Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0100 AM CDT Wed Jul 31 2024 Valid 311200Z - 011200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE MID MISSOURI VALLEY... ...SUMMARY... Scattered thunderstorms with severe wind gusts are expected today into tonight from the central and northern Plains southeastward into the Ohio Valley. Isolated large to very large hail will be possible from parts of the mid Missouri Valley northward into the Dakotas and Minnesota this evening. ...Great Plains/Mid Missouri and Mid-Mississippi Valleys... An upper-level ridge will move eastward into the mid to upper Mississippi Valley today, as an upper-level trough moves into the northern Plains. At the surface, a cold front will advance south and eastward across the Dakotas and Nebraska. A band of strong low-level convergence is expected to develop along the front by midday. This, along with large-scale ascent associated with the approaching shortwave trough, will provide support for scattered thunderstorm development this afternoon. To the east of the front, surface dewpoints in the 70s F will contribute to strong destabilization, with MLCAPE forecast to peak in the 3500 to 4500 J/kg range. This will provide plenty of fuel for MCS development. Cells are expected to first initiate from northern South Dakota into eastern North Dakota. Cell coverage is expected to gradually expand southward into the mid Missouri Valley. Initially, supercell development will be possible in areas that destabilize the most. Strong deep-layer shear and steep mid-level lapse rates will support a large-hail threat. The most intense cells may be able to produced hailstones of greater than 2 inches in diameter, and damaging wind gusts possibly in excess of 65 knots. As low-level flow gradually increases during the late afternoon and early evening, a transition from more isolated convection to a line is expected. The line is forecast to grow upscale and move through far eastern Nebraska and western Iowa, where severe wind gusts will be likely. If a large-scale bow can form, then wind gusts above 70 knots will be possible near the bow's apex. The severe threat is expected to move east-southward into the mid Mid Mississippi Valley during the mid to late evening. Further south-southwest, into the central Plains and southern High Plains, isolated to scattered thunderstorms are expected to develop along and ahead of the front. Deep-layer shear will be strong enough for an isolated severe threat. Large to very large hail will be possible with supercells in parts of central Kansas. However, the environment will be less favorable further southwest with only a marginal severe threat expected in southwest Kansas and the Texas Panhandle. ...Lower Ohio Valley/Southern Appalachians... Northwest mid-level flow will be in place today from the mid Mississippi Valley southeastward into the southern Appalachians. A corridor of maximized low-level moisture will be located from Illinois southeastward into central Kentucky, where strong instability is expected to develop by afternoon. Although there is some uncertainty, several model solutions suggest that an MCS will develop and move southeastward along the instability gradient this afternoon and evening. Forecast soundings in the areas with the strongest instability have substantial directional shear in the boundary layer, with northwest flow at mid-levels. This will be favorable for linear development. A severe threat will be likely with any cold pool that can become established. If a bowing line segment can develop and mature, then wind-damage would be likely along the leading edge. The severe threat should continue into the evening due to the strong instability, with storms eventually affecting the southern Appalachians. ..Broyles/Weinman.. 07/31/2024 Read more

WW 575 SEVERE TSTM TN 310135Z - 310700Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 575 NWS Storm Prediction Center Norman OK 835 PM CDT Tue Jul 30 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Middle Tennessee * Effective this Tuesday night and Wednesday morning from 835 PM until 200 AM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible SUMMARY...Clusters of storms over western Kentucky will sag southward across middle Tennessee over the next several hours. The strongest cores may produce locally damaging wind gusts. The severe thunderstorm watch area is approximately along and 40 statute miles east and west of a line from 10 miles west northwest of Clarksville TN to 80 miles south of Nashville TN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 571...WW 572...WW 573...WW 574... AVIATION...A few severe thunderstorms with hail surface and aloft to 1 inch. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 31025. ...Hart Read more

MD 1758 CONCERNING SEVERE THUNDERSTORM WATCH 575... FOR MIDDLE TENNESSEE
Mesoscale Discussion 1758 NWS Storm Prediction Center Norman OK 1056 PM CDT Tue Jul 30 2024 Areas affected...Middle Tennessee Concerning...Severe Thunderstorm Watch 575... Valid 310356Z - 310600Z The severe weather threat for Severe Thunderstorm Watch 575 continues. SUMMARY...Locally gusty/damaging winds will remain possible along a line of storms moving southward across middle Tennessee. DISCUSSION...A loosely organized line of thunderstorms is moving southward across northern middle Tennessee at 25-30 knots. Local radar depictions recently suggested areas of 30-50 knot low-level winds behind the gust front as the storms tracked through the greater Nashville region. This line will continue to move through a very moist and moderately unstable air mass for several more hours, posing some risk of locally gusty/damaging wind gusts. ..Hart.. 07/31/2024 ...Please see www.spc.noaa.gov for graphic product...
