Severe Storms

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1230 PM CDT Sat Jun 28 2025 Valid 291200Z - 301200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE UPPER MIDWEST INTO THE LOWER MISSOURI VALLEY... ...SUMMARY... Scattered strong to severe storms are possible Sunday from the central Plains into the upper Great Lakes region, with some potential for the evolution of a large, organized severe storm cluster across parts of the mid into lower Missouri Valley and central Great Plains late Sunday through Sunday night. ...Synopsis... An amplifying midlevel trough will advance east-southeastward from the north-central Plains toward the Upper MS Valley through the period. Related large-scale ascent will overspread the Middle/Upper MS Valley, while a related cold front moves southeastward across the region. ...Upper Midwest... In the wake of several overnight storm clusters and related cloud debris, gradual clearing should support boundary-layer destabilization and the development of moderate-strong surface-based buoyancy. As the cold front intercepts this increasing buoyancy, around 30 kt of deep-layer shear should favor a few organized clusters capable of producing widely scattered damaging wind gusts during the afternoon. ...Central Plains to the Middle/Lower Missouri Valley... A separate area of thunderstorms is expected along the front in IA and the Lower MO Valley during the late afternoon into the overnight hours. Ahead of these evolving storms, lower/middle 70s dewpoints beneath steep midlevel lapse rates will contribute to strong-extreme surface-based buoyancy. Initial storms will be capable of producing isolated large hail and locally severe wind gusts. However, strengthening deep-layer shear accompanying the digging midlevel trough, coupled with an increasing low-level jet, will support the development of a southward-moving MCS into the overnight hours. The Slight risk was expanded southward to account for this scenario, and higher wind probabilities may eventually be needed as the scenario becomes more clear. Farther west, semi-discrete storms are expected over the central High Plains during the afternoon. Elongated/straight hodographs and moderate surface-based buoyancy should favor large hail with any supercell structures that can develop. ...Mid-Atlantic... Despite marginal deep-layer flow/shear, diurnal heating amid deep tropospheric moisture (around 2 inch PW) will favor wet microbursts and the potential for wind damage with the stronger thunderstorms. ..Weinman.. 06/28/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1153 AM CDT Sat Jun 28 2025 Valid 281700Z - 291200Z ...Snake River Plain... A broad area of elevated mid-level winds on the southern periphery of a mid-level trough along with daytime boundary layer mixing will support breezy winds across the Snake River Plain this afternoon. Elevated highlights were trimmed across portions of the Magic Valley Region owing to a now marginal overlap of winds and low relative humidity based on the latest model guidance consensus. ...Southwestern Wyoming... Only minor changes were noted to Elevated highlights across southwestern Wyoming. Increased mid-level flow coupled with lee troughing farther east will enhance westerly winds across the area. The breezy winds combined with dry fuels and relative humidity dropping into the 15-20 percent range will promote elevated fire weather conditions this afternoon. ..Williams.. 06/28/2025 .PREV DISCUSSION... /ISSUED 0203 AM CDT Sat Jun 28 2025/ ...Synopsis... Subtle mid-level troughing on the northern periphery of the sub tropical ridge will continue over the northern Rockies and Northwest today. A belt of stronger mid-level flow will remain in place over parts of the Intermountain West, supporting dry downslope flow ahead of a weak cold front over the Northwest. Lee troughing and the increased flow aloft will encourage breezy westerly flow amid dry conditions, conducive for elevated fire-weather conditions. ...Snake River Plain into western WY... Increasing mid-level flow attendant to a passing mid-level shortwave trough will overspread a dry and well-mixed boundary layer across portions of ID and western WY this afternoon. Aided by lee troughing, elevated surface winds are expected across the central/eastern portions of the Snake River Plain and through the Red Desert in southwest WY. Westerly winds of 15-20 mph, combined with warm afternoon temperatures and relative humidity in the 15-20 percent range, will support elevated fire weather conditions this afternoon and evening. ...Please see www.spc.noaa.gov/fire for graphic product...

Subtle mid-level troughing on the northern periphery of the sub tropical ridge will continue over the northern Rockies and Northwest today. A belt of stronger mid-level flow will remain in place over parts of the Intermountain West, supporting dry downslope flow ahead of a weak cold front over the Northwest. Lee troughing and the increased flow aloft will encourage breezy westerly flow amid dry conditions, conducive for elevated fire-weather conditions. ...Snake River Plain into western WY... Increasing mid-level flow attendant to a passing mid-level shortwave trough will overspread a dry and well-mixed boundary layer across portions of ID and western WY this afternoon. Aided by lee troughing, elevated surface winds are expected across the central/eastern portions of the Snake River Plain and through the Red Desert in southwest WY. Westerly winds of 15-20 mph, combined with warm afternoon temperatures and relative humidity in the 15-20 percent range, will support elevated fire weather conditions this afternoon and evening. ...Please see www.spc.noaa.gov/fire for graphic product...
