SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1112 PM CST Tue Mar 04 2025 Valid 061200Z - 071200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorm activity is possible across parts of central California and the Great Basin into the Southern Rockies Thursday into Thursday evening, but the risk for severe thunderstorms appears neglible. ...Discussion... The center of a broad and deep, occluding cyclone is forecast to progress across the lower Great Lakes into southwestern Quebec by 12Z Thursday, when a significant trailing cold front may be offshore all the Atlantic Seaboard but perhaps eastern portions of New England. It appears that the southwestern flank of this front will be in the process of stalling and weakening across the western Gulf Basin, and models indicate that the boundary layer may undergo substantive modification across the southwestern Gulf toward the lower Texas coast vicinity late Thursday through Thursday night. This may be accompanied by weak inland boundary-layer moisture return beneath warm and capping elevated mixed-layer air across the southern Great Plains, as renewed cyclogenesis occurs to the lee of the Colorado Rockies. Within and beneath a generally confluent mid-level regime to the east of the Rockies, the cyclone, and supporting mid-level short wave perturbation emerging from larger-scale troughing advancing inland of the Pacific coast, are likely to weaken while progressing eastward through the central Great Plains Thursday night into early Friday. Trailing the lead short wave, models indicate that a more prominent short wave trough will dig inland across central/southern California, and into the lower Colorado Valley by 12Z Friday. ...Central California through southern Great Basin/Rockies... A swath of stronger mid-level cooling overspreading the region in association with the short wave developments is likely to contribute to weak destabilization with daytime heating. It appears that this will become sufficient to support scattered weak afternoon and evening thunderstorm activity, aided by areas of dynamic and orographic forcing for ascent. ...Cape Cod vicinity... Forecast soundings, perhaps most notably the NAM, suggest that lift associated with frontal forcing and/or pre-frontal low-level warm advection may still be contributing to elevated convective development capable of producing lightning around 12Z Thursday, before spreading away from the coast by mid/late morning. ..Kerr.. 03/05/2025 Read more

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1148 PM CST Tue Mar 04 2025 Valid 051200Z - 061200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS THE EASTERN CAROLINAS INTO SOUTHEAST VIRGINIA... ...SUMMARY... Severe thunderstorms capable of producing scattered damaging-wind gusts and a few tornadoes are possible Wednesday across parts of the eastern Carolinas into southeast Virginia. Other strong to severe storms may occur across parts of Florida and east Georgia, and also from the Allegheny Plateau into the Mid Atlantic. ...Synopsis... An intense upper trough, initially over the MS Valley this morning, and characterized by a 500 mb jet streak of 90+ kt, will pivot east across the eastern U.S. through the period. Through the morning and early afternoon hours, a southerly low level jet greater than 60 kt will overspread the Southeast coastal vicinity into the Mid-Atlantic and lower Great Lakes regions. At the surface, strong warm advection will transport 60s F dewpoints northward ahead of an eastward-progressing cold front from FL into southeast GA and as far north as southeast VA. Moisture will become more modest with northward extent into eastern OH/PA/western NY. The net result will be a modestly unstable airmass in the presence of intense deep-layer flow supporting a large area of strong to severe/damaging wind potential. Tornado potential also is possible, with greater potential expected from the Carolinas into southeast VA where low-level moisture will be greater. ...VA south to north FL... A QLCS is expected to be ongoing this morning, extending from western WV/VA and the western Carolinas into southeast GA and north FL. Diurnal heating will be limited, and low-level lapse rates will remain poor. This will pose some challenge for purely surface-based convection. Nevertheless, very strong large-scale ascent amid intense wind profiles will likely be sufficient for swaths of damaging gusts. Furthermore, forecast soundings indicate the presence of midlevel dry air just ahead of the eastward-advancing QLCS across the Carolinas and VA. This could further aid in some downward transport of stronger winds. Where 60s F dewpoints are achieved, QLCS tornadoes also will be possible, especially if backed low-level flow can be maintained to further enhance low-level SRH. While instability will likely be greater with southward extent, large-scale ascent will be lifting north of the GA/FL vicinity. Strong deep-layer flow will still be in place, and coupled with modest instability, this should result in some continued organized convection capable of strong to severe gusts. ...Lower Great Lakes Vicinity... Further north, instability will be quite limited given a cooler boundary layer and dewpoints generally in the mid 40s to mid 50s F. However, cold temperatures aloft will result in steep midlevel lapse rates and foster MUCAPE values up to 500 J/kg. Additionally, closer to the surface low, vertically veering wind profiles with effective shear values near 40 kt, will support isolated low-topped supercells and perhaps linear segments. Strong to severe gusts, isolated hail and perhaps a tornado will be possible with this activity this afternoon. ..Leitman/Squitieri.. 03/05/2025 Read more

MD 0140 CONCERNING BLIZZARD FOR PORTIONS OF EXTREME EASTERN NEBRASKA INTO WESTERN IOWA
Mesoscale Discussion 0140 NWS Storm Prediction Center Norman OK 0720 PM CST Tue Mar 04 2025 Areas affected...portions of extreme eastern Nebraska into western Iowa Concerning...Blizzard Valid 050120Z - 050515Z SUMMARY...Blizzard conditions are expected to become more common through early tonight. Sustained winds over 40 mph are possible amid intermittent bouts of moderate to heavy snow and quarter-mile visibilities. DISCUSSION...A surface low, analyzed just east-northeast of the Kansas City metropolitan area, continues to drift northeast while gradually deepening. The northwest quadrant of this low continues to overspread portions of extreme eastern NE into western IA, where deep-layer cold-air advection is supporting the transition from rain to snow. Surface observations and correlation coefficient data from KOAX NEXRAD radar indicate the rain/snow transition line roughly from Crawford to Fremont Counties in IA, with surface northwesterly winds intensifying to over 30 kts west of this line. The expectation is for sustained surface winds to reach 40 mph in spots, with increasing snowfall rates (perhaps briefly reaching 1 inch/hour) over the next few hours. Such conditions may reduce visibility to around a quarter mile or less. Additionally, the latest high-resolution guidance consensus suggests that blizzard conditions are most likely across western IA in the 02-08Z time frame. ..Squitieri.. 03/05/2025 ...Please see www.spc.noaa.gov for graphic product...

Severe thunderstorms with a threat for damaging winds and a few tornadoes will continue into the evening and overnight hours across portions of the Southeast. ...Southeast... A strongly forcing QLCS will continue to move across portions of southern MS/southeast LA and AL this evening, shifting east into the FL Panhandle and GA overnight. While instability will remain modest, very strong deep-layer flow fields will support robust damaging wind potential. Likewise, strong low-level shear, as evident in regional VWP data indicates potential for a few tornadoes. Tornado potential will mostly be confined the Gulf coast into southern AL where at least some potential for surface-based convection exists amid dewpoints in the low 60s F. Otherwise, strong to damaging gusts will be possible near the QLCS, with diminishing potential with northward extent as instability wanes toward northern AL/TN/KY. ..Leitman.. 03/05/2025 Read more

Moderate to heavy snowfall rates may occur with northwesterly surface winds sustaining over 40 mph, perhaps gusting to 70 mph. Visibility may drop to a quarter mile in spots. DISCUSSION...A surface low along the KS/MO border continues to deepen while shifting towards the Great Lakes, promoting a broad, intense northwesterly surface wind field over parts of the central Plains. Surface observations show northwesterly surface winds sustaining to 40 mph at times over parts of central/eastern NE, where measured gusts have exceeded 65 mph. In tandem with these intense winds are developing snow-bands, as surface-700 mb cold-air advection continues to cool the column to temperatures below freezing. The surface low should continue to intensify through the evening as snowfall rates gradually increase. The current expectation is for blizzard conditions and reduced visibility to gradually become more common through the evening. ..Squitieri.. 03/04/2025 ...Please see www.spc.noaa.gov for graphic product...

Valid 042336Z - 050130Z The severe weather threat for Tornado Watch 21 continues. SUMMARY...Severe threat will spread southeast this evening. Damaging winds can be expected, along with some risk for a few tornadoes. DISCUSSION...Intense mid-level height falls will spread across the mid-Mississippi valley this evening, with lesser, but significant forcing extending south across the lower MS Valley ahead of a strong short-wave trough. Long-lived, organized squall line is propagating southeast ahead of this feature, and currently extends from east-central MS into southeast LA. Higher boundary-layer moisture has struggled to move appreciably inland with mid 60s surface dew points having advanced into Jones County MS, roughly 70 mi north of the Coast. This is about the northern extent of modest buoyancy, and the greatest instability should hold along/near the Gulf Coast much of the evening. Very strong wind profiles continue to favor organized convection and damaging winds are expected with this linear MCS. Until/unless more discrete cells form ahead of the line, any tornado risk should be with embedded supercells. ..Darrow.. 03/04/2025 ...Please see www.spc.noaa.gov for graphic product...
