Severe Weather Impacting the West, Midwest, Possibly Northeast

3/17/2012 — Severe weather forming out west — preparations should be made now

Posted on March 18, 2012

watch the update here:


Today was a somewhat heavy day for the midwest — damaging winds, nickel sized hail , excessive lightning … Missouri, Illinois, Indiana have received the brunt of this first SMALL system.

Coming out west — a very large low pressure system — pushing its way south near the Border of Mexico/California — pressing eastward eventually.. then northeast ..

College of Dupage GOES infrared satellite – northern hemisphere view :

This will draw the southern flow of warm moist air up from the south — mixing the cold air from the north — cold enough to produce a large winter weather advisory out west in CA, OR, WA, ID, NV, UT, CO.

When the system finally heads east (after the above mentioned western states).. it will give us extreme severe weather in Texas, Oklahoma, Kansas, Missouri, Arkansas, (possibly nebraska), Lousiana, Mississippi , Alabama, Tennessee, Kentucky, Illinois, Ohio …. eventually the east coast and south east as well…

Expect severe damaging winds.. large hail.. and tornadoes in several of the above mentioned states.. if not ALL the above mentioned states.  Only a few may be spared some kind of severe weather.  Most will get the hail and damaging winds for sure — lets HOPE few get tornadoes.

Time for preparation is now… in case of loss of home, property, or in case of injury — make these plans and know them well… make sure your friends/family/loved ones also know the plan.

Power outage, loss of shelter, loss of transportation, water cut off etc.. these are all common results of severe weather.. sometimes entire communities are wiped out (as was the case 3 weeks ago in the midwest).

FEMA turned DOWN disaster coverage for the people of Illinois (who lost entire towns)… so if youre looking for help AFTER a storm.. the only help you’ll be getting will be from local government, family, or friends….. so have insurance if you can afford it.. if you rent.. get that renters insurance.. make sure it covers severe weather and earthquakes !!!

much love, be safe, and heed the warnings if they are issued for your area— but don’t RELY on the warnings.. if you see these storms forming… best to look for yourself to find out whats going on.. I’ve assembled several links you can use to monitor this current and coming outbreak personally…


Wind & The Shape of Trees

Leonardo da Vinci's tree rule may be explained by wind

( — More than 500 years ago, Leonardo da Vinci observed a particular relationship between the size of a tree’s trunk and the size of its branches. Specifically, the combined cross-sectional areas of a tree’s daughter branches are equal to the cross-sectional area of the mother branch. However, da Vinci didn’t know why tree branching followed this rule, and few explanations have been proposed since then. But now in a new study, physicist Christophe Eloy from Aix-Marseille University in Aix-en-Provence, France, has shown that this tree structure may be optimal for enabling trees to resist wind-induced stresses.

In his study, which is published in a recent issue of , Eloy explains that Leonardo’s rule is so natural to the eye that it is often used in computer-generated trees. Although researchers have previously proposed explanations for the rule based on hydraulics or structure, none of these explanations have been fully convincing. For instance, the hydraulic explanation called the “pipe model” proposes that the branching proportions have to do with the way that vascular vessels connect the tree’s roots to its leaves to provide water and nutrients. But since vascular vessels account for as little as 5% of the branch cross section (for large trunks in some tree species), it seems unlikely that they would govern the tree’s entire architecture.

“The usual textbook explanation for Leonardo’s rule (and, more generally, for the relation between branch diameters) involves hydraulic considerations,” Eloy said. “My study shows that an alternative explanation can be given by considering external loads, such as wind-induced forces.”

Eloy has proposed that Leonardo’s rule is a consequence of trees adapting their growth to optimally resist wind-induced stresses. It’s well-known that plants can alter their growth patterns in response to mechanical sensation, such as wind. The phenomenon, called “thigmomorphogenesis,” means that wind can influence the trunk and branch diameters of a tree as its growing. The underlying cellular mechanisms of this phenomenon are largely unknown.

Building on this line of thinking, Eloy used two models to predict the probability of a fracture at a certain point in a tree due to strong winds. He found that, when the probability of fracture is the same everywhere on the tree, so that each part bears the stress equally, Leonardo’s rule is recovered. He also showed that the diameters of each branch on a tree can be calculated by knowing the parameters of a simple tree skeleton.

Although some of the most common tree species, such as maples and oaks, seem to follow Leonardo’s rule, there are many species that don’t follow the rule, and many more that scientists have yet to analyze.

“Actually, Leonardo’s rule has not been assessed for that many species,” Eloy said. “So far, it seems to be hold for about 10 species. The problem is that it takes a lot of time to measure a single tree, which has thousands of branches, and the data are usually very scattered. Besides, some species clearly do not satisfy Leonardo’s rule, such as baobabs, koas, and most bushes.”

The finding that trees seem to follow Leonardo’s  when adapting their growth to tolerate wind-induced stresses could have applications both in nature and technology.

“It has obvious applications to the forestry industry to calculate the yields of tree stands and to evaluate the risks of breakage during storms,” Eloy said. “It could also be applied to manmade branching structures such as antennas.”

He added that there is still much more to understand about tree design, including the self-similarity shared by large trunks and smaller branches.

“I am still working on this subject, in particular to try to relate growth to external loads,” he said. “In other words, I would like to understand the dynamical growth mechanisms that lead to the intricate fractal structures of.”

Nor’easter on the Way

Nor’easter takes aim at the Eastern United States this week

( – The weather pattern is changing for the Eastern United States as a strong surface low should ride the area, providing gusty winds and pounding rainfall.

On the backside of the system, say in Minnesota and Wisconsin, we probably will see those areas get light snowfall, but the ground is still warm so accumulations or sustained accumulations will not be expected.

This is not a blizzard producing Nor’easter so areas in the Northeast due not have to worry about being buried in feet of snow like with deep-winter style Nor’easters.

Areas in the Southern Gulf States (including Florida) will need to be monitored for severe weather as tropical moisture from a developing system near the Yucatan streams northward to meet the surface low and frontal zone by Tuesday through Thursday of this week.


Phoenix Haboob

Phoenix Dust Storm: Arizona Hit With Monstrous ‘Haboob’ (PHOTOS/VIDEO)

First Posted: 07/6/11 09:22 AM ET Updated: 07/6/11 05:25 PM ET

monstrous dust storm roared through Phoenix, Arizona on Tuesday night, delaying flights and causing power outages for thousands of people.

The AP reports that the massive dust cloud, also known as a “haboob,” was around 5,000 feet when itarrived in Phoenix, but radar data reveals that it reached heights anywhere from 8,000 to 10,000 feet high prior. The storm appeared to be around 50 miles wide in some areas, KSAZ-TV reported.

The dust storm originated in Tucson, and was a part of Arizona’s monsoon season.

According to CNN, the dust storm prompted the Federal Aviation Administration to issue a ground stop on flights at Phoenix’s Sky Harbor Airport for about an hour and 15 minutes. At its peak, the storm left 10,000 customers without power, Jenna Shaver of the Arizona Public Service told CNN.

This Landsat 5 satellite image of the Wallow North Fire in east central Arizona was taken on June 15, 2011 at 19:54:23 Zulu (3:54 p.m. EDT). This false-colored image uses a 7, 4, 2 band combination and shows the burn scar in red the fire ongoing in really bright red, vegetation is green, smoke is blue and bare ground is tan.

The raging Wallow Fire that has burned nearly 500,000 acres of Arizona is slowly being contained by firefighters with some helpfrom eyes in the sky.

About 33 percent of the fire is contained, but high winds that can cause wildfires to spread could tax those containment efforts. Emergency managers and responders are using satellite data from a variety of instruments to plan their firefighting containment strategies and mitigation efforts once the fires are out.
