  1. agree, and for the LOT CWA, the slower timing similar to the 12z Euro would up the ante. Sent from my SM-G998U using Tapatalk
  2. Seriously, it's hard not to get lulled a bit. Thinking back to how things unfolded, it was a dead ringer for me to June 30th 2014, just shifted north. As it turned out, both that event and tonight had quite similar and extremely high end environments. I think we handled the event pretty well, but in hindsight, we could have/should have hit the strong tornado threat harder based on how the environment evolved. Going back to my first statement, I can absolutely say that the first round not producing like we thought it would be capable of changed expectations some for round 2. In that the data pointing to a higher end threat kind of sneaks up on us in a way. It happened with the 2nd derecho on 6/30/14 and in a way did tonight. We were thinking the same thing - we needed the rain, but didn't need *this* to get the much needed rain. Horrible situation, strong QLCS tornado at night in highly populated suburbs when a lot of people are already sleeping going into the work week.
  3. That turned into a night I'll never forget at the weather office to say the least. The tornado tracked just north (less than a mile as the crow flies) from my house and then probably a quarter mile or less from my mother in law's house. A main west east street (Bailey Road) just north of my area has an entire row of powerpoles knocked over along with large trees blocking it. There's a large tree blocking the north south road (Coach Drive) through my subdivision (Naper Carriage Hill). My area was relatively unscathed just south of the tornado circulation where it appears we got the RFD like winds on the south part of the MV, leading to spotty tree damage, though relatively significant in spots. I spoke to someone with Naperville Electric when I was checking out the damage at Coach and Bailey and it sounds like the fairly bad damage goes back to just south of Bailey a bit to the west of Washington Street. Since I can basically roll out of bed to the damage, I might be helping out with the survey. Pretty shook and wired from this experience. It's kind of a helpless feeling when it hits so close to home. But also can say that these are the nights that make this job rewarding as we can literally save lives with the warnings we put out. Hope no one I know doesn't have any friends or family hit by the tornado and that there were no fatalities. I'm also saddened by parts of the town I've called home since I moved out here in July 2010 along with nearby suburbs being struck by terrible damage from this tornado.

  4. We fixed it on Monday. Prior to that, it had been running noticeably warm even at night vs ORD and MDW. Sent from my SM-G998U using Tapatalk
  5. The recorded length of the less than 1/2" precip streak at ORD may have been a bit misleading. Certainly possible one of Jan 30th or Jan 31st had 0.5" liquid equivalent. MDW 3sw COOP had 0.52" on 1/30 and 0.50" on 1/31. Then ORD just missed the higher totals and liquid amounts to its east in Feb. Still an impressively long dry/quiet stretch. We did correct the April CF6 to remove the erroneous TS occurrence on April 5th. Unsure why, but lightning distant in a few of the obs that day at ORD triggered the climate program to call it an on station TS occurrence. Based strictly off the Chicago obs we have, it shattered record for latest into year of a TS occurrence, with previous latest being May 3rd. I'm a bit leery of putting too much stock in it as a record because especially going back to when the official site was not an airport, we don't know what counted as a TS. Is it possible that lightning out over the open waters of the lake counted as a TS? Also even with airport observers, prior to modern remote sensing of lightning and ASOS in the mid 1990s, was there subjectivity in what counted as a TS observation? What we can safely say is that this year by far had the latest first TS at ORD in the ASOS era.
  6. What's become clear is that the outdoor mask mandates were never needed, and likely relied on faulty guidance to justify them. At this point, most adults who wanted to be vaccinated have gotten at least their first dose and a majority of those who haven't probably are hesitant or are straight up anti-vaxxers. The CDC's new guidance finally recognized that we should no longer be tailoring society to protect people who largely don't want to be, or the hypercautious. Particularly outdoors, the vaccinated have essentially zero risk and the unvaccinated have extremely low risk, especially in the warmer months. I doubt many are going to continue to heed outdoor mask mandates and they're not usually enforceable anyway. Indoors will probably be a different story. There may be increased instances of people refusing to wear masks in stores, but I suspect for a while longer that most people will see it as a minor inconvenience not worth causing a fuss over. The indoor mask ordinances do need to be rolled back sooner rather than later though.
  7. You never know with these intense f-gen bands. I think if it snows heavy enough for long enough, a couple sloppy inches on colder surfaces certainly possible. The most likely outcome probably still is mostly white rain aside from a sloppy coating here and there (similar to what 3km NAM has been showing), but will be interesting to see what we wake up to.

  8. Revisiting this, for some reason we weren't included on the SPC collaboration call even though a few of our counties were in the MD. We probably would've been fine adding those few counties into the watch had we been included on the collab call. Sent from my SM-G998U using Tapatalk
  9. The good news for this month vs what happened in 2012 is it'll be cool for the next week and pattern overall is forecast to be on the active side into the medium-long range. If this month doesn't come in at or above normal and the ridge starts to build in June, that would become more problematic. The rain we've gotten here in the southwest suburbs over the past week, while not a lot, has helped keep things pretty green. Sent from my SM-G998U using Tapatalk
  10. June has historically been the most active month locally. Hopefully May picks up after next week and June is rocking. If you can go into June having already had an active season, that's a bonus. Sent from my SM-G998U using Tapatalk
  11. I'll always regret not issuing an advisory on the day shift the afternoon before 4/14/19. Was strongly considering it, but with no buy in from the neighboring offices, opted against it. That was definitely a special case, as it turned out basically every box checked for heavy snow rates and overcoming the warm ground and high sun angle. I see it as a good mental check now when there's a possible solid late season snow event, knowing what went into that event helps the forecast at a challenging time of year to forecast snowfall.

  12. Maybe for the southeast part of the CWA? The other aspect that's part of the headline decision in marginal situations is time of day. It's now after midnight down there, which means much less vehicles on the roads. With no impacts to this evening's commute and snow ending well before the morning commute, can't really justify putting an advisory out for that long. The potential for slick spots can certainly be messaged by various means, such as a Special Weather Statement, graphics, social media posts, retweeting INDOT, etc, without putting an advisory out.
  13. If there were noteworthy road impacts, the case would be more defensible. Any snow higher than a trace today would technically be historic, no? The record for the date was T so if it merely set the new record at 0.1", that warrants an advisory? From the IND Evening Update AFD: "Road impacts appear to be minimal at this time, with the majority of the accumulations occurring on grassy areas." There's really no need for further debate on it, with no real travel impacts, advisories are typically not issued. Certainly some gray area and the product has been more commonly issued for sub-advisory criteria impact-based reasons in recent years, but this event doesn't hit that bar in the Indy area, regardless of the historic nature of the snowfall.
  14. Liking the upstream satellite and radar trends across South Dakota w.r.t. tomorrow locally. Several CG strikes and GLM flashes, and Aberdeen, SD was reporting 1/4SM +SN a couple hours ago.
  15. Really solid f-gen band, snowed hard enough here at LOT that we've been down around 1/2sm visibility and gotten a few tenths on the grass and car tops. Just wet roads and parking lot, though part of the sidewalk outside has a minor dusting. The meso models (aside from the RGEM) and the Euro certainly did best with band placement. Main issue will be that the band is too transient to support any legit accums and impacts. Sent from my SM-G998U using Tapatalk
