Short term (this evening through Monday)
issued at 306 pm cst Sun dec 9 2018
the short term period remains quiet with the main concern stratus
and fog development tonight.
Stratus remained along the international border and arrowhead this
afternoon but was diminishing. The clouds in the arrowhead will
likely hang on the longest into this evening. There remains some
uncertainty if stratus will redevelop tonight and the rap indicates
northwest wisconsin will have the best chance along with some fog. A
shortwave will move into northwest minnesota late tonight then
through the region on Monday. Soundings continue to be very dry so
we expect little from this shortwave. We do increase cloud cover
overnight but only to partly cloudy for most areas with a bit more
cloud over northwest wisconsin. Lows will dip to 5 to 15 for much of
Any stratus fog that forms tonight will lift through the day Monday
and highs will rebound into the mid twenties to around thirty.
Long term (Monday night through Sunday)
issued at 306 pm cst Sun dec 9 2018
mild temperatures are expected for the long term with highs
trending above average. There is a chance of light snow Wednesday
in northwest wisconsin and no significant systems are forecast.
A progressive pattern aloft is forecast for the upcoming week
with the subtropical jet well to our south across the southern
conus. A weak shortwave trough will move through the region
Wednesday which may provide sufficient lift for a few snow
showers over northwest wisconsin. With limited moisture
available, think a dusting of snow up to maybe a half-inch is
forecast. Another shortwave trough will cruise eastward through
the region from early Thursday morning through the afternoon.
Another round of light snow showers with the trough. High|
pressure then returns Friday and Saturday. Southwest flow aloft
may result in temperatures warmer than the consensus blend for
Saturday. The deterministic ECMWF and gem forecasts point to
temperatures much above normal for the start of the weekend. Have
remained close to the consensus blend for now with the GFS not
quite as warm.
Aviation (for the 06z tafs through 06z Monday night)
issued at 1144 pm cst Sun dec 9 2018
high pressure will keepVFR ceilings in place through most of the
period. Some MVFR ifr visibilities will be seen this morning at
hib, brd and hyr with some light fog. Smoke haze is again expected
throughout the region on Monday, but visibilities are expected to
remainVFR. A brief period of MVFR ceilings will be possible
around sunrise at hyr due to some low stratus, but it is expected
to scatter out by mid-morning if it does occur.
Issued at 1002 pm cst Sun dec 9 2018
stronger winds aloft may mix down along the bayfield peninsula, so
opted to raise a small craft for this and the resultant waves that
occur. This is accompanying a broad weak low that is crossing the
northern side of lake superior through Monday evening.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
