forecast discussion for routine afternoon forecast issuance

Short term Tonight and Thursday
issued at 254 pm cdt Wed mar 29 2017
mostly cloudy skies prevailed across the region this afternoon.

Temperatures ranged from the upper 30s near the lake michigan
shoreline to the upper 40s across the far north where the cloud
cover was not as thick.

Main concern for tonight will be snowfall totals across portions
of central and east-central wisconsin. Many complicating factors
to deal with including drier air advecting in from the east,
boundary and ground temperatures, and precipitation intensity and
qpf amounts. The 12z ECMWF has backed off on the heavier qpf
amounts across the fox valley and lakeshore region. Surface and
road temperatures should be a few degrees above freezing
overnight. With road and air temperatures slightly above freezing,
will need more intense precipitation to get snow to accumulate. At
this time, think an inch or two of snow is possible from wisconsin
rapids east to appleton to kewaunee, with lower totals to the
north and south. If a strong east-west band of precipitation can
set up for a period of time over the same area, locally higher
snowfall amounts are possible in this region. Also, the far north
is expected to get little or no precipitation with this system.

A mix of rain/snow should change over to mainly rain by late
morning on Thursday as temperatures warm into the upper 30s to
lower 40s. The warmest readings will be across the far north.

Long term Thursday night through Wednesday
issued at 254 pm cdt Wed mar 29 2017
precipitation type Thursday night, a generally dry weekend and the
track and precipitation trends with two significant low pressure
systems next week, are the main forecast highlights.

Low pressure tracking into the great lakes will continue to bring
gusty northeast winds and precipitation to most of the forecast
area Thursday night. Rh timesections show a lack of mid-level
moisture and ice crystals through the night, so precipitation
type should be mainly rain or freezing rain, depending on surface
temperatures. Have kept temperatures a little above freezing in
the fox valley and lakeshore areas, so anticipating mainly rain
there. Any ice accumulations that occur farther northwest should
be light. Lingering precipitation should exit our southeast
counties Friday morning.

High pressure will arrive for the weekend, bringing primarily
dry weather to the region. Clouds will be on the increase Saturday
night into Sunday, and a few light showers could arrive Sunday
afternoon.

Low pressure will develop in the southern plains Sunday night and
track northeast Monday and Monday night. The GFS and GEFS take the
low into the northern ohio valley, while the ECMWF takes if
farther south, through tennessee. The eventual track will
determine whether or not this only has a glancing blow on the
forecast area, but the best chances should be in southern
counties. Temperatures look warm enough for mainly rain.

Another low develops in the central plains on Tuesday and
tracks into central il on Wednesday. The models are in better
agreement with the track of this system, and suggest that most
of grb CWA should see at least light precipitation, with the
highest pops again in the south. The primary precipitation type
should be rain.

Aviation For 18z TAF issuance
issued at 1213 pm cdt Wed mar 29 2017
a storm system will pass to the south of the area later tonight
and Thursday. This system will bring rain and snow to much of
the area, except possibly the far north. Ceilings should fall into
the MVFR/ifr category across much of the area later this evening
or overnight and continue into much of Thursday. Heaviest snow
totals are expected south of highway 29. Conditions will improve
some Thursday night as the storm pulls away from the area. Also,
gusty northeast winds of 15 to 25 knots are expected Thursday
into Thursday evening across the fox valley and lakeshore region.

Grb watches/warnings/advisories
None.

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.
