Kmlwx Posted September 1, 2021 Share Posted September 1, 2021 I set my alarm for 2:15 - probably could have snuck another hour or so in at least IMBY. Probably wise to go back to sleep after this stuff passes. Southern end of that cluster is worth watching too. 1 Link to comment Share on other sites More sharing options...

so_whats_happening Posted September 1, 2021 Share Posted September 1, 2021 Working at KBWI right now and watching closely it looks to be going more ENE now we may not get down to the southern end but that is one impressive looking storm for this time of day. 1 Link to comment Share on other sites More sharing options...
SnowenOutThere Posted September 1, 2021 Author Share Posted September 1, 2021 Right under the northern part in Franklin Farm, two huge thunder claps woke me up and then there was just constant lightning (1 per second) and my whole family woke up. Have 2.80 inches of rain and the lightning is now stopping a bit. Whole family has said that they have never seen anything like it and the weird part is that there has been little thunder except if it is super loud. Anyways looks like the storm is just a taste of what's to come. That said there have been near constant spin ups so this shows how any storm even at night can be rotating in this environment, I really hope schools decide to not open today. Also the power has gone off and on three times. Link to comment Share on other sites More sharing options...

Kmlwx Posted September 1, 2021 Share Posted September 1, 2021 Having the TDWRs is so nice in these cases. Though it often seems the TDCA and TADW have trouble seeing up my way in terms of velocity. Link to comment Share on other sites More sharing options...

Kmlwx Posted September 1, 2021 Share Posted September 1, 2021 We've seen LWX warn similar storms. If it keeps up another scan or two I bet it'll get tor warned. Looks decent on the TDWRs AND the KLWX radars. Link to comment Share on other sites More sharing options...

Kmlwx Posted September 1, 2021 Share Posted September 1, 2021 Radar estimates somewhere in the neighborhood of 1.5-2.3 inches fell during that storm IMBY. That's almost as much as some of the models had for me for the entire even - just goes to show you that while global and even mesoscale model output is a good guide - individual cells/clusters can boom or bust your total pretty easily. Add in whatever comes later today (and any showery stuff in between) and we could easily get some beefy rain totals even though guidance had the worst flood threat NW. 1 Link to comment Share on other sites More sharing options...
