SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1225 PM CDT Sun Sep 14 2025 Valid 151200Z - 161200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorm potential appears generally low on Monday. ...Synopsis... An upper-level trough will pivot northeastward through Minnesota early in the period. To the West, another shortwave trough will move into the Northern Rockies. A weak surface trough will exist in the central/northern Plains. ...Upper Mississippi Valley southward into the Ozarks... Current guidance continues to suggest that the shortwave trough moving northeastward through Minnesota will not be well phased with the greatest surface heating. However, the ECMWF remains slower than other guidance in this regard. Greater buoyancy will more likely develop from central Minnesota/western Wisconsin southward into the Ozarks. However, these areas will be increasingly removed from the departing mid-level ascent and stronger wind shear. Occasionally strong storms are possible during the afternoon within the pockets of greater buoyancy, but the a large scale pattern suggests these storms will be quite isolated and brief. ...Central into Northern High Plains... Widely scattered to scattered convection is possible from central Wyoming into portion of the High Plains to the east. Cloud cover associated with the upper trough to the west and limited low-level moisture will limit the intensity of this activity. Even so, steep mid-level lapse rates and pockets of steeper low-level lapse rates could support stronger wind gusts. ...North Carolina Tidewater... An offshore surface low will move inland late Monday into Tuesday morning. While low-level shear will be enhanced, precipitation/clouds trough the day/evening should keep buoyancy inland limited. Confidence in a low-end severe threat remains very low. ..Wendt.. 09/14/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1144 AM CDT Sun Sep 14 2025 Valid 141700Z - 151200Z ...NO CRITICAL AREAS... ...17z Update... Modestly dry/breezy conditions remain possible south of an upper trough advancing through the northern Great Basin this afternoon. However, poor overlap of the lower humidity and winds near 15 mph with receptive fuels should keep any concerns very localized. Elsewhere, higher humidity and recent precipitation should keep fire-weather concerns low. No changes were made to the prior outlook. ..Lyons.. 09/14/2025 .PREV DISCUSSION... /ISSUED 0147 AM CDT Sun Sep 14 2025/ ...Synopsis... A mid-level trough will traverse the Pacific Northwest and northern Rockies as another upper trough ejects into the Plains today. Modestly dry and breezy conditions will result across portions of the Great Basin. However, the marginally favorable low-level RH, and fuels that are poorly receptive to wildfire spread, suggest that the chances for significant wildfire ignition and growth are relatively low. The lifting of a buoyant airmass ahead of the western upper trough will support scattered thunderstorm development across portions of the Pacific Northwest into the northern Rockies. However, fuels do not appear dry enough for robust lightning ignitions to warrant any dry thunderstorm highlights. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
