forecast discussion for routine afternoon forecast issuance

Short term Tonight and Friday
issued at 231 pm cdt Thu mar 30 2017
low pressure moving south of wisconsin this afternoon will
continue to bring rain and snow into central and northeast
wisconsin into late evening. There could be some minor
accumulation of snow from green bay to marinette into door county
this evening, but should be just mainly on grassy surfaces. There
could be a few slick spots on the roads if more intense
precipitation rates fall over the same area for a period of time.

The precipitation should taper off to drizzle late tonight or
Friday morning as drier air begins to filter into the region
from the northeast and east. Skies will become mostly sunny
from north to south as the afternoon progresses. Leaned toward
the warmer met guidance north and west of the fox valley for
highs on Friday. Stayed near guidance across the fox valley
and lakeshore due to northeast winds off the cooler waters.

Long term Friday night through Thursday
issued at 231 pm cdt Thu mar 30 2017
the main forecast concerns include determining how much of the
weekend will remain dry, followed by the track and precipitation
trends with two low pressure systems next week.

High pressure will arrive for the weekend, bringing primarily dry
weather to the region. Clouds will be on the increase on Sunday as
return flow and associated WAA increases on the back side of the
retreating surface high. Models are in general agreement that
showers will develop Sunday afternoon, aided by the arrival of a
jet streak aloft. The shower chances will continue Sunday night
and early Monday as a short-wave trof and surface cold front move
through the western great lakes.

Low pressure will develop in the southern plains Sunday night and
track northeast Monday and Monday night. Models vary wildly on the
track of the low, with the GFS ensemble mean bringing it into the
great lakes region, while the operational GFS and ECMWF keep it
much farther south. For now, will bank on the farther south track
and keep the forecast area mainly dry from Monday afternoon into
Tuesday.

A second low is expected to develop in the central plains on
Tuesday and track toward southern lake michigan by Wednesday.

Although the gfs/ecmwf are fairly similar with the speed and track
right now, this was not the case with the previous runs, so would
like to see more continuity before raising pops real high in any
given period. If nothing changes, the most concentrated
precipitation should occur in our southern and eastern counties
Tuesday night into Wednesday. A deep upper trof will likely
linger Wednesday night into Thursday, and combine with cyclonic
flow at the surface to continue the shower threat. Will carry
chance or low-end likely pops from Tuesday night through
Thursday, and fine tune as timing becomes clearer with
subsequent forecasts.

Aviation For 18z TAF issuance
issued at 1111 am cdt Thu mar 30 2017
low pressure passing to the south of wisconsin this afternoon will
bring gusty winds and rain/snow to much of the region. Latest
model guidance would suggest little or no precipitation north of
merrill to iron mountain line. To the south, precipitation should
be in the form of mainly rain, expcept in a band from katw/kcli
northeast into northern door county where a rain/snow mix is
expected, and at times may be all snow for a period of time.

Most locations will see ifr/MVFR conditions except over far
north-central wisconsin whereVFR conditions should prevail.

Conditions will improve into theVFR category at all locations
from north to south on Friday. Also, gusty northeast winds will
continue across central and east-central wisconsin into Friday.

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.
