Last of the 30's?

No more 30's?

This morning's low here at the house was 39. We recovered well and ended up with a high of 77.

Have we seen the last of the 30's in Alabama? I think so, at least for most of us in the state.

Hazardous wx outlook

The Huntsville NWS just issued the following HWO a few
minutes ago:

SCATTERED THUNDERSTORMS ARE POSSIBLE FRIDAY...WELL AHEAD
OF A STRENGTHENING STORM SYSTEM OVER THE CENTRAL PLAINS.
THESE STORMS ARE NOT EXPECTED TO BE SEVERE AT THIS TIME.
A MORE ORGANIZED LINE OF SHOWERS AND THUNDERSTORMS WILL
DEVELOP AHEAD OF A COLD FRONT THAT WILL CROSS THE AREA
LATE FRIDAY NIGHT THROUGH SATURDAY MORNING. THE COMBINATION
OF SUFFICIENT INSTABILITY AND WIND SHEAR COULD SUPPORT
STRONG TO SEVERE THUNDERSTORMS...ESPECIALLY ALONG AND WEST
OF I-65. THE PRIMARY THREATS APPEAR TO BE HEAVY RAIN...
STRONG WIND GUSTS AND POSSIBLY LARGE HAIL.

Cool change

This morning's low was 37 and the high was 64. It was quite a nice day of blackberry winter here in North Alabama.

Virginia tornadoes

At least three tornadoes struck southern Virginia yesterday. As of this morning over 220 injuries and have been reported so far. It is miraculous that there have been no fatalities reported. This was a very destructive tornado in an urban area. A storm survey will be done by the Wakefield NWS on the tornado damage by the NWS to assign an EF rating. Based on some of the damage I have seen, an EF3 rating may be possible for the tornado in Suffolk County. This would require the QRT (Quick Response Team) to be called in to make that determination. This same general are received tornado damage one week ago.

Check out this video of the tornado from April 28, 2008 taken in Chesapeake and Suffolk, Va.

Follow up from April 11 Storms

During my chase experience on April 11, I captured some video and
still pictures of impressive wall clouds and mesocyclones. I suspected
there might be a tornado or two associated with these impressive
structures but it was impossible to see. Later the Huntsville NWS
confirmed two EF0's in Marshall County.

A few days after the event I noticed some minor tree damage in the
area close to my home in Northern Cullman County which I reported
to the NWS. These areas have been ruled EF0 tornadoes.

Here are a few excerpts from the NWS Huntsville

Fishing at Smith Lake for Spring Break


Created with Admarket's flickrSLiDR.

It was a beautiful weather day at Smith Lake Thursday for fishing. No, it was not a good day for actually catching fish. We were there for 9 or 10 hours and the fish caught more of us than we caught of them. I say that because Matt gave us all a big scare when he leaned into the water to get his hook untangled and he fell into the water. The boys said the never saw me run so fast. Another gentleman was closer and pulled him out. Prior to that David severely bruised one of his toes by walking around barefoot on the dock and hitting it on a metal tie back.

Weatherwise, we had mostly sunny skies with highs in the low 80's, which created a great opportunity for me to get a nice sunburn.

Wild weather in Texas yesterday


There were 10 tornado reports shown by the Storm Prediction Center yesterday.

I had a chance to watch some amazing streaming video yesterday by some storm chasers in Texas, including Dave Drummond, who caught a cone-shapped tornado on his live stream.

My friend James Payton relayed an interesting chase account and photos from his friend Cary Allen at KCBD-TV 11 in Lubbock, TX.

Frightning lightning

Plane safe after lightning strike - Baltimore Sun

"A passenger plane landed safely at BWI Marshall Airport after being struck by lightning yesterday morning, according to an airport spokesman.

The Continental Express plane was struck about 10:30 a.m., said airport spokesman Jonathan Dean. No one was injured, and the plane landed without incident, Dean said."

Follow up from Friday



As expected, there were not many problems with severe weather in Alabama and what did occur was in the southwest part of the state. The only report I could find was that two pine trees were snapped along US Highway 45 south of Fruitdale in Washington County at around 8:15 p.m.

There were three tornadoes reported in South Mississippi, in Copiah, Hinds, and Winston counties. There was an injury reported near Louisville in Winston County.

Severe weather tonight?



The Storm Prediction Center (SPC) maintains a "slight risk" for severe storms later today and tonight over SE Louisiana and South Mississippi. The reason, I think, that the area outlooked for severe weather is so small is that CAPE (convective available potential energy) values are predicted by the models to be rather low, as shown in the GFS output shown below for 1 a.m. Saturday.



One thing I have learned, though, is that significant tornadoes can and sometimes do occur in relatively low CAPE environments if helicity (the amount of wind shear in the lower atmosphere) is great enough. Healthy shear values are predicted by the models to exist across Alabama at 10 p.m. tonight according to the RUC model. This is shown in the map below. This is especially the case in the southwest part of Alabama.



I am not expecting a major severe weather outbreak, but this one definitely bears watching. This is especially true because last Friday models seemed to underestimate the amount of instability and the fact that the calendar shows we are still in mid-April. The fact that this is a night time event may help to limit stability as well.

Regardless, I still think it is a good time to be ready for any severe weather that may pop up. As J.B. Elliott and James Spann often point out, with severe weather, "expect the unexpected".

Please be weather aware tonight between 6 p.m. and 6 a.m. Saturday!

Great weather research from UAH


Above ARMOR radar image from UAH of the 2/6/08 Lawrence County, AL tornado signature

Michelle Miklik shared this interesting article about some potentially valuable research underway at UAH.

Unexpected image from killer tornado might lead to precise storm warnings
"An unexpected radar image of air-borne debris from the Feb. 6 tornado that killed four people in Lawrence County, Ala., might help scientists develop better tools for warning the public when and where strong tornadoes are on the ground. Scientists in the Earth System Science Center at The University of Alabama in Huntsville (UAH) are studying radar data from the early morning tornado to see if the radar signature from the debris is so distinctive that computers can be programmed to instantly recognize it, so more timely and precise warnings might be issued."

Today's weather theme song...

Today's weather in Vinemont: Low 42 - High 75.

Today's wx theme song: "Blue Clear Sky" by George Strait. "
Surprise your new love has arrived Out of the blue clear sky." Oh, and here's a video to go with the theme song of the day. By the way, apparently there is nothing on YouTube with George Strait himself, so check this out as a fun alternative!




Have a great day under the Blue Clear Sky everyone!

A beautiful start to a great day!



A huge thank you to fellow ABC 33/40 Skywatcher Michelle Miklik for sharing these great photos with me! She took these pictures this morning along Highway 431 around Alexandria, Alabama. Alexandria is located between Anniston and Gadsden on Highway 431, just northeast of Fort McClellan. I'll never forget taking a 25+ mile hike at Fort McClellan as a Boy Scout many years ago. Please don't ask how many years ago! : )

Freeze and light frost here




Low this morning here was 31. There is light patchy frost.

Monday, April 14, 2008

Freeze Warning!

There were numerous reports of ice falling from the sky today in North and Central Alabama. There is considerable debate as to whether it was sleet, hail, graupel, or all three.

My friend Mike at work said there was ice on his windshield this morning before he left for work. My theory is that was sleet. I think the precipitation began as sleet. Alabama weather legend J.B. Elliott said just before 2 p.m. that, "There are now numerous very small convective showers. These are producing brief but quick periods of sleet. We have had numerous reports of that across North and Central Alabama....So some of the precipitation can be brief small hail due to the convective nature of the showers. The technical name for that is “grauple” which means small soft hail. It is usually quite small. That term (grauple) has been around forever but rarely used in weather information."

Temperatures will fall quickly tonight under clear skies and will drop to the freezing mark or a little below. In some areas, especially in the northwest corner of the state and in the higher elevations, sub-freezing temperatures may hold on for as long as 6-hours early tomorow. That has prompted the National Weather Service to issue a Freeze Warning from midnight tonight until 9 a.m. Tuesday.

More anecdotes from Friday's severe weather...




Thanks to Nathan for sending me the above radar captures from Friday's storm. Also thanks to Rick Lipscomb for his radar support as I followed the storms.

Storm surveys are underway by the Huntsville and Birmingham NWS Offices.

Friday April 11 thankfully looked more scary than it turned out to be. There were numerous reports of wall clouds, funnel clouds, and NEXRAD radar images of hooks and rotation. Thankfully, all of this resulted in no known injuries in Alabama, and very scattered damage reports. I suppose that made it an ideal day to chase storms, if there is such a thing in Alabama.
Friday was a textbook case as to why chasing is so difficult in the South. These were better conditions than normal to spot storms, but it was still difficult at times. After eating lunch with the unit I supervise at work, I checked back on the weather situation. Much of Alabama had been placed under a tornado watch and James Spann was streaming live on ABC3340.com for a tornado warning in Marion County.

Storms were popping up rapidly, more than forecast by the meteorologists and models. I was most concerned about the storm near Glen Allen in Marion County, Alabama. I looked at the radar and determined that it was about an hour away from western Cullman County, where my boys attend school. I was dismayed to learn that the schools in Cullman County were releasing students at 1 p.m. By my calculation, that was very close to the time when the mesocyclone in Marion County would be in the area where my boys' school is located.

I called my ex-wife who was in complete agreement with me. She began high-tailing it to the west out of Cullman. Our goal was to get our kids out of harm's way before the storm hit. She wasn't sure she would make it. She did, and I was thankful. As she and I were talking, I heard reports of damage out of Winston County from fellow storm chaser, Brett Adair, who was streaming live video back to James Spann at ABC 33/40. My concern now was for the students in Cullman County who would be in buses as a mesocyclone with a possible tornado was headed their way.

While all this was going on I was updating co-workers on the weather situation and letting them know that I was thinking about leaving at 1:00. I emailed my boss, who, after asking me if I was storm chasing and showing concern for my children, graciously allowed me to take leave. I was relieved to learn that my ex wife had gotten our children to shelter ahead of the storm. Credit is due her for driving them to three separate shelters as they dodged three tornado-warned mesocyclones Friday afternoon.

I decided to head south to either I-65 Exit 308 (Hwy 278) or a little further north and closer to the storm at Exit 310 (Hwy 157). Out of caution I first headed to Exit 308 and began communicating with James Spann via his Skywatcher IM conference. It soon became evident by listening to Spann and Jason Simpson on FM 97.3, as well as looking at the sky and the radar on my laptop, that it would be safe to drive two miles further north to exit 310.

From this point I began photographing and taking video of a very impressive wall cloud and beaver tail inflow cloud northwest of Cullman. This storm was clearly rotating and occasionally producing cloud to ground lightning. It was amazing to behold. I followed it to the northeast. I remained to the southeast of the storm as I drove northeast through Cullman County on highway 157 and then highway 69.

I entered Marshall County at Arab and continued all the way to Guntersville Lake. I stopped there and took video and photos of the storm as it passed about 6-10 miles northwest to northeast of my location. I learned today that the storm produced two small EF0 tornadoes while I observed it 6-10 miles away. Although I could clearly see the rotation, the wall cloud and tornado were wrapped in rain. I did see an increase in cloud to ground lightning output that probably coincided with the tornado touchdowns.

I was careful as I drove, but I must admit I spent a lot of time glancing out of my side window or out of the left side of my windshield to my northwest. As I drove through Cullman, Fairview, Baileyton, Joppa, Arab, and on to Guntersville Lake, I saw a wall cloud the whole way. The only point it seemed to weaken turned out to probably be an illusion. In northeastern Cullman County, the storm was a bit further away than the rest of the route. The wall cloud was there and at times it seemed quite large. It makes me wonder if there would have been a large wedge tornado if there had been just a bit more directional shear near the surface. Thankfully, that did not happen.

I drove south out of Marshall County through the eastern side of Blount County before returning home to pick up my kids. I saw some very heavy rain and some minor flooding, but no more signs of major rotating storms. I stopped at a country gas station near Blountsville that was being run by a mother and her adult daughter. They were gracious enough to allow me to charge the battery on my laptop. The daughter told me she was a single mother of a nine year old boy who was scared of storms. My suggestion to her was to educate him as much as possible. She wanted to know how to get James Spann to speak at her son's school. I suggested that she ask his teacher to email Mr. Spann. She was financially very poor so I suggested that she take her son to the library and that they read everything they can about weather and storms.

What a day! I won't forget it soon.

That was a tornado-producing meso in Marshall County...

Red sky in morning, sailor’s warning





In honor of Dewdrop's very observant comment, I am editing this post's title and including the following quotes:

"Red sky at night, sailor's delight. Red sky in morning, sailor’s warning."

“Evening red and morning gray; two sure signs of one fine day.”

“Evening red and weather fine. Morning red, of rain’s a sign.”


“An evening gray and a morning red will send the shepherd wet to bed.”


“Like a red morn that ever yet betokened, Wreck to the seaman, tempest to the field, Sorrow to the shepherds, woe unto the birds, Gusts and foul flaws to herdmen and to herds.” - Billy
Shakespeare


“When in evening, ye say, it will be fair weather: For the sky is red. And in the morning, it will be foul weather today; for the sky is red and lowering.” Jesus - Matthew 16: 2-3


A red sky occurs when the atmosphere has many dust and moisture particles. Red wavelengths are breaking through the atmosphere, but we do not see the blue end of the spectrum well because those colors are scattered and broken up. A red sky in the morning usually indicates that there is a high water content in the atmosphere. So, rain may be on its way.
