Severe Storms

SPC 0600Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1252 AM CDT Tue Sep 09 2025 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered showers and thunderstorms are possible over parts of the Northwest, northern Rockies with more isolated storms over the High Plains Wednesday. A stronger storm or two is possible, but severe potential is overall low. ...High Plains... East of a deepening upper low and 40-50 kt mid-level jet over the Great Basin and Northwest, shortwave ridging will persist across the Rockies and adjacent High Plains. A broad lee trough is expected to sharpen through the afternoon as weak ascent from the upper trough and mid-level jet glance the western edge of the upper ridge. The strongest ascent will be focused north and west over MT where a weak surface cyclone is expected to form by Wednesday afternoon. This will help draw richer low-level moisture westward later in the afternoon/evening. The late arrival of the more robust moisture suggests buoyancy will be limited, while capping remains stout over the northern and central High Plains. Still, robust heating and sufficient low-level moistening will allow for isolated high-based thunderstorms along the length of the surface trough across eastern MT/WY and western SD. A stray gust or two is possible, but limited buoyancy and forcing suggest the severe risk is low. Farther south, a weak secondary low is expected to form over the Raton Mesa. Enhanced easterly low-level upslope flow could support isolated storms late afternoon or into early evening. However, weak subsidence and warm mid-level temperatures beneath the upper ridge suggest remnant capping is likely to remain in place, limiting storm coverage/intensity. While moderate buoyancy is expected (1500-2500 J/kg) and an isolated stronger gust is possible, overall severe potential appears rather limited. ...Northwest and northern Rockies... Beneath the upper low, broad ascent and the southerly mid-level jet will overspread modest low-level moisture ahead of a weak cold front over the Intermountain West. Filtered daytime heating between remnant cloud cover will aide in scattered storm development across the higher terrain from eastern WA/OR into northern ID and western MT Wednesday afternoon. The increase in southerly flow aloft will elongate mid and upper-level hodographs to some degree, with 20-30 kt of bulk shear expected. This could support a few stronger storms, especially over portions of central ID and into western MT where ascent will be maximized. Given the steep low and mid-level lapse rates, a few strong gusts are possible. However, the threat for more organized/persistent severe storms appears limited by weaker buoyancy (MLCAPE ~500 J/kg) and moisture. ..Lyons.. 09/09/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1254 AM CDT Tue Sep 09 2025 Valid 091200Z - 101200Z ...Synopsis... An upper-level trough will continue to make slow eastward progress today. Stronger mid-level winds will push into the southern and eastern Great Basin. Farther north and west, lift from the upper low will promote widely scattered to scattered showers and thunderstorms in parts of the Northwest and northern Rockies. ...Northwest/northern Rockies... Thunderstorms are possible periodically in the Northwest. Portions of the Columbia Basin may see storms both in the morning and overnight tonight. Most areas have had recent precipitation and fuels indices have been trending toward lower fire weather concerns. However, there are pockets of remaining dry fuels in the Columbia Basin where there will be some concern for lightning ignitions. ...Southern/eastern Great Basin... With the stronger mid-level winds overspreading the region, 15-20 mph winds (locally up to 25 mph) can be expected in southern/eastern Nevada into western Utah. RH could locally dip as low as 10-15%, but 15-20% will be more common.

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1224 AM CDT Tue Sep 09 2025 Valid 091200Z - 101200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE CENTRAL AND SOUTHERN HIGH PLAINS... ...SUMMARY... Isolated severe storms are possible over the central and southern High Plains late this afternoon and evening. ...Central/Southern High Plains... Upper ridge, currently located over the Rockies, will gradually shift into the High Plains during the latter half of the period. This flow regime will encourage lee troughing across the central/southern High Plains, and a nocturnal LLJ is also expected across the TX Panhandle into western KS. In the absence of meaningful short waves, strong boundary-layer heating will prove instrumental in convective development as weak height rises are noted across the Plains. Latest model guidance suggests convective temperatures will be breached between 21-23z as surface readings climb through the upper 80s to near 90F from west TX into eastern CO. While thunderstorms may be delayed over the plains until late afternoon, scattered convection should readily develop over the higher terrain by mid afternoon. Some of this activity will spread toward lower elevations where favorable low-level convergence is expected to aid at least a few strong-severe thunderstorms. While deep-layer shear is not forecast to be particularly strong, adequate flow is expected to support some organization. Even so, storm coverage should remain isolated and a MRGL Risk will be maintained, primarily due to storm coverage and negligible large-scale support. Large hail is the primary concern with this activity. ..Darrow/Wendt.. 09/09/2025 Read more

WW 608 SEVERE TSTM KS OK TX 082150Z - 090500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 608 NWS Storm Prediction Center Norman OK 450 PM CDT Mon Sep 8 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southwest and South-Central Kansas Northwestern Oklahoma Northeast Texas Panhandle * Effective this Monday afternoon from 450 PM until Midnight CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...A moderately unstable and strongly sheared environment exists from the northeast TX Panhandle into southwest/south-central KS. Thunderstorm development is underway within this airmass, and the development of a few supercell appears likely. Large to isolated very large hail is the primary severe hazard, with a few strong downdrafts possible as well. Given the supercell storm mode and presence of surface boundaries, a brief tornado cannot be ruled out. The severe thunderstorm watch area is approximately along and 75 statute miles east and west of a line from 35 miles west northwest of Medicine Lodge KS to 30 miles east southeast of Borger TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 28025. ...Mosier Read more

MD 2051 CONCERNING SEVERE THUNDERSTORM WATCH 608... FOR FAR SOUTHWEST KANSAS INTO THE NORTHERN TEXAS PANHANDLE
Mesoscale Discussion 2051 NWS Storm Prediction Center Norman OK 0731 PM CDT Mon Sep 08 2025 Areas affected...far southwest Kansas into the northern Texas Panhandle Concerning...Severe Thunderstorm Watch 608... Valid 090031Z - 090330Z The severe weather threat for Severe Thunderstorm Watch 608 continues. SUMMARY...Scattered storms producing damaging hail may persist for several more hours from far northwest Oklahoma into the Texas Panhandle. DISCUSSION...Severe storms producing hail, some with a history of sizes > 2-3", continue to affect a small portion of southwest KS, northwest OK, and the northeast TX Panhandle this evening. Isolated activity also extends into north-central OK, though these storms are weaker and will be mitigated by increasing CIN and cooler upstream surface temperatures. The more robust storms, situated on the warm side of the KS outflow boundary and extending southwestward near the surface thermal ridge, are expected to have greater longevity as capping will be slower to increase there. A modest low-level jet up to 40 kt will also help to maintain boundary layer mixing/warmth, further supporting a narrow corridor of persistent threat well into the evening and west of the larger CIN. ..Jewell.. 09/09/2025 ...Please see www.spc.noaa.gov for graphic product...
