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 Thu may 24 2018
warm weather will remain in place over the area through the next
week. High temperatures will generally be in the 80s everyday.

Humidity levels will increase this weekend, and then drop a bit
early next week.

Rain chances will be rather low much of the weekend, however they
will not be zero. Friday will remain dry, with shower storm chances
increasing a little on Saturday. A majority of the time will remain
dry, especially toward the lakeshore. The chance will be best also
in the afternoon and evening hours. Rain chances will drop by next
Tuesday as a slightly cooler air mass moves in. They will return by
Thursday of next week.

Short term (this evening through Saturday night)
issued at 300 pm edt Thu may 24 2018
no impacts expected through Friday across the area. Shower storm
chances will increase beginning Friday night and linger into
Saturday evening.

Upper ridging situated just west of the area today, will slowly
traverse the state through Friday afternoon. Limited moisture return
through Friday and sufficient subsidence with the ridge will keep
the area dry. A bit more humidity will sneak in on Friday, but will
not be enough to cause rain.

A short wave will approach the area Friday night and Saturday as the
upper ridge shifts east of the area. The better forcing with the
short wave will remain just north of the area. The associated sfc
front will try and drop down into the area, but likely gets hung up
just north with the short wave staying mostly north. This will keep
the better chances for showers storms north Fri night.

Then on Saturday as the sfc wave moves by, wrly winds will likely
stabilize much of the area with flow off of the lake. Inland areas
could see ml capes increase to 1500 j kg before the west winds kick
in. Deep layer shear is fairly weak, so we do not expect anything
organized.

Long term (Sunday through Thursday)
issued at 300 pm edt Thu may 24 2018
we could see an afternoon or evening shower storm Sunday with temps
well into the 80s once again and dew points around 60. The coverage
will once again be limited as there will not really be a good focus,
other than maybe something along the lake breeze or any other
boundary that could form on the small scale.

The chance for afternoon showers storms on Mon has gone down
compared to previous forecasts. The models indicate that a back door
cold front will drop south through the area Mon morning. This will
shunt instability south of the area. High pressure will build in for
tue, along with a NE wind around the high to our north.

The ridge will slip east of the area mid-week next week, and allow
warm and humid conditions to return to the area. Eventually enough
instability will return to bring a chance of an afternoon evening
storm to the area. A short wave looks to come through around the
Thursday time frame, bringing a little better chance of rain.

Aviation (for the 00z tafs through 00z Friday evening)
issued at 745 pm edt Thu may 24 2018
vfr weather is expected tonight and Friday. Some patchy shallow
ground fog cannot be ruled out 08z-13z Friday, but the fog risk
is lower than it has been previous nights. Southerly sfc winds are
expected to be 10 knots or less.

Marine
Issued at 300 pm edt Thu may 24 2018
no headlines expected through the holiday weekend, and likely
through much of next week. Winds will come up some beginning
tonight, and lingering into early Saturday ahead of a weak system.

The strongest winds will stay further north and offshore. Winds and
waves will try to approach advisory criteria, but are expected to
remain short of it at this time.

Winds coming up should keep the fog chances limited over the lake,
even as dew points come up a bit. Can not rule some fog out, but it
should not be significant enough at this time to need another
advisory.

Hydrology
Issued at 300 pm edt Thu may 24 2018
no hydrology issues expected over the next week, and likely beyond.

Any rainfall expected over the next week will be spotty at best, and
thus not cause impacts on the rivers and streams. The higher levels
currently on the rivers and streams will only fall through next
week.

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.
