MKEstorm Posted January 6 Report Share Posted January 6 MKX in their afternoon discussion mentions that models have shifted northwest a "tad". Also mentioned that the system is now coming onshore and should be better sampled. https://forecast.weather.gov/product.php?site=MKX&issuedby=MKX&product=AFD&format=CI&version=1&glossary=1 Monday through Saturday: There remains concern for a strong system to bring widespread accumulating snowfall to southern Wisconsin early next week. Latest deterministic model solutions have shifted northwest a tad more, putting the forecast area more into the heart of the higher snowfall totals. Ensemble solutions suggest a high chance (70-90%) of measurable snowfall with this system, with the chance for 3 inches or more increasing to 50-80 percent across much of southern Wisconsin. The higher snowfall probs remain across the southeast half of the forecast area. While confidence is gradually increasing in impactful snowfall, it is worth noting that there is still a sizable spread among ensemble members with the track/timing/intensity of the low. Now that the system is coming onshore across the western United States, it will be interesting to watch model trends over the next day or so with the system better sampled over land. Monday still looks dry through late afternoon as high pressure exits ahead of the approaching low. Given current model solutions, snow would then spread in from the southwest per warm air advection and frontogenesis ahead of the low. Light snow accums (1-2 inches) would be possible by daybreak Tuesday. The better forcing/moisture is currently expected to arrive by mid- afternoon Tuesday, continuing into the evening. The bulk of snow accumulations would fall during this period. Snow would then gradually wind down west to east overnight. Lake Michigan is still on the mild side, with the latest south lake water temp reading this afternoon sitting at 43 F. Given the early week system isn`t very cold, these mild lake temps could result in some rain/snow mix for lakeshore areas, though model soundings still point to mainly snow. The lake could also provide some enhancement of snowfall amounts in the east, given sfc to 850 mb temp diffs around 10C. Again, these finer details of timing and amounts will ultimately depend on the exact low track. For now though, this is the way things are trending. 2 Quote Link to comment Share on other sites More sharing options...

Clinton Posted January 6 Report Share Posted January 6 EAX lengthy AFD AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 241 PM CST Sat Jan 6 2024 .Discussion... Issued at 227 PM CST SAT JAN 6 2024 Key Messages: - Winter storm impacts the area Monday and Tuesday. Right now, exact amounts remain uncertain, but confidence is growing that some portions of the area may see 5 inches or more. -Bitterly cold temperatures expected for the second half of next week into next weekend -Additional snowfall may be possible late next week Discussion: Saturday-Sunday: Quiet weather expected today and Sunday ahead of the more significant wave arriving Monday. Cloudy skies and patchy drizzle and flurries are expected to persist through the day with highs mainly in the mid to upper 30s. On Sunday expect dry weather to remain with high in the mid 30s to mid 40s and the brief return of some sunshine to the area. Monday Tuesday: Moderate uncertainty continues with the expected storm system on Monday and Tuesday. A deepening trough moves off the Rockies Monday morning and forms a closed low. It is expected to track east through the southern Plains on Monday into Tuesday bringing impacts to our forecast area. As stated previously, uncertainty remains with this system due to slight differences in track of the low and warm temperatures ahead of its arrival. Models are in decent agreement that the warm air advection into the area will allow precipitation to begin as mostly rainfall or a rain/snow mix Monday morning. Northern parts of the forecast area may favor a mixed precip type initially, but wet-bulbing effects may allow for a transition to all snow by the afternoon. The rest of the area may take a bit longer to transition to snow, as they await the approaching low drawing in colder air. Snowfall is expected to continue through much of the area Monday night into Tuesday morning as the low tracks south of the forecast area. It`s still tough to talk about specific amounts due to uncertainty in the exact track of the system and timing of the cooling temperatures profile, but it`s looking more likely that somewhere in our forecast area will see impactful snowfall amounts. Depending on track, there is also potential for a very sharp gradient in snowfall accumulations, noted well by the NAM`s slightly farther north track. There is still some differences even in model blends/ensemble, but it seems that they are better communicating the potential for some higher amounts in our forecast area. Starting on the lower end, NBM probabilities show a greater than 75% chance of 1 inch of snow for the entire area. LREF has a greater than 95% chance. The NBM probability of 3 inches is 50-70% for the northern half of the CWA and 40-50% to the south. The LREF on the other hand has a >80% chance of 3 inches in the north and a 70-80% chance in the south. Looking at potential for amounts over 5 inches is 40-60% north of US-36 and 30-40% for points south according the the NBM. The LREF on the other hand, keeps a 70-80% chance of 5 inches for the counties on either side of US-36. Locations further south have a 60-70% chance of seeing 5 inches according to LREF, which is quite a bit higher than NBM probabilities for the same amount. Amounts of 8 inches or greater are 30-50% near US-36, and 30-40% according to the NBM. Lower probabilities from the NBM may be in part to a slightly warmer bias compared to other models, due to our recent above normal temperatures. All of this to say that despite model differences, there is starting to be some consensus that at least a portion of our forecast area has potential of reaching winter storm criteria (5+ inches). Snowfall uncertainty is shown well by the extremely broad range in both the NBM and LFEF`s 25th to 75th percentiles ranging from 1 to 9 inches for a lot of the forecast area. Again, actual forecast amounts are still going to be very difficult to nail down, especially because of significant impacts from minor temperatures differences, and the potential for slightly warmer temperatures to cut into snowfall amounts. Outside of snowfall, gusty winds are expected Tuesday as the low passes to the east and the pressure gradient tightens. Northerly gusts of 35-45 mph will be possible leading to potential for visibility restrictions even after snowfall ends. Highest wind speeds occur after snowfall moves out of the area, but there still remains potential for a brief period of white out conditions Tuesday afternoon and evening. Additionally, wind chill values on Tuesday will remain in the teens, falling into the single digits after sunset. Winds gusts should subside overnights as the low continues to push east of the area. Forecast confidence will likely improve later tonight and Sunday as the wave finally makes its way on shore and we can better sample the system. Regardless, with potential impacts to the forecast area Monday night and Tuesday morning, it will be important to stay tuned to the forecast this weekend. A winter storm watch has been issued for the entire forecast area for Monday and Tuesday. Upgrades to warnings and advisories can be expected as confidence improves. Rest of the week: After Tuesday, it looks like we will remain in an active pattern through the week into next weekend. Several additional waves looks to move through the forecast area. Colder air remains in place through the week so additional winter weather will be possible. Temperatures will be significantly colder starting Thursday and continuing into next weekend. Highs in the 20s and teens and lows in the single digits or even below zero look possible. Another impressive wave looks to swing into the region Friday into Saturday bringing another round of potentially significant snowfall for somewhere in the region. While this is still way too far out to get into any specifics, with cold air already in place, heavy snowfall is looking possible for somewhere in the region. There is still a lot of run to run model variability to know if we will see any impacts from this system or not. 4 Quote Link to comment Share on other sites More sharing options...

KTPmidMO Posted January 6 Report Share Posted January 6 I'm about to throw the towel in on this one. I went from being in 15" yesterday and a lot of models agreeing that the main snow band would be through central mo. Now, the only 2 models showing worth anything here in central MO is the GDPS and GFS. And the GFS has went from giving me 15" to now barely even 5." Another run or 2 and I'm bound to completely be out of it. Just a little disheartening after being in the bullseye almost all week. 1 1 Quote Link to comment Share on other sites More sharing options...
