May go down as one of our all time screams .. and on Christmas Day no less That’s so off. First of all, it doesn’t shape the coastline magically. Second, highest gusts likely just away from shoreline because SSTs will cause an inversion. This event favors hilltops , ridges particularly but also places 10-30 miles inland off the water Link to comment Share on other sites More sharing options...
weatherwiz Posted December 22, 2020 Share Posted December 22, 2020 The big problem with getting maximum wind gust potential with this is the core of the LLJ coincides with the heavy rain. Remember the strongest winds never occur with the heaviest rain. Link to comment Share on other sites More sharing options...

If there was convection involved I could see that potential but I really don't see much convection with this. I wonder what the algorithm is for that product. llvl lapse rates are also pretty junky...appears mostly around or below 5.5 C/KM. tough to really mix down winds when they're that garbage.

Hey the GFS snow map shows 12-18'' but the NAM only shows 3-6''...let's share the GFS map b/c it shows the most snow and everyone gets aroused by hype so let's arouse them. euro showing max wind gusts of 75 mph...NAM only 55 mph...let's show the euro. NAM showing 5000 CAPE, GFS showing 2000...let's show NAM. Everything always has to be the most aggressive, most extreme output. IT's FOOKING RIDICULOUS. WTF IS THE POINT?? Oh here is a SHARPpy sounding that indicates PDS Tornado...I'm going to share that even though what's presented on the sounding is probably more indicative of straight-line winds with a bit of curvature but it's PDS tornado and I want to scare the crap out of people. OUTRAGEOUS. Slightly off topic, but this is what MSM does and it's frustrating. Last night on the 6 PM news a respected news anchor was addressing the very real negative economic impacts due to COVID-19. The example given was a woman who lost her job and took one for far less money, her income dropping from $6,000/month to $255/week. Not $6,000 down to $1,385 or $1,105 down to $255. The impact was huge but IMO the presentation was dishonest and makes one ponder whether other data from that source is similarly spun. I know cold spell wasn't long, but any Hydro issues due to ice jams in the smaller rivers and streams? I don't think there's enough ice - thickness nor extent - to pose a problem, at least in our area. Link to comment Share on other sites More sharing options...

Viewers = money and when it comes to social media platforms likes/follows just equals a big ego. There is obviously nothing wrong with sharing forecast models online, however, the way it's done is just totally irresponsible. The idea should be to use something to emphasize or illustrate what you're trying to forecast. What gets me is when people will post like a snow map that shows 20-30'' and then say "here is one model showing 20-30''. doesn't mean it will happen, and this is only one model"...WTF is the point of the post then? there is no point other than to get views/likes/clicks.

weatherwiz Posted December 22, 2020 Share Posted December 22, 2020 Bufkit (yeah kinda far out) is not very impressed with mixing (BDL). Have to change the value to 20 to really mix down stronger winds. The inversion actually isn't terribly strong though but it certainly doesn't take much of an inversion to prevent deep mixing. I still say we see gusts 40-50 inland. Bigger issue is going to be flash flooding. 1 Link to comment Share on other sites More sharing options...
NW_of_GYX Posted December 22, 2020 Share Posted December 22, 2020 The soaking rains won’t bother me, we get a few of these every winter. And in the hills around me there’s a solid 12-14 inches on the ground that will fully glacierize after this. But man other parts of western and central maine are total snow holes right now. Big inversion at the river today, 5 degrees warmer at the base than in town bethel. It’s so bizarre to see less snow and more grass the further you drive up the access road.

I was actually just thinking about that storm a few minutes ago. The strongest pressure gradient was pretty localized in that storm so it was really SW CT, Long Island, and NYC metro that got hit hard. 1 1 Link to comment Share on other sites More sharing options...
weatherwiz Posted December 22, 2020 Share Posted December 22, 2020 Let's look at the wind potential from the following perspectives: We can "handle" wind events where we gust 40-50 mph. Will this result in some damage? Of course. Will this result in widespread damage? No. Will this result in power outages? Yes Will this result in widespread power outages? No Now, if we get gusts in the 50-70 mph range, well then the answers to all the above are yes. So, what's the likelihood of a 40-50 mph gust event vs a 50-70 mph gust event? Let's assess... What are some of the differentiators between each? Low level lapse rates: In our higher end wind events, there are typically steeper low-level lapse rates present. The steeper the low-level the lapse rate, the greater the depth and strength of mixing. This of course results in stronger momentum transport and tapping into stronger winds. In this event low-level lapse rates likely will be less tan 5.5 C/KM...if even that. This isn't going to get the job done. Convection: The best way to drawn down strong winds is via convection. Outside of the impressive forcing, the signals for convection are very weak. No sfc-based instability, virtually no elevated-instability (or certainly not enough to indicate convection) due to very poor mid-level lapse rates and saturated profile. Dry punch: In these setups, the strongest winds ALWAYS occur outside of the heavier rain. Heavy rain stabilizes the atmosphere and limits mixing. Rain itself does not result in momentum transfer unless there is convection involved. A dry punch (or whatever you want to call it) can help with steepening lapse rates and also enhance mixing. If you look at this setup, the strongest LLJ coincides with the heaviest rain. It will be very stable above the surface and that will make it very difficult to transport much of these winds. Sure even if we "only" tap into a little bit of it we would get crazy gusts but how can we do that in this case...convection. And there isn't much signals for convection. 7 3 1 1 Link to comment Share on other sites More sharing options...
