updated aviation portion for 06z TAF issuance

Short term Tonight and Monday
issued at 309 pm cdt Sun may 28 2017
an area of showers moved out of eastern wisconsin by early
afternoon but another round of showers, and thunderstorms, was
moving through north central and parts of central wisconsin. This
second round was associated with a mid level short wave and
surface cold front. The latest rap and hrrr showed the second area
of showers exiting the state by early evening, with convection
that was moving into western wisconsin this afternoon dissipating
or at least weakening considerably with loss of daytime heating.

There looks to be a lull in the convective activity during the
night, but still have some pops mainly across north central
wisconsin closer to the surface and upper level cyclones. The
chance for showers, and some thunderstorms, will increase again on
memorial day with daytime heating destabilizing the atmosphere and
another mid level short wave moving across wisconsin.

A cooler air mass, clouds, and rain will keep temperatures cooler
on memorial day than they were today. Highs are expected to range
from the middle 50s to the middle 60s.

Long term Monday night through Sunday
issued at 309 pm cdt Sun may 28 2017
cyclonic upper flow will keep mostly cloudy and cool
weather across our area through Wednesday along with scattered
showers mostly in the afternoon and evening hours.

Northwest upper flow forecast Thursday and Friday, though
scattered showers or thunderstorms are possible Thursday night
and Friday as a shortwave trough moves through the flow.

Saturday and Sunday's forecast is a little less certain, as the
models have big differences in the movement of upper jet energy
from the plains states. The GFS looks more reasonable with a
chance of showers versus the ECMWF idea of heavy rain Saturday.

Aviation For 06z TAF issuance
issued at 1122 pm cdt Sun may 28 2017
isolated showers andVFR conditions are expected across most
of the region overnight. TheVFR conditions should prevail over
most of northeast and east central wi through the TAF period, but
MVFR ceilings are expected to arrive over north central and
central wi late tonight into Monday morning. Showers will increase
in coverage during the late morning and afternoon on Monday, and
become numerous over north central wi later in the day. The
steadier rain may cause ceilings to drop to ifr at rhi during the
late afternoon and early evening.

Gusty west winds will develop by mid to late morning, and continue
into Monday evening before subsiding.

Marine
Issued at 309 pm cdt Sun may 28 2017
westerly winds, occasionally gusting to near 25 knots, are
expected memorial day.

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.
