Severe Storms

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0356 AM CDT Mon Jun 10 2024 Valid 131200Z - 181200Z ...DISCUSSION... ...Thursday/Day 4 to Saturday/Day 6... On Thursday, an upper-level trough is forecast to move into the Great Lakes region, as a cold front advances southward across the Central Plains and mid to upper Mississippi Valley. Moderate instability is forecast south of the front by afternoon, where the models suggest that scattered thunderstorm development will take place. In addition, a mid-level jet is forecast to move eastward across the north-central U.S. on Thursday. Moderate deep-layer shear is forecast along the southern edge of this broad mid-level jet, which should support a severe threat during the late afternoon and early evening. On Friday, an upper-level ridge is forecast to move across the north-central U.S. Some models suggest that an axis of maximized low-level moisture will setup beneath the ridge over the central states. If this scenario pans out, then severe storms would be possible Friday afternoon and evening across parts of the central Plains. The presence of the ridge and the lack of large-scale ascent casts doubt on any particular scenario. On Saturday, a shortwave trough is forecast to move into the southern High Plains, as the upper-level ridge moves into the upper Mississippi Valley. In the wake of the ridge, a pocket of moderate instability could be in place across the Dakotas and Minnesota, as is suggested by the ECMWF. This area would be favored for severe storm development. However, uncertainty is still substantial at this range, especially due to significant spread among the model solutions. ...Sunday/Day 7 and Monday/Day 8... On Sunday and Monday, model forecasts suggest that a moist and unstable airmass will be in place across much of the north-central U.S., as multiple short troughs move northeastward through the region. Scattered severe storms will be possible each day ahead of these features in areas that destabilize the most, with the greatest potential likely from Nebraska northward into the Dakotas. However, model spread continues to be large late in the Day 4 to 8 period. Once the model solutions become in better agreement, a 15 percent contour may need to be added in parts of the north-central states for either Sunday or Monday. Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0229 AM CDT Mon Jun 10 2024 Valid 121200Z - 131200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE MID MISSOURI VALLEY NORTHEASTWARD INTO THE UPPER MISSISSIPPI VALLEY... ...SUMMARY... Thunderstorms associated with large hail and severe wind gusts are expected on Wednesday from parts of the mid Missouri Valley northeastward into the upper Mississippi Valley. ...Mid Missouri and upper Mississippi Valleys... West-northwesterly mid-level flow will be in place across the north-central U.S. on Wednesday, as a mid-level jet moves eastward across the far northern states. At the surface, A cold front will advance southeastward through the northern Plains. Ahead of the front, a moist airmass will be in place from the mid Missouri Valley northeastward into the upper Mississippi Valley. Warming surface temperatures and destabilization will likely result in isolated to scattered thunderstorm development during the afternoon. Thunderstorm coverage is expected to increase across the region during the late afternoon and early evening, as low-level flow increases. The exit region of the approaching mid-level jet will also increase large-scale ascent and deep-layer shear, making conditions favorable for organized storms. By late afternoon, the strongest instability is forecast to be from eastern South Dakota into central Minnesota, where MLCAPE is forecast to peak in the 3000 to 4000 J/kg range. NAM forecast soundings along this corridor at 00Z/Thursday have 0-6 km shear in the 40 to 50 knot range, with steep low to mid-level lapse rates. Some soundings suggest that 700-500 mb lapse rates could approach 8 C/km. This environment will be favorable for supercells with large hail. Hailstones greater than 2 inches in diameter will be possible with the strongest of cells. A wind-damage threat will also become likely as the storms gradually grow upscale. Some models suggest that a severe threat could continue into the overnight period, as a cluster remains intact and moves eastward into the western Great Lakes. ..Broyles.. 06/10/2024 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0143 AM CDT Mon Jun 10 2024 Valid 111200Z - 121200Z ...NO CRITICAL AREAS... ...Synopsis... A large-scale ridge will build over the Southwest, favoring increasingly warm/dry conditions across the region -- especially over the Desert Southwest. While surface winds may be slightly more breezy than Day 1/Monday, owing to a weak surface low over southwest AZ, any elevated fire-weather conditions appear too localized for highlights at this time. Farther north, a strong westerly midlevel jet will overspread the Pacific Northwest, while a cold front crosses the region. As a result, breezy west-northwesterly surface winds and locally dry conditions are possible along/east of the Cascades in WA and OR. This combination may yield locally elevated fire-weather conditions, though a limited overlap of the strongest surface winds and low RH precludes highlights at this time (especially given the current state of fuels). ..Weinman.. 06/10/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
