updated aviation portion for 00z TAF issuance

Short term Tonight and Friday
issued at 241 pm cdt Thu aug 22 2019
an upper level trough was moving through the forecast area this
afternoon, and producing abundant cloud cover and isolated
showers. With a canadian air mass in place, mostly cloudy skies
and northeast winds, temperatures were mostly in the 60s.

Isolated showers are expected to dissipate by sunset, as the
short-wave trof departs the region. Clearing skies will occur
this evening, leaving mostly clear skies and light winds for the
overnight period. This will lead to the potential for fog
development, especially over north central wi, where the ridge
axis will reside late tonight. Could see some patchy dense fog
there between 4 am and 8 am. Low temperatures will drop into the
40s and lower 50s over most of the forecast area. However, the
typical cold spots in north central wi should see readings in the
mid to upper 30s, which may result in patchy frost development
late tonight near the upper michigan border.

Friday looks to be a pleasant day, with light winds and scattered
cumulus clouds. With abundant sunshine expected, highs will be a
little warmer, mainly in the upper 60s to middle 70s.

Long term Friday night through Thursday
issued at 241 pm cdt Thu aug 22 2019
tranquil, somewhat cool conditions are forecast through the
weekend as surface and upper ridging to reside just to our east.

Models continue to show a strengthening upper trough over south-
central canada north-central u.S. Early next week that will bring
northeast wi a good chance of seeing showers some thunderstorms
Monday afternoon night. The forecast becomes more uncertain headed
into mid-week as the models disagree on the depth of the upper
trough over the great lakes. A deeper trough would suggest higher
precipitation chances, while a flatter trough would hedge toward
drier conditions. Temperatures appear to be at or below normal
this weekend, get close to normal early week, then trend back down
mid-week.

High pressure at the surface to stretch from the western great
lakes northeast into eastern ontario, while an upper ridge to
reside over the upper midwest western great lakes Friday night.

This will translate into mostly clear skies, light winds and cool
conditions. Min temperatures to be in the lower to middle 40s
north, upper 40s to lower 50s south. The sprawling surface high to
extend from the western great lakes to southeast canada northeast
conus on Saturday, while the upper ridge slides into the great
lakes region. Look for mostly sunny skies (some fair weather cu),
an east-southeast wind of 5-10 mph and MAX temperatures mainly in
the lower 70s, except upper 60s along lake mi.

Both the surface and upper ridge will gradually shift to the east
during the latter half of the upcoming weekend. Winds are expected
to be south-southeast which will tap into slightly warmer more
moist air mass. Dry conditions to prevail through Sunday with min
temperatures Saturday night in the upper 40s to around 50 degrees
north, lower to middle 50s south. MAX temperatures for Sunday to
range from the lower 70s near lake mi, mainly middle 70s inland.

The high pressure finally begins to lose its influence over
northeast wi Sunday night as an upper trough digs southeast into
the northern plains, accompanied by a cold front. We should see a
gradual increase in clouds with a slight chance of showers
thunderstorms after midnight over central wi. This upper trough
cold front combination push east into the upper midwest on Monday
with showers slight chance of thunderstorms overspreading the
forecast area, especially during the afternoon hours. Higher
values of CAPE and shear to remain to our west and south on
Monday, thus any severe threat appears to be rather low. Max
temperatures on Monday to be in the lower 70s north-central wi
near lake mi, middle to upper 70s elsewhere.

This system swings into the great lakes by Monday evening with the
upper trough becoming negatively-tilted later Monday night.

Showers few storms to continue into Monday evening, then become
more scattered over central wi after midnight as the system begins
to shift east. Pw values climb to around 1.5" by late Monday into
Monday night, thus several bouts of heavy rain will be possible.

By Tuesday, models show the upper trough to begin closing off into
an upper low over western ontario with a lingering cyclonic flow
into the great lakes. Cannot rule out a few showers, mainly over
northern wi Tuesday afternoon. MAX temperatures for Tuesday to be
around 70 degrees north-central, lower to middle 70s elsewhere.

Models continue to have timing issues with regards to timing
individual shortwaves riding southeast within the mean northwest
flow aloft. The GFS suggests one shortwave to arrive on Wednesday,
while the ECMWF has nothing. For now, will use the consensus
solution which places slight chance pops for Wednesday Wednesday
night. By next Thursday, the cyclonic flow is weaker and we may be
able to sneak by with a dry forecast. MAX temperatures for both
Wednesday and Thursday are forecast to be a little below normal
with readings primarily in the upper 60s to lower 70s.

Aviation For 00z TAF issuance
issued at 622 pm cdt Thu aug 22 2019
vfr conditions expected through much of the period, except from
07z to 14z when patchy fog with ifr MVFR CIGS and visibilities
are expected. Clouds from 5,000 to 7,000 feet should erode
this evening, with fair weather cumulus clouds expected between
3,500 and 5,000 feet after 15z on Friday.

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.
