Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0754 PM CDT Wed Aug 07 2024 Valid 080100Z - 081200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PART OF THE CENTRAL HIGH PLAINS AND IN EASTERN NORTH CAROLINA... ...SUMMARY... Scattered strong to severe storms with severe wind gusts and isolated large hail will continue across parts of the central High Plains this evening. An isolated tornado threat will also continue along and near the Atlantic Coast in North Carolina. ...Coastal North Carolina/Far Eastern South Carolina... Tropical Storm Debby will continue move slowly northwestward, moving inland this evening into eastern South Carolina. Rainbands currently extend from near the center of Debby into eastern South Carolina and southern North Carolina. The WSR-88D VWP near Wilmington, North Carolina has 0-1 km storm-relative helicity near 200 ms2/s2 with gradually veering winds in the low to mid-levels. This, combined with surface dewpoints in the upper 70s F, will support a tornado threat this evening. Tornadoes will be possible mainly with cells that can become semi-discrete within the rainbands of Debby. The threat could continue into the late evening and early overnight as Debby moves across South Carolina. ...Central High Plains... The latest water vapor imagery shows evidence of a subtle shortwave trough over the central High Plains. Near this feature, scattered thunderstorms are ongoing from western Nebraska into eastern Colorado. The storms are located along the western edge of a pocket of moderate instability, where the RAP is analyzing MLCAPE in the 1500 to 2500 J/kg range. RAP forecast soundings near the instability axis early this evening have 0-6 km hear in the 30 to 40 knot range, with 700-500 mb lapse rates of 7 to 8 C/km. This will continue to support isolated large hail within rotating cells this evening. Severe wind gusts will also be possible near and just ahead of the more intense line segments. The potential for severe wind gusts should continue for much of the evening as the cluster of storms moves across southwest Nebraska and northwest Kansas. ..Broyles.. 08/08/2024 Read more

MD 1860 CONCERNING SEVERE THUNDERSTORM WATCH 611... FOR CENTRAL HIGH PLAINS
Mesoscale Discussion 1860 NWS Storm Prediction Center Norman OK 0630 PM CDT Wed Aug 07 2024 Areas affected...Central High Plains Concerning...Severe Thunderstorm Watch 611... Valid 072330Z - 080130Z The severe weather threat for Severe Thunderstorm Watch 611 continues. SUMMARY...Hail and wind threat will spread east with convection this evening. DISCUSSION...Water-vapor imagery suggests a weak disturbance may be encouraging upscale convective growth over the central High Plains early this evening. Upper anticyclone remains positioned over the Great Basin and northwesterly 500mb flow should strengthen a bit over northeast CO into western NE tonight. Scattered robust convection is gradually increasing in areal coverage as it propagates downstream into somewhat more buoyant airmass, especially along/south of the synoptic front that currently extends across the NE Panhandle into southeast WY. Prefrontal wind shift is also aiding convection across northeast CO and this activity should gradually advance toward northwest KS later this evening. Several supercells are noted within the larger convective complex, but mixed storm mode should linger for several hours before possible MCS evolves over northeast CO/southwest NE after sunset. ..Darrow.. 08/07/2024 ...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 0458 PM CDT Wed Aug 07 2024 Valid 091200Z - 151200Z In the mid-levels, a belt of modest mid-level flow will remain over the northern half of CONUS through the weekend into early next week. Several shortwave troughs embedded in the flow are expected to provide lift for thunderstorm activity as well as stronger surface winds. One such shortwave trough is expected to traverse the northwestern CONUS with attendant thunderstorm activity. Low precipitable water values may result in a dry lightning risk overlapping with receptive fuels across portions of the northwest and northern Rockies. By early next week, a longwave trough is expected to develop over the northwestern CONUS, with the stronger mid-level flow pushing southward around the periphery of the trough. This may result in some Elevated or Critical fire risk across portions of the Great Basin. At the moment, the highest confidence for overlap of strong winds with low RH and receptive fuels in the region is on D4/Saturday and D6/Monday. Therefore, a 40% highlight has been maintained on D4, and one been introduced on D6 for this area. ..Supinie.. 08/07/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
