MD 1681 CONCERNING SEVERE THUNDERSTORM WATCH 515... FOR PARTS PF CENTRAL WYOMING
Mesoscale Discussion 1681 NWS Storm Prediction Center Norman OK 0756 PM CDT Tue Jul 15 2025 Areas affected...parts pf central Wyoming Concerning...Severe Thunderstorm Watch 515... Valid 160056Z - 160230Z The severe weather threat for Severe Thunderstorm Watch 515 continues. SUMMARY...A small cluster of thunderstorms may pose a continuing risk for severe hail and wind east of Lander toward areas near and south of Casper through 8-9 PM MDT. DISCUSSION...A small cluster of thunderstorms is maintaining intensity east of Lander and appears supported by low-level updraft inflow emanating from a well mixed boundary-layer characterized by CAPE on the order of 500-1000 J/kg. Objective analysis and model output suggest this environment extends in a narrow corridor across and southwest of Casper, into the western slopes of the Laramie Mountains. Although westerly deep-layer mean flow is weak, this is partially due to pronounced veering from low-level easterlies to mid-level westerlies, with Rapid Refresh forecast soundings from around Casper indicating some strengthening of wind fields contributing to strong shear during the next couple of hours. ..Kerr.. 07/16/2025 ...Please see www.spc.noaa.gov for graphic product...

Scattered severe gusts (some 75+ mph) and large hail are probable across parts of central Nebraska this evening. Isolated severe gusts are also possible from the Upper Midwest to Utah and Wyoming through mid-evening. ...SD/NE... An organized linear MCS has become established from eastern SD into central NE. These storms have product several reports of locally damaging winds and some large hail. This QLCS will progress east-southeastward through the evening into western IA and southeast NE, with a continued severe threat. Reference MCD #1679 and WW #514 for further details. ...Northern WY/Western Upper MI... A line of intense thunderstorms is tracking eastward along and south of the WI/Upper MI state line.

Reference WW #513 for further details. ...WY... Scattered high-based thunderstorms continue to develop and spread across much of western and central WY. The strongest cells in this area will maintain some risk of damaging wind gusts for a few more hours until diurnal cooling diminishes the threat. Reference WW #515 for further details. ...Southeast AZ... Scattered thunderstorms continue to develop in a warm/moist environment over southeast AZ. This activity will slowly build westward for the next several hours, with a risk of gusty/damaging winds. Reference MCD #1680 for further details. ..Hart.. 07/16/2025 Read more
