Nashville severe wx full#

I will have a post early next week talking about weather safety in full detail. Here’s just general rules about severe weather safety. THE PUBLIC SHOULD BE STRONGLY ADVISEDīecause of such a high elevated threat, let’s have a quick review on safety: THIS EVENT COULD BE ONE OF THE GREATER IMPACTĮVENTS IN THE PAST FEW YEARS. YESTERDAY…PROBABLY THE BIGGEST OUTBREAK OF TORNADOES SINCEĪPRIL 27, 2011. WIDESPREAD AND SUBSTANTIAL THAN THE SEVERE THREAT WE HAD SPC CONTINUES TO POST A MODERATE RISK FOR STRONG LONG TRACK TORNADOES…DAMAGING WINDS AND LARGE Reminds me of the SEC Men’s Tournament in Atlanta back in 2008 when the Atlanta tornado pushed through:Ī BIG SEVERE WX OUTBREAK IS EXPECTED FOR MID TNįRIDAY. NOTE: The SEC Tournament in women’s basketball is being played today. Here’s strong wording from the National Weather Service in Nashville, TN. Image Credit: WxCaster (Earl Barker’s Model Page) Note: Look at how the high STP values correspond with the high risk areas: Anything over a 1 or in yellow is considered significant for tornado development. Take a look at the STP values for this evening. Anything over a 1 is considered significant. The STP, or Significant tornado parameter measures all of the above ingredients mentioned above and puts out areas likely to see signifcant tornadoes. There will be plenty of moisture to work with, so all of the ingredients are being put together for a significant outbreak of severe storms and tornadoes. Areas could exceed 2000 joules per kilogram, which is fairly high.

Instability, which measures how stable the atmosphere becomes, is very high for this time of year across the risk areas. High helicity values indicate areas of strong tornado development. Helicity levels, or the spin in the atmosphere is very high too. Wind shear is very high, which contributes to sustaining thunderstorms. South and ahead of the front, unusual warm air for this time of year will provide the trigger to see severe thunderstorms capable of producing strong tornadoes. Behind this front, temperatures are very cold with highs expected to climb in the 40’s across Missouri and Iowa. Image Credit: NWSĪ strong area of low pressure will develop and move northeast. A forecast by the NWS showing the strong area of low pressure moving in this afternoon. The hatched area shows a 10% or greater probability of two inch diameter hail or larger within 25 miles of a point. In this image, the percentages represent the probability of one inch diameter hail or larger within 25 miles of a point. The hatched area shows a 10% or greater probability of wind gusts 65 knots (75 mph or hurricane force) or greater within 25 miles of a point. In this image, the percentages represent the probability of damaging thunderstorm winds or wind gusts of 50 knots (60 mph) or higher within 25 miles of a point.

A 30% hatched area is VERY significant!!!! Areas that are hatched show a 10% or greater probability of EF2 – EF5 tornadoes within 25 miles of a point. In this image, the numbers/percentages show the probability of a tornado within 25 miles of a point. This is a very serious situation for Kentucky and north/central Tennessee: High risk areas are extremely rare and are typically issued once or twice a year. Here is the outlook for today’s severe weather. The “risk” areas are just one of many products they create that outline the risks of severe weather across the nation. The Storm Prediction Center, also called the SPC, is an office that predicts and outlooks severe weather across the United States.

I will also have a few safety rules at the end that you and your family can follow in case a severe storm moves through your area. In this post, I am going to explain the ingredients that are coming together to see a significant severe weather outbreak. These storms will be capable of producing large hail, strong winds over 60 miles per hour, and frequent cloud to ground lightning. Strong tornadoes cannot be ruled out across northern Mississippi, central and northern Alabama, and across the Ohio River Valley. There is an elevated risk for strong, long lived tornadoes across central Tennessee and Kentucky. I mentioned how the storms that develop on March 2-3, 2012 will be more potent than the storms that pushed through February 28 and 29, 2012. In my previous post on EarthSky, I mentioned the chances for severe for this upcoming weekend.
