Aviation(06z tafs)
Vfr conditions are expected through the TAF period. A mid level
shortwave pushing into the area Saturday afternoon could bring
some isolated to scattered showers and thunderstorms from about
mid afternoon into the early evening.

update...

satellite imagery shows the diurnally supported clouds and showers
are diminishing with darkness moving in. Rinse and repeat for
tomorrow, though the strength of Saturday's afternoon evening
shortwave will be stronger, therefore we should see a bit more
coverage across our area by evening. Quiet tonight.

Marine...

winds will continue to diminish this evening. Winds will be
persistently out of the west the next few days, but should remain
below small craft advisory levels. The westerly flow will keep
waves close to shore below 1 foot.

short term...

tonight and Saturday... Forecast confidence is high:
finally seeing a few showers upstream with the arrival a weak wave
and a cooler airmass. Left some small shower chances in mainly the
northwest half of the forecast area for late afternoon and early
evening. Dry weather is then expected late evening into Saturday
morning.

Should see another wave push through Saturday, bringing more
shower chances in the afternoon into evening. Shower coverage
looks very isolated through mid-afternoon, with higher coverage
moving in from the west by late afternoon with the better forcing.

Showers should diminish as they move eastward during the early
evening hours and daytime heating is lost.

Cooler temps are expected tomorrow, with highs in the upper 60s to
near 70.

Long term...

Sunday through Tuesday... Forecast confidence is high:
more shortwaves will bring mainly afternoon shower and isolated
storm chances Sunday and Monday. Below normal temps will continue
for the first two days of the week.

Southerly low level flow will return Tuesday in advance of
approaching low pressure, bringing temps back into the 70s, just a
couple few degrees shy of normal values. Looks like a pleasant day
with mostly sunny skies expected.

Wednesday through Friday... Forecast confidence is medium:
the pattern will turn more active for the second half of the week.

Multiple rounds of showers and storms seem likely, with deeper
moisture and more instability returning to the region. Right now,
it looks like the best chance for storms will be later Wednesday
into early Thursday and again Thursday night into Friday. There
are timing placement differences among models with the low
pressure systems progged to move through, so plenty of time for
the finer details to change. Should see temps around normal for
this period.

Aviation(18z tafs)...

vfr conditions are expected to prevail through Saturday. Weak
shortwaves late this afternoon and again tomorrow afternoon will
bring sct to bkn 4-5 kft cumulus and isolated showers. A rumble of
thunder is not out the question.

Marine...

gusts to 25 knots still looks reasonable into early evening north
of port washington, so kept the advisory going. Could see a gust
or two to 25 knots south of there, but generally gusts there will
remain up to 20 knots.

Winds will remain persistently west to northwest at 10-20 knots
the next couple days, but should be just below advisory levels.

Mkx watches warnings advisories
Wi... None.

Lm... None.

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.
