forecast discussion for routine afternoon forecast issuance

Short term Tonight and Wednesday
issued at 329 pm cdt Tue mar 19 2019
a mid level short wave and surface cold front approaching from the
northwest will bring an increase in clouds this evening. Snow can
be expected across northern wisconsin late tonight as the front
moves into upper michigan. Precipitation will continue to spread
across the area Wednesday morning, but snow should become mixed
with rain and then change to all rain as temperatures warm up
during the day. Rain is expected to make its way out of most of
the forecast area Wednesday afternoon.

Liquid equivalent of precipitation should be no more than 0.1
inch with snow accumulations in the north of around half an inch
at most. Lows are only expected to fall into the upper 20s to
lower 30s as clouds and dew points increase tonight. Stuck close
to guidance and both the 12z NAM and GFS mos had high temperatures
reaching the 40s on Wednesday.

Long term Wednesday night through Tuesday
issued at 329 pm cdt Tue mar 19 2019
a few lingering showers are possible Wednesday evening in far
north central and northeast wi, in the wake of a cold frontal
passage. Another fairly vigorous short-wave is expected to
brush far northeast wi Thursday afternoon, but produce little in
the way of precipitation. A fairly strong cold frontal passage
will accompany this system, so have bumped up winds a bit. Looks
like a solid small craft advisory or possibly a low-end gale
warning on lake michigan Thursday night into Friday.

High pressure will dominate our weather from Friday through
Saturday night. After a brief drop off in temperatures on Friday,
a modest warm-up is anticipated over the weekend, with highs
reaching the 40s and lower 50s.

The GFS continues to struggle with precipitation chances late in
the weekend, and now produces moderate precipitation with a
frontal system on Sunday, with lingering light QPF across c ec
wi Sunday evening. The ECMWF is much drier, with just increasing
clouds on Sunday and light precipitation over c ec wi Sunday
evening. Once again, would lean toward the drier ecmwf, given its
better consistency. Cooler temperatures will return early next
week, as canadian high pressure settles over the region.

The expected warm-up will be tempered a bit by the frontal
passages on Thursday and Sunday, but daytime temperatures should
still get above freezing each day (then drop below freezing at
night). So, despite a lack of significant rainfall, a gradual snow
melt and possible ice jams may still result in additional
flooding, especially toward next weekend. Hydrologic statements
were issued earlier today to highlight the continued flooding
concerns.

Aviation For 18z TAF issuance
issued at 134 pm cdt Tue mar 19 2019
vfr conditions will give way to mainly MVFR ceilings and or
visibilities as showers move into the area from the north. Would
not expect any snow in northern wisconsin until midnight or a
little later. The snow and MVFR conditions will spread across the
rest of the area overnight and during the day on Wednesday but
snow should mix with, and then change to, rain as temperatures
warm during the day. A few ifr ceilings are possible in heavier
precipitation.

Hydrology
Issued at 329 pm cdt Tue mar 19 2019
flood warnings remain in effect for a few rivers in east-central
wisconsin. Rain amounts in the coming days are expected to be
fairly light, with overnight lows being cold enough to stop
melting during the night. The flooding is not expected to be
exacerbated by any of the light precipitation during the upcoming
week.

Grb watches warnings advisories
None.

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.
