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.

Update
A quiet and mild night is on tap. Forecast is in good shape, no
changes at this time.

Aviation(00z tafs)
Vfr conditions are expected through the TAF period. Winds will
remain light, below 10kts.

Marine
The marine dense fog advisory was canceled. Satellite and shore
based cameras indicate fog is not a concern at this time. However,
remain ALERT for its possible development, especially out toward
open water.

Prev discussion (issued 300 pm cdt Wed may 23 2018)
discussion...

today through Thursday night - confidence... Medium
quiet pattern with high pressure continuing to influence our
weather regime. The northwest CWA will be closer to some of the
waa return flow precip, so some small chances there on Thursday
night. Otherwise warm with an onshore component keeping areas
lakeside cooler.

Friday and Friday night - confidence... Medium
as a mid level shortwave and surface 850 feature move through we
will see better chances of shra tsra, especially Friday afternoon
into the evening hours. Seeing some decent CAPE into the southwest
with mid level lapse rates at 7c or a bit better. Shear isn't very
good, but overall think the marginal risk from SPC seems fine at
this point. Cips analogs not too indicative of much.

Saturday - confidence... Medium
warm pattern continues with some surface 850 ridging taking hold.

There are some indications we could be clipped by some shortwave
activity within the northwest flow regime. This is hinted at by
the ECMWF more so than the GFS and NAM at this point where those
models show more ridging and less influence of the shortwave
trough to our north. So will have some additional shra tsra
potential.

Sunday - confidence... Medium
the models show a trough across the area with the GFS generating
more precip than the ecmwf. This looks to be due to an overly
strong vort being painted by the GFS so may not be as widespread
as what is being indicated. The ECMWF and gem look more reasonable
with less precip coverage. However even the ECMWF does have a weak
wave sliding southeast in the flow.

Memorial day through Tuesday night - confidence... Medium
a cooler airmass builds in with the northeast winds and high
pressure ridging into the area. A slower push of the northeast
winds has the GFS generating some precip before the high takes
hold. At this point like the trends of the ECMWF gem so will keep
it dry at this point. High pressure takes hold with a return flow
setting up by Tuesday night as the high shifts further east.

Wednesday - confidence... Medium
better moisture advection in place to suggest a renewed chance of
precip. However main trough axis still proggd to be to our west
aviation(18z tafs)...VFR conditions through the period. Mainly
some high based ac or ci floating through from weakening showers
to our west.

Marine... Have issues a dense fog advisory for the northern two
zones with webcams having showed and visible satellite showing
fog development across the nearshore waters. Have this going into
mid morning Thursday when SREF cig vis probs suggest lower probs
of fog closer to the shore.

Mkx watches warnings advisories
Wi... None.

Lm... None.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
