Dry, pleasant weather is expected through the weekend. Rain chances
return on Tuesday with a mid-week frontal passage.
Near term through tonight
High pressure building over the great lakes will continue to filter
in cooler, dry air into the region. Cloud cover will gradually
diminish overnight- leaving most locales cloud-free. Radiational
cooling and much cooler air in place will result in some of the
coolest temps this month. Expect lows in the low mid 50s.
Short term Saturday through Sunday night
Dry, pleasant weather is expected this weekend. High pressure will
slowly drift eastward, placing the CWA in dry north northeast flow.
Temperatures will be rather seasonable, with highs in the 70s on
Saturday and 70s to around 80 on Sunday.
Long term Monday through Friday
A warming, moistening trend is expected early mid next week as the
ridge axis moves east and return flow commences. Southwesterly flow
aloft will increase ahead of a deepening upper low across the
northern us plains and manitoba ontario region of canada.
Precipitation is possible late Monday night into Tuesday as a weak
shortwave and associated warm front move across. However, the main
show will be later on Tuesday into Wednesday. Despite some timing|
differences among the global models, confidence is high with the
passage of a cold front sometime on Wednesday, followed by drier and
more pleasant weather late week as high pressure builds into the
Aviation 19z Friday through Wednesday
Vfr conditions likely through the TAF period, with dry northwest flow
aloft and increasing sfc high pressure.
Patchy fog may develop Saturday morning as clearing clouds and light
winds will allow for efficient radiational cooling. However, models
depict a notable jet developing just above the sfc inversion, which
will make it difficult for the layer to become decoupled and allow
fog formation. Add in some uncertainty in the degree of cloud
clearing and the presence of enough sfc moisture, and confidence
becomes too low for TAF mention.
Vfr expected through the weekend with high pressure the dominant

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
