Rd9108 Posted 2 hours ago Share Posted 2 hours ago 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...

RitualOfTheTrout Posted 56 minutes ago Share Posted 56 minutes ago 7 minutes ago, colonel717 said: How much do you think you got from the squall Hard to say, its still ripping behind the main line. Id say .5 -.75 in the heart of it. It started out more graupel like, so I knew there was some convective element and a shot at thunder / lightening coupled with the 35dbz returns. I was pushing 4 inches before it hit, will probably get close to 5 for the event. Link to comment Share on other sites More sharing options...

RitualOfTheTrout Posted 32 minutes ago Share Posted 32 minutes ago Looks like one more moderate burst before the dry air starts to shut off the heavier snow. Its ripping here again. Gotta go back outside! 1 Link to comment Share on other sites More sharing options...
colonel717 Posted 26 minutes ago Share Posted 26 minutes ago That was awesome to be out in. I measured 3.5 so the squall gave me over an inch. Still ripping. Link to comment Share on other sites More sharing options...

Wait til that second batch gets to you. Heavy snow, huge dendrites, its a thing of beauty. Phone camera can't do it justice. Link to comment Share on other sites More sharing options...

Most of my memories are from situations like this, usually in a squall line or strong arctic front. Honestly its probably not super rare for our region as a whole in this type of setup. Now getting it as part of a noreaster I can't recall the last time that happened. If I hadn't been outside I would have probably missed it. I'm not sure if there are any official statistics on it or not. Link to comment Share on other sites More sharing options...
