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...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0353 PM CDT Sun Mar 30 2025 Valid 011200Z - 071200Z Broad mid-level troughing will prevail across the central CONUS through much of week. A pronounced mid-level impulse will traverse the south-central U.S. Days 3-4 (Tuesday-Wednesday), resulting in surface cyclone development over the Plains. On Tuesday and Wednesday afternoon, downslope and isallobaric westerly surface flow will support critically dry and windy conditions across the southern High Plains, with rapid wildfire-spread potential likely. Through the remainder of the week, dry and occasionally breezy conditions will exist across the southern High Plains as surface lee troughing persists, before a cold front surges across the southern CONUS by the weekend. ...Days 3-4 (Tuesday-Wednesday) - Southern High Plains... An 80 kt mid-level jet streak will overspread the southern Rockies, supporting the development of a 986 mb surface cyclone over Kansas, with a strong westerly surface wind field overspreading the southern High Plains. Dangerous wildfire-spread conditions will be most prevalent on Tuesday, where broad Critical probabilities are in place. High-end Critical meteorological surface conditions (i.e. 25-35 mph sustained westerly surface winds coinciding with 10-15 percent RH) will become common west of a dryline associated with the surface low. Locally Extremely Critical conditions are possible. On Wednesday, Critically dry and windy conditions will persist across New Mexico into far western Texas, where 70% Critical highlights remain in place. Fuels are receptive to wildfire spread across portions of New Mexico into western Texas. The most dangerous wildfire-spread potential will exist with fuel beds that are experiencing appreciable fuel loading. ..Squitieri.. 03/30/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 0301 CONCERNING TORNADO WATCH 70...71... FOR PORTIONS OF EASTERN ILLINOIS INTO CENTRAL/NORTHERN INDIANA AND SOUTHWEST LOWER MICHIGAN

Valid 301905Z - 302100Z The severe weather threat for Tornado Watch 70, 71 continues. SUMMARY...There is an increasing risk for severe wind gusts in central/northern Indiana and southern Lower Michigan. DISCUSSION...An organized line of storms continues to move northeast in parts of eastern Illinois. Several measured and estimated severe gusts occurred in the Champaign, IL vicinity recently. KILX radar shows strong outbound winds within this line. With continued surface heating of mostly clear/partly cloudy skies in Indiana and forcing from the shortwave trough, the potential for severe wind gusts should continue through the afternoon. Low-level shear is not overly strong per downstream VAD data, but QLCS tornadoes remain possible. The greatest potential for a tornado (and large hail) would likely exist on the southern flank of the line where storms may remain more discrete. ..Wendt.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0303 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR THE NORTHERN GULF COAST
Mesoscale Discussion 0303 NWS Storm Prediction Center Norman OK 0209 PM CDT Sun Mar 30 2025 Areas affected...The northern Gulf Coast Concerning...Severe potential...Watch unlikely Valid 301909Z - 302115Z Probability of Watch Issuance...20 percent SUMMARY...The potential for brief tornadoes may continue through the late afternoon. DISCUSSION...Over the past several hours, training convection has been continually developing along the northern Gulf Coast along a outflow-reinforced marine boundary. Although a consolidated outflow boundary is slowly developing per regional radar imagery, steady influx of high low-level theta-e air off the Gulf should promote further thunderstorm development through the diurnal heating maximum. Weakly veering winds through the lowest 2 km (best sampled by the KMOB VWP) is supporting sufficient low-level helicity for brief mesocyclone development with an attendant tornado risk. This potential has already been realized at least once based on a recent TDS evident across far southeast MS. Until the sea breeze weakens early this evening, strong updrafts with an attendant brief tornado threat may continue to develop on the southern periphery of the marine/outflow boundary. Given the localized nature of the threat watch issuance is not anticipated. ..Moore/Smith.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MOB...JAN...LIX...

Valid 301927Z - 302100Z The severe weather threat for Tornado Watch 70 continues. SUMMARY...Supercells moving into southern Illinois will pose a threat for tornadoes (possibly strong) and large to very-large hail. DISCUSSION...Storms in and moving into southern Illinois have so far remained discrete. Regional VAD data suggest that this region remains favorable for low-level rotation in supercells. As long as storms remain discrete, which is not certain given the cold front moving southeastward, there will be a threat for a tornado (possibly strong) and large to very-large hail. ..Wendt.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0305 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR SOUTHERN LOWER MICHIGAN...NORTHWEST OHIO
Mesoscale Discussion 0305 NWS Storm Prediction Center Norman OK 0249 PM CDT Sun Mar 30 2025 Areas affected...Southern Lower Michigan...Northwest Ohio Concerning...Severe potential...Tornado Watch likely Valid 301949Z - 302145Z Probability of Watch Issuance...95 percent SUMMARY...An organized line of storms with a history of 60-85 mph wind gusts will continue into western Ohio and southern Lower Michigan. Risk for damaging winds will continue with more isolated/uncertain threats for large hail and tornadoes. DISCUSSION...An organized line of fast-moving storms continues northeastward through central/northern Indiana. Modest destabilization continues ahead of this line into portions of western Ohio and southern Lower Michigan. Given the organization of this line, potential for severe/damaging gusts will remain even as buoyancy tends to wane north and east. This line of storms has a history of producing wind gusts of 60-85 mph. Damaging winds will likely remain the primary risk. Isolated large hail could occur, but storm mode will mitigate that risk. Likewise, storm mode is also not optimal for tornadoes. Regional VAD winds and RAP forecast soundings do suggest some QLCS tornado risk will exist, but this risk diminishes with eastward extent. One or more watches will need to be considered for portions of western Ohio and southern Lower Michigan by 21Z. ..Wendt/Smith.. 03/30/2025 ...Please see www.spc.noaa.gov for graphic product...
