MD 2166 CONCERNING TORNADO WATCH 694... FOR SOUTHERN KANSAS AND NORTHWEST/CENTRAL/NORTHERN OKLAHOMA.
Mesoscale Discussion 2166 NWS Storm Prediction Center Norman OK 0345 PM CDT Wed Oct 30 2024 Areas affected...southern Kansas and northwest/central/northern Oklahoma. Concerning...Tornado Watch 694... Valid 302045Z - 302215Z The severe weather threat for Tornado Watch 694 continues. SUMMARY...The large hail/severe wind threat is expected to continue through the afternoon as supercells move across northwest Oklahoma and into southern Kansas. The tornado threat is expected to increase this evening. DISCUSSION...Supercells have developed along the dryline in western Oklahoma. Thus far, one measured wind gust of 70 mph has been observed with MRMS MESH suggesting around 1 to 1.25 inch hail. As these supercells mature, expect the threat for large hail and severe wind gusts to continue. Low-level shear is quite weak this afternoon (60-70 m2/s2 0-500 SRH per VNX VWP), but is forecast to increase substantially after 22-23Z as the low-level jet strengthens. During this time is when the greatest tornado threat is anticipated. Eventually, expect storms to congeal into a squall line with severe wind and a few embedded QLCS tornadoes as the primary threat. ..Bentley/Gleason.. 10/30/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2164 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR NORTHEAST KANSAS INTO SOUTHEAST NEBRASKA AND FAR NORTHWEST MISSOURI
Mesoscale Discussion 2164 NWS Storm Prediction Center Norman OK 0303 PM CDT Wed Oct 30 2024 Areas affected...northeast Kansas into southeast Nebraska and far northwest Missouri Concerning...Severe potential...Watch likely Valid 302003Z - 302200Z Probability of Watch Issuance...80 percent SUMMARY...Airmass recovery should result in some severe storms this afternoon and evening. DISCUSSION...Widespread showers and thunderstorms across northeast Kansas has stunted destabilization thus far. However, some clearing and low-level moisture advection in the wake of the morning activity has started to destabilize parts of northeast Kansas. A line of storms is starting to organize across central Kansas which is expected to continue to grow upscale as it moves northeast. Expect sufficient destabilization ahead of this line of storms for some threat for severe wind gusts, large hail, and potentially a few tornadoes (along and south of the front). A tornado watch will likely need to be issued within the next hour or two across northeast Kansas, to fill the gap between watch 693 and 694. ..Bentley/Gleason.. 10/30/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2165 CONCERNING SEVERE THUNDERSTORM WATCH 693... FOR SOUTHERN IOWA AND FAR NORTHERN MISSOURI
Mesoscale Discussion 2165 NWS Storm Prediction Center Norman OK 0305 PM CDT Wed Oct 30 2024 Areas affected...Southern Iowa and far northern Missouri Concerning...Severe Thunderstorm Watch 693... Valid 302005Z - 302200Z The severe weather threat for Severe Thunderstorm Watch 693 continues. SUMMARY...A line of storms will continue to pose a risk of damaging winds across southern Iowa and far northern Missouri over the next few hours. However, downstream watch issuance is not currently anticipated given recent convective trends. DISCUSSION...An organized bowing segment with a history of producing severe winds continues to migrate across south-central IA. However, a decrease in vertically integrated ice, VIL, and echo top height has been noted over the past 30 minutes, suggesting that the severe wind threat may be decreasing in spatial extent and/or intensity to some degree. This is likely attributable to the QLCS meandering into a slightly more stable air mass where daytime heating has been muted due to preceding clouds and light rain. Despite these trends, gradual destabilization continues immediately downstream of the line and ahead of the cold front due to strong low-level warm/moist advection with MLCAPE estimates up to 500 J/kg per mesoanalysis and RAP forecast soundings. The combination of modest destabilization/ascent and favorable deep-layer, line-orthogonal wind shear may maintain the severe wind threat downstream through the remainder of WW 693. Additional watch issuance into southeast/eastern IA remains uncertain and will be conditional on convective trends over the next 1-2 hours. ..Moore.. 10/30/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0348 PM CDT Wed Oct 30 2024 Valid 011200Z - 071200Z Upper-level flow will become quasi-zonal by the end of this week. During the weekend, another strong upper-level trough is expected to dig southward along the West Coast. This feature will then slowly progress to the east into the Plains early next week. Upper-level ridging will build into the West Coast in the wake of the trough. At the surface, high pressure will then build into the Great Basin late this weekend into Tuesday. Thereafter, the upper-level pattern becomes less predictable, though model consensus suggests another trough will move into the West by the middle of next week. ...Northern Mid-Atlantic into Northeast... The cold front expected to pass on Friday appears as though it will not produce much rainfall. A dry airmass behind the front will lead to falling RH values during the afternoon. The surface pressure gradient will be undergoing a slow weakening trend through the day and mixing depths will not be overly high to mix down stronger winds aloft. At least locally elevated conditions are possible and trends in wind speeds will have to be monitored as fuels remain quite dry. ...Southern California... Trends in model guidance have shown the track of the next strong upper-level trough to be farther north than previous days. This trend is noted in both the ECMWF and GFS. This would suggest overall less precipitation potential. That said, offshore winds will increase Sunday night into Tuesday morning which will also include some upper-level wind support. Model trends will continue to be monitored, but current fuel data suggest generally unperceptive fuels and there is still some uncertainty in the stability of these latest model trends. ..Wendt.. 10/30/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
