Today and tonight... Forecast confidence medium.
The upper trough over the northern plains continues to drop south
across lake superior and wisconsin tonight, with southern
wisconsin getting into the entrance region of the 115 knot 250 mb
jet later tonight. Moderate upper divergence through sunrise
today, then weak upper divergence.
A mid level 500 mb shortwave moves across southern wisconsin late
this afternoon and evening. Only weak 700 mb upward motion due to
the cold advection. However lapse rates steepen, and zero to 1 km
mixed layer CAPE values increase to around 350 joules kg.
Therefore expect at least isolated showers late this afternoon
Cold air advection will be occurring today behind the cold front.
Some initial clearing, but then more convective clouds will
develop this afternoon and into the evening with the steepening
Saturday through Monday Forecast confidence is medium.
An upper trough will dominate with a strong shortwave moving
through Saturday afternoon. Models are in agreement showing some
precip and a few hundred j of cape. Temperatures will be cooler
with the influence of the trough. At the surface, low pressure
will remain over southeast canada with high pressure sliding
south across the norther plains. Low level lapse rates will be
steep so we may tap 850 winds of 20-25 knots. West winds will be
a little gusty on Saturday.
Another shortwave moves through on Sunday creating another chance
for mainly afternoon showers and thunderstorms. There is less|
instability on Monday. The ECMWF shows almost no CAPE so just have
chance for showers.
Tuesday and Wednesday Forecast confidence is high.
A mid level ridge pushes into the region on Tuesday and
temperatures start to rebound. Surface slides southwest of the
state on Tuesday bringing dry weather. Then the high moves off to
the southeast as the next low approaches the region. Surface flow
becomes southwest and moisture advection increases. Instability
builds and expect showers and thunderstorms Wednesday or Thursday
as the low moves through.
A line of thunderstorms will slowly slide southeast through
southern wi overnight. This line is moving slower than expected.
Scattered storms are possible out ahead of this line. The risk for
severe storms is pretty low for the rest of the night.
Period of MVFR ceilings possible behind the front overnight.
Quiet weather expected Friday.
Thunderstorms are sliding southeastward across the area early this
morning. A period of north winds of 15 to 25 mph with the front.
Then mainly northwest winds later today. Some gusts to 25 knots,
especially north areas this afternoon. As a result have issued a
small craft advisory there for this afternoon and early evening.
Mkx watches warnings advisories
Lm... Small craft advisory from 1 pm this afternoon to 8 pm cdt this
evening for lmz643.
Today tonight and aviation marine... Hentz
Saturday through Thursday... Marquardt

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.
