Severe Storms

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1250 AM CDT Mon Jul 07 2025 Valid 071200Z - 081200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER MUCH OF WESTERN/CENTRAL NEBRASKA...SOUTH-CENTRAL SOUTH DAKOTA...NORTHEAST COLORADO...AND FAR NORTHWEST KANSAS... ...SUMMARY... Scattered severe storms are likely across the central into northern Plains. Severe wind gusts and large hail are the main threats. Isolated damaging winds are also possible across parts of the Lower Great Lakes, Upper Ohio River Valley, and the Northeast. ...Central High Plains into the northern Plains... A low-amplitude midlevel trough and related belt of 40-50-kt midlevel westerlies will track eastward across the northern Plains during the day. At the same time, a cold front extending southward from the northern Plains into the central High Plains will move eastward during the afternoon. Thunderstorms are expected at the intersection of the cold front and a lee surface trough over the central High Plains during the afternoon -- aided by peripheral large-scale ascent accompanying the midlevel trough. Ahead of the evolving storms, a corridor of steep midlevel lapse rates/strong surface-based buoyancy and 40-50 kt of effective shear will promote supercells and organized clusters. Large to very large hail and severe wind gusts will be possible with the initial storms. Current indications are that this activity will organize into one or more organized clusters, capable of producing swaths of severe wind (some 75+ mph). Given steep deep-layer lapse rates, lingering surface boundaries, and sufficient hodograph curvature, a couple tornadoes will also be possible. Farther north, stronger forcing for ascent accompanying the midlevel trough will support scattered thunderstorm development along the front from the Dakotas into the Upper MS Valley during the afternoon. Around 40 kt of front-orthogonal deep-layer shear will favor a mix of organized clusters and supercells, capable of producing large hail and severe wind gusts. With time, these storms may grow upscale into an east-southeastward-moving MCS, with an increasing severe-wind risk. ...Upper OH River Valley, Lower Great Lakes, and the Northeast... Widely scattered thunderstorms are expected along/ahead of a slow-moving cold front extending from the Northeast into the Lower Great Lakes/Upper OH River Valley during the afternoon. Around 30 kt of effective shear (stronger over New England) amid a diurnally destabilizing boundary layer will allow for loosely organized multicell clusters capable of producing wind damage. ..Weinman/Guyer.. 07/07/2025 Read more

MD 1586 CONCERNING SEVERE THUNDERSTORM WATCH 489...490... FOR PARTS OF EASTERN COLORADO AND NORTHWESTERN KANSAS
Mesoscale Discussion 1586 NWS Storm Prediction Center Norman OK 0915 PM CDT Sun Jul 06 2025 Areas affected...Parts of eastern Colorado and northwestern Kansas Concerning...Severe Thunderstorm Watch 489...490... Valid 070215Z - 070345Z The severe weather threat for Severe Thunderstorm Watch 489, 490 continues. SUMMARY...The risk of severe wind gusts continues with an evolving cluster of storms. DISCUSSION...At the intersection of two outflow boundaries over far eastern CO, a cluster of thunderstorms is attempting to grow upscale. Over the next couple hours, a 30-kt low-level jet (sampled by the GLD VWP) and around 40 kt of deep-layer shear may promote the maintenance or even slight intensification of the cluster as it tracks slowly southeastward -- especially if it can favorably merge with additional storms/outflow farther south. While gradual nocturnal boundary-layer cooling casts some uncertainty on the potential for additional intensification/organization, the focused low-level jet and modest boundary-layer moisture (upper 50s/lower 60s dewpoints) may offset this to an extent. The primary concern will be severe wind gusts, especially if localized upscale growth can occur. ..Weinman.. 07/07/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 490 SEVERE TSTM KS NE 062140Z - 070500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 490 NWS Storm Prediction Center Norman OK 440 PM CDT Sun Jul 6 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northwest Kansas Far Southwest Nebraska * Effective this Sunday afternoon from 440 PM until Midnight CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Thunderstorms that have developed along an outflow boundary along the Kansas/Nebraska state line should continue to pose a threat for large hail up to 1-2 inches in diameter this afternoon and evening as they spread slowly southward. A cluster of thunderstorms may eventually spread eastward out of Colorado later this evening, with a threat for mainly severe/damaging winds. If this scenario occurs, peak gusts could reach up to 65-75 mph. The severe thunderstorm watch area is approximately along and 45 statute miles north and south of a line from 15 miles west of Goodland KS to 25 miles north northeast of Hill City KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). 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 489... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 30025. ...Gleason Read more

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0756 PM CDT Sun Jul 06 2025 Valid 070100Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE HIGH PLAINS... ...SUMMARY... Scattered storms capable of producing severe wind gusts and large hail will continue tonight across the Plains, especially across eastern Colorado and western parts of Nebraska and Kansas into Oklahoma. ...Discussion... Primary severe risk for the remainder of the night will be focused across the Great Plains, and the central High Plains in particular. Severe potential will continue to nocturnally wane across the Midwest, Maine, and across North Carolina in association with Tropical Depression Chantal. This evening, scattered severe storms including some supercells will persist in areas spanning near the Black Hills southward into the Nebraska Panhandle, eastern Colorado, and western Kansas. One or more semi-organized generally southeastward-moving clusters may eventually evolve within/across the instability axis across far eastern Colorado/western Kansas with an increased severe-wind potential aside from a continued episodic large hail risk. This scenario will be supported by a modestly increasing southerly low-level jet. Damaging winds and some hail will also continue to be a concern across northern Oklahoma with a couple of ongoing clusters, at least for a few hours this evening. ..Guyer.. 07/07/2025 Read more
