Area forecast discussion, Jan 10, 11:49 AM CST, 3 hours 27 minutes before
Area Forecast Discussion National Weather Service Green Bay WI 1149 AM CST Fri Jan 10 2020 Updated aviation portion for 18Z TAF issuance .SHORT TERM...Today...Tonight...and Saturday Issued at 402 AM CST Fri Jan 10 2020 The main concerns for the short-term portion of the forecast will be the potential for light snow and blowing snow tonight into early Saturday morning. Heavier snow and blowing snow may develop yet again late Saturday afternoon, but confidence in the final low trek is lower with this update. Today: As a broad low pressure system meanders across eastern Ontario and western Quebec, another low pressure system is expected to develop across the Panhandle of Texas. Ahead of the low, a fairly strong south to southwest LLJ is forecast to develop across much of the the lower and mid-Mississippi Valley. This will effectively help to rapidly transport moisture northward, toward southern Wisconsin. As this happens, the Plains surface low is expected to lift northeastward as it elongates along the aforementioned, nearly stationary, frontal boundary. This would lead to steadily increasing/thickening cloud cover across central into east-central WI. Models aren't really painting out much QPF across the area through much of the day. Most of it remains south of the front. Otherwise, high temperatures are expected to range from the low to mid 20s over central/north-central WI to the mid 30s elsewhere. Tonight: The aforementioned surface low is expected to lift northeastward along the front, into lower to mid-Mississippi Valley. At the same time, a surface ridge is expected to build across the northern Plains. Convergent flow between these features along with fairly strong 850-700 mb FGEN banding, to the northwest of a stationary surface front, is expected to pass through the east- central and far northeast portions of Wisconsin. Additional support will be provided by a strong upper-level jet positioned to the north of the area. This places much of northern WI in the favorable right- entrance region of the jet, which is indicative of upward vertical motion and rapid evacuation of mass through the column. The combination of these features along with fairly deep moisture lifting northward into the area, will lead to a band of light to moderate snow across portions of east-central and far northeast WI. Generally looking at 1 to 3 inches of snow in those areas, heaviest from the Door Peninsula through much of the Fox Valley. To the northwest of those locations, accumulations are expected to be significantly lighter, as they remain closer to the influence of the drier surface ridge and are farther away from the FGEN banding. The pressure gradient will begin to increase across the area overnight, which may lead to some blowing and drifting snow, especially for unsheltered locations and locations close to Lake Michigan. Overnight lows are expected to range from the single digits above zero north-central to the teens elsewhere. Saturday: The intensifying low pressure system is expected to lift northward along the nearly stationary frontal boundary through Saturday afternoon. There may be some lingering snow showers close to the front, over the Fox Valley during the morning hours, but the better chance of heavier snow will develop toward the late afternoon hours. This will be as the surface low lifts northward through the mid-Mississippi Valley. At the same time, a vort max is expected to round the base of the upper-level trough as it lifts toward northern Illinois. Moisture will steadily increase/deepen into the late afternoon hours, allowing for moderate snowfall to lift into east- central portions of Wisconsin. Winds will also become gusty as the pressure gradient tightens across the area. There are some model differences with the final storm trek, with the EC/Canadian/GFS taking the low farther east than previous runs, which would reduce the totals across the CWA. The NAM remains farther west, brining a much heavier swath of snow across the east-central portions of Wisconsin. The farther east movement in the low center, reduces the confidence a bit in the highest snowfall totals, but it doesn't reduce it enough to change the current Winter Storm Watch that is in effect. Even if the snow totals are a bit lower, the combination of falling snow and blowing snow would lead to some impacts, including lower visibilities and the potential for some lake shore flooding and ice shoves. At this point, will continue the Winter Storm Watch and see if later models come into better agreement with the afternoon update. .LONG TERM...Saturday Night Through Thursday Issued at 402 AM CST Fri Jan 10 2020 Active weather pattern continues in the extended forecast as southwest flow brings several rounds of snow across the forecast area. Main focus is on the system early Sunday, as there is still much uncertainty. From 00Z-12Z Sunday, a surface low is generally expected to track across the southern Great Lake/Ohio Valley area, but where this system will track remains uncertain. The latest (00Z) ECMWF took a jog to the east (after a few runs trending W), the GFS is still trending east, and the Canadian is now so far east much of the forecast area is dry, especially west of the Fox River. The NAM is similar to the GFS/EC solutions. Therefore, sticking with a blend close to the GFS/EC which features high PoPs across the Fox Valley and east- central WI, and chance PoPs once getting into north- central Wisconsin. However, QPF for this wave of precip (which would begin a couple hours before 00Z) is lower than the previous forecast, ranging from about 0.10 inches in the north to 0.40 inches along the lakeshore. As a result, snowfall totals are lower than the previous forecast, ranging from 1 to 3 inches in north- central Wisconsin to 6 to 7 inches in east- central Wisconsin. Amounts may be a little high near the lake shore where some lake enhancement is possible. Overall, confidence in these amounts is low. The other element to keep in mind during this time is the wind speeds. Northeast winds will be gusting to around 30 to 40, which would easily creating blowing and drifting snow, especially across the Fox Valley and east- central WI. Additionally, the strong NE winds could create ice shoves or lakeshore flood. See the Hazardous Weather Outlook (HWO) for additional info. With all that said, models do agree this system will pull far enough east Sunday morning and snow will come to an end. Expect dry conditions through the rest of the morning and afternoon, and then another shortwave approaches from the southwest. This would bring another shot of snow Sunday night. Snow amounts look lighter with this quick moving system. For the rest of the week, expect active weather with several waves to move up from the southwest. Right now, Tuesday and Thursday appear to be the target days, but with so much waffling in the models confidence is low. Stuck with a blended model forecast. Temperatures will be near or a little above normal through at least Tuesday or Wednesday. There are some indications of cooler temps for the second half of the week, but models disagree on this as well. && .AVIATION...for 18Z TAF Issuance Issued at 1143 AM CST Fri Jan 10 2020 Patches of MVFR stratus were eroding across the region at midday, and high clouds were increasing ahead of the next system. This system will bring a brief period of light snow to the eastern TAF sites starting late this evening, and continuing into the overnight hours. Will likely see VSBYs in the IFR category. Strong winds will affect the Fox Valley and lakeshore areas tonight into Saturday, with NNE wind gusting to around 30 kts. Farther west, surface winds will not be as strong, but increasing winds aloft may bring a period of LLWS Saturday morning. && .GRB WATCHES/WARNINGS/ADVISORIES...

Snowfall accumulations are expected to be in the 1 to 3 inch range, which will likely lead to snow covered and slippery roads. Some blowing snow may cause reduced visibilities overnight. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Another round of snow is likely late Saturday afternoon through early Sunday morning, however there is still uncertainty on the storm track and snowfall amounts. This storm will have the potential to produce snow amounts of 6 inches or more along with blowing snow, especially across east-central Wisconsin. In addition, gusty northeast to north winds will increase the potential for ice shoves, lakeshore and bayshore flooding, and shoreline erosion. Additional chances for light accumulating snow will occur at times from Sunday night into the middle of next week. .SPOTTER INFORMATION STATEMENT...
