MD 0359 CONCERNING TORNADO WATCH 78...81... FOR SOUTH-CENTRAL OHIO
Mesoscale Discussion 0359 NWS Storm Prediction Center Norman OK 0659 PM CDT Tue Apr 02 2024 Areas affected...south-central Ohio Concerning...Tornado Watch 78...81... Valid 022359Z - 030100Z The severe weather threat for Tornado Watch 78, 81 continues. SUMMARY...The greatest strong tornado threat in watch 78 and 81 will exist across south-central Ohio this evening. DISCUSSION...A long-track supercell has become better organized in the low-levels within the last hour near the Ohio River in south-central Ohio. Recently a TDS was apparent from the ILN WSR-88D in northern Kentucky with another TDS ongoing in Adams County, Ohio as of 2355 UTC. The environment ahead of this supercell remains favorable for tornadoes with STP around 2 and no storm interference anticipated. Therefore, this supercell will pose a continued tornado threat with the potential for strong tornadoes through the evening. ..Bentley.. 04/02/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 79 TORNADO AL MS TN 022005Z - 030200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 79 NWS Storm Prediction Center Norman OK 305 PM CDT Tue Apr 2 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Northwest Alabama Northeast Mississippi Western and middle Tennessee * Effective this Tuesday afternoon and evening from 305 PM until 900 PM CDT. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Scattered damaging winds likely with isolated significant gusts to 75 mph possible Scattered large hail events to 1.5 inches in diameter possible SUMMARY...In the wake of earlier clouds/rainfall, cloud breaks are allowing destabilization across Tennessee where new storms could form this afternoon, while other storms spread northeastward from northeast Mississippi. The environment is favorable for supercells capable of producing tornadoes (including an isolated strong/EF2+ tornado or two), damaging gusts of 60-75 mph, and large hail of 1-1.5 inches in diameter. The tornado watch area is approximately along and 75 statute miles east and west of a line from 35 miles north northeast of Nashville TN to 20 miles east of Tupelo MS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 0358 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR EASTERN MISSISSIPPI...CENTRAL ALABAMA...NORTHWEST GEORGIA
Mesoscale Discussion 0358 NWS Storm Prediction Center Norman OK 0553 PM CDT Tue Apr 02 2024 Areas affected...Eastern Mississippi...Central Alabama...Northwest Georgia Concerning...Severe potential...Tornado Watch likely Valid 022253Z - 030200Z Probability of Watch Issuance...95 percent SUMMARY...Thunderstorms will become more numerous through the evening, with an increasing risk of tornadoes and damaging winds. Watch issuance is expected in the next couple of hours. DISCUSSION...A very warm/moist and moderately unstable and only weakly capped air mass is in place this evening across much of southern MS/AL, with dewpoints in the mid/upper 60s. Recent satellite/radar loops show isolate showers and thunderstorms beginning to develop in this region. Models have been consistent in the development of a strong southerly low-level jet by mid-evening, resulting in northward advection of the better moisture and strengthening low-level wind fields. Forecast soundings suggest rapid enlargement of hodographs after dark, with parameters becoming quite favorable for supercells capable of tornadoes and damaging winds. A tornado watch will be needed for parts of this region in the next couple of hours as more robust convective initiation begins. ..Hart/Guyer.. 04/02/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0354 CONCERNING HEAVY SNOW FOR PORTIONS OF EASTERN WISCONSIN AND THE WESTERN/CENTRAL UPPER PENINSULA OF MICHIGAN
Mesoscale Discussion 0354 NWS Storm Prediction Center Norman OK 0349 PM CDT Tue Apr 02 2024 Areas affected...portions of eastern Wisconsin and the western/central Upper Peninsula of Michigan Concerning...Heavy snow Valid 022049Z - 030145Z SUMMARY...Moderate to heavy snow will gradually expand in coverage over parts of WI and MI this afternoon/evening. Rates of 1-1.5 in/hour are likely within the heaviest banding along the western shores of Lake Michigan. DISCUSSION...As of 2045 UTC, regional radar and surface analysis showed a broad precipitation shield expanding north/northeastward from a deepening surface cyclone centered over far northern IL. Within this comma head structure, moderate to heavy rain has gradually transitioned to snow. While temperatures have been only marginally conducive for snow thus far, dynamic cooling and low-level cold advection should allow for a full transition to snow from west to east. Hi-res forecast guidance suggests the development of one or more mesoscale bands is likely through this evening. Likely driven by frictional convergence on the western lake shore and slantwise convection, snow rates within some of these banded structures may reach 1-1.5 in/hr. Heavy snow will continue to expand east/northeastward across eastern WI and the western UP through the afternoon and into the evening. Confidence in the highest rates will remain along the western lake shore where forcing for ascent and inland moisture advection are expected to be the strongest. However, periodic heavy snowfall with rates near 1 in/hr will remain possible across much of WI and the UP through tonight. ..Lyons.. 04/02/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 0357 CONCERNING TORNADO WATCH 78... FOR SOUTHERN AND CENTRAL OHIO...NORTHERN KENTUCKY...AND NORTHERN WEST VIRGINIA.
Mesoscale Discussion 0357 NWS Storm Prediction Center Norman OK 0515 PM CDT Tue Apr 02 2024 Areas affected...southern and central Ohio...northern Kentucky...and northern West Virginia. Concerning...Tornado Watch 78... Valid 022215Z - 022345Z The severe weather threat for Tornado Watch 78 continues. SUMMARY...A threat for all severe weather hazards will continue through the evening. DISCUSSION...Several supercells with a history of tornadoes are moving into southwest Ohio. These supercells will continue to pose a tornado threat as they move east across southern Ohio. Additional development is ongoing ahead of this activity which may also pose a tornado threat as storms mature. The 21Z ILN RAOB shows an uncapped, moderately unstable atmosphere with low-level shear favorable for tornadoes and some strong tornadoes. Expect a similar environment to spread across much of eastern and central Ohio over the next few hours as airmass recovery continues in the wake of earlier convection. In addition, winds have backed across Ohio with strong pressure falls in response to the rapidly deepening surface low near southern Lake Michigan which will continue to support a tornado threat. The greatest tornado threat is expected south of I-70 in Ohio where dewpoints of 63 to 65F and greater instability will support a greater tornado threat amid favorable low-level shear. Expansion of tornado watch 78 will be needed with an additional tornado watch likely across much of southern, eastern, and potentially northern Ohio. ..Bentley/Guyer.. 04/02/2024 ...Please see www.spc.noaa.gov for graphic product...
