SHORT TERM. (Today and tonight) Issued at 345 AM CST Wed Nov 25 2020

Forecast concerns in the short term will dense fog, improvement this morning, extent of re-development tonight, and how far north any precipitation makes it later today.

Last night, we were watching the strong moisture advection, frontogenesis, and ascent with the lead shortwave trough with the approaching storm system. Precipitation started out as snow with even a few lightning strikes across the southern part of the forecast area. The snow continued to lift north during the day Tuesday. An arc of rain and snow continued from northeast Nebraska into northern Iowa, southern Minnesota into central and southern Wisconsin. Another shortwave moved through enhancing precipitation in the band during the afternoon before generally weakening by 6pm. Temperatures were key and many valley areas with warmer temperatures experienced much of the snow melting as it fell, even though it snowed for several hours with large wet flakes. Farther south, the snow changed to rain. For much of the day Rochester was 32/33 degrees and La Crosse 34/35. The southern part of the forecast area made it into the upper 30s. Rochester, MN ended up with 4 inches of snow, breaking their daily record of 2.2 inches set in 1996. The La Crosse airport had 1 inch and here at the La Crosse NWS 3.8 inches.

The MPX 00Z sounding was saturated in the lowest 6k ft. Water vapor satellite imagery, heights and lightning strikes highlight the closed low over Kansas with thunderstorms extending from parts of Missouri into Arkansas and Texas. The northern stream 500mb trough stretched from northern WI across south central MN into southeast South Dakota. The surface map had surface low pressure centered around Emporia, KS with a front from St. Joseph, MO to Cedar Rapids, IA to Rockford, IL. Locally, temperatures had not changed from the daytime readings and were holding steady. Due to the snowfall, rainfall, warm temperatures and high dewpoints, fog with areas of dense fog were common across the region. Per obs and a look at the nighttime RGB satellite imagery, clearing did not start until the central Dakotas.

A dense fog advisory covers parts of the area until around 15Z. As the winds aloft and surface winds have been increasing, the dense fog has improved west of the river with many locations 2 mi or greater With the melting snow and variable winds. may see some of the vsbys bouncing around in southeast MN/northeast IA . but should continue to see improvement this morning.

Through the day, the storm system over Missouri will skirt the forecast area to the south. A few showers could clip our far southern counties, so left some pops in there. Little temperature change today with highs in the upper 30s to lower 40s. There is not a lot of cold air with this system, so once the low track to our southeast, the colder air edges southward. The surface flow is weak and although we lose our deeper moisture, the RAP is more pessimistic on losing the low clouds with fog redeveloping.

LONG TERM. (Thursday through Tuesday) Issued at 345 AM CST Wed Nov 25 2020

The clearing should be moving into the west Thanksgiving morning. With the decrease in clouds, we have highs in the 40s for most locations. A weak front brings a wind shift through later Thursday with some reinforcing cooler air Friday. Both of these frontal passages are dry. Highs Friday should slip back into the 30s with a few readings in the lower 40s. Southwest winds and quiet for Saturday with above normal highs 45 to 50. For Sunday into Monday we are monitoring where the energy will be focused with a mid- level trough developing over the region. The EC keeps the storm system split with a dry forecast locally, however the GFS tries to phase the storm system with accumulating snow. Our current forecast has trended toward the EC. There is a large spread in the solutions, however there is consensus on stronger winds on the back side of the system with colder temperatures for the start of the work week. The global models seem to come together better with a significant system for parts of the Great Lakes into the Ohio River Valley.

AVIATION. (For the 06Z TAFS through 06Z Wednesday night) Issued at 1058 PM CST Tue Nov 24 2020

IFR conditions are expected to prevail for most if not all of the forecast period through Wednesday evening. The fog will remain until the middle of the morning with LIFR to IFR reductions. It is expected to lift as some slightly drier air aloft starts to mix in underneath the inversion. This drier air does not look to be enough to break up the ceilings however, with these remaining at or below 1000 feet for the most part.

ARX WATCHES/WARNINGS/ADVISORIES. WI . Dense Fog Advisory until 10 AM CST this morning for WIZ017-029- 032>034-041>044-053>055-061.

MN . Dense Fog Advisory until 10 AM CST this morning for MNZ088-096.

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.
