Synopsis
Issued at 114 pm edt Thu sep 21 2017
very warm and dry weather will persist into the middle of next week
as high pressure remains parked over the great lakes. Highs will
range from to mid 80s to around 90 with lows in the 60s for the next
several days.

Short term (tonight and Friday)
issued at 306 pm edt Thu sep 21 2017
amazing warmth for late september this aftn with upper 80s to low
90s widespread. In addition substantial boundary layer moisture had
resulted in local heat indicies in excess of 100.

Little change going forward with upper ridge parked overhead and
expect a carbon copy of today.

Long term (Friday through Wednesday)
issued at 306 pm edt Thu sep 21 2017
upper ridge peaks Sat near lake sc before drifting off into the
hudson valley late Sun yet extends broadly westward through the wrn
oh valley. Deep WRN trough is slow to kick ewd given downstream
block between upper ridge and nwd approaching hrcn maria and
reflected in ewd slowing 12z consensus solution. Thus significant
cooling looks delayed until thu. Rain chances relegated to frontal
zone look limited late period owing to upper trough ejecting newd
through the dakotas and poor moisture return and will cap at slight
chance mention at best wed-thu.

Aviation (for the 18z tafs through 18z Friday afternoon)
issued at 114 pm edt Thu sep 21 2017
vfr through the period as ridging dominates.

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.
