SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0227 AM CDT Tue Aug 06 2024 Valid 081200Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS THURSDAY ACROSS PARTS OF EASTERN NORTH CAROLINA AND SOUTHEASTERN VIRGINIA... ...SUMMARY... Showers and thunderstorms developing across the coastal plain of eastern North Carolina through southeastern Virginia may be accompanied by potential for a few tornadoes, as Debby moves inland across the south Atlantic coast Thursday. ...Synopsis... Between one prominent mid-level ridge slowly shifting across and east of the Canadian Northwest Territories and another across much of the Southwest into southern Great Plains, mid-level troughing will be maintained along the western and central Canadian/U.S. border vicinity. Within the latter regime, models suggest that a couple of notable perturbations may consolidate near and northwest of the Upper Midwest/Great Lakes vicinity, where a significant low may begin to evolve by Thursday night. At the same time, although some model output still various considerably from others, it appears most probable that the remnant tropical cyclone, approaching the South Carolina coast at the outset of the period, will continue a slow, generally northerly inland progression across the Carolinas. In response to these developments, further low-level cooling and/or drying is likely over much of the interior U.S. during this period, as surface ridging builds southward to the lee of the northern Rockies, through much of the Missouri and Mississippi Valleys. ...Southern Mid Atlantic... Based on the official forecast track and intensity of Debby, which is still expected to be at tropical storm intensity as it migrates inland across eastern South Carolina, it appears that low-level shear will become at least conditionally supportive of convection capable of producing tornadoes in a sector to the north-northeast of the low-level circulation center. Although the degree of boundary-layer destabilization inland of coastal areas remains uncertain, it appears that appreciable low-level buoyancy may develop where surface dew points increase through the mid 70s F+ in advance of the mid-level warm core. It seems possible that this could overspread much of the eastern North Carolina into southeastern Virginia coastal plain during the day Thursday, when daytime heating will maximize potential instability. ..Kerr.. 08/06/2024 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0154 AM CDT Tue Aug 06 2024 Valid 071200Z - 081200Z ...Synopsis... ...Isolated Dry Thunderstorms... Isolated dry thunderstorms will continue across portions of southern Utah, northwestern Colorado, and south-central Wyoming. A plume of mainly mid-level moisture, with precipitable water values around 0.50-0.75, will support high-based convection with little measurable rainfall, amid receptive fuels. Gusty and erratic outflow winds will be possible near thunderstorms. ...Wind/Dry... Enhanced mid-level westerly flow will remain over the Snake River Plain on Wednesday. Deeply mixed profiles will support downward mixing of flow aloft and sustained surface winds 15-20 mph. This will overlap with relative humidity reductions to 10-15 percent and receptive fuels supporting inclusion of an Elevated risk area. ..Thornton.. 08/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0124 AM CDT Tue Aug 06 2024 Valid 061200Z - 071200Z ...Synopsis... ...Isolated Dry Thunderstorms... A shortwave trough will bring forcing for ascent into the northern and central Rockies today. Mid-level moisture above drier boundary-layer conditions will favor dry thunderstorm chances, with little wetting rainfall expected. Fuels from southwestern MT, southeastward into WY, eastern UT, and northwestern CO are sufficiently dry for new lightning ignitions. In addition, gusty and erratic outflow winds will be possible with any stronger storms that develop. ...Elevated Fire Weather, Snake River Plain Idaho... As the shortwave advances across the northern/central Rockies, a band of enhanced mid-level westerly flow will overspread portions of Idaho and Montana this afternoon. An increase in winds is expected across the Snake River Plain, where relative-humidity reductions to 10-15 percent will overlap sustained winds 15-20 mph. Occasional localized critical conditions may be possible. Overall, this looks to be too localized to include an area with this outlook. ..Thornton.. 08/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
