Severe Storms

SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0224 AM CST Sun Mar 02 2025 Valid 041200Z - 051200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS TUESDAY AFTERNOON AND EVENING ACROSS SOUTHERN ARKANSAS....MUCH OF NORTHERN AND CENTRAL LOUISIANA AND CENTRAL/SOUTHERN MISSISSIPPI... ...SUMMARY... One or two organized lines or clusters of thunderstorm, and perhaps a few supercells, will pose a risk for damaging wind gusts, a few tornadoes and hail, primarily across parts of the lower Mississippi Valley into Southeast, Tuesday through Tuesday night. ...Discussion... Latest model output remains a bit varied concerning the evolution and motion of a significant mid/upper trough, which is generally forecast to be in the process of shifting across and east of the southern Rockies Monday night into early Tuesday. However, guidance indicates that it will remain progressive, and likely to overspread much of the Mississippi Valley by the end of the period. In lower-levels a broad deep cyclone is likely to continue to evolve, with the center forecast to track from Kansas into the Upper Midwest by 12Z Wednesday. In the wake of a recent intrusion of dry/potentially cool air, associated with surface ridging shifting east of the Atlantic Seaboard, models indicate that an influx of moisture off the western Gulf Basin will advect eastward ahead of the cold front trailing the cyclone. However, northeast of the southeastern Great Plains into lower Mississippi Valley, the moisture return may remain elevated above a residual cool/stable near surface layer. Still, large-scale forcing for ascent and destabilization will probably be sufficient to support extensive thunderstorm development across the interior U.S., and a fairly broad area with at least a conditional risk for severe storms, given the strength of flow/shear in the evolving warm sector. ...Lower Mississippi Valley into Southeast... An initially well-defined near-surface baroclinic zone may extend from the Arkansas/Oklahoma vicinity southeastward through the lower Mississippi Valley at the outset of the period. While it appears that this boundary may become more diffuse while shifting eastward during the day, it may still provide the primary focus for an organizing cluster and/or discrete supercell development, as forcing for ascent associated with a short wave perturbation within the larger-scale mid/upper troughing overspreads the region. Of concern, models indicate that this feature will be accompanied by an intense jet core, which may include south-southwesterly winds of 70-100 kt in the 850-500 mb layer overspreading portions of Louisiana and Mississippi. These speeds appear generally forecast within the inflow layer of potential storm development, with speeds tending to weaken to 40-50 kt as they veer to a more westerly component in the potential downdraft source region. So uncertainty exists concerning the magnitude of potential downward mixing of momentum in convective development. Even so, particularly along the remnant boundary, the environment probably will become conducive to potential for damaging wind gusts, a few tornadoes and some hail across southern Arkansas and northern/ central Louisiana into Mississippi. As this activity spreads eastward Tuesday night, the extent to which near-surface thermodynamic profiles support a risk for damaging surface gusts and tornadoes across Alabama into Georgia remains unclear, but it seems likely to diminish with eastward extent and time. ..Kerr.. 03/02/2025 Read more

The second and larger in a series of mid-level troughs will traverse the Southern Rockies tomorrow (Monday), encouraging rapid surface low development along the High Plains. Behind a trailing surface dryline, widespread dry and windy conditions will prevail for several hours Monday afternoon, promoting dangerous wildfire-spread potential. Widespread 20+ mph sustained west-southwesterly surface winds amid 10-15 percent RH will become common across much of New Mexico into southeastern Colorado and western Texas, necessitating the introduction of broad Elevated/Critical highlights. However, deterministic and ensemble guidance consensus (including high-resolution members) depict a belt of 30-40 mph sustained west-southwesterly surface winds coinciding with 5-10 percent RH for at least a few hours across portions of eastern New Mexico into Far West Texas. In this area, fuel receptiveness is approaching critical thresholds, and when considering the intense winds with very low RH, at least localized to potentially widespread extreme wildfire-spread behavior is possible, with Extremely Critical highlights introduced. Multiple rounds of thunderstorms are expected to develop across the southern Plains Sunday into Monday. The southwestern most extent of these storms may occur across portions of western Texas into Oklahoma, which may temper wildfire-spread concerns in the northeastern portions of the Elevated and Critical highlights. As such, these particular highlights may need considerable adjustments in later outlooks. ..Squitieri.. 03/02/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

In this area, fuel receptiveness is approaching critical thresholds, and when considering the intense winds with very low RH, at least localized to potentially widespread extreme wildfire-spread behavior is possible, with Extremely Critical highlights introduced. Multiple rounds of thunderstorms are expected to develop across the southern Plains Sunday into Monday. The southwestern most extent of these storms may occur across portions of western Texas into Oklahoma, which may temper wildfire-spread concerns in the northeastern portions of the Elevated and Critical highlights. As such, these particular highlights may need considerable adjustments in later outlooks. ..Squitieri.. 03/02/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0119 AM CST Sun Mar 02 2025 Valid 021200Z - 031200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHEAST NEW MEXICO INTO WESTERN TEXAS... ...Synopsis... A series of mid-level troughs will traverse the southwest quadrant of the CONUS today, with the lead impulse ejecting into the southern Plains this afternoon. A vertically stacked cyclone with a trailing dryline will progress across the southern High Plains, promoting dry and windy conditions behind the dryline that are capable of supporting rapid wildfire spread. As the dryline surges east across western Texas by afternoon peak heating, 25+ mph sustained westerly surface winds will coincide with 15 percent RH while overspreading dry fine fuels. Thunderstorms (some potentially severe) will initiate along the dryline across the northern Texas Panhandle into Oklahoma, potentially limiting the northeastern most extent of favorable wildfire-spread conditions. While dry thunderstorms are not expected to be the main fire-weather concern, the first few lightning strikes during storm initiation may support fire starts, potentially being further exacerbated by dry/windy conditions from the passing dryline. Please see the latest Day 1 Convective Outlook for more information on the severe thunderstorm threat over parts of the southern Plains. ..Squitieri.. 03/02/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
