Severe Storms

SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0125 PM CST Mon Mar 03 2025 Valid 051200Z - 061200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE MID ATLANTIC INTO PARTS OF THE CAROLINAS AND EASTERN GEORGIA... ...SUMMARY... Severe thunderstorms capable of producing damaging winds and a few tornadoes are possible across parts of the southern and middle Atlantic Seaboard on Wednesday. Isolated strong to severe storms will also be possible from the eastern Ohio Valley into parts of Pennsylvania. ...Synopsis... A deep mid/upper-level shortwave trough is forecast to move across the eastern CONUS on Wednesday, as an embedded occluding cyclone moves northeastward toward the lower Great Lakes region. A remnant QLCS may be ongoing Wednesday morning from the Florida Panhandle and northern peninsula into the Carolina Piedmont region. Low-level moisture will continue to stream northward within the warm sector of the cyclone, with mid 50s to low 60s F dewpoints potentially reaching portions of the Carolinas and Mid Atlantic, and somewhat less robust moisture into parts of the Ohio Valley in advance of the primary cold front. ...Florida into the Mid Atlantic... While the QLCS that is expected to develop on D2/Tuesday may weaken overnight into early Wednesday morning, moistening in advance of the remnant QLCS could support some intensification through the day, with very strong deep-layer flow and low-level shear supporting some damaging-wind and tornado potential as the initial line moves eastward. In the wake of the initial convective line, there will be some potential for destabilization from the Carolinas into the Mid Atlantic, as colder temperatures aloft move into the region. Depending on the extent of heating and moistening in the wake of early convection, redevelopment of organized convection will be possible during the afternoon and early evening, potentially accompanied by a threat for locally damaging wind, isolated hail, and possibly a tornado. ...Eastern parts of the Ohio Valley into WV/PA/western NY... Guidance varies regarding the extent of moistening and destabilization from eastern OH into PA and western NY on Wednesday afternoon, though organized storm development could occur as the primary midlevel cyclone and attendant cold temperatures aloft overspread the region. If deeper and more robust updrafts can be sustained, then a few organized cells or line segments will be possible, accompanied by some severe threat. Higher probabilities may eventually be needed, if confidence increases in sufficient diurnal moistening/destabilization across the region. ..Dean.. 03/03/2025 Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1133 AM CST Mon Mar 03 2025 Valid 041200Z - 051200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR PARTS OF SOUTHEAST OK...NORTHEAST TX...SOUTHERN AR...CENTRAL/NORTHERN LA...CENTRAL/SOUTHERN MS...SOUTHWEST AL...AND THE WESTERN FL PANHANDLE... ...SUMMARY... Severe thunderstorms with a threat of tornadoes, damaging winds, and isolated hail are possible on Tuesday from eastern portions of the southern Plains into the lower Mississippi Valley and Southeast. A couple strong tornadoes will be possible. ...Synopsis... A strong and deep mid/upper-level shortwave trough and embedded midlevel cyclone will move eastward from the central/southern Great Plains into the Mississippi Valley on Tuesday. A deepening surface cyclone is forecast to move eastward across KS through the day, and then northeastward across parts of MO/IL Tuesday night. Relatively modest low-level moisture (with dewpoints in the 40s/low 50s F) will stream northward within the warm sector of this cyclone into parts of the Midwest, with richer moisture (60s F dewpoints) remaining confined to parts of the lower Mississippi Valley and Southeast. ...ArkLaTex region into the Lower Mississippi Valley and Southeast... Organized convection will likely be ongoing at the start of the forecast period Tuesday morning across parts of eastern OK/TX and perhaps southeast KS. The extent to which the morning convection will become surface-based remains somewhat uncertain, but very strong low-level and deep-layer shear and sufficient instability will support a conditional risk of all severe hazards with the early-day storms as they approach the ArkLaTex region. A strongly sheared QLCS is expected to approach the lower Mississippi Valley region by early afternoon. The magnitude of the severe threat with this QLCS, as well as the potential for preceding supercells, will be determined by the extent to which low-level moistening can keep pace with the primary convective line. Very strong flow in the lowest 3 km and 0-1 km SRH increasing above 400 m2/s2 will support a threat of potentially widespread damaging winds and line-embedded tornadoes wherever the organized QLCS can remain near-surface-based. The potential for longer-lived supercells is more uncertain, but cannot be ruled out immediately ahead of the QLCS, and also where large-scale ascent is somewhat weaker in closer proximity to the Gulf Coast. Any persistent discrete or embedded supercells could pose a threat of a strong tornado within the very strongly sheared environment. The northern/eastern extent of organized severe potential into Tuesday night will be constrained by increasingly prohibitive low-level stability. However, given the strength of the flow fields, any organized convection that persists into late Tuesday and early Wednesday could pose some risk of damaging wind, with some tornado threat potentially persisting in closer proximity to the Gulf Coast. ...Parts of eastern Kansas into Missouri... A few strong elevated storms could persist into Tuesday morning across parts of eastern KS into MO, potentially posing some threat of hail and locally gusty winds. The extent of diurnal heating in the wake of morning convection remains uncertain, but some surface-based destabilization will be possible during the afternoon as the midlevel cyclone and attendant cold temperatures aloft move over the region. If sufficient heating/destabilization can occur, then robust storm development will be possible in the vicinity of the eastward-moving cyclone, posing a risk of isolated hail, strong gusts, and possibly a tornado. ..Dean.. 03/03/2025 Read more

A couple strong tornadoes will be possible. ...Synopsis... A strong and deep mid/upper-level shortwave trough and embedded midlevel cyclone will move eastward from the central/southern Great Plains into the Mississippi Valley on Tuesday. A deepening surface cyclone is forecast to move eastward across KS through the day, and then northeastward across parts of MO/IL Tuesday night. Relatively modest low-level moisture (with dewpoints in the 40s/low 50s F) will stream northward within the warm sector of this cyclone into parts of the Midwest, with richer moisture (60s F dewpoints) remaining confined to parts of the lower Mississippi Valley and Southeast. ...ArkLaTex region into the Lower Mississippi Valley and Southeast... Organized convection will likely be ongoing at the start of the forecast period Tuesday morning across parts of eastern OK/TX and perhaps southeast KS. The extent to which the morning convection will become surface-based remains somewhat uncertain, but very strong low-level and deep-layer shear and sufficient instability will support a conditional risk of all severe hazards with the early-day storms as they approach the ArkLaTex region. A strongly sheared QLCS is expected to approach the lower Mississippi Valley region by early afternoon. The magnitude of the severe threat with this QLCS, as well as the potential for preceding supercells, will be determined by the extent to which low-level moistening can keep pace with the primary convective line. Very strong flow in the lowest 3 km and 0-1 km SRH increasing above 400 m2/s2 will support a threat of potentially widespread damaging winds and line-embedded tornadoes wherever the organized QLCS can remain near-surface-based. The potential for longer-lived supercells is more uncertain, but cannot be ruled out immediately ahead of the QLCS, and also where large-scale ascent is somewhat weaker in closer proximity to the Gulf Coast. Any persistent discrete or embedded supercells could pose a threat of a strong tornado within the very strongly sheared environment. The northern/eastern extent of organized severe potential into Tuesday night will be constrained by increasingly prohibitive low-level stability. However, given the strength of the flow fields, any organized convection that persists into late Tuesday and early Wednesday could pose some risk of damaging wind, with some tornado threat potentially persisting in closer proximity to the Gulf Coast. ...Parts of eastern Kansas into Missouri... A few strong elevated storms could persist into Tuesday morning across parts of eastern KS into MO, potentially posing some threat of hail and locally gusty winds. The extent of diurnal heating in the wake of morning convection remains uncertain, but some surface-based destabilization will be possible during the afternoon as the midlevel cyclone and attendant cold temperatures aloft move over the region. If sufficient heating/destabilization can occur, then robust storm development will be possible in the vicinity of the eastward-moving cyclone, posing a risk of isolated hail, strong gusts, and possibly a tornado. ..Dean.. 03/03/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1044 AM CST Mon Mar 03 2025 Valid 031700Z - 041200Z ...EXTREMELY CRITICAL FIRE WEATHER AREA FOR MUCH OF EASTERN NEW MEXICO AND SOUTHWEST TEXAS... ...CRITICAL FIRE WEATHER AREA FOR MUCH OF THE SOUTHERN HIGH PLAINS... ...17z Update... Widespread critical to extremely critical fire-weather conditions are likely across much of the southern High Plains today. Morning observations show clearing skies and poor overnight humidity recoveries across much of eastern NM and southwest TX. Mid-level flow will dramatically increase late this morning through the afternoon as the upper trough and an 80-100 kt mid-level jet moves overhead. The increase in momentum aloft, in combination with the rapidly deepening lee low over eastern CO should allow for surface wind gusts of 45-60 mph over much of the southern High Plains. With afternoon RH minimums of 5-7%, widespread extremely critical conditions are likely within dry fuels. See the prior outlook for more information. The main changes implemented were to trim areas that received enough wetting rainfall to temper concerns somewhat across parts of western OK and the eastern TX Panhandle. The extremely critical was also expanded into western portions of the TX Panhandle where confidence has increased in strong wind gusts and very low RH supporting extreme fire behavior. ..Lyons.. 03/03/2025 .PREV DISCUSSION... /ISSUED 0132 AM CST Mon Mar 03 2025/ ...Synopsis... A pronounced mid-level trough will traverse the southern Rockies, encouraging rapid intensification of a surface low over the central High Plains. During the afternoon, a dryline will advance eastward across the southern High Plains, with very strong winds and low RH overspreading dry fuels in the post-dryline environment, supporting dangerous, rapid wildfire-spread potential. Surface west-southwesterly winds will exceed 20 mph and coincide with 15-20 percent RH on a widespread basis across much of the southern High Plains, with Elevated and Critical highlights maintained. There is persistence among the consensus in model guidance in showing 30-40 mph sustained west-southwesterly surface winds amid 5-10 percent RH across portions of eastern New Mexico and Far West Texas. Given near critically dry fuels, the aforementioned meteorological conditions may support extreme wildfire behavior/spread, warranting the continuance of Extremely Critical highlights. ...Please see www.spc.noaa.gov/fire for graphic product...
