Severe Storms

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1243 PM CDT Fri Jun 07 2024 Valid 081200Z - 091200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EASTERN COLORADO EASTWARD ACROSS WESTERN AND SOUTH-CENTRAL KANSAS AND ADJACENT NORTHERN OKLAHOMA... ...SUMMARY... Strong/locally severe storms -- and attendant hail/wind risk -- are expected from afternoon through the evening from the High Plains of Colorado southeastward to the south-central Kansas vicinity. Isolated severe storms will also be possible across the lower Missouri and Mid-Mississippi Valley vicinity. ...Central High Plains southeastward to south-central Kansas/northern Oklahoma... Afternoon heating/destabilization is forecast across the central High Plains -- particularly eastern Colorado and far southeastern Wyoming -- in a post-frontal, upslope-flow environment expected across the area. Isolated storms should develop over the Front Range during the afternoon, and with a rather deep/dry boundary layer that is expected, initially sparse convection should tend to grow gradually upscale through the afternoon. As a cold pool evolves, and given background west-northwesterly mid-level flow atop a developing southerly low-level jet, upscale growth into an east-southeastward-moving MCS appears probable. As such, risk for locally damaging winds, and hail, warrants upgrade to SLGT risk across portions of eastern Colorado and across western and south-central Kansas, reflective of this mainly evening severe-weather potential. Storms will eventually diminish in intensity overnight as the low-level jet veers through the end of the period. ...Southern High Plains... Isolated/high-based afternoon storms are expected to develop over eastern New Mexico and into the Texas Panhandle and South Plains region, near a weak lee trough/dryline, as daytime heating/mixing results in modest CAPE atop the deeply mixed boundary layer. Storms should remain isolated, but evaporative effects within the dry sub-cloud layer could support locally strong/damaging wind gusts with one or two of the strongest storms. Convection should diminish rather rapidly into the early evening, coincident with evening stabilization of the boundary layer. ...Ozarks/Mid-Mississippi Valley area... Ongoing convection/cloud cover is expected early in the period, as a decaying MCS is forecast to be moving southeastward across Missouri. Near and north of an associated west-to-east outflow boundary that should lie across the Ozarks during the afternoon, some potential for warm-advection-induced, isolated storm redevelopment appears possible. Conditionally, the environment would support risk for organized/potentially rotating storms, but with a likely-to-be convectively contaminated boundary layer, and questions regarding storm coverage, will maintain only MRGL risk for severe weather across this area. A few storms may develop nearer the outflow over the southeastern Missouri during the afternoon, and spread across the Mid-Mississippi Valley, but a less-favorable thermodynamic environment with eastward extent should limit severe-weather potential. ..Goss.. 06/07/2024 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1159 AM CDT Fri Jun 07 2024 Valid 071700Z - 081200Z ...Update... A few minor changes were made to the Elevated areas for today. The latest NWP trends suggest a broader area of near critical wind speeds spreading into portions of far southern UT and south central NM. Similarly, dry south-southwest sustained surface winds near 20 mph or slightly greater will precede an area of showers and thunderstorms moving into the TX panhandle early this evening. ERC percentiles across both of the aforementioned regions are beginning to approach or exceed 80-85, and will overlap these hot, dry, and breezy conditions. Yesterday's rainfall across the TX Panhandle, however, has only resulted in a small extension of the Elevated area to the northeast. A small Critical area was considered near and east of the Black Mountains of AZ and Lake Mead region where localized funneling of south winds may occur, but slightly less receptive fuels have precluded the need for this addition. No changes were made to the IsoDryT area, and lightning is already being observed over far southwestern and western NM. Please see the previous discussion for more details concerning thunderstorm potential over the Southwest. Finally, shower and thunderstorm chances will continue to increase over the Florida Peninsula today. Lightning strikes away from heavier precipitation cores could produce fire ignitions, especially over the western-south half of the peninsula, although recent rainfall is beginning to slowly result in relatively less receptive fuels. ..Barnes.. 06/07/2024 .PREV DISCUSSION... /ISSUED 0200 AM CDT Fri Jun 07 2024/ ...Synopsis... Along the western periphery of a mid/upper-level ridge centered over the southern Plains, diurnal heating amid a warm/dry antecedent air mass will yield 10-15 percent RH across much of the Southwest and southern High Plains. Over portions of northern/central AZ into southern NV, a glancing midlevel shortwave trough will promote 15-20 mph sustained south-southwesterly surface winds -- favoring elevated fire-weather conditions (given receptive fuels). Farther east over east-central NM into far west TX, breezy/gusty southerly surface winds will develop in response to a deepening lee cyclone over the central High Plains, which will also contribute to elevated fire-weather conditions during the afternoon. Additionally, a plume of midlevel moisture will remain in place atop the dry/deeply mixed boundary layer across much of the Southwest into the southern High Plains -- with sufficient instability for isolated/widely scattered diurnally driven thunderstorms. Deep inverted-V thermodynamic profiles will favor high-based thunderstorms with limited precipitation potential. As a result, isolated lightning-induced ignitions are possible over the receptive fuels across the region. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Similarly, dry south-southwest sustained surface winds near 20 mph or slightly greater will precede an area of showers and thunderstorms moving into the TX panhandle early this evening. ERC percentiles across both of the aforementioned regions are beginning to approach or exceed 80-85, and will overlap these hot, dry, and breezy conditions. Yesterday's rainfall across the TX Panhandle, however, has only resulted in a small extension of the Elevated area to the northeast. A small Critical area was considered near and east of the Black Mountains of AZ and Lake Mead region where localized funneling of south winds may occur, but slightly less receptive fuels have precluded the need for this addition. No changes were made to the IsoDryT area, and lightning is already being observed over far southwestern and western NM. Please see the previous discussion for more details concerning thunderstorm potential over the Southwest. Finally, shower and thunderstorm chances will continue to increase over the Florida Peninsula today. Lightning strikes away from heavier precipitation cores could produce fire ignitions, especially over the western-south half of the peninsula, although recent rainfall is beginning to slowly result in relatively less receptive fuels. ..Barnes.. 06/07/2024 .PREV DISCUSSION... /ISSUED 0200 AM CDT Fri Jun 07 2024/ ...Synopsis... Along the western periphery of a mid/upper-level ridge centered over the southern Plains, diurnal heating amid a warm/dry antecedent air mass will yield 10-15 percent RH across much of the Southwest and southern High Plains. Over portions of northern/central AZ into southern NV, a glancing midlevel shortwave trough will promote 15-20 mph sustained south-southwesterly surface winds -- favoring elevated fire-weather conditions (given receptive fuels). Farther east over east-central NM into far west TX, breezy/gusty southerly surface winds will develop in response to a deepening lee cyclone over the central High Plains, which will also contribute to elevated fire-weather conditions during the afternoon. Additionally, a plume of midlevel moisture will remain in place atop the dry/deeply mixed boundary layer across much of the Southwest into the southern High Plains -- with sufficient instability for isolated/widely scattered diurnally driven thunderstorms. Deep inverted-V thermodynamic profiles will favor high-based thunderstorms with limited precipitation potential. As a result, isolated lightning-induced ignitions are possible over the receptive fuels across the region. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
