Area Forecast Discussion National Weather Service La Crosse WI 658 AM CDT Wed Apr 8 2020
SHORT TERM. (Today through Tonight) Issued at 249 AM CDT Wed Apr 8 2020
Area caught up in stagnant/baggy airflow as a cold front was hung up from northeast MN through south central MN, into eastern NE. In the meantime, temperatures have cooled down to the dewpoint and as a result, widespread fog has set up -mainly east of the Mississippi River. This is expected to last until around 9 am before dissipating as a slightly drier push of air moves in from the west as the cold front pushes through. As such, a dense fog advisory is in effect until 9 am this morning for portions of northeast IA/southeast MN, and much of southwest into central WI.
As the cold front moves through this morning, it will be reinforced by a fairly vigorous mid-level wave moving through the Northern Plains. Steepening lapse rates, favored right entrance region of 300mb jet, and increasing pv-advection with the mid-level wave will lead to showers and possibly a few thunderstorms this morning into this afternoon. Otherwise, breezy northwest winds kick in today, ushering in cooler/drier (compared to yesterday) airmass. Plan on highs in the lower 50s to lower 60s.
High pressure builds in tonight for clearing and chilly conditions. Look for lows bottoming out in the 20s and lower 30s.
LONG TERM. (Thursday through Tuesday) Issued at 249 AM CDT Wed Apr 8 2020
A secondary mid-level trough and surface cold front drops into the area Thursday. This will likely bring in extensive cumulus field along with isolated shower activity. Otherwise, a rather raw day on tap with highs only in the upper 30s to middle 40s. Fairly breezy northwest winds will only add to the chill.
Cold high pressure builds into the region Thursday night into Friday. Despite full sunshine Friday, highs will struggle into the 40s for highs.
Deepening longwave trough carves out over the central CONUS through the rest of the period with an embedded shortwave trough rotating through Saturday for a chance of rain. Latest ECMWF/GFS model run then shows deeper surface low ejecting northeast out of the southern Plains up toward the Great Lakes region Sunday into Monday. Will have to watch this system closely as there may be enough cold air available for some cold rain turning into snowfall. Otherwise, looking raw/chilly with highs Sunday in the 40s and in the 30s/40s Monday.
AVIATION. (For the 12Z TAFS through 12Z Thursday morning) Issued at 652 AM CDT Wed Apr 8 2020
LIFR fog will quickly burn off within the next few hours at LSE. Otherwise showers and perhaps a few rumbles of thunder will be the story for today as a strong impulse works through the region. Already have had a few rumbles of thunder south of RST this morning. Expect the showers upstream over southern MN and northern IA to fill in over the next few hours as forcing strengthens along a cold front dropping through the area. That will bring the greatest chance of showers from late morning into the afternoon before the line slides off to the east by late afternoon. Could see MVFR visibilities within the heavier showers, also a small chance for briefly touching MVFR ceilings. Otherwise back to solidly VFR by this evening. Winds turning NW behind the front today will become gusty this afternoon, remaining somewhat breezy into tonight.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
