MN Transplant Posted August 20, 2019 Share Posted August 20, 2019 Triple point boundary collision right at the bend of 495 in Annandale. See if anything comes of it. Great Falls getting hit. Again. Link to comment Share on other sites More sharing options...
CAPE Posted August 20, 2019 Share Posted August 20, 2019 If you are not getting a storm now you probably won't see anything for the rest of the evening. The ongoing cells will likely weaken and die in place as we lose the daytime heating. Tired of these storms that fire on localized boundaries in a weakly forced environment. No trigger here away from the bays, and not close enough to the weak, diffuse boundary to the south and SW. That cold front better deliver something. 1 Link to comment Share on other sites More sharing options...

WeatherLovingDoc Posted August 20, 2019 Share Posted August 20, 2019 Last night at 11:08 pm Alexandria Va residents received a Severe Weather Warning via NWS. It woke me up and I alerted my kid. Nothing happened. Today (8/20/19 at 5:34 pm) we received another NWS Severe Thunderstorm Warning. "Seek indoor shelter immediately". So far nothing. Is the NWS crying wolf to soon? Or too much? Serious question. Link to comment Share on other sites More sharing options...

Is the NWS crying wolf to soon? Or too much? Serious question. The problem with this kind of storm setup is that there is a lot of heat/moisture to fuel the storms, but the triggers are very subtle. Unlike a squall line or supercell where movement can be counted on, these cell just kind of ooze around and then die out. So, putting up a warning box is especially tough. The storm last night looked really healthy, and 30 min late it was remnant clouds. Nature of the beast. Not to mention, the areas that get hit by severe conditions are almost always very small. 3 Link to comment Share on other sites More sharing options...
das Posted August 20, 2019 Share Posted August 20, 2019 Dime sized hail Link to comment Share on other sites More sharing options...
09-10 analogy Posted August 20, 2019 Share Posted August 20, 2019 Honestly that was about as impressive as anything I can remember since the derecho. Dime-sized hail, winds well into the 50s (times like this I wish I had an anemometer, even a cheap handheld one), lots of CG, torrential rain. Had it all. Another one incoming. While driving I saw a couple of streets cordoned off (I'm assuming downed trees) and lots of small branches and foliage littering the streets. I have power but a good bit of the Tenleytown area doesn't. Second significant hailer (well, for around here) this season. At least dime size won't dent up the car like the larger hail from June 2 did. Nice to be in the sweet spot for a change. My subjective take is that upper NW has been kinda fringed a lot this season. But we were evidently bullseyed today. 1 Link to comment Share on other sites More sharing options...

I understand what you are saying. I've been watching weather for years. But I am concerned for our populous,youth/younger people who may become "use to these local warnings" which do not pan out or are given too frequently .Imho, better to alert to the following as my best friend did: "On June 29, 2012, a devastating line of thunderstorms known as a derecho (deh REY cho) moved east-southeast at 60 miles per hour (mph) from Indiana in the early afternoon to the Mid-Atlantic region around midnight.

I think most people on this board would agree we have had an exceptionally long and active severe season this year... well into August now. Just because your back yard got missed by a couple miles a handful of times, doesn't mean Sterling isn't doing their job well. A warning is just that.. a warning. They are telling you there is potential in your area for severe weather. It's up to the individual to look at radar, a weather app, or the sky. People need to take some personal responsibility for their safety. If someone deems it a false warning for their backyard then so be it. You can't blame that on NWS. You aren't required to take their advice. As a "youth" I can tell you I'm very appreciative when my phone has a message that pops up saying I just got boxed for severe. I don't think anyone is crying wolf. I think we're just witnessing the natural progression of forecasting which is higher detail on a smaller scale. There are inherently going to be more "misses" with that approach because of the increased volume... but it's more accurate overall. Link to comment Share on other sites More sharing options...
WeatherLovingDoc Posted August 20, 2019 Share Posted August 20, 2019 As a follower of American Weather, I applaud you all. But I will say again, too many "wolf cry's at all hours on iPhone/Samsung will negate the benefit. Our "youth" are different. Link to comment Share on other sites More sharing options...
