MD 0307 CONCERNING TORNADO WATCH 72... FOR MID MISSISSIPPI VALLEY
Mesoscale Discussion 0307 NWS Storm Prediction Center Norman OK 0520 PM CDT Sun Mar 30 2025 Areas affected...Mid Mississippi Valley Concerning...Tornado Watch 72... Valid 302220Z - 310015Z The severe weather threat for Tornado Watch 72 continues. SUMMARY...A severe threat will continue across the mid Mississippi Valley through early to mid evening. Very large hail, severe wind gusts and tornadoes will be possible. Weather watch issuance will eventually be needed to the east of the current watches over parts of central Kentucky and western Tennessee. DISCUSSION...The latest WSR-88D radar imagery from Paducah shows several supercells ongoing along a corridor from far northern Arkansas northeastward into southern Illinois. These severe storms are located to the west of an axis of moderate instability where the RAP is analyzing MLCAPE in the 2000 to 3000 J/kg range. In addition, the Paducah WSR-88D VWP has 0-6 km shear around 55 knots with pronounced directional shear in the lowest 2 km AGL. This shear profile will be favorable for severe storms, and continued supercell development. The steepest mid-level lapse rates are located over far southeast Missouri and northeast Arkansas, where supercells could produce hailstones greater than 2 inches in diameter. Over the next couple of hours, a 40 to 50 knot low-level jet will increase in strength over western Tennessee and western Kentucky. This will make low-level shear increasingly favorable for tornadoes, especially as the supercells interact with the low-level jet. Eventually, a nearly continuous line of storms will become organized into a linear MCS. As this line moves eastward into areas near and to the east of the Mississippi River, the wind-damage potential is expected to increase and wind gusts above 70 mph will become likely along and just ahead of the more intense parts of the line. ..Broyles.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0308 CONCERNING TORNADO WATCH 70... FOR SOUTHERN INDIANA INTO SOUTHWEST OHIO
Mesoscale Discussion 0308 NWS Storm Prediction Center Norman OK 0535 PM CDT Sun Mar 30 2025 Areas affected...Southern Indiana into southwest Ohio Concerning...Tornado Watch 70... Valid 302235Z - 310030Z The severe weather threat for Tornado Watch 70 continues. SUMMARY...The severe risk will continue spreading eastward across southern Indiana (in Tornado Watch 70) and eventually into Southwest Ohio . A downstream watch will be issued by 23Z. DISCUSSION...A northeast/southwest-oriented QLCS is tracking eastward across central and southern Indiana at around 40 kt. Along the southern portion of the line, an organized line segment is more favorably oriented to around 50 kt of southwesterly deep-layer shear, and this activity has produced severe wind gusts up to 70 mph. Given the organized linear mode, severe gusts upwards of 70-80 mph will be the primary concern. However, some deeper/rotating updrafts embedded in the line, along with isolated/discrete cell development immediately ahead of the line, will be capable of producing hail up to 1.75 inches and a couple tornadoes. With time, these storms will continue eastward into southwest OH, where a continued linear mode should favor primarily severe wind gusts. While severe wind is the primary concern, a couple embedded tornadoes will also be be possible, especially given a stronger low-level jet and larger clockwise curved hodographs (around 200 m2/s2 effective SRH) into southwest OH. A downstream watch will be issued by 23Z. ..Weinman/Mosier.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ILN...LMK...IND...

MD 0302 CONCERNING WINTER MIXED PRECIPITATION FOR NORTHERN WISCONSIN INTO THE UPPER PENINSULA OF MICHIGAN
Mesoscale Discussion 0302 NWS Storm Prediction Center Norman OK 0207 PM CDT Sun Mar 30 2025 Areas affected...Northern Wisconsin into the Upper Peninsula of Michigan Concerning...Winter mixed precipitation Valid 301907Z - 310000Z SUMMARY...Another round of moderate to heavy snow and sleet/freezing rain is expected to spread across northern Wisconsin into the Upper Peninsula of Michigan. DISCUSSION...Recent surface observations across northern WI report a mix of sleet/freezing rain to the west/northwest of the Green Bay, WI area and light to moderate snow across northern/northwest WI. This precipitation is expected to increase in coverage and intensity as it spread northeastward through early evening amid strengthening warm advection between 925-850 mb and within the 700 mb deformation zone. The steady warm advection will also maintain a warm nose between 1-2 km AGL that will continue to promote sleet and freezing rain through the afternoon. Latest guidance continues to suggest that freezing rain rates between 0.05 to 0.1 inch/hour are probable across far northeast WI into the southern areas of the U.P. A gradual eastward shift of the warm nose is anticipated through late afternoon, which should result in sub-freezing temperatures throughout the column. This thermodynamic trend, coupled with organized precipitation banding, should promote areas of moderate to heavy snowfall rates between 1-2 inch/hour across northern WI into western parts of the U.P. ..Moore.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product...
