MD 0914 CONCERNING SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY FOR WESTERN NEBRASKA INTO CENTRAL SOUTH DAKOTA
Mesoscale Discussion 0914 NWS Storm Prediction Center Norman OK 0253 PM CDT Thu May 23 2024 Areas affected...Western Nebraska into central South Dakota Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 231953Z - 232200Z Probability of Watch Issuance...80 percent SUMMARY...A severe thunderstorm watch is likely this afternoon for parts of western Nebraska into central South Dakota. Very-large hail will be possible with initial supercells before a transition to a more linear mode. Severe wind gusts will then become the dominant threat. DISCUSSION...Cumulus continue to increase along a surface trough/cold front in western Nebraska and south-central South Dakota. With the approach of the shortwave trough now in western/central Wyoming, these trends should continue. Moisture continues to increase ahead of the boundary, particularly into western Nebraska, where a corridor of upper 50s F dewpoints are noted farther southeast in surface observations. Objective mesoanalysis shows decreasing MLCIN. Initiation of storms seems probable in the next 1-3 hours. Storms will initially be supercells capable of very large hail. Upscale growth may occur relatively quickly given the linear forcing and larger T/Td spreads at the surface. Severe wind gusts will become increasing likely as this transition occurs. ..Wendt/Hart.. 05/23/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FSD...ABR...LBF...UNR...

Valid 231916Z - 232115Z The severe weather threat for Severe Thunderstorm Watch 293 continues. SUMMARY...Wind damage and isolated large hail remains possible this afternoon. Storm coverage should increase into more central/eastern Kentucky over the next few hours. DISCUSSION...Storms continue to develop ahead of a weak MCV in the Mid-South. Destabilization continues into eastern Kentucky where temperatures have risen to near 80 F. A cluster of storms west of Bowling Green will pose a more organized threat of wind damage, particularly as buoyancy increases ahead of this activity. Isolated large hail is possible in the most intense, discrete storms. ..Wendt.. 05/23/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MRX...JKL...LMK...OHX...PAH...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0346 PM CDT Thu May 23 2024 Valid 251200Z - 311200Z ...Southwest into southern High Plains - Day 3/Saturday... Within the base of an eastward-moving large-scale trough over the West, a strong (60-70 kt) west-southwesterly midlevel jet streak will overspread the Southwest and southern High Plains during peak heating. This will promote a deepening lee cyclone over the central High Plains, with a southward-extending dryline over the southern Plains. West of the dryline, a tightening pressure gradient, coupled with deep boundary-layer mixing into the strong flow aloft, will yield widespread 20-25+ mph sustained westerly surface winds across NM and west TX. The combination of these winds and single-digit /lower-teens RH will favor an expansive area of critical fire-weather conditions across the region on Day 3/Saturday, given increasingly dry/receptive fuels. Critical meteorological conditions are also expected well into southeast CO/southwest KS, though fuels do not appear as receptive here. Additionally, pockets of extremely critical meteorological conditions are possible (especially over portions of eastern NM), though these conditions appear too localized for such highlights -- especially given the current state of fuels. Elevated to locally critical conditions may redevelop across similar areas on Day 4/Sunday, aided by a trailing belt of moderate westerly flow aloft and a weak lee cyclone over the central/southern High Plains. However, most guidance indicates a modest surface pressure gradient owing to the weak lee cyclogenesis, limiting confidence in any more than locally critical conditions at this time. Thereafter, a large-scale ridge will build over the West, generally limiting fire-weather concerns for the remainder of the extended forecast period. ..Weinman.. 05/23/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
