NWS Green Bay, WI wrote its last area forecast discussion before the first event at Feb 6, 1:29 PM CST, 31 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Green Bay WI 129 PM CST Thu Feb 6 2025 Forecast discussion for routine afternoon forecast issuance .KEY MESSAGES... - Gusty west winds of 25 to 35 mph with gusts of 40 to 50 mph are expected to continue into this evening. An isolated gust over 50 mph is possible. The gusty winds may create minor blowing and drifting snow and cause difficult travel for high-profile vehicles, especially on north-south oriented roads. The strong winds may also cause some damage to trees and power lines, resulting in sporadic power outages. - Hazardous winter travel is expected late Friday night through Saturday night due to a widespread accumulating snowfall. There is a 30-50% chance of snowfall accumulations greater than 6 inches over central to east-central Wisconsin where a Winter Storm Watch has been issued. - Bitterly cold wind chills from 15 below to 20 below will be possible on Monday and Tuesday nights over central and north- central Wisconsin. && .DISCUSSION... Issued at 129 PM CST Thu Feb 6 2025 Short Term...Tonight and Friday Strong westerly winds remain the primary focus of the short-term forecast. Winds are expected to peak this afternoon as low-level lapse rates continue to steepen and the strongest push of CAA arrives. Gusts are expected to reaching 45-50 mph across much of the region. If mixing heights can reach about 2500ft a few isolated gusts over 50 mph may be possible. Winds will slowly star to diminish after sunset, however, breezy conditions will remain into the early overnight hours. As the jet streak moves off to the east winds should then become much weaker by Friday morning. Webcams have shown some minor blowing snow and expect that to continue through sunset, however, impacts seem minimal due to the shallow snowpack. High profiles vehicles may also be impact by the strong winds, mainly on north-south oriented roads. Light snow showers also remain possible across far north-central WI through this evening as the axis of a mid-level short moves moves across Lake Superior. Don't expect this snowfall to amount to anything more than a tenth or two. Behind this trough colder air will start to filter in over northern WI with lows tonight falling into the single digits below zero near the UP border. Areas along the lakeshore and in the Fox Valley will see lows near 10 degrees. Surface high pressure pushing into the region Friday will bring period of quiet weather before the next round of accumulation snow arrives this weekend. Long Term...Friday Night Through Thursday Focus of this forecast continues to revolve around snowfall potential on Saturday, followed by low wind chills next week. Weekend Snow Potential: A low amplitude, positively tilted shortwave remains forecast to track from west to east across the forecast area from late Saturday morning through early Saturday evening. Moderate mid-level warm advection and frontogenesis will precede the shortwave starting very late Friday night when light snow is expected to develop over central WI before spreading over to the rest of northeast WI on Saturday morning. The strongest forcing will likely arrive just ahead of the shortwave from late morning through mid-afternoon Saturday when integrated omega peaks in the dendritic growth zone. The forcing trails off as the shortwave exits to the east by Saturday evening. In terms of moisture, precipitable water anomalies peak about 160-170% of normal around midday Saturday, but doesn't appear to be anomalously high as deeper moisture remains confined well south of the region over the mid-Mississippi Valley. Do not see much in the way of elevated instability or high mid- level lapse rates that could lead to higher end snow values. Do not think there will be much in the way of lake enhancement as 1000-850mb flow is relatively weak and around 10 kts or less out of the northeast. Perhaps right near the Lake Michigan shoreline very minor lake enhancement is possible. The most favorable aspect of this system will be the dendritic growth profile where moderate to perhaps strong lift will occur at times within the dendritic growth zone. This is most pronounced over central to east-central WI where the temperature profile is warmer. As a result, this should lead to efficient snowfall production, particularly during periods of the strongest lift from late morning through mid-afternoon. The dendritic growth zone depth is much smaller (colder thermal profiles) over far northern WI which is not as favorable. In terms of trends, ensemble qpf has trended downward over the past 24 hours of model runs, particularly over far northern WI. As a result, trended qpf downward by about 20% which dropped snowfall amounts in the Winter Storm Watch area by 1-2 inches. No changes to the Winter Storm Watch appear warranted as confidence to issue a warning just isn't there yet (and may not get there). Still anticipate some changes to snowfall amounts over the next 24 hours. Temperatures...Will be trending downward next week with highs in the single digits to teens. Wind chills are forecast to fall into the 10 below to 20 below range every night from Monday night thru Wednesday night, particularly over central and north-central WI. && .AVIATION...for 18Z TAF Issuance Issued at 1124 AM CST Thu Feb 6 2025 Skies will continue to clear out across far eastern WI early WI as they did across central and northern WI this morning. Westerly winds have begun to strengthen with gusts already reaching 25-35kt across the region. Winds will continue to increase and peak with afternoon with sustained winds between 15-25kts and peak wind gusts reaching 35- 40kts. Winds will continue to be breezy through the evening before starting to diminish overnight into Friday morning. MVFR cigs will return later this afternoon to northern WI along with a few light snow showers while skies south of a AUW to GRB line should remain clear the remaindered of the day. Scattered mid and low level clouds will start to filter back into central and east central WI Friday morning ahead of the next system forecast to bring a round of accumulation snow to the region Saturday. && .GRB WATCHES/WARNINGS/ADVISORIES...
