Day 1 Convective Outlook AMEND 1 NWS Storm Prediction Center Norman OK 0347 PM CDT Mon May 20 2024 Valid 202000Z - 211200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS THE CENTRAL HIGH PLAINS... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF NORTHERN ILLINOIS AND SOUTHERN WISCONSIN... AMENDED FOR LOWER MICHIGAN ...SUMMARY... The primary threat for severe thunderstorms today will be over parts of the central Plains, with large hail, damaging wind gusts, and a few tornadoes possible. ...20z Update... No changes to forecast reasoning and outlook thresholds for the Plains severe risk -- see previous discussion below. Some spatial adjustments made across southern Wisconsin and northern Illinois for an eastward-shifting severe risk, which includes upward-adjusted probabilities (Slight Risk) across parts of Lower Michigan. ..Guyer.. 05/20/2024 .PREV DISCUSSION... /ISSUED 1133 AM CDT Mon May 20 2024/ ...Central High Plains... A large upper trough will slowly deepen across the western United States today, with strengthening southwesterly mid/upper level flow spreading across the Plains states. A band of mid-level moisture and instability will result in scattered high-based thunderstorms across northern CO/southern WY by mid-afternoon, capable of locally damaging wind gusts. Other discrete supercell storms may form in vicinity of the DCVZ as southeasterly low-level winds and elevated terrain aid in initiation. These storms will track east-northeastward into a progressively more moist/unstable air mass, with the risk of very large hail and a few tornadoes through the evening. By mid-evening, coverage of storms will increase over southwest NE as a southerly low-level jet strengthens, with storms progressing across the central Plains overnight with a continued risk of large hail and damaging winds. ...IL/WI... A well-defined remnant MCV from overnight convection over KS is currently over northeast IA. A surface boundary extends eastward from the low across northern IL. Broken clouds and partial afternoon heating will aid in the development of thunderstorms near the MCV later today as it tracks across southern WI/northern IL. Any storm that can interact with the boundary would have the potential to become a supercell and pose a risk of a tornado or two. Otherwise, hail and gusty winds could occur with the strongest cells. ...Southeast FL... Widely scattered afternoon thunderstorms are possible across southeast FL. Ample low-level moisture, strong heating, cyclonic midlevel flow, and relatively steep lapse rates could result in a strong storm or two capable of gusty winds and hail. Read more

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 268 NWS Storm Prediction Center Norman OK 440 PM EDT Mon May 20 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Western and Central Lower Michigan Lake Michigan * Effective this Monday afternoon and evening from 440 PM until 1000 PM EDT. * Primary threats include... Isolated damaging wind gusts to 65 mph possible Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorms currently moving across Lake Michigan will spread into Lower Michigan soon. A few of the storms may pose a risk of locally damaging wind gusts and hail through early evening. The severe thunderstorm watch area is approximately along and 55 statute miles east and west of a line from 55 miles northeast of Muskegon MI to 15 miles southeast of Kalamazoo MI. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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 267... AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 55 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 25030. ...Hart Read more
