MikeB_01 Posted December 31, 2025 Share Posted December 31, 2025 Looks like the returns are decent behind the initial squall. Could easily pick up 1-2” in a short time. . 1 Link to comment Share on other sites More sharing options...

Rd9108 Posted December 31, 2025 Share Posted December 31, 2025 Looks like the heaviest part of the squall will be here before 1230 so that works. I gotta get up for work early. 1 Link to comment Share on other sites More sharing options...
