Valid 120241Z - 120445Z The severe weather threat for Severe Thunderstorm Watch 484 continues. SUMMARY...The potential for isolated severe wind gusts will continue for the next 1-2 hours. DISCUSSION...Earlier intense thunderstorms that moved through the Tucson area have since weakened, per MRMS reflectivity trends. That observation is consistent with latest objective analysis, which suggests that convective inhibition is increasing across the discussion area. Nonetheless, the existence of an active cold pool and some radar indication of forward-propagational characteristics with the ongoing storms over central Pima County suggest a continued risk for isolated severe wind gusts for the next 1-2 hours as storms move into the western part of the county. ..Mead.. 07/12/2026 ...Please see www.spc.noaa.gov for graphic product...
