Clinton Posted December 3, 2020 Report Share Posted December 3, 2020 I like how the 0z handles the mid month storm, time will tell if it ejects from the SW like this. I did envision this storm producing alot of snow in mby, hope it can come a little further north. 2 1 1 Quote Link to comment Share on other sites More sharing options...

westMJim Posted December 3, 2020 Report Share Posted December 3, 2020 Grand Rapids has only officially recorded 0.4" of snow fall so far this winter season. And Grand Rapids is now well past it's average date of its first 1" snow fall. The average date is November 19th. At this time Grand Rapids is now over 7" below average of where we should be at this date. At this time it is mostly clear and 34 here at my house.

Week 2 looks cold and wintry for most of the central/northern Sub.....The Bad??? Week 3-4 have flipped very Warm...MJO has gone into warmer phases... Week 2... Temp & Precip pattern suggesting a colder look that can support a wintry outlook knifing down into the S Plains up into the MW... Week 3-4...The Ugly... Temp and Precip pattern...Blow Torch... The 2nd half of December is highly in question due to a couple of reasons and one being if there is a SSW event. I've learned in the past that during a SSW event the models tend to be erratic. That's not to say they are wrong with their forecast but I've seen them flip back and forth quite often in the LR. The big change in the JMA Weeklies out past Week 2 is the pattern near AK/W NAMER that has a major trough (+EPO). I'm curious to see tonights Euro Weeklies if they to trend this way, if so, then it'll be a brown and warm holiday stretch. On the flip side, it could be a head fake and just another day in the office of analyzing data. Is it believable??? Based on the LRC and the BSR, I'm not completely sold on this idea. Not to mention, the location of the SSW event is in an ideal location and appears to be growing in consensus among the models. Can't script it better than the 00z GEFS below... The Euro weeklies that I posted earlier this week also show blowtorch around/after Christmas. Last year in DSM on the 25th it was 60F. 1 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

The deer have had a lot of fat on them this year. And the buck that I got a couple weeks ago, his fur was really long. Probably one of the best hides I've had yet from a deer. I'm also banking on a tough winter due to the amount of mice I've had since late spring. I've never trapped so many mice in a single year. And the chipmunks were hoarding way earlier than usual.

The years where I noticed we've had bad winters is when acorns barely drop, like this year. The mild winters have tons of acorns, like last year. Personally, I think it's just the calm before the storm. I have a feeling it's going to hit us hard in January, just like it did in 2013-2014. We will have to wait and see!

bud2380 Posted December 3, 2020 Report Share Posted December 3, 2020 A UKMET sighting in an AFD! That's pretty rare. Also an indicator of how boring things are right now that they are talking about potential flurries as the biggest weather impact of the period. The Sunday night time frame `could` be the more favored time for flurries as the strongest forcing and coldest air aloft moves through the area. Interestingly, the UKMET suggests the potential for very minor accumulations. IF this were to occur it would likely be a very dry fluffy snow and any accumulations would be a dusting at best. 1 Quote Link to comment Share on other sites More sharing options...

Thanks Tom for your long range update, actually I only get my longer range thoughts from reading your posts on here the past couple years. Last years longer range forecasts were pretty rough, the cold never showed up like the maps were telling you it seemed. Kind of scary seeing you going with a big warm up and no cold insight for later this month, but, maybe them same maps that showed all that cold that was supposed to be coming last winter that never really showed up and now are showing all this warm air that’s supposedly coming and it to won’t show up. We can only hope they “could” be wrong again and the lower 48 will be flooded with cold and snow in a couple weeks. Please keep up your long range forecasts, again I in joy reading them even if you’re not always 100% with them because let’s be honest, no weather forecaster is always correct! 1 1 Quote Link to comment Share on other sites More sharing options...

Clinton Posted December 4, 2020 Report Share Posted December 4, 2020 Nice AFD from my office. Mentions more active weather later next week. These dry spells are going to be brutal at times, waiting is the hardest part. Model guidance shows this pattern sticking around for several days. A small shortwave trough passes through the area on Sunday, but the lack of moisture curtails any attempts at precipitation. A narrow omega blocking pattern establishes itself over the Eastern Rockies Sunday evening. This halts or deflects any storms systems attempting to move in from the west. As a result, a cutoff low attempts to cross the Western Rockies, but is unable to overcome the blocking ridge. This cutoff low slides south along the Sierra Nevada Mountains and stagnates over Baja California. As the week goes on a wholesale pattern shift weakens the omega block. The jet stream begins to sag south by late next week and sweeps up the cutoff low over Baja California. This accelerates the low across the CONUS and could bring us some more active weather late next week. && 3 Quote Link to comment Share on other sites More sharing options...

They become a problem when people who don't know any better spread them over social media and people act like it's a forecast. 6 Quote Link to comment Share on other sites More sharing options...
