Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1250 AM CDT Sun May 25 2025 Valid 251200Z - 261200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE SOUTHERN PLAINS... ...SUMMARY... Severe storms, including the risk for very large hail, severe winds, and a few tornadoes, are expected across portions of the southern Plains. A risk of severe also extends across the Mid-South into northern Alabama. ...Southern Plains to northern Alabama... Subtle but potentially significant short-wave trough is expected to eject across northern Mexico into the southern High Plains later today. This feature will lift northeast ahead of the more significant trough that will advance into the southern Rockies by the end of the period. Confluent flow across the northern Plains favors dominant surface high building south in the lee of the Rockies. Leading edge of this air mass should spread south across eastern CO/western KS early in the period and a cold front should extend across the central TX Panhandle-northwestern OK by 18z. There may be a propensity for this boundary to settle a bit farther south than the models suggest, especially if significant precipitation develops pre-dawn across the central Plains. Early this morning, isolated thunderstorms were gradually increasing in areal coverage across northern OK into southern KS. This activity is evolving within a warm advection zone that appears favorable for upscale growth into the early parts of the period. If an MCS matures over eastern KS/MO it would likely turn and propagate southeast into western portions of the TN Valley/Mid-South later this afternoon. Damaging winds would be the primary severe threat, though some hail could be noted. Of more concern will be the potential for organized convection across the southern High Plains later this afternoon. Synoptic front should prove instrumental in robust thunderstorm development. Latest model guidance suggests the strongest boundary-layer heating will occur across far West TX/southeast NM into the TX South Plains. Forecast soundings suggest convective temperatures will easily be breached just ahead of the cold front and thunderstorms should readily develop along this wind shift, as weak large-scale ascent is expected ahead of the approaching short wave. Additionally, 700mb temperatures are forecast to cool a few degrees and CINH should be weaker. Steep lapse rates and seasonally high buoyancy favor strong updrafts within a modestly sheared environment. Supercells are expected to initiate across eastern NM/southern TX Panhandle into southwestern OK by 21z, then grow upscale into the evening as LLJ strengthens into this region of the southern Plains. Very large hail is possible with supercells, but a larger complex of storms may ultimately evolve. If an MCS matures, as expected, then severe winds may become more common downstream. Some tornado risk will also be noted with supercells. ..Darrow/Thornton.. 05/25/2025 Read more

MD 0963 CONCERNING SEVERE THUNDERSTORM WATCH 320... FOR EAST-CENTRAL CO INTO WESTERN KS
Mesoscale Discussion 0963 NWS Storm Prediction Center Norman OK 1134 PM CDT Sat May 24 2025 Areas affected...East-central CO into western KS Concerning...Severe Thunderstorm Watch 320... Valid 250434Z - 250600Z The severe weather threat for Severe Thunderstorm Watch 320 continues. SUMMARY...Strong to isolated severe storms will remain possible overnight. DISCUSSION...An earlier cluster of storms over east-central CO has weakened somewhat over the last hour, though persistent redevelopment is occurring along its southwest flank, and there is some indication that a weak MCV has formed in association with this convection. Convection will tend to remain elevated overnight as it spreads east-southeastward, but MUCAPE ranging from 500-1500 J/kg and sufficient deep-layer shear will continue to support occasionally organized storms and perhaps an elevated bowing cluster overnight, with a threat of at least isolated hail and strong/severe gusts. Additional elevated storms may eventually develop downstream of the ongoing cluster, within a low-level warm advection regime. These storms could also pose an isolated hail threat. With some severe potential expected to continue overnight, downstream watch issuance is possible. ..Dean/Mosier.. 05/25/2025 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 0962 NWS Storm Prediction Center Norman OK 1112 PM CDT Sat May 24 2025 Areas affected...Parts of western/central OK Concerning...Tornado Watch 319... Valid 250412Z - 250545Z The severe weather threat for Tornado Watch 319 continues. SUMMARY...Some supercell threat may persist past Midnight CDT. DISCUSSION...Two small supercells developed this evening across northwest OK. However, despite the presence of strong to extreme instability, these cells have struggled to grow and maintain severe intensity, likely due to lingering warm temperatures aloft and a lack of stronger large-scale ascent. A strengthening low-level jet is noted on recent VWPs from KOUN and KFDR, and this may yet allow for some intensification of the remaining supercell, and/or development of new storms near/north of the quasi-stationary front. In the short term, some threat for all severe hazards cannot be ruled out with the ongoing supercell through and past Midnight CDT, though increasing MLCINH may limit its longevity. Any new development may tend to be slightly elevated, but could still pose a severe threat given the favorable instability and shear across the region. ..Dean.. 05/25/2025 ...Please see www.spc.noaa.gov for graphic product...
