH AS 60 MPH...TORRENTIAL RAINFALL AND FREQUENT LIGHTNING...ESPECIALLY FROM THE BERKSHIRES TO THE WORCESTER HILLS AND IN NORTHERN CONNECTICUT BETWEEN 2 PM AND 4 PM.

THE STORMS ARE EXPECTED TO WEAKEN SOMEWHAT AS THEY REACH RHODE ISLAND AND EASTERN MASSACHUSETTS BETWEEN 4 AND 6 PM...BUT COULD STILL PRODUCE FREQUENT LIGHTNING AND HEAVY RAINFALL.

IF YOU HAVE OUTDOOR PLANS...KEEP AN EYE TO THE SKY AND HAVE A SAFE PLACE TO GO TO IF THUNDERSTORMS APPROACH SUCH AS A VEHICLE OR BUILDING. IF YOU CAN HEAR THUNDER...YOU ARE CLOSE ENOUGH TO BE STRUCK BY LIGHTNING.

Rainbow Chasing in Amherst (this afternoon)

Forget tornado chasing for the moment. This afternoon was all about rainbow chasing (for me anyway). As soon as I saw the rain pouring while the sun was shining I hit the road. Rainbow profusion - actually saw what appeared to be two or three completely different rainbows within about 15 minutes. As I pulled off the road at one point a passerby remarked happily, "all rainbows go to Amherst!" Of course, we were in Amherst, so it only seemed like that. I'm sure people were seeing them all over the Valley, but Amherst's rainbows were spectacular.

Daylight's Last Glowing Embers

Friend of Head in the Clouds Amherst, Meg Rosa, captured another gorgeous sunset. Yesterday afternoon's storminess to our west never really reached us here, but the post-storm clouds still made it beautifully memorable. Thanks for sharing, Meg!

New Cloud Type Recognized - First Time Since 1951!

As a blog claiming to be "in the clouds," it's hard to believe I've never posted on the subject of cloud classification or, more to the point, on the imminent formal recognition of a new variety of cloud. To cloud geeks everywhere this is serious and exciting business. Especially so this summer, as a few weeks ago the World Meteorological Organization* accepted a new type of cloud into the fold. Named "asperitas," after the Latin for ‘roughness,' it's the first new cloud type recognized since 1951! According to the Cloud Appreciation Society (of which, yes, I am a proud member), this new cloud was identified thanks to photographs sent in by their members – like this one by Sarah K. Davis, taken over Statesboro, in Georgia. (Brief aside here - for whatever reason, "cloudspotting," not even really a thing in the U.S., tends to be hugely popular in other countries, so I always find it encouraging when people in the U.S. show more than a passing interest.)

The journey towards recognition of asperitas began back in 2006, when the Cloud Appreciation Society started receiving some photographs of a strange cloud over Iowa. With rough, turbulent and contorted waves, these formations didn’t seem to fit within the existing cloud classifications. As the Society wrote in their recent newsletter,
We weren’t sure what to call these clouds when we added them up on our photo gallery. There is already a term for wavy clouds, they’re called undulatus, but these turbulent waves seemed different from the usual undulatus. And those 2006 examples weren’t the only ones. We soon noticed other examples. These same dramatic wave clouds were being sent in from other parts of the world. Each time, we thought there’s another of those weird, nameless clouds.
By 2008, the Cloud Appreciation Society decided to give this cloud a name, which was subsequently tweaked by the WMO to conform with their Latin naming system. And no, Harry Potter fans, "Voldemort" was never considered during the naming process, no matter how much the new cloud looks like something he would conjure.

A cloud type is only official when it appears in the WMO’s International Cloud Atlas, an international reference for meteorologists (also prized by cloud geeks, cloud photographers, and nature lovers). The next edition of the Cloud Atlas is scheduled to come out in 2016, at which point aspiritas will be included right alongside some 100 recognized cloud combinations. In addition, a whole new cloud classification species, Volutus (from the Latin volutus, which means rolled) is also slated for inclusion in the 2016 edition. 

Now here's where it gets even more interesting for cloud aficionados who also know their way around a camera. The WMO, through the Cloud Appreciation Society, is soliciting photographs of the new cloud type, and to facilitate that process, the Cloud Appreciation Society has just launched a competition to find the best photograph of asperitas, which will appear in the International Cloud Atlas. This is your chance to make cloudspotting history, as the photo will be the reference image against which all asperitas spottings will be judged. The winner will be announced at the Cloud Appreciation Society Conference in London on September 26, 2015. Go here for more information. 

For those of you whose cloud knowledge begins and ends with "cumulus" and "cirrus," welcome to a whole new world! And don't forget to look at the road from time to time when you find yourself cloudspotting while driving.

Summer Lightning

Captured some lightning action on video this evening (about an hour ago, at 7:15 pm). Apologies in advance for the under-the-breath invocation. I had been seeing action in the distance and didn't expect something quite so over-arching!

A hard rain's a-gonna possibly fall

Storm over Hadley
Photo taken by S. Vardatira, July 24, 2009
You wouldn't know it to look outside at this moment, but two severe weather alerts have just been posted for today. First, we are under a heat advisory through 6 pm this evening (the worst of it between 1 pm and 5 pm). Expect heat index values (what it will feel like outside) around 100 degrees due to temperatures in the low 90s and dewpoints near 70. The second alert concerns the risk of strong to severe thunderstorms this afternoon and evening, with the highest risk north of the Mass Pike - which includes us here in Amherst, of course. These thunderstorms may bring locally strong to damaging wind gusts and possible hail.

The biggest uncertainty is whether or not these isolated strong storms merge into a larger complex of thunderstorms. If that happens, we could get dangerous cloud to ground lightning, heavy rain, localized flooding, and significant wind damage. So keep a watchful eye as you go about your afternoon. Drink plenty of fluids and if you hear thunder, head for indoor shelter.

All on a summer day at Puffer's Pond

South Beach in July, Puffer's Pond (Amherst MA)

Although the temperature topped out at 89 F this afternoon at Puffer's Pond, the crowds weren't as intense as you might expect on such an uncomfortably hot day. I theorize that some people, wanting to avoid mobs at Puffer's, may have sought relief at pools and other swimming holes across the area. At the same time, it's possible the crowd on the beach just seemed a little thinner because so many people were out on the water courtesy of air mattresses and inflatable boats. Whole groups had also congregated above and below the waterfall, along with a handful of young men who were rock jumping (a wholly prohibited and incredibly dangerous activity). The rock jumpers left the area in a hurry shortly after they realized I was photographing them. Ah, the power of a camera!

I took a narrow path along the shore from Fisherman's Point towards the waterfall, on the way discovering a lovely secluded spot where a couple had set out a picnic, complete with h'ordeuvres and a small carafe of wine. They were bobbing in an inflatable boat a few feet off shore, and when I apologized for intruding on their site, they laughed and waved their hands across the water, as if to encompass the whole summer scene. "Come on through," they urged, "this is for everyone."

A tale of two seasons - at Puffer's Pond

Two photos, one taken in January and one taken in July, at Puffer's Pond. Both photos taken from the same general vantage point as the sun was going down.
