A secondary threat of<br \/>\n  isolated severe wind gusts extends into parts of the southern Plains and from east-central Colorado into northeastern New Mexico.<\/p>\n<p><strong>Key points:<\/strong><\/p>\n<ul>\n<li>Slight Risk (level 2 of 5) covers the Ozarks and mid Mississippi Valley for July 31.<\/li>\n<li>Main hazards are severe wind gusts and hail; isolated severe gusts also possible in the southern Plains and east-central Colorado into northeastern<br \/>\n  New Mexico.<\/li>\n<li>SPC places the damaging wind probability at 15%, large hail at 5%, and tornado probability at 2%.<\/li>\n<li>Storms expected to develop this afternoon and persist into the early to mid evening.<\/li>\n<li>Storm mode includes supercells and organized line segments across the primary risk area.<\/li>\n<\/ul>\n<h2>Where and When Ozarks Severe Thunderstorms Are Expected<\/h2>\n<p>The SPC identifies the western Ozarks as the focal point for storm initiation, with a cold front pushing southeastward into that area ahead of a<br \/>\n  positively tilted shortwave trough dropping through the mid to upper Mississippi Valley. Surface dewpoints in the 70s\u00b0F will fuel an axis of rich moisture<br \/>\n  ahead of the front, allowing moderate to strong instability to build by afternoon. The SPC forecasts mixed-layer CAPE values peaking between 2,500 and<br \/>\n  3,500 J\/kg during peak heating hours.<\/p>\n<p>The primary Ozarks severe thunderstorms risk area runs from southern Missouri northeast across central and southern Illinois, taking in the St. Louis<br \/>\n  metro. Once storms fire, they are expected to track southeastward across the mid Mississippi Valley, and the threat could linger into the early to mid<br \/>\n  evening.<\/p>\n<p>The second area of concern spans parts of the southern Plains, with a cold front dropping southward into central Oklahoma and the Texas Panhandle by<br \/>\n  afternoon. Scattered storms in that region will move south-southeastward across the Red River Valley and southward across the Caprock of west Texas, with a<br \/>\n  separate cluster of isolated severe wind producers possible from east-central Colorado into northeastern New Mexico.<\/p>\n<figure style=\"max-width:420px;margin:26px auto;padding:12px;border:1px solid #d8dde3;border-radius:4px;background:#ffffff;text-align:center;\">\n  <img decoding=\"async\" src=\"https:\/\/ialert.com\/blog\/wp-content\/uploads\/2026\/07\/ialert-ozarks-severe-thunderstorms-wind-risk-july-31-2026.png\" alt=\"Ozarks severe \n  thunderstorms damaging wind risk map showing the 15 percent wind probability over Missouri and Illinois on July 31, 2026\" width=\"458\" height=\"846\" \n  loading=\"lazy\" style=\"max-width:100%;height:auto;border-radius:2px;\"><figcaption style=\"font-size:13px;line-height:1.45;color:#555555;margin-top:10px;text-align:center;\">SPC damaging wind probabilities for the Ozarks severe<br \/>\n  thunderstorms threat on July 31, 2026.

Source: NOAA Storm Prediction<br \/>\n  Center.<\/figcaption><\/figure>\n<h2>Meteorologist&#8217;s Take<\/h2>\n<p>The atmospheric setup driving Ozarks severe thunderstorms today centers on two ingredients working together: strong instability and meaningful wind<br \/>\n  shear. Mid-level flow running westerly at 30 to 35 knots provides enough deep-layer shear for organized storm structures. That shear, combined with 0\u20133 km<br \/>\n  lapse rates peaking near 7\u00b0C\/km, creates the steep low-level temperature drop with height that supercharges downdraft winds. In plain terms, air cooling<br \/>\n  very rapidly as it descends will hit the surface as damaging outflow gusts, making wind the primary concern over hail or tornadoes.<\/p>\n<p>The mixed storm mode, supercells alongside organized line segments, matters because each produces wind damage in a different way. Supercells can drop<br \/>\n  brief large hail and focused damaging gusts along a narrow path. Linear segments spread straight-line wind damage across a much broader swath, which is how<br \/>\n  a single storm complex can rack up dozens of reports in one evening.<\/p>\n<p>In the southern Plains and the Colorado and New Mexico zone, temperature-dewpoint spreads exceeding 40\u00b0F in some locations mean precipitation will<br \/>\n  evaporate heavily on the way down. That evaporation cools the air, makes it denser, and accelerates the downdraft, a process forecasters call evaporative<br \/>\n  cooling. It is why a storm that looks unimpressive on radar out there can still deliver a 60 mph gust at the surface.<\/p>\n<p>SPC uses a five-tier system to communicate severe weather potential. Today&#8217;s Slight Risk is the second of those five categories (level 2 of 5),<br \/>\n  indicating scattered severe storm potential rather than a widespread or extreme outbreak. You can read <a \n  href=\"https:\/\/ialert.com\/blog\/weather-articles\/severe-weather-outlook\/\">how each SPC outlook risk category is defined<\/a> for a closer look at what a<br \/>\n  Slight Risk means operationally. Residents across the risk zone should still take Ozarks severe thunderstorms at this category seriously, because level 2<br \/>\n  of 5 produces destructive localized wind damage every season.<\/p>\n<h2>How to Stay Safe During Ozarks Severe Thunderstorms<\/h2>\n<p>Because damaging wind is the lead hazard in today&#8217;s Ozarks severe thunderstorms, your first priority is getting indoors ahead of any approaching storm.<br \/>\n  Secure or bring inside loose outdoor furniture, canopies, and any lightweight objects that wind could turn into projectiles. Avoid parking under large<br \/>\n  trees, which are the most common source of wind-related damage and injury during convective events like this one.<\/p>\n<p>If hail accompanies a storm cell, move vehicles into a garage or covered structure before storms arrive rather than after. Keep a weather app or <a \n  href=\"https:\/\/ialert.com\/analysis.php#alerts\">active weather alerts<\/a> open on your phone so you receive any Severe Thunderstorm Warning the moment it is<br \/>\n  issued for your county.<\/p>\n<p>Have a plan to move to an interior room on the lowest floor of a sturdy building if a warning is issued. That position offers the best protection from<br \/>\n  both wind damage and any brief spin-up. Mobile homes and vehicles are not safe shelter from 60 to 70 mph straight-line winds.<\/p>\n<h2>Ozarks Severe Thunderstorms FAQ<\/h2>\n<h3>Where is the highest severe weather risk on July 31, 2026?<\/h3>\n<p>The SPC places the highest risk in the Ozarks and mid Mississippi Valley under a Slight Risk, level 2 of 5. Secondary isolated severe wind potential<br \/>\n  exists in parts of the southern Plains and from east-central Colorado into northeastern New Mexico.<\/p>\n<h3>How strong could wind gusts get?<\/h3>\n<p>The SPC does not specify an exact peak gust speed in today&#8217;s discussion, but a 15% damaging wind probability applies within the Slight Risk area,<br \/>\n  meaning there is a 15% chance of a damaging wind report within 25 miles of any point in that zone.<\/p>\n<h3>How large could the hail get with today&#8217;s Ozarks severe thunderstorms?<\/h3>\n<p>Hail is possible but secondary. The SPC sets the large hail probability at 5% for this outlook, where &#8220;large&#8221; means one inch in diameter or greater.<br \/>\n  Supercells could produce hail at or above that threshold, but wind is the dominant hazard today.<\/p>\n<h3>Is there a tornado threat with today&#8217;s Ozarks severe thunderstorms?<\/h3>\n<p>The tornado threat is low. SPC carries a 2% tornado probability, the lowest contoured level, which reflects the chance of a brief spin-up within a<br \/>\n  supercell or along an organized line rather than a meaningful tornado event.<\/p>\n<h3>When will storms develop and move through?<\/h3>\n<p>Storms are expected to develop this afternoon as surface heating peaks, then track southeastward across the mid Mississippi Valley with the threat<br \/>\n  persisting into the early to mid evening hours.<\/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 31, 2026<\/a><\/li>\n<\/ul>\n<div style=\"background:#000000; padding:22px 24px; margin:24px 0; border-radius:4px;\">\n<p style=\"color:#ffffff; font-size:18px; font-weight:bold; margin:0 0 6px 0;\">Get iAlert Notifications for Your Location<\/p>\n<p style=\"color:rgba(255,255,255,0.9); margin:0 0 16px 0;\">The moment a threat is issued for your area, iAlert sends an immediate alert by email, text<br \/>\n  message, or phone call, 24\/7.
