Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Issued at 300 pm edt Wed jul 18 2018
high pressure will provide fair weather and low humidity through
Thursday. Lows tonight will be in the upper 50s with afternoon
highs tomorrow in the mid 80s. A low pressure system will then
move into the great lakes region Friday and stall this weekend
with periodic chances for showers and thunderstorms.

Short term (this evening through Thursday)
issued at 300 pm edt Wed jul 18 2018
midlevel ava and associated subsidence will remain anchored over
the great lakes through tomorrow. Ridge axis does pass our
longitude during the day tomorrow and will allow for some minor
waa with increasingly southerly flow. This will allow us to tack
on a few extra degrees with highs approaching the mid 80s under
partly cloudy skies. Overnight lows similar to last
night... Perhaps a few degrees warmer in spots due to slightly
warmer profiles.

Long term (Thursday night through Wednesday)
issued at 300 pm edt Wed jul 18 2018
situation changes substantially Thursday night as lead theta-e ridge
arrives from approaching closed midlevel circulation on cyclonically
sheared side of seasonably strong upper level jet. This jet will
continue to dig south through the weekend and become increasingly
cutoff from main westerlies along us canada border... Leaving our cwa
in a region of persistent low midlevel cyclonic flow with periodic
showers and possibly a few storms.

Precip chances begin Thu night though will still be a very dry and
stable airmass in place... With relatively weak LLJ moisture
convergence in all but our far W SW CWA late. Chances increase
during the day Fri with some diurnal instability contribution and
approach of midlevel vort lobe. Latest 12z ECMWF has trended toward
the NAM and GFS of a further south track... So trended the forecast
in that direction. Likely pops easily warranted given cva forcing
and decent moisture instability... Though widespread model QPF may
still be a bit overdone. Exact northward extent of main instability
plume still a bit uncertain... But a few strong storms possible in
our far S SW based on current low track timing.

A more stable scenario over the weekend as vertically stacked low
wobbles near just south of cwa. Not expecting any severe weather but
enough low level moisture and daytime heating to support a diurnal
component to highest pops. Best chances currently appear to be sat
as low pressure drifts SE of area on sun. Chances linger over SE on
Monday but should start to see some gradual clearing as upper low
slowly dissipates.

Aviation (for the 06z tafs through 06z Thursday night)
issued at 1255 am edt Thu jul 19 2018
return flow will increase today as a surface high pressure area to
the east of the region continues to retreat to the east. The
gradient should tighten as the next system approaches causing
winds to increase to around 10 knots later today. Have kept
thunder out for now, although a stray storm is possible late in
the TAF period.

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.
