Damaging winds are the primary concern in the<br \/>\n  Southeast this afternoon, while the Dakotas and western Minnesota face a combined threat of damaging winds and large hail later today into the evening.<\/p>\n<p><strong>Key points:<\/strong><\/p>\n<ul>\n<li>Slight Risk (level 2 of 5) covers north Georgia to southern Virginia and the Dakotas into western Minnesota.<\/li>\n<li>Damaging winds are the top hazard in the Southeast; hail and wind threaten the Dakotas and western Minnesota.<\/li>\n<li>SPC hazard probabilities reach 15% for both large hail and damaging winds within risk areas.<\/li>\n<li>Storms are expected this afternoon in the Southeast and this afternoon through evening in the Northern Plains.<\/li>\n<li>A cold front and a closed Canadian low are the main atmospheric drivers for both severe areas.<\/li>\n<\/ul>\n<h2>Southeast Severe Thunderstorms and a Northern Plains Threat: Where and When<\/h2>\n<p>The SPC&#8217;s discussion identifies two geographically separate areas of concern for July 19. In the Southeast, the threat focuses on north Georgia, the Carolinas,<br \/>\n  and southern Virginia, where severe storms are expected to fire this afternoon ahead of a sagging cold front. Farther north, parts of the Dakotas and western<br \/>\n  Minnesota face their own round of severe weather this afternoon and continuing into the evening hours as a closed low digs southeast toward the Upper Midwest.<\/p>\n<p>Both regions sit within the Slight Risk zone, meaning scattered severe storm coverage is likely but a widespread outbreak is not expected. Marginal Risk areas<br \/>\n  buffer the Slight zone on its fringes, indicating that isolated severe storms remain possible even beyond the highest-risk corridors. Travelers and residents in<br \/>\n  all of these corridors should monitor conditions closely throughout the day.<\/p>\n<figure style=\"max-width:1000px; width:100%; margin:1.5rem auto; text-align:center;\">\n  <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ialert.com\/blog\/wp-content\/uploads\/2026\/07\/ialert-southeast-severe-thunderstorms-wind-risk-july-19-2026.jpg\" alt=\"SPC Day 1 wind risk map for \n  July 19, 2026, showing a 15% damaging wind probability for Southeast severe thunderstorms over parts of the Carolinas and a matching 15% wind area across the \n  Dakotas and western Minnesota.\" width=\"1600\" height=\"812\" style=\"width:100%; height:auto; border:1px solid #d0d0d0; border-radius:6px; box-shadow:0 1px 4px \n  rgba(0,0,0,0.12); display:block;\" class=\"size-full wp-image-5365\" srcset=\"https:\/\/ialert.com\/blog\/wp-content\/uploads\/2026\/07\/ialert-southeast-severe-thunderstorms-wind-risk-july-19-2026.jpg 1600w, https:\/\/ialert.com\/blog\/wp-content\/uploads\/2026\/07\/ialert-southeast-severe-thunderstorms-wind-risk-july-19-2026-300x152.jpg 300w, https:\/\/ialert.com\/blog\/wp-content\/uploads\/2026\/07\/ialert-southeast-severe-thunderstorms-wind-risk-july-19-2026-1024x520.jpg 1024w, https:\/\/ialert.com\/blog\/wp-content\/uploads\/2026\/07\/ialert-southeast-severe-thunderstorms-wind-risk-july-19-2026-1536x780.jpg 1536w\" sizes=\"auto, (max-width: 1600px) 100vw, 1600px\" \/><figcaption style=\"font-size:0.85rem; color:#666; margin-top:8px;\">SPC Day 1 wind risk probabilities for July 19, 2026.

To its south, temperatures are climbing into the low-to-mid 90s Fahrenheit<br \/>\n  across north Georgia and the surrounding region, while surface dewpoints sit in the upper 60s to low 70s Fahrenheit. That combination produces a strongly unstable<br \/>\n  air mass, with the SPC&#8217;s HREF ensemble forecasting Mixed-layer CAPE values of 1,500 to 2,000 J\/kg. Precipitable water values exceed 1.75 inches over much of the<br \/>\n  area, with a band topping 2 inches, and sub-cloud lapse rates approaching 8 degrees Celsius per kilometer.<\/p>\n<p>In plain terms, the atmosphere is loaded with moisture and instability, and any thunderstorm that can sustain a strong updraft will be capable of producing<br \/>\n  damaging winds at the surface.<\/p>\n<p>In the Northern Plains, a closed low over the Canadian Prairies is forecast to crest the western ridge and dig southeast toward the Upper Midwest late in the<br \/>\n  day. That approaching upper-level energy, combined with the cold front lifting northward through the Mississippi Valley, will trigger afternoon and evening<br \/>\n  convection across the Dakotas and western Minnesota. This scenario favors both large hail and damaging winds as storms organize in an environment primed by the<br \/>\n  approaching trough. The SPC sets the probability of large hail and damaging winds each at 15% within the risk areas for the event as a whole.<\/p>\n<h2>How to Stay Safe from Damaging Winds and Large Hail<\/h2>\n<p>Because damaging winds and large hail are the named hazards for today&#8217;s Southeast severe thunderstorms and for the Dakotas and western Minnesota, your safety<br \/>\n  actions should center on those specific threats. If a severe thunderstorm warning is issued for your county, move away from windows and seek an interior room on<br \/>\n  the lowest floor of a sturdy building. Wind gusts associated with severe thunderstorms can down trees and power lines rapidly, so stay off roads where possible and<br \/>\n  avoid parking under trees or canopies during active storms.<\/p>\n<p>Large hail can shatter windshields and damage vehicles in seconds. If you are driving and hail begins to fall, pull off the road safely and angle the vehicle so<br \/>\n  hail strikes the front rather than the side windows. Do not leave shelter until the storm has clearly passed and local emergency managers have given the<br \/>\n  all-clear. You can track active severe thunderstorm warnings in real time with <a href=\"https:\/\/ialert.com\/analysis.php#alerts\">iAlert&#8217;s active weather alerts<\/a><br \/>\n  and monitor storm movement on the <a href=\"https:\/\/ialert.com\/analysis.php?tab=radar\">iAlert live radar<\/a>.<\/p>\n<p>With both rounds of Southeast severe thunderstorms and Northern Plains activity expected during daytime hours, conditions can deteriorate faster than the<br \/>\n  average 13-minute warning lead time. Sign up for county-level alerts through <a href=\"https:\/\/ialert.com\/\">iAlert weather alerts and notifications<\/a> so warnings<br \/>\n  reach you wherever you are this afternoon and evening.<\/p>\n<p><strong>Sources:<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/www.spc.noaa.gov\/products\/outlook\/day1otlk.html\" target=\"_blank\" rel=\"noopener\">NOAA Storm Prediction Center, Day 1 Convective Outlook, July 19, 2026<\/a><\/li>\n<\/ul>\n<div style=\"background: #000000; padding: 20px 24px; margin: 20px 0; border-radius: 4px;\">\n<p style=\"color: #ffffff; font-size: 16px; font-weight: bold; margin: 0 0 6px 0;\">Get Severe Weather Alerts for Your Location<\/p>\n<p style=\"color: rgba(255,255,255,0.9); margin: 0 0 14px 0;\">When any NWS watch, warning, or advisory is issued for your area, iAlert sends you an immediate<br \/>\n  notification by email, text message, or phone call, 24 hours a day, 7 days a week.<\/p>\n<p>  <a href=\"https:\/\/ialert.com\/services\/severe-weather-alerts.php\" style=\"background: #C41226; color: #ffffff; padding: 10px 22px; text-decoration: none;\n  border-radius: 3px; font-weight: bold; display: inline-block;\">Sign Up for Severe Weather Alerts &rarr;<\/a>\n  <\/div>\n","protected":false},"excerpt":{"rendered":"<p>Southeast severe thunderstorms threaten damaging winds from north Georgia to southern Virginia on July 19, 2026, while the Dakotas face hail and wind risks.<span class=\"more\"> <a href=\"https:\/\/ialert.com\/blog\/news-events\/southeast-severe-thunderstorms-july-19\/\">Read More&#8230;<\/a><\/span><\/p>\n","protected":false},"author":6,"featured_media":5364,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":"","rank_math_focus_keyword":"Southeast severe thunderstorms","rank_math_title":"Southeast Severe Thunderstorms: 15% Wind Risk Jul 19","rank_math_description":"Southeast severe thunderstorms threaten damaging winds from north Georgia to southern Virginia on July 19, 2026, while the Dakotas face hail and wind risks."},"categories":[719],"tags":[772],"class_list":["post-5362","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-events","tag-spc-outlook"],"acf":[],"_links":{"self":[{"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/posts\/5362","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/comments?post=5362"}],"version-history":[{"count":4,"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/posts\/5362\/revisions"}],"predecessor-version":[{"id":5368,"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/posts\/5362\/revisions\/5368"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/media\/5364"}],"wp:attachment":[{"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/media?parent=5362"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/categories?post=5362"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ialert.com\/blog\/wp-json\/wp\/v2\/tags?post=5362"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
