SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 PM CDT Fri Nov 01 2024 Valid 031200Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL AND SOUTHERN PLAINS... ...SUMMARY... Scattered severe storms are possible, mainly during the late afternoon and evening on Sunday, across parts of the central and southern Great Plains. ...Synopsis... A deep/high-amplitude upper trough will continue advancing steadily eastward across the western U.S. Sunday, and will begin to emerge into the High Plains late. At the surface, an associated cold front will likewise advance eastward out of the Rockies, and should extend from the Upper Mississippi Valley vicinity south-southwestward to the southern Plains by Monday morning. ...Central and southern Plains... The potential for severe weather Sunday is difficult to delineate, given widespread/substantial prior -- and ongoing -- convection across the Oklahoma/northern Texas area. As such, areas of potentially greater destabilization remain uncertain. Despite this, an amply moist warm sector and favorably sheared environment will exist ahead of the advancing upper system, which should support severe storms locally. Therefore, maintenance of a large/rather broad risk area across portions of the central and southern Plains remains the most reasonable forecast. Where greater instability can evolve, potentially on western fringes of the outlook area from western Kansas south across the Texas Big Country, risk for large hail and a couple of tornadoes could evolve. Otherwise, locally damaging wind gusts would appear to be the most likely risk -- which may persist well into the overnight hours. ..Goss.. 11/01/2024 Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1227 PM CDT Fri Nov 01 2024 Valid 021200Z - 031200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE PERMIAN BASIN VICINITY EAST-NORTHEASTWARD INTO SOUTHWESTERN OKLAHOMA... ...SUMMARY... Isolated severe storms are expected Saturday and Saturday night across parts of the southern Great Plains. The most likely corridor for a couple tornadoes and large hail is across parts of the Permian Basin and South Plains of Texas during the late afternoon and early evening. ...Synopsis... Digging/intensification -- and gradual/steady progression -- of the western U.S. upper trough is expected Saturday. As this system shifts from the West Coast states across the Great Basin and into the Desert Southwest, substantial downstream mid-level height falls will occur across the central and southern Plains. At the surface, a remnant baroclinic zone -- extending from Texas eastward across the Southeast -- will mark the northern extent of the moist Gulf low-level airmass. This boundary -- in response to persistent southeasterly low-level flow -- should tend to retreat northwestward across Texas/Oklahoma, though likely to become impeded by convective outflow. The result will likely become a convectively reinforced boundary extending from the Permian Basin vicinity east-northeastward into Oklahoma, which will focus persistent, regenerative convection and some attendant severe risk through the period. ...Transpecos region and southeastern New Mexico northeastward into central and northern Oklahoma... Showers and thunderstorms are forecast to be ongoing at the start of the period from southeastern New Mexico northeastward into southern Kansas, with potentially some local/low-end severe risk on the southern fringe of this convection. South of the convection, some heating/destabilization is expected -- particularly across the Transpecos/Permian Basin region. Here, an afternoon increase in convection -- likely in the form of supercells -- is expected to occur. Here, large hail will be possible, along with potential for locally damaging winds, and a couple of tornadoes. Into the evening, convection should increase in coverage -- likely evolving into multiple linear bands, as a low-level jet increases. Though instability should remain lesser with northeastward extent into Oklahoma, owing to relatively weak lapse rates, multiple rounds of banded convection should be accompanied by risk for locally strong wind gusts, along with marginal hail and potentially a tornado or two. This potential should persist well into the overnight hours. ..Goss.. 11/01/2024 Read more

Isolated severe storms are expected Saturday and Saturday night across parts of the southern Great Plains. The most likely corridor for a couple tornadoes and large hail is across parts of the Permian Basin and South Plains of Texas during the late afternoon and early evening. ...Synopsis... Digging/intensification -- and gradual/steady progression -- of the western U.S. upper trough is expected Saturday. As this system shifts from the West Coast states across the Great Basin and into the Desert Southwest, substantial downstream mid-level height falls will occur across the central and southern Plains. At the surface, a remnant baroclinic zone -- extending from Texas eastward across the Southeast -- will mark the northern extent of the moist Gulf low-level airmass. This boundary -- in response to persistent southeasterly low-level flow -- should tend to retreat northwestward across Texas/Oklahoma, though likely to become impeded by convective outflow. The result will likely become a convectively reinforced boundary extending from the Permian Basin vicinity east-northeastward into Oklahoma, which will focus persistent, regenerative convection and some attendant severe risk through the period. ...Transpecos region and southeastern New Mexico northeastward into central and northern Oklahoma... Showers and thunderstorms are forecast to be ongoing at the start of the period from southeastern New Mexico northeastward into southern Kansas, with potentially some local/low-end severe risk on the southern fringe of this convection. South of the convection, some heating/destabilization is expected -- particularly across the Transpecos/Permian Basin region. Here, an afternoon increase in convection -- likely in the form of supercells -- is expected to occur. Here, large hail will be possible, along with potential for locally damaging winds, and a couple of tornadoes. Into the evening, convection should increase in coverage -- likely evolving into multiple linear bands, as a low-level jet increases. Though instability should remain lesser with northeastward extent into Oklahoma, owing to relatively weak lapse rates, multiple rounds of banded convection should be accompanied by risk for locally strong wind gusts, along with marginal hail and potentially a tornado or two. This potential should persist well into the overnight hours. ..Goss.. 11/01/2024 Read more
