Minny_Weather Posted October 20, 2020 Report Share Posted October 20, 2020 Frontogenesisssssss! Quote WEDNESDAY NIGHT INTO THURSDAY...Concern continues to be the threat of significant snowfall as a surface low pressure traverses the northern Great Plains beneath an open upper level shortwave trough/vorticity maxima. This surface low will provide a large swath of warm air advection over the northern Great Plains with ample moisture content, providing the threat for snow. Where questions start to arise is if mesoscale features will play a role in stronger snow totals. Ensemble guidance hints at the potential for 700mb closing of the system, which could provide for frontogenetic forcing opportunities. On top of the question of targeted areas of higher totals, QPF spread remains annoyingly large, with GEFS plumes indicating multiple converging solutions and a large degree of spread between these converging solutions. Therefore, totals are difficult to properly forecast with proper certainty. Still, it appears impacts from this system could be larger than our previous snow systems. Further complicating the forecast is a warm nose aloft that could shift the precip type, especially in our far southern counties. Despite this, general thinking is the primary precip type will be snow, although wintry mixes cannot be ruled out further south. At this time, primary impacts expected will be snowfall and visibility, causing travel problems. I'd start a thread for this one but I'm likely the only one here who will even benefit from this storm. 1 1 Quote Formerly *ahem*: LNK_Weather, TOL_Weather, FAR_Weather, MSP_Weather, IMoveALot_Weather.

Clinton Posted October 20, 2020 Report Share Posted October 20, 2020 NWS KC being cautious but still mentioning a chance of snow Sunday and Monday. .DAYS TWO THROUGH SEVEN...Wednesday through Monday A warm front will move through the area Wednesday developing showers and storms in the afternoon along and north of the Missouri River. No severe weather is expected, but some pockets of heavy rainfall may occur with overall rainfall totals from a quarter to half inch expected over northern Missouri. Thursday will warm up significantly on the backside of the warm front with highs in the 80s. Strong winds with gusts up to 40-45 mph possible. This warm up will not last long as a cold front will move through the area Thursday night, bringing a chance of showers and storms, some of which could be strong to severe. The main threat will be strong to damaging winds. Temperatures will drop rapidly with highs only in the 40s to 50s going into the weekend. Winter looks to arrive Sunday into Monday with some guidance indicating snow may be possible, but we will have to see how things trend.

CentralNebWeather Posted October 20, 2020 Report Share Posted October 20, 2020 NWS Hastings: Dry and chilly conditions Fri into Sat will give way to incr potential for wintry pcpn Sat night into Sun as a strong upper disturbance (near -2 std dev at H5 per latest EPS) digs into N Rockies and provides reinforcing shot of cold air. In fact, very impressive -20C H85 temp anomalies relative to 2000-2019 M-climate are poised to move in on Sun and brief inspection of forecast soundings show temp profiles more akin to winter months. The anomalous cold looks like a good bet, but details regarding potential for accum snw remains to be worked out. Nonetheless, decent run to run and model to model agreement (including ensembles) argues for incr confidence for at least minor snw accums for at least portions of the CWA this weekend. Stay tuned. 2 Quote Link to comment Share on other sites More sharing options...

Basically it was one solitary month between Thanksgiving and Christmas, then nothing. Similar atmospheric dynamics are at play currently and the fact that we find ourselves looking at your hurricane list is proof. 05-06 is also one of the (negative) analog winters for us and perhaps the finest example of how front-loaded Nina can end up very disappointing. You have to look at it at a different perspective. This is not something you see every year, but I would definitely get excited, if we end up breaking (not tieing, but breaking) the all time record tropical season. Now, in terms of how it affects our Winter, let it play day by day and hope for the best. 1 1 Quote Snowfall for Winter 2023 -24 for Metro Detroit Area Oct 2023: 0.2" AN Nov 2023: 2.2" AN Dec 2023: 0.5" BN Insane!

westMJim Posted October 20, 2020 Report Share Posted October 20, 2020 At this time Grand Rapids is on track of having its coldest October since 2008. In the past there has not been a clear path that a cold October leads to a cold or snowy winter. The fall color here NW of Grand Rapids is still very good to in places great. There are now some trees that have lost all of their leaves thought. At this time it is cloudy and 43 here at my house. 1 1 Quote Link to comment Share on other sites More sharing options...
Grizzcoat Posted October 20, 2020 Report Share Posted October 20, 2020 For those weather weenies- check this out. DSM high yday was according to ASOS- 37.4F. at 18:40 SEE here. But something is funny if you look at the 5 minute data either side of 18:40-- at 1835 and 1845-- see here-- This shows 33.8F to 37.4F to 33.8F in a span of 10 minutes. With snow on the ground , RH at 80% and Mostly Cloudy at 6:40pm in OCT?> i don't think so. The record cold high yday was 36F!!! I work with ASOS for DSM as a CWO- and this is being brought to the NWS attention, but they will likely dismiss it - even while saying it looks bad - because they like to roll with automation , even in error. Just thought I would share here and that ASOS's temp's are faulty more than you think. Heck not just the temp, but about every sensor that 1980's ASLOP"S technology has.

Tom Posted October 20, 2020 Author Report Share Posted October 20, 2020 I just got back from early voting and the line was quite long. Got there before they opened and waiting for about an hour till I got in. It was a bit chilly with a north wind and temp in low 40’s. I had my heavy jacket on for the first time this season.

Grizzcoat Posted October 20, 2020 Report Share Posted October 20, 2020 One thing not known by many is that ASOS temp sensor needs 3 consecutive minutes of a temp - or 3 outta of 4 for a temp to be recognized. For example. at 8:40 its 55F 8:41F its 55 8:42 it's 55F, 8:43 it's 56F 844 it's 56F and 8:45F it's 55F 8:46F 55F,,,- officially it never got to 56F. I've seen -20F in the winter for two minutes - but it went -19F for the 3rd minute and stayed at -19F. so -20F "officially" never happened. Also seen the same thing many times with 100F. just an. FYI... ASOS is not like a true max/min thermometer we used in the old days and still used by COOP observers in the chicken coop instrument shelters (dying breed) . 1 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.

james1976 Posted October 20, 2020 Report Share Posted October 20, 2020 Des Moines NWS seems pretty interested in the weekend setup: Strong surface cyclone will track south of Iowa but likely leave the state in a strong deformation zone, which could lead to a widespread rain/snow event. This will need to be monitored closely toward the end of this week to look for any kind of banding potential, and overall to see how the dynamics play out. For the start of the next work week, strong high pressure will settle in across the High Plains leaving the flow northerly, allowing very cold Polar air to dump into the region. This will likely result in some unseasonably cold temperatures during this timeframe. 2 1 Quote Link to comment Share on other sites More sharing options...
