Do you love weather? Do you like to work with numbers and weather instruments? Perhaps you'd like to become a volunteer weather observer in Northern Maryland for the Community Collaborative Rain, Snow and Hail Network (CoCoRaHS). 

Bruce Sullivan is reaching out to the WeatherBlog in the hope that our readers might include folks who would be interested in joining the CoCoRaHS team in this area. You would be contributing to the gathering of data such as these.

The group is organizing another training and information session for would-be observers, this coming Tuesday at 3 p.m., at the U.S. Geological Survey office near the University of Maryland Baltimore County. The address is USGS, MD-DE-DC Water Sciences Center, 5522 Research Park Drive, Baltimore, MD, 21228.

(An earlier version of this post listed a 4 p.m. start time. That is incorrect. Session begins at 3 p.m.)

You can also email Bruce at bruce.sullivan@cocorahs.org

Finally, you can read more about the organization here. And here.

Flocks of robins aren't earlybirds

I've had a number of startled readers drop me a note to report seeing flocks of 20-or-so robins converging on backyard trees, gobbling up leftover fruits and berries. We had a bunch of them in our back yard in Cockeysville on New Years Day, feasting on some sort of red berries in a low tree at the edge of the woods. Sun reporter and columnist Fred Rasmussen spied a robin in a tree in Ruxton:

"Isn't it a little early for them to be back in Maryland? It really shocked me. Seeing them in late February or early March is more normal," he said.

Well, apparently that's when we expect to see them. They're the traditional harbinger of spring, after all. But it's not unusual to have a flock of foraging robins in Maryland in mid-winter, according to David Cursom, director of bird conservation at Audubon Maryland DC.

"There is a population that overwinters in the coastal plain of Maryland," he said. "The largest groups are over on the Eastern Shore, a regular roost of robins. I believe around 14,000 have been counted in Easton."

Robins, it turns out, are strongly migratory birds, but they breed all over North America. So, there are populations that breed well to our north, for whom Maryland's coastal plain is "South."  Those that breed here likely migrate in October to the southeastern states, and along the Gulf of Mexico. They return in March and April.

"The groups people are seeing now are part of the wintering population that are moving around. As the weather fluctuates between cold and mild, the robins move accordingly to find food," Cursom said.

Waterspout? Dust devil?

Readers: Did anyone else spot anything like this in Harford County Saturday? Did anyone get a picture? If so, email it to me at frank.roylance@baltsun.com  Thanks.

"Mr Roylance,

"My wife and I were driving westbound on US40 this afternoon (Saturday, 30 June), at about 1:45 PM.  As we approached MD 543 in Belcamp (in Harford County) I noticed a thin, dark, mostly vertical column of SOMETHING rising from the vicinity of the Bush River toward the sky.  I could not tell what it was, but I definitely saw this thing, and my wife saw it too.  It did not last very long, and it eventually faded completely away.  It almost looked like a shadow, but it moved and bent a little before it faded.  It did not look like any kind of smoke that I have ever seen.  We thought it sort of looked like a big, thin, dust devil.

"The sky was fairly clear, with no storm in the area, and no weird winds were obvious from where we were driving. Could this have been a small waterspout?  Were the conditions today right for a waterspout to form?  I know from a TV weather show that waterspouts form in a different way than regular tornadoes, and they are much weaker.

"Unfortunately, I did not have a camera on me at the time. Sincerely, Monroe Harden, Havre de Grace, MD"

Frog in the washer

I'm going to stretch the parameters of this blog a bit today, just because I can, and because I have a story to tell. This story was inspired by real events over the weekend in Cockeysville, and by today's Sun, which in the spirit of a gorgeous stretch of Spring weather includes articles about crabs, whooping crane reproduction, flowers and frogs. (Did you notice the mention of "weather" there? That will stand as justification for this story.)

OK, so my wife and I are out on the WeatherDeck in Cockeysville, hosing off the pollen and the oak flowers in preparation for the arrival of in-laws for Mother's Day weekend. We pull the vinyl covers off the deck furniture, which have protected tables and chairs from the weather all winter - or at least they did until a windstorm threw them aside a few weeks back. We never bothered to put them back in place.

We toss the covers off the deck onto the lawn below, where they rest for several hours while we finish hosing off the deck and potting some flowers.

Then, my wife gathers up one of the covers, hauls it into the house and stuffs it into the washing machine for a good scrubbing before we put it away for the season.

A couple of hours later, I'm working at the computer when I hear a plaintive wail from the basement laundry room. Now, I've been married to this person for nearly 37 years, and you'd figure I'd be able to gauge the nature of the emergency from the tone of the wail. And that would normally modulate how fast I have to scramble down two flights of stairs.

Not this time. It doesn't sound like "I've fallen and broken my leg."  But then again, it doesn't sound like "Come look at what I found!" either.

So, I choose a midling pace, taking care not to fall on the steps and break MY leg. I find my wife standing a good five feet from the washer. She appears intact, but she is looking at the machine as though the newborn monster from ALIEN had emerged from the deck table cover.

Amid the gibberish coming from her mouth I catch the word "frog!" So I begin pulling the now-twisted cover from the washer and peering deep into the machine. And there it is - a very small, very dead, but impressively clean frog. Whether he got caught up in the cover while it rested for months on the deck, or for hours on the lawn doesn't seem important anymore, somehow. So I scoop him up in a paper towel and commit his limp remains to the trash can.

Oddly enough, we should have seen this coming. A year or two ago, during the exact same Springtime ritual, a very similar cry had reached me from the laundry room. That investigation yielded a similarly clean, but very much alive toad at the bottom of the washer. He was returned to the lawn from whence he came, hopped a bit, and presumably made a fine impression on the next female toad he encountered.

The good news is that the ecosystem that surrounds the WeatherDeck is healthy enough to support a lively population of amphibians. The bad news is that some of them can't survive the wash cycle.

Take a wet suit

The Memorial Day weekend may be the official start of summer, but there's nothing summer-like yet about the water temperatures at the beach. Data from the weather buoy in the Delaware Bay shows water temps not quite 60 degrees. Actually, that's about normal, maybe even a degree or so warmer than normal. But take heart; June is a big warm-up month. You could also head for Cape Charles, Va., where the water temperatures is closer to 67 degrees.

Kayaker caught in Weds. squall

The gusty snow squall that whipped across the region early Wednesday morning caught all of us by surprise. But most of us were safe indoors, or in cars. Don Baugh, vice president for education at the Chesapeake Bay Foundation, was in his kayak, out on the Severn River, commuting to work. His unusual, but normally placid morning routine suddenly became very frightening.

"I ... was able to outlast the blow, but barely," he said. Here's his story, sent to the WeatherBlog via email:

"I have paddled 14,000 miles, through 14 years of commuting, and tackled four tropical depressions, and countless northwesters, nor'easters, and squalls. This is the first bad weather that caught me off guard.

"I glanced to the horizon, when I was at the mouth of the Severn, about 1 mile from shore, and my reaction was whoa, this is not good. That storm came out of nowhere. I raced to shore, but clearly was being overtaken.

"When the storm hit, I was about 3/4 mile from shore, and had to head into the wind, shifting my course, as the winds shifted from SW to W to NW. I had my fast racing kayak, as I was not expecting harsh winds, which cannot take any gusts on the beam as they can push you over in a fraction of a second.

"I kept paddling into the wind, hard, trying to keep some forward momentum, so that my rudder would correct course changes. With head down to keep my hat flying, blinding rain, and with a steady 50 mile wind, it was a question of time. I could not last 30 minutes, maybe not even 15, before I would succumb, tip, and then really have issues to deal with. The water is cold.

Editor's note: Water temperature at Thomas Point Light this morning is 49.3 degrees.

"The sky behind the blast was blue, so I knew the back side soon would allow the winds to moderate. They did to 25 mph, or so, and I continued on my merry way, but feeling like I was visited by some phantom stalking me in the night, and whipped."

Baugh later called the National Weather Service forecast office in Sterling, and asked whether this event had been forecast.

"As someone who spends lots of time on the water, I want to inquire about this storm, so that it may inform future decisions ... I did talk with a ...  forecaster. They apparently did issue an alert shortly before 7 AM, a little after my departure. This apparently is a freak early spring phenomena when winds aloft are able to penetrate to the surface, with rain. They sometimes only have 15 minute warning of an event.

"This was almost exactly the same scenario as when the Baltimore ... (Harbor) Taxi capsized two years ago. There were reports of winds to 51 knots (58 mph) at the same time, but somewhere else. The winds I encountered I estimated to be about 50."

Glad you made it to shore intact, Don. It's the last time I'll complain about the JFX.

Frontal passage brings plenty of rain

The cold front sweeping across Maryland today has brought a gusty squall line and more than an inch of rain to some locations. There are reports of thunder, trees down, and BGE power outages totalling more than 11,000, mostly in Carroll and Baltimore counties. Some wind gusts topped 60 mph, even 70 mph in the mountains to our west.

Temperatures are beginning to fall across Maryland as the front approaches, but still linger in the 50s in most places. But it's already dropped to 34 degrees in Garrett County. Lows tonight in Baltimore will drop below freezing, so watch for icy spots.

Northern Lights dazzle Marylanders

Photos just in! A blast of atomic particles and magnetic energy blown off the sun late last week reached Earth last night, creating a spectacular display of Northern Lights as far south as Maryland, North Carolina, Colorado and Oklahoma. The photos are already on the Web, including some shot in Maryland. The aurora alert has been extended into tonight as more solar debris is set to arrive. Here's an image of the eruption last week that caused all the fuss. (It's the flare at the center of the photo.)
