SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0749 AM CDT Sun Aug 03 2025 Valid 031300Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL AND SOUTHERN HIGH PLAINS... ...SUMMARY... Large to very large hail and damaging winds will be possible this afternoon and evening over parts of the central/southern High Plains. Additional strong to severe storms are probable in the Northwest during the afternoon. ...Southern Plains... A decaying MCS is currently moving through the eastern TX Panhandle and western OK. Expectation is for this system to continue south-southeastward for the next several hours while gradually weakening. Cool outflow and cloud cover associated with this system will have an impact on the severe potential across the region today, leading to above-average uncertainty regarding the overall convective evolution. The overall environment from the TX Panhandle southward through the South Plains and eastward into western OK and northwest TX will be characterized by moderate northwesterly flow aloft, steep mid-level lapse rates, and afternoon surface dewpoints ranging from the upper 50s to upper 60s. These conditions will support moderate to strong buoyancy across much of the region, but areas under the influence of the MCS's outflow and/or cloud cover will likely remain capped due to limited/filtered diurnal heating. Current expectation is for the TX South Plains and Permian Basin to remain south of the outflow, allowing for strong heating and airmass destabilization. The outflow is expected to act as the primary impetus for convective initiation across the region this afternoon. Additional areas of low-level convergence near a weak surface low over southeast NM and the weak lee troughing extending from southeast CO across eastern NM could result in a few storms as well. Low-level easterly/southeasterly flow veering to northwesterly in the mid levels will result in moderate vertical shear, with the overall wind profile quite supportive for large hail. As such, there is a conditional risk for supercells capable of large to very large hail. With time, some upscale growth into one or more linear clusters with an increased risk for damaging gusts is possible. ...Central High Plains... Early morning surface analysis placed a broad area of low pressure from northeast CO into southwest SD. A low is expected develop within this region by the early afternoon, and low-level convergence in the vicinity of this low will likely result in thunderstorm initiation. Late afternoon initiation is possible along the weak lee trough across eastern WY as well. Moderate buoyancy will support strong updrafts, but vertical shear is forecast to be weak, limiting storm organization and longevity. Isolated hail and damaging gusts are possible, particularly with any forward-propagating clusters that can develop. ...Northwest... Shortwave trough currently off the northern CA coast is forecast to continue northeastward today, with lift associated with this system impinging on the region by the early afternoon. Increasing mid-level moisture (already apparent on the 12Z BOI sounding) will help support moderate buoyancy and the development of scattered to numerous thunderstorm this afternoon and evening. A belt of stronger mid-level flow ahead of the shortwave will increase deep-layer shear to 30-40 kt, supporting some storm organization. Steep lapse rates with inverted-v thermodynamic profiles and the potential for high-based semi-organized clusters will favor strong downdrafts capable of occasional severe gusts with the stronger storms. Small hail will also be possible with any more persistent clusters or weak supercell structures despite the limited buoyancy. ..Mosier/Bentley.. 08/03/2025 Read more

Valid 030738Z - 030915Z The severe weather threat for Severe Thunderstorm Watch 568 continues. SUMMARY...A few severe storms are likely to persist through the early morning. DISCUSSION...A cluster of storms continues southeastward this morning across the Texas Panhandle. The western storm has recently strengthened with a tightening reflectivity gradient on the leading edge of the supercell. This storm will likely have the greatest severe weather threat as it continues southeast over the next 1 to 2 hours. An additional stronger storm across Lipscomb county will move southeast into far western Oklahoma. However, it will also move into progressively less unstable air as it move east and therefore, its severe potential is not expected to persist as long as the western storm. Severe wind gusts will be the primary threat from both storms. ..Bentley/Mosier.. 08/03/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OUN...AMA...

SPC Aug 3, 2025 Day 4-8 Severe Weather Outlook

2 weeks 5 days ago
Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0358 AM CDT Sun Aug 03 2025 Valid 061200Z - 111200Z ...DISCUSSION... ...Wednesday/Day 4 to Friday/Day 6... A large-scale mid-level anticyclonic flow pattern will be in place over much of the central and western U.S during the mid week. At the surface, a moist and unstable airmass is forecast over the central and northern Plains. Within the broader scale flow, a shortwave ridge is forecast to move across the northern Plains from Wednesday into Thursday. In spite of relatively weak large-scale ascent, isolated thunderstorm development will be possible on Wednesday and Thursday as instability becomes maximized in the late afternoon and early evening. Moderate deep-layer shear should support a potential for isolated severe gust and hail. As the mid-level ridge moves eastward during the day on Thursday, flow is forecast to become southwesterly across the northern High Plains. Thunderstorms that develop in eastern Montana and western North Dakota Thursday evening could be associated with a severe threat. Isolated large hail and severe gusts will be possible. Model forecasts suggest an isolated severe threat will again be possible in the northern Plains on Friday, in the wake of the exiting ridge. ...Saturday/Day 7 and Sunday/Day 8... On Saturday, a mid-level trough is forecast to move into the northern High Plains, as flow remains southwesterly from the Dakotas into the upper Mississippi Valley. Model forecasts develop a relatively large cluster of thunderstorms Saturday evening ahead of the trough from northwestern Minnesota into eastern South Dakota. The models also have strong instability and moderate deep-layer shear in place ahead of the trough within the favored convective zone. This could support a potential for supercells with large hail and severe wind gusts. However, the steeper lapse rates are forecast to remain further south across the mid Missouri Valley, suggesting there is still some uncertainty concerning the magnitude of the severe threat. On Sunday, the severe threat is forecast to shift southeastward as a front moves across the region. The favored corridor would be along an axis of moderate instability from northeast Nebraska to northwestern Wisconsin. This position of the front and instability axis should be determined by the timing of the mid-level system, which is still considerably uncertain. Read more

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0358 AM CDT Sun Aug 03 2025 Valid 061200Z - 111200Z ...DISCUSSION... ...Wednesday/Day 4 to Friday/Day 6... A large-scale mid-level anticyclonic flow pattern will be in place over much of the central and western U.S during the mid week. At the surface, a moist and unstable airmass is forecast over the central and northern Plains. Within the broader scale flow, a shortwave ridge is forecast to move across the northern Plains from Wednesday into Thursday. In spite of relatively weak large-scale ascent, isolated thunderstorm development will be possible on Wednesday and Thursday as instability becomes maximized in the late afternoon and early evening. Moderate deep-layer shear should support a potential for isolated severe gust and hail. As the mid-level ridge moves eastward during the day on Thursday, flow is forecast to become southwesterly across the northern High Plains. Thunderstorms that develop in eastern Montana and western North Dakota Thursday evening could be associated with a severe threat. Isolated large hail and severe gusts will be possible. Model forecasts suggest an isolated severe threat will again be possible in the northern Plains on Friday, in the wake of the exiting ridge. ...Saturday/Day 7 and Sunday/Day 8... On Saturday, a mid-level trough is forecast to move into the northern High Plains, as flow remains southwesterly from the Dakotas into the upper Mississippi Valley. Model forecasts develop a relatively large cluster of thunderstorms Saturday evening ahead of the trough from northwestern Minnesota into eastern South Dakota. The models also have strong instability and moderate deep-layer shear in place ahead of the trough within the favored convective zone. This could support a potential for supercells with large hail and severe wind gusts. However, the steeper lapse rates are forecast to remain further south across the mid Missouri Valley, suggesting there is still some uncertainty concerning the magnitude of the severe threat.
