SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0229 AM CDT Wed Jun 26 2024 Valid 281200Z - 291200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF SOUTHEAST NE...NORTHEAST KS...CENTRAL/SOUTHERN IA...NORTHERN MO...WESTERN IL... ...SUMMARY... Severe thunderstorms may develop from parts of the central Plains into parts of the upper Midwest and upper Mississippi Valley on Friday. Large hail, damaging wind, and a couple tornadoes will be possible. ...Central/northern Plains into the upper Midwest/Great Lakes... A mid/upper-level trough will move eastward across the northern Great Plains into the upper Great Lakes region on Friday into Friday night. In conjunction with the shortwave, a surface low will move eastward across the Dakotas, with secondary low development possible across the central Plains. A warm front is forecast to move northward across the mid/upper MS Valley, while a cold front will move through the northern/central Plains into MN through the day and into the evening. Widespread convection will likely be ongoing at the start of the period, within a warm-advection regime. In the wake of the morning convection, moderate to locally strong destabilization will be possible in the vicinity of the cold front and a possible outflow boundary across parts of NE/IA into northeast KS/northwest MO, with somewhat more modest destabilization along the northward extension of the front into the eastern Dakotas and parts of MN/WI. The strongest mid/upper-level flow will move across the Dakotas into Minnesota, though modest westerlies farther south will support sufficient effective shear for some storm organization, both in the vicinity of the cold front and any outflow boundaries, and also within the post-frontal regime into parts of the central High Plains. Storm evolution during the afternoon/evening remains somewhat uncertain, but development of a few supercells and/or stronger clusters will be possible, both near the cold front somewhere from southeast NE and IA into northeast KS and northern MO, and also within a potentially favorable post-frontal regime across the central High Plains. Large hail and localized severe gusts will be possible initially, along with some tornado potential, especially if any supercells can develop within a belt of stronger low-level flow/shear currently forecast from eastern KS into northern MO, southern IA, and western IL. Farther north, the magnitude of destabilization remains rather uncertain into the eastern Dakotas and Minnesota, but strong deep-layer shear will support a conditional supercell threat, if sufficient pre-frontal buoyancy develops. A hail and severe-wind threat would accompany any persistent deep convection within this regime. A Slight Risk has been included where confidence is currently greatest regarding storm coverage within a favorable environment, from southeast NE/northeast KS into central/southern IA, northern MO, and western IL. Storm coverage is less certain across the eastern Dakotas and Minnesota, while the corridor of the most favorable post-frontal environment is also uncertain across the central High Plains. Greater probabilities may eventually be needed for those areas as well, depending on the resolution of these uncertainties. ..Dean.. 06/26/2024 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0225 AM CDT Wed Jun 26 2024 Valid 271200Z - 281200Z ...Synopsis... A mid to upper-level shortwave trough, jet max, and associated cold front will pass over the Pacific Northwest and western/northwestern Great Basin Thursday. Although some cloud cover is expected throughout the day, pockets of clearer skies will allow for deeper mixing through the lower troposphere near the Upper Snake River Plain and portions of the northern Great Basin around the UT/NV border. This, along with a tightening surface pressure gradient, will support sustained winds around 25 to 30 mph (with localized gusts up to 40 mph possible) across the Upper Snake Region and 15 to 20 mph winds further south. Warm temperatures and dry boundary-layer conditions near a prefrontal trough axis will also yield RH in the upper to lower teens north to south respectively. ..Barnes.. 06/26/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Fire Weather Outlook CORR 1 NWS Storm Prediction Center Norman OK 0203 AM CDT Wed Jun 26 2024 Valid 261200Z - 271200Z CORRECTED FOR GRAPHIC ...Synopsis... Isolated dry thunderstorms will be possible across portions of the western and northwestern Great Basin as early as this morning. Then, late this morning through this afternoon, additional isolated dry thunderstorms may develop along and east of the Cascades of WA. These areas will also be favored regions for increasing west to southwest sustained surface winds around 20-25 mph via a tightening surface pressure gradient along and just behind a cold front. Clearer skies in the wake of mid-level ascent accompanying a shortwave trough will also allow for deeper mixing/momentum transfer of stronger flow from aloft across these regions. The lowest RH is anticipated over the Great Basin, where low teens should persist throughout most of the day. Further north, east of the Cascades, minimum RH will range from 20-30 percent. ..Barnes.. 06/26/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
