  1. The April 3-4, 1974 Super Outbreak is the second largest outbreak of tornadoes on record and holds the record for the most F5 tornadoes on a single day. At least 148 tornadoes developed during the super outbreak, touching down in 13 states, killing around 335 people, and causing approximately $600 million in damages. The first tornado was reported around 9:30 am CDT on April 3 in Indiana, and the final tornado occurred around 8 am CDT on April 4 in North Carolina, with the peak occurring between 2 pm and 10 pm on April 3. Dozens of noteworthy tornadoes occurred in a very short amount of time, making the impact even more severe and the recovery process more daunting. Many of the tornadoes moved at speeds exceeding 50 mph, and two in particular followed identical paths, causing more than half of the recorded deaths from the outbreak and striking many communities twice in under an hour. States across the Midwest experienced colossal loss: Ohio, India, Kentucky, Tennessee, and Alabama had about 200 fatalities and over $80 million in damages between them as a result of the tornadoes, one of which was witnessed by NWS employees. In the aftermath of this catastrophe, it was clear that changes needed to be made, particularly in the areas of public education and awareness. Outside of the NWS, local broadcasters learned they could stay on the air beyond normal operating hours during weather emergencies, and local principalities began to utilize their Emergency Broadcast Systems far more frequently and effectively. NOAA Weather Radio (NWR) proved to be an effective means of disseminating alerts in the larger metropolitan areas during the outbreak, and as a result, NWR was expanded. https://vlab.noaa.gov/web/nws-heritage/-/the-april-1974-super-outbreak-of-tornadoes
  2. Valleys of Ohio and Tennessee into the Appalachians... As the upper trough continues, there should be some serious threat over portions of the OH/TN Valleys and into the Appalachians on Tuesday. The precise location of the primary surface low and the evolution of the upper trough remain somewhat uncertain, but there is enough confidence in a somewhat narrow corridor over these regions to add a 15% severe area for Tuesday. A cold front approaching eastward should be preceded by rich, low-level moisture. It appears likely that convection may redevelop and/or intensify by Tuesday afternoon. Given the predicted severity of a low-level jet concentrated over portions of the region, strong deep-layer shear and mild instability should be sufficient for organized severe convection, offering some concern for damaging winds and maybe tornadoes.
  3. Thursday's storm was a classic example of a supercell. Look at this 3-D image of the storm, and compare its features to a textbook schematic. It dropped very large hail and produced a long-track EF-2 tornado that crossed the Ohio River three times.

  5. URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 44 NWS Storm Prediction Center Norman OK 415 PM CDT Thu Mar 14 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of much of Indiana western and central Ohio * Effective this Thursday afternoon and evening from 415 PM until 1100 PM CDT. * Primary threats include... A few tornadoes likely Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Strong/severe thunderstorm development is expected over the next couple of hours across much of Indiana, and spreading into western Ohio thereafter. Along with large hail and locally damaging wind gusts, a few tornadoes will also be possible into this evening. The tornado watch area is approximately along and 65 statute miles north and south of a line from 25 miles north northwest of Terre Haute IN to 35 miles north northeast of Columbus OH. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings.
  6. @Kentucky Windage The dew points are forecast to rise this evening into Friday morning.
  7. The major danger window for Kentucky will be later this evening and throughout the night. This is illustrated in the lightning flash intensity map below. It covers from 2:00 PM Thursday to 5:00 AM Friday.
  8. URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 41 NWS Storm Prediction Center Norman OK 1050 AM EDT Thu Mar 14 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of much of Indiana far northern Kentucky parts of western Ohio * Effective this Thursday morning and afternoon from 1050 AM until 400 PM EDT. * Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible A tornado or two possible SUMMARY...A broken band of thunderstorms is expected to continue intensifying this morning and into this afternoon, as it moves across Indiana and vicinity. Large hail and damaging winds will be possible, along with potential for a couple of brief tornadoes associated with stronger cells within the broader line of storms. The severe thunderstorm watch area is approximately along and 70 statute miles east and west of a line from 60 miles north northwest of Muncie IN to 50 miles south of Bloomington IN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes.
  9. Since this morning, there is a greater chance of severe weather. The level 2 Slight Risk area has been extended by the Storm Prediction Center to about the I-65 corridor. Additionally, the Cincinnati/NKY region is included by extending it along the Ohio River. Thunderstorm bands are still lingering over parts of Illinois and Missouri. As it moves quickly east-northeastward this morning, this activity could continue to present isolated chances for one or more embedded tornadoes as well as intermittent severe gusts. Threats from severe gusts and tornadoes can concentrate along the warm front. However, the early-morning instability minimum in the boundary layer may potentially mitigate the catastrophic danger locally. In certain areas of IN and possibly KY, the combined complex may be re-intensifying to some extent at this time. An additional possible round of convection this afternoon and tonight appears to pose a conditionally serious threat for tornadoes, big to very large hail, and severe wind. Long-lasting supercells and bending clusters may develop in areas of the atmosphere that are not disturbed by outside influences.
  10. I just received this from the National Weather Service-Louisville office:
