Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0358 AM CST Sun Nov 23 2025 Valid 261200Z - 011200Z ...DISCUSSION... The warm sector will be onshore at the beginning of the period D4/Wed from the Southeast coast to the Carolinas. This may permit a few thunderstorms along the cold front early Wednesday before the front moves into the Atlantic. In the wake of this front, cool, dry air and high pressure will build across much of the central and eastern CONUS. This will result in minimal thunderstorm activity/severe weather potential Thursday and Friday. By next weekend, return flow will resume across the southern Plains and thunderstorm chances will increase. Most guidance shows a large trough across the western CONUS by the end of the weekend and into early next week, but the orientation, size, and timing of this trough remains uncertain. Severe weather potential will likely return at some point given the approaching trough and inland moisture intrusion, but uncertainties are too high for severe weather probabilities at this time.Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0227 AM CST Sun Nov 23 2025 Valid 251200Z - 261200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE SOUTHEAST... ...SUMMARY... A few strong to isolated severe storms are possible across portions of the Southeast on Tuesday. ...Synopsis... A mid-level trough will amplify across the eastern CONUS on Tuesday with ridging across the West. A cold front will sharpen near the Mississippi River and cross the Appalachians by the end of the period. ...Southeast... Mid 60s dewpoints will stream northward ahead of a cold front across the Southeast on Tuesday. This will result in moderate destabilization within a zone of moderate to strong deep-layer shear. Minimal inhibition is expected along the front by mid-afternoon which should support isolated to scattered storm development. A strong low-level jet, initially across MS/TN/AL during the morning, will move quickly east and is forecast over the Mid-Atlantic by 00Z. If this occurs, low-level shear will not be that strong along the frontal zone Tuesday afternoon/evening. Therefore, isolated large hail will likely be the primary severe weather threat. Storm intensity is expected to lessen by late evening due to the cooling boundary layer ahead of the cold front. ...South Texas... The southwestern edge of the surface cold front will stall across South Texas Tuesday afternoon/evening. The environment south of this front will feature moderate instability and shear. Upper forcing may be somewhat nebulous, but convergence along the front may be sufficient for isolated to widely scattered storms late Tuesday afternoon into the evening. If storms develop, large hail will likely be the primary threat. ..Bentley.. 11/23/2025Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1252 AM CST Sun Nov 23 2025 Valid 241200Z - 251200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN EAST TEXAS TO FAR SOUTHERN ARKANSAS... ...SUMMARY... Scattered severe thunderstorms are possible from later Monday afternoon into Monday night across east Texas towards the Ark-La-Miss. A few tornadoes along with large hail and damaging winds are anticipated. ...Synopsis... A mid-level shortwave trough will traverse the central/southern states on Monday with a second mid-level trough advancing from the Northwest to the northern Plains. At the surface, high pressure will dominate much of the eastern CONUS with broad low pressure across the Plains and Upper Midwest. A warm front near the Gulf Coast Monday morning will lift north through the day. ...East Texas to southern Arkansas... Elevated thunderstorms will be ongoing at the beginning of the period from north-central Texas to southern Arkansas to the north of a warm front. Isolated large hail is possible with these storms, but a more widespread threat is not expected during the morning. The warm front will advect northward quickly through the day and lead to moderate destabilization across the warm sector. A messy storm mode is expected along the warm front for much of the day with some marginal severe threat. The greatest severe weather threat should begin by mid-afternoon as height falls overspread the warm sector and slight mid-level cooling results in an uncapped warm sector. This should result in scattered supercell development within the open warm-sector by late afternoon. A strengthening low-level jet (40-45 knots) is expected to overspread the warm sector during this same timeframe. This may result in a brief window during the late afternoon to early evening where a few tornadoes (perhaps strong) could occur. A nocturnal wind/tornado threat may persist into the late evening/overnight period as rich low-level moisture will help to maintain an unstable boundary layer into the overnight period where cyclonically curved low-level hodographs will persist. ..Bentley.. 11/23/2025Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1246 AM CST Sun Nov 23 2025 Valid 241200Z - 251200Z ...NO CRITICAL AREAS... ...Synopsis... No fire-weather concerns are anticipated on Monday due to an overall lack of overlap of dry/windy conditions with receptive fuels. Cooler temperatures, weaker surface winds, and recent wetting rainfall will all serve to reduce the threat for wildfire ignition and spread. ..Halbert.. 11/23/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1246 AM CST Sun Nov 23 2025 Valid 231200Z - 241200Z ...NO CRITICAL AREAS... ...Synopsis... There are no fire-weather concerns forecast for Sunday. A lack of dry and windy conditions coupled with cooler temperatures and recent wetting rainfall will mitigate any threat for wildfire ignition and spread. ..Halbert.. 11/23/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1134 PM CST Sat Nov 22 2025 Valid 231200Z - 241200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS MUCH OF WESTERN INTO NORTHWEST TEXAS... ...SUMMARY... Isolated hail is possible beginning this afternoon across parts of west to north-central Texas. ...Synopsis and Discussion... An upper low will pivot from AZ into CO today, with a midlevel speed max moving into the southern High Plains. Cooling aloft will persist across the region throughout the period, leading to steepening lapse rates aloft. At the surface, high pressure will maintain relatively cool surface temperatures over the Plains and MS Valley, though 50s F dewpoints will develop northward into western TX, and near 60 F dewpoints into central TX by 12Z Monday. As the upper trough emerges into the plains, large-scale ascent will move out of NM and into TX and western OK. While the surface air mass will be cool most areas, elevated instability should be substantial due to a southerly low-level jet with strong theta-e advection. Forecast soundings suggest perhaps 1000 J/kg MUCAPE will be possible, along with favorable effective shear over 40 kt. As such, elevated convection should strengthen from eastern NM into western TX, with the greatest severe hail potential over TX where instability will be strongest. Isolated large hail seems likely after about 18Z. Otherwise, there is a conditional threat of an isolated, surface-based supercell over far western TX in the Pecos/Fort Stockton area, where a narrow zone of SBCAPE may develop due to stronger heating. However, it is uncertain if any storms will form along the weak boundary. ..Jewell/Halbert.. 11/23/2025Read more
