Severe Storms

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

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

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

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.

MD 0142 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR FLORIDA PANHANDLE...SOUTHEAST ALABAMA...SOUTHWEST GEORGIA
Mesoscale Discussion 0142 NWS Storm Prediction Center Norman OK 1028 PM CST Tue Mar 04 2025 Areas affected...Florida Panhandle...Southeast Alabama...Southwest Georgia Concerning...Severe potential...Tornado Watch likely Valid 050428Z - 050530Z Probability of Watch Issuance...80 percent SUMMARY...New Tornado Watch appears warranted. DISCUSSION...Mid 60s surface dew points have nosed inland ahead of the squall line across the western Florida Panhandle. This air mass is providing a bit more buoyancy along southern portions of the MCS, which may enhance updraft strength and potential severe. Forecast soundings suggest near-surface based convection with 65 dew point, but lifted parcels are still likely a bit elevated. Latest buoy data suggests 67 dew point is just offshore and this may advance inland ahead of the line. Given the very strong shear, there is increasing concern for damaging winds, and perhaps a few tornadoes. New Tornado watch will likely be issued soon. ..Darrow/Guyer.. 03/05/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TAE...BMX...MOB...
