WW 57 TORNADO IA IL IN 191715Z - 200200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 57 NWS Storm Prediction Center Norman OK 1215 PM CDT Wed Mar 19 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Far Eastern Iowa Northern and Central Illinois Western Indiana * Effective this Wednesday afternoon and evening from 1215 PM until 900 PM CDT. * Primary threats include... A few tornadoes and a couple intense tornadoes possible Scattered damaging wind gusts to 70 mph possible Scattered large hail events to 1.5 inches in diameter possible SUMMARY...Scattered supercell thunderstorms are expected to develop northeast through the early evening. These storms may produce a few tornadoes, damaging gusts, and hail. The tornado watch area is approximately along and 90 statute miles east and west of a line from 25 miles west northwest of Marseilles IL to 60 miles east of Salem IL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). 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. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 400. Mean storm motion vector 22035. ...Leitman Read more

MD 0249 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR WESTERN AND MIDDLE TENNESSEE INTO NORTHERN MISSISSIPPI AND NORTHWEST ALABAMA
Mesoscale Discussion 0249 NWS Storm Prediction Center Norman OK 0634 PM CDT Wed Mar 19 2025 Areas affected...Western and middle Tennessee into northern Mississippi and northwest Alabama Concerning...Severe potential...Watch unlikely Valid 192334Z - 200130Z Probability of Watch Issuance...20 percent SUMMARY...Thunderstorm development is expected between 7-9 PM CDT across western Tennessee and northern to central Mississippi with a downstream risk for severe hail and damaging winds. The risk is expected to remain sufficiently isolated to preclude watch issuance. DISCUSSION...GOES visible imagery shows gradually deepening cumulus along and just ahead of a diffuse dryline/Pacific front from western TN southward into MS. This trend is expected to continue as mid-level temperatures continue to cool with the eastward progression of the primary trough axis, resulting in improving 700-500 mb lapse rates that will be more favorable for sustained convection. This trend is already being observed further north across the lower OH River Valley, suggesting that thunderstorm development is becoming more likely for areas further south. Modest surface moisture (mid 50s dewpoints) will continue to limit overall buoyancy values (MLCAPE should be maximized around 500-750 J/kg), but wind fields over the region are supporting elongated hodographs that will promote organization of the more intense updrafts. Weak off-boundary storm motions/deep-layer shear vectors suggest that a combination of semi-discrete cells and clusters is likely later this evening as storms move into middle TN and northwest AL. Given the convective environment and trends in latest CAM guidance, a few of the more intense cells/clusters may pose a severe hail/wind threat through the late evening. ..Moore/Hart.. 03/19/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0757 PM CDT Wed Mar 19 2025 Valid 200100Z - 201200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM INDIANA INTO CENTRAL KENTUCKY AND FAR WESTERN OHIO... ...SUMMARY... Scattered severe thunderstorms remain possible this evening mainly over Indiana, parts of Kentucky and into Tennessee. ...IN into western KY... A primary line of storms stretches from central IN into western KY and TN as of 01Z, with secondary line of storms along the IL/IN border in association with the cold front. Given the loss of heating and relatively narrow zone of instability, the primary risk of damaging gusts, hail, and perhaps a brief tornado should be greatest over the next 1-2 hours, and will then wane within the 03-06Z time frame. Even so, isolated strong storms cannot be ruled out as far east as central OH and south into parts of MS and AL as the front pushes through tonight.
