Severe Storms

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1229 PM CDT Wed Aug 28 2024 Valid 291200Z - 301200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF MINNESOTA...WESTERN WISCONSIN AND NORTHERN IOWA... ...SUMMARY... Severe thunderstorms are possible on Thursday from portions of the Upper/Middle Mississippi Valley to the central Plains. A few severe storms also will be possible over portions of the mid-Atlantic region. ...Synopsis... A weak upper-level short-wave trough will shift east across the Northeast on Thursday, as a much stronger trough/low will continue to advance into/across the north-central states. At the surface, a cold front is forecast to sag southward across the Mid-Atlantic region in lee of the Appalachians, while a more prominent cold front shifts eastward/southeastward across the central and northern Plains. ...Mid and Upper Mississippi Valley area to the central Plains... Large scale ascent with the upper low/trough will increase in the vicinity of the eastward-advancing cold front over MN/northern IA, augmented by the right-entrance region of a 250-mb jet lifting north during the day. Substantial instability should be in place by afternoon, with afternoon MLCAPE in excess of 3000 J/kg expected. Strengthening mid-level flow with the approach of the upper trough will contribute to deep-layer shear of 35-45 kts, supporting organized storms including the potential for supercell structures. Thunderstorms should increase in coverage through the afternoon and evening, becoming more linear with time along the cold front. Damaging winds and large hail will be the primary severe hazards, with the severe risk continuing into the evening hours. Some tornado risk may also develop with embedded QLCS circulations as low-level shear appears supportive, especially within the Slight Risk area. Both instability and shear will diminish with southward extent across eastern NE/northern KS, however afternoon thunderstorm development is expected along the front within a largely uncapped environment. Isolated damaging winds will be the primary risk as strong boundary-layer heating will steepen low-level lapse rates, and storms begin to cluster during the late afternoon/evening. Instances of large hail will also be possible. ...Mid-Atlantic Region... A southward-moving cold front will move across the mid-Atlantic in the lee of the Appalachians Thursday within a moderately unstable though weakly sheared environment. With minimal afternoon CINH, thunderstorms should develop over the higher terrain and along the front and tend to cluster with time. This will result in a risk for damaging gusts, and perhaps hail with the stronger updrafts. ..Bunting.. 08/28/2024 Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1223 PM CDT Wed Aug 28 2024 Valid 291200Z - 301200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains on track. ..Weinman.. 08/28/2024 .PREV DISCUSSION... /ISSUED 0152 AM CDT Wed Aug 28 2024/ ...Synopsis... Upper ridging will build over the Interior West as a mid-level trough impinges on the Upper Mississippi Valley tomorrow (Thursday). As a result, surface high pressure and associated quiescent fire weather conditions will settle over the northern Rockies into the Great Basin and Four Corners regions. 15-25 percent RH will be common across much of the Intermountain West by afternoon peak heating, with stronger gusts most likely in localized, terrain-favoring areas. ...Please see www.spc.noaa.gov/fire for graphic product...

A mid-level trough will traverse the northern Rockies today, encouraging strong surface lee troughing over the northern Plains. By afternoon, isallobaric and downslope flow will promote dry and windy conditions over portions of the central and northern Rockies. 15-25 mph sustained west-southwesterly surface winds will overlap with 15-20 percent RH, from portions of southeast Montana into central Wyoming. Elevated highlights have been maintained in central Wyoming, where dry and windy conditions will best overlap with fuels that are at least marginally receptive to wildfire spread. ...Please see www.spc.noaa.gov/fire for graphic product...
