Mesoscale Discussion 2223 NWS Storm Prediction Center Norman OK 0656 PM CDT Tue Oct 03 2023 Areas affected...eastern NE...southeast SD...southwest MN...and far western IA Concerning...Severe Thunderstorm Watch 699...701... Valid 032356Z - 040130Z The severe weather threat for Severe Thunderstorm Watch 699, 701 continues. SUMMARY...Ongoing storms will continue to grow upscale into a QLCS. The risk for winds and a brief tornado or two will continue. DISCUSSION...As of 2345 UTC, regional radar analysis shows much of the storms over NE and SD have grown upscale into a QLCS. Ahead of this line, the environment remains weak to moderately unstable, sufficient for storm maintenance. Moderate deep-layer vertical shear will continue to support storm organization within the QLCS. The linear mode will support a risk for damaging winds (some 70+ mph), especially with any sustained bowing segments or embedded supercells. Low-level shear should also increase into this evening as the low-level jet strengthens over eastern NE and far southeast SD. Area VADs already show initial signs of this with enlarging low-level hodographs below 1 km. While storm mode and boundary-layer RH are not optimal, a tornado or two will remain possible with embedded supercells or QLCS features this evening. Severe trends will be monitored over the next couple of hours for any local extension of WW701 eastward ..Lyons.. 10/03/2023 ...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 0341 PM CDT Tue Oct 03 2023 Valid 051200Z - 111200Z A strong upper trough will develop within the Upper Midwest through the remainder of this week before moving into the Northeast and becoming a large upper-level low this weekend. In the West and Plains, upper-level ridging will develop. Models indicate some potential for a trough to move into the West Coast early next week. At the surface, a cold front will move through the southern Plains and eventually the Gulf/Mid-Atlantic Coasts by the weekend. High pressure will be present in the Great Basin with some modest reinforcement this weekend as a stronger surface high moves south into the Plains. Given the precipitation and cooler temperatures expected with the frontal system in the Plains into the Mississippi Valley, potential for critical fire weather is expected to remain low during the period. Some weak offshore flow is still possible in southern California, which should peak Wednesday morning. Fuel conditions remain rather moist and only locally elevated conditions are anticipated. ..Wendt.. 10/03/2023 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Issued at 300 PM MDT Tue Oct 03 2023 899 WTPZ45 KNHC 032042 TCDEP5 Tropical Storm Lidia Discussion Number 3 NWS National Hurricane Center Miami FL EP152023 300 PM MDT Tue Oct 03 2023 Lidia continues to exhibit a curved band on geostationary and microwave satellite imagery this afternoon. Deep convection is predominately developing to the west of the low-level center due to the influence of moderate easterly vertical wind shear. The initial intensity is held at 35 kt for this advisory in agreement with the subjective Dvorak intensity estimates from TAFB and SAB, and the objective intensity estimates, ADT and AiDT from UW-CIMSS. The system is moving northwest at 320/7 kt around the southwestern edge of a mid-level ridge located over Mexico. A mid- to upper-level trough to the northwest will begin to weaken the ridge allowing Lidia to move northwest to north-northwest during the next 48 hours. Most models are now in agreement with a more westward motion in Lidia between 48 and 72 hours. There are large differences in the speed of the system, with the UKMET accelerating towards the west faster than the other global models. The forward speed of the system was adjusted slightly faster for this advisory in the short term, and the track forecast is in line with the simple consensus aids. Lidia is still battling some moderate easterly vertical wind shear. The ECMWF/GFS SHIPS guidance depicts that moderate shear will remain over the system throughout much of the forecast period despite otherwise favorable environmental conditions. The guidance for RI continues to lessen the probability with this cycle. The GFS, HWRF, and SHIPS models still strengthen Lidia into a hurricane beyond 2 days, however much of the other guidance, including the HAFS models, does not intensify Lidia as much. The NHC intensity forecast was lowered slightly from the previous advisory and continues to show gradual strengthening to a hurricane by day 5.

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0250 PM CDT Tue Oct 03 2023 Valid 032000Z - 041200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF WESTERN/CENTRAL KS AND SOUTH-CENTRAL NE... ...SUMMARY... Scattered severe thunderstorms capable of producing very large hail, damaging wind gusts, and perhaps a few tornadoes should occur this afternoon and evening, centered on the central Plains. ...20Z Update... The only appreciable change with this update was to expand probabilities slightly westward across western KS. A moist and unstable airmass is present along and east of a cold front across the central Plains. Scattered severe hail should continue to be the main threat in the short term with multiple supercells that have developed across parts of western KS into southwestern NE. Damaging winds may become an increasing concern later this afternoon and evening as convection should attempt to grow upscale into a small bowing cluster along/near the cold front in NE. The threat for a few tornadoes is less clear, as low-level moisture remains somewhat limited. Still, some chance may exist with any supercell that can remain discrete through the early evening, as low-level shear gradually increases in tandem with a modestly strengthening low-level jet. ..Gleason.. 10/03/2023 .PREV DISCUSSION... /ISSUED 1130 AM CDT Tue Oct 03 2023/ ...Central Great Plains... Multiple rounds of scattered to widespread thunderstorms are expected this afternoon and evening, yielding a messy, multifaceted severe weather scenario. Initial ascent along the leading edge of the High Plains buoyancy plume has supported persistent shower and isolated thunderstorms from the eastern OK Panhandle to the north-central KS/south-central NE border area. Most 12Z HREF guidance suggest intensifying thunderstorms will probably evolve in the immediate wake of this activity with the bulk of greater destabilization occurring to its west amid steepening mid-level lapse rates, with decreasing buoyancy ahead of it. Modest mid-level lapse rates and inverted-v low-level thermodynamic profiles downstream should support a threat for mostly isolated severe hail and wind along the leading edge. There will be potential for more intense supercell development along the southwest backside of this initial lobe, around the southwest to south-central KS vicinity, as a plume of MLCAPE from 2000-2500 J/kg impinges on this region from the eastern TX Panhandle and western OK. This could favor a threat for isolated very large hail up to baseball size during the late afternoon to early evening. The primary lobe of ascent attendant to the shortwave impulse ejecting onto the central High Plains from the Front Range should initiate scattered thunderstorms in a few hours as it impinges on the buoyancy plume. This activity should further intensify along the surface front across far northeast CO and northwest KS into central NE later this afternoon. A plume of upper 50s to low 60s surface dewpoints and steep mid-level lapse rates will support supercells conditionally capable of producing significant severe hail. However, consensus of CAM guidance suggests relatively quick upscale growth may occur given the strong forcing for ascent and deep-layer shear vector generally paralleling the surface front. In addition, the gap between these front-aided storms and those within the downstream warm-advection plume should shrink during the evening, further lowering confidence on sustaining discrete supercells. A mix of large hail and severe wind gusts should be the main threats, with convection weakening to the north and east given the expected sharpness of the instability gradient towards the Mid-MO Valley. ...Southern Great Plains... Isolated to scattered thunderstorms appear most probable along the trailing periphery of the KS convective plume into northwest OK, and separately near the dryline in the Permian Basin vicinity during the late afternoon and farther northeast into northwest TX this evening. Mid-level lapse rates with southern extent will be increasingly modest relative to typical severe weather setups along the dryline, suggesting that hail magnitudes may struggle beyond golf ball size. A more favorable wind profile/lapse rate combination for significant severe hail will exist in the eastern TX Panhandle and western OK vicinity, but storm coverage is more questionable here. Overall, there will be sufficient vertical shear/buoyancy for splitting supercells capable of producing large hail and localized severe wind gusts through late evening. ...South-central ND vicinity... A corridor of weak surface-based buoyancy should develop downstream of a shortwave impulse gradually shifting east from the MT/WY/Dakotas border area. Steep mid-level lapse rates and elongation to the hodograph within the upper portion of the buoyancy profile could support a few cells producing marginally severe hail during the late afternoon to early evening.

Mesoscale Discussion 2212 NWS Storm Prediction Center Norman OK 0549 PM CDT Mon Oct 02 2023 Areas affected...portions of the western TX Panhandle Concerning...Severe potential...Watch possible Valid 022249Z - 030015Z Probability of Watch Issuance...40 percent SUMMARY...Ongoing strong to severe storms in eastern NM may pose a risk for damaging gusts and hail into portions of the western TX Panhandle and south Plains this evening. A new watch is possible, but uncertain. DISCUSSION...As of 2235 UTC, regional radar analysis showed scattered severe storms, including a few supercells, ongoing across parts of far eastern NM. Occasional severe gusts and hail have been occurring with this convection as it slowly tracks east/northeast toward the TX border. Thus far, the strongest vertical shear (observed from area VWPs and SPC SFCOA) has remained on the NM side of the border given the mostly meridional deep-layer flow. However, some of the stronger flow aloft may gradually shift eastward into the far western TX Panhandle and south Plains over the next couple of hours. The environment remains broadly favorable along the NM/TX border for storm organization into supercells with 1000-1500 J/kg of MLCAPE and 35-45 kt of effective shear. However, the severe threat likely decreases rapidly beyond the first row or two of counties in TX, with much weaker vertical shear and buoyancy in place over the central Panhandle. While uncertain, a few storms may pose enough of a severe risk that a new small weather watch is possible. ..Lyons/Edwards.. 10/02/2023 ...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 0336 PM CDT Mon Oct 02 2023 Valid 041200Z - 101200Z A broad trough currently in the Great Basin will continue to move east and lose amplitude through the middle of the week. Another reinforcing trough will dig southward out of Canada into the northern Plains/Upper Midwest. The trough will intensify in the Upper Midwest before becoming a strong upper low in the Northeast by the weekend. Ridging will build into the West over the next couple of days before slowly moving to the east. At the surface, the seasons first strong cold front will move into the Plains on Wednesday and eventually reach the Gulf/Southeast coasts by the weekend. High pressure will intensify in the Great Basin and Plains behind the front. Areas with the driest fuels from the Plains into the Mississippi Valley are expected to see some amount of precipitation along with cooler temperatures as the front progresses to the southeast. These conditions should keep potential for critical fire weather low during the extended period. ...Southern California... A warming and dry trend can be expected beginning Tuesday. Weak offshore flow is also expected to develop and peak Wednesday and Thursday mornings. While some drying of fuels will occur, the current state of fuels does not suggest much more than locally elevated conditions occurring. Barring any significant changes in fuel dryness over the next few days, the potential for critical fire weather continues to appear low. ..Wendt.. 10/02/2023 ...Please see www.spc.noaa.gov/fire for graphic product...
