The Storm Prediction Center has dropped the Moderate Risk, but the entire Mid-South is still in a Slight Risk of severe weather overnight. These types of systems are also known to generate small spin-up tornadoes that are brief and typically weak. Overnight, you need a way to be alerted to severe weather that 1) affects you, but 2) not if it doesn't (for instance, the other side of the county). Earlier thunderstorms across AR are diminishing to showers, a mini-line of storms along I-40 on the west side of the metro fell apart quickly this morning, and all is quiet in the metro as I type this about 3:30. The cap weakens some, but with no source of lift, the next several hours should remain mostly dry. However, after dark, the cold front moves closer, wind energy increases, and cooling aloft creates additional instability, resulting in thunderstorms forming or moving in from the west. After midnight, probably between 1-3am, we expect a squall line will move across the metro along or just ahead of the cold front. Following the squall line, rain and some thunder will likely continue for up to a couple of hours. StormWatch+ allows you to program multiple locations to receive instantaneous watches and warnings for when the National Weather Service issues them. Keeping you updated on all things Memphis weather-related, including forecast discussions, event recaps, and more! Severe thunderstorms have the potential to form during the afternoon hours of April 9th across a good chunk of Northern, Central, and Western Illinois.
At first look at the upper level flow, I immediately notice an area of large scale and pronounced divergence.
Looking at the H5 flow, we notice the main jet energy nosing into the area by afternoon with these series of ripples extending into Michigan. Low level flow at H85 is flooding Northern Illinois with warm and moist air during the late afternoon. At the surface, we see a low pressure system anticipated to be close to the Decorah, IA area. Will be playing it by ear if I am going to be utilized by the NWS LOT at their office for severe weather operations. About Danny NealDanny is a storm chaser from the southside of Chicago and has been chasing since 1998. Dedication: I couldn't be the man I am today without the help of my family, friends, and educators. Some of the most severe occur when a single thunderstorm affects one location for an extended time. Thunderstorms typically produce heavy rain for a brief period, anywhere from 30 minutes to an hour.
About 10 percent of thunderstorms are classified as severe – one that produces hail at least three-quarters of an inch in diameter, has winds of 58 miles per hour or higher, or produces a tornado. Lightning often strikes outside of heavy rain and may occur as far as 10 miles away from any rainfall. Most lightning deaths and injuries occur when people are caught outdoors in the summer months during the afternoon and evening.
Your chances of being struck by lightning are estimated to be 1 in 600,000, but could be reduced even further by following safety precautions. Lightning results from the buildup and discharge of electrical energy between positively and negatively charges areas.
Watch: Thunderstorms are most likely to develop on spring or summer days, but can occur year round. Minimize the Risk: Most lightning deaths and injuries occur in the summer when organized outdoor sports activities take place. Things to Avoid: If you are in a building, stay off corded phones, computers and other electrical equipment that put you in direct contact with electricity.
Helping a Lightning Strike Victim: If a person is struck by lightning, call 911 and get medical care immediately. Summary: With common sense, you can greatly increase your safety and the safety of those you are with. You can increase the chances that your pet will survive a storm by following a few simple steps: (1) Bring your pets inside - if it is not safe for you outside, it is not safe for them. Are You Ready for a Thunderstorm (PDF, 154KB) - provided by American Red Cross, NOAA, and Federal Emergency Management Agency (FEMA).


Be prepared, not scared, and know that if thunder wakes you up, we'll be hear to let you know what's happening! Picture that pot of water - in this case a clear one so you can see into it, like the one above - starting to bubble away as the heat rises under it.
The heat from the burner is instability, another necessary ingredient for storms that typically is the result of heating of near-surface air but which can also result from colder air high in the atmosphere blowing over warm (unstable) air. By dawn, most all of it will be east of the metro and moving away as drier, cooler air filters in.
It also allows you to choose the types of alerts you want to receive and will sound "wake-me-up" audio so that you can sleep in peace - but only if the locations(s) you programmed are in harm's way! I made a post on my Facebook page detailing the risk for severe weather this week and lo and behold the pattern is verifying. What happens is when the jet stream winds begin to curve back around the trough and the others continue with the mean flow, an area of void space is left over. It is hard to say with certainty, but the NAM believes we do which is evident here by all the dark areas.
Rising and descending air within a thunderstorm separates these positive and negative charges. Coaches, camp counselors and other adults must stop activities at the first roar of thunder to ensure everyone time to get to a large building or enclosed vehicle. At the first clap of thunder, go to a large building or fully enclosed vehicle and wait 30 minutes after the last clap of thunder to go back outside. The steel frame of a hard-topped vehicle provides increased protection if you are not touching metal.
We expect storms to occur after 11pm (maybe even midnight) and will last through 4am or so.
They are very hard to pick up and quickly warn for as Tornado Warnings and can lift before the warning is even issued.
Read the last paragraph of the original post below for why we believe so strongly in StormWatch+ and why it is a must-have.
Lift is the third ingredient necessary for storms, typically provided by a front, upper-level disturbance, or other mechanism that starts the air rising. Due to the strong dynamics of this potent weather system, some storms are expected to be severe. By Friday afternoon, the sun will be shining and temperatures will remain in the 60s with a gusty northwest breeze. Prepare your safe place this evening before bed in case you need to get to it quickly overnight.
Not the other side of the county, or when the sirens go off, but when the NWS has put YOU in the polygon.
Our atmosphere will be contingent on the evolution of showers and thunderstorms from the night before. I am happy about that in terms of being a good forecast, but also frightened at the possible end result.
This moisture will stream north behind the warm front and inundate the area with >60 dew points. Pronounced long wave trough with a series of short waves should kick off convection by early afternoon from S. He routinely teaches and trains others about severe and unusual weather and is considered a great resource for Northern Illinois. In the United States, an average of 300 people are injured and 80 people are killed each year by lightning. Continued heating can cause these clouds to grow vertically into towering cumulus clouds, often the first sign of a developing thunderstorm. It may take as little as less than ten minutes within a single thunderstorm, or longer than a million years, but lightning will eventually strike the same spot again and again. Although you may be injured if lightning strikes your car, you are much safer inside a vehicle than outside. A squall line will move through between 1-3am most likely and that would bring the best chance of severe to damaging wind (60-70 mph) across the region.
We expect a watch to be issued within an hour or two for the metro, most likely a Tornado Watch, even though the primary threat will be damaging wind. Today we have most of the ingredients for storms, except for a lifting mechanism, and we have a cap at about 5000'.


The main threats will be damaging wind or hail, though any storms that form in the early stages especially will pose a risk of tornadoes as well. These types of tornadoes usually are fairly brief and weak, but objects don't care if an 80 mph straight-line wind or EF-0 tornado with 80 mph wind hit them. Severe weather is progged to develop to our west Wednesday and move into the region by the overnight hours. Rising air is obviously a source of life and that mode of ascent is enough to trigger thunderstorms typically. These shortwaves coupled with divergence should give an air parcel no problem rising through the atmosphere.
Although most lightning victims survive, people struck by lightning often report a variety of long-term, debilitating symptoms. A cloud-to-ground lightning strike begins as an invisible channel of electrically charged air moving from the cloud toward the ground. This severe weather risk would mainly be in the form of large hail as elevated supercells develop and traverse the state. This doesn’t look too far fetched as there are currently low 60 dew points at the southern end of the state. Other associated dangers of thunderstorms include tornadoes, strong winds, hail, and flash flooding. When one channel nears an object on the ground, a powerful surge of electricity from the ground moves upward to the clouds and produces the visible lightning strike.
However, with a good deal of instability and plenty of moisture in place, if the cap were eroded, storms would likely erupt and could become severe fairly quickly due to the additional ingredient of atmospheric shear, or wind energy, which is also present. Have your shoes by your bed, bicycle helmets for the kids in your safe place, and photo ID close by.
If these storms are progressive, our atmosphere is due to recover rather quickly and set the stage for some dangerous weather to form. Flash flooding is responsible for more fatalities – more than 140 annually – than any other thunderstorm-associated hazard.
If the overnight storms linger and back build, they may cause just enough overturning in the atmosphere to disrupt a rather large scale outbreak. Severe weather is still probable, but it doesn’t appear the Euro has a great handle of the system. Current indications are that the atmosphere will rapidly recover, but we will not know for sure until Thursday morning. I am concerned that previous day convection will overturn the atmosphere and not foster the development of deep convection. As such, I will continue to state that everyone needs to have a plan in place in case severe weather approaches. The NAM is the slowest and strongest evolving which is generally believable given the main jet energy still holding up just off the west coast. Risks would include: destructive straight lined winds, large hail greater than golf balls, and tornadoes.
The CIPS analog is triggering a couple of high-end notable tornado days around this region so that always is a cause for concern. If wind shear remains mostly unidirectional, we may be looking at a large line of embedded supercells with wind damage and isolated tornadoes as it races across the state. There is a lot that could go wrong about the forecast, but many of the players are lining up along the sideline and ready to take the field. Three in the last 3 years that come to mind are: November 17th, 2013, June 12th, 2013, and June 30th, 2014. I am not saying that that will be the end result, but the potential is there which I want each and everyone of you to tell your friends and family to prepare and have it in the back of your mind that some very bad weather could be in the cards. It is entirely possible that nothing happens Thursday, but are you willing to take the chance?
