Area Forecast Discussion National Weather Service Green Bay WI 543 PM CST Wed Feb 24 2021

Updated aviation portion for 00Z TAF issuance

SHORT TERM. Tonight and Thursday Issued at 246 PM CST Wed Feb 24 2021

The main concerns in the short-term forecast will be the potential for light snow/flurries late tonight into Thursday morning along with challenging low temperatures for tonight.

Tonight: The low pressure system that brought the rain and snow to the area Tuesday night will slide across the New England states this evening. High pressure will steadily build in from the Plains, creating fairly quiet conditions through much of the night. A weak shortwave is expected to brush through the northern portion of the area and touch off a few flurries or light snow showers, most concentrated along the WI/UP border overnight. Not expecting much, if any, accumulation from this system. Outside of any light precipitation overnight, expect cloud cover to increase from west to east.

Clouds are expected to clear across the area this evening, which will likely lead to an extended period of clearing through late this evening. In fact, timing the cloud cover arrival on satellite imagery, it looks like the clouds would arrive across central WI around midnight. This lends more support for the colder temperature trends across the area, especially across the areas that received fresh snow cover. After clouds begin to increase, temperatures will steady or slowly warm overnight. Overnight lows will likely drop into the single digits across the Northwoods and the low to mid teens elsewhere. Of course, if cloud cover arrives faster/slower, this will have an impact on temperatures.

Thursday: The surface ridge is expected to continue to shift east through the day Friday, which will bring fairly quiet weather to northeast Wisconsin. There may be a few lingering flurries in the morning; otherwise, expect clearing skies from late morning through early afternoon. High temperatures are expected to warm into the mid 30s for most locations.

LONG TERM. Thursday Night Through Wednesday Issued at 246 PM CST Wed Feb 24 2021

A few minor changes were made in the long term forecast, mainly revolving around precip potential on Sunday. Models continue to disagree on the potential for a colder day early next week.

Friday and Saturday . Dry and partly cloudy conditions are expected throughout Friday, and southwesterly winds will help boost temps into the middle 30s to lower 40s. Models continue to depict light snow moving across the area Friday night into Saturday morning as a quick moving clipper passes just north of the state. This coincides with a shortwave moving across the central or southern part of WI, exact placement varies by model. Overall forcing and moisture is a little less than yesterday's output, and as a result QPF/snowfall amounts are on the lighter side, with snow accumulations of 1 inch or less. Some rain or freezing drizzle at the start or end of event could also hinder snowfall totals. Roads may be slippery for a period Saturday morning, but with highs reaching the upper 30s and lower 40s Saturday road conditions should quickly improve.

Sunday . Have added a chance for light snow (mixed with a little rain) from 06Z to 18Z Sunday. Models continue to show an fgen band develop across the area during this time. The GFS is the strongest and most consistent in developing this band, however the ECMWF is also now showing some hints. Added chance PoPs for now, but confidence is still somewhat low. Will need to see how this trends over the next couple days.

Monday through Wednesday . Continuing to monitor the temperature trends early next week. The 12Z GFS is not as aggressive with the cold pocket of air reaching WI. For Monday, MEX guidance has come up to a high in GRB of 24 while the ECX has 36. This is an improvement from the 20 degree spread from the 00Z guidance. Continue to stick with a blended model solution for temperatures early next week, which would yield highs in the 20s on Monday. This is below normal, but not nearly as cold as a couple weeks ago. Temperatures bounce up to at or above normal level through at least midweek. Overall weather looks quiet as well, with high pressure early in the week and weather systems remaining either north or south of the state after that.

AVIATION. for 00Z TAF Issuance Issued at 536 PM CST Wed Feb 24 2021

Skies have cleared over the region, but satellite showed clouds quickly approaching from northern MN. Expect these to reach north central WI around midnight, but they may thin out a bit before they arrive in eastern WI late tonight. Although ceilings should start out around 6-7K FT, they are expected to lower to MVFR in parts of north central and central WI late tonight into early Thursday. Have also added a mention of flurries for the western TAF sites late tonight into Thursday morning, with a TEMPO group for snow showers at RHI. Expect clearing to occur late Thursday morning and early afternoon. Gusty west winds will also develop Thursday morning.

GRB WATCHES/WARNINGS/ADVISORIES. NONE.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
