637 am est Sun nov 19 2017

Low pressure moving into canada will drive a cold front through
the area this morning. Temperatures will continue to creep up
ahead of the front... With areas of rain through mid morning. The
front will come through with increasing winds... Which may gust
in excess of 40 mph at times through the evening. Temperatures
will continue to fall behind the front and gusty winds will
linger right through Monday. We will get a brief warm up on
Tuesday but another cold front moves through on Wednesday with
cold air spilling in for the latter half of the week.

Near term until 6 pm this evening
7am update... Impressively warm temperatures in the 50s now
pushing into the southern portion of the cwa, while to the north
temps in the 30s remain. Have tried to tighten up the
temperature gradient across the area to reflect this but expect
the warmth to rapidly expand northward this morning.

Morning sounding in progress shows 50kts as low as 2500ft so
expect winds will mix to the surface easily. Have increased
gusts slightly to reflect this and the upstream observations of
40kt peak wind.

Prev... Low pressure located over the eastern end of lake
ontario early this morning will move up the st. Lawrence valley
bringing a cold front through the region this afternoon.

The warm front has pushed northwards through the region with
temperatures rising slightly overnight. This has put the entire
region above freezing changing the freezing drizzle and sleet
from earlier tonight over to rain and so the winter weather
advisory will be cancelled with this update.

Warm air has moved in even further aloft with temperatures in
the mid 40s at 4000ft. These warm temperatures will mix down to
the surface as the cold front approaches this morning. The
southern portion of the CWA may reach 50f. The cold front will
cross the region this afternoon. This front is accompanied by a
50-60kt LLJ which will bring scattered wind gusts of 40-45mph
to the surface. These winds will be most favored in the coastal
plain where downsloping will enhance the winds and a wind
advisory remains in place for these area.

Short term 6 pm this evening through 6 pm Monday
Overnight the tight pressure gradient behind the front will
keep winds in the 15-20mph range overnight. Normally this in
combination with the cloud cover would lead to slightly warmer
overnight low temperatures but with the continued cold advection
as temperatures drop to around -13c at 850mb expect the lows to
drop to the teens with wind chill in the single digits in the

Monday will see clearing for all but the international border
as upslope snow showers persist through the start of the
morning. Winds will continue to gust in the 25mph range
throughout the day.

Long term Monday night through Saturday
Tue will bring ridging surface and aloft... Allowing winds to
decrease and temps to cool off Mon night. Return flow quickly
develops tue... Which should be a mild day relative to recent
high temps.

Model guidance in the extended continues the growing consensus
towards a passing trof Wed with low pressure well out to sea.

The main NRN stream S WV trof shears out thru quebec... And so
the frontal passage will be rather weak across the northeast. An
increase in upslope snow showers is likely... But widespread
precipitation is unlikely given the forcing.

One aspect to the keep an eye on however will be trailing energy
in the base of the trof. As it lags it may allow some moisture
from the ocean low to be entrained into the region. This could
bring more precipitation into coastal zones. The multi-model
consensus high chance pop seems reasonable at this range.

Zonal flow aloft continues Thu into fri... With a quick moving
s WV likely to enhance upslope snow showers in that time frame.

Heading into the weekend there remains a strong signal for a
deep ern CONUS trof and low pressure in the vicinity. There
remains a good deal of uncertainty regarding evolution... But
certainly looks like the best chance in the next 7 days of
widespread precip across the region.

Aviation 12z Sunday through Thursday
Short term... Widespread rain and fog has ceilings at ifr to lifr
across the region and will remain so through daybreak. In the
morning, increasing southwesterly winds ahead of the cold front
will help to mix especially teh coastal plain and cloud decks
should increase. Rain may briefly end as temperatures climb in
the warm sector. A cold front will cross the region this
afternoon with brief period of more intense precipitation and
wind gusts to 35kts from the west. The precipitation will end
and winds will diminish as conditions return to a blusteryVFR
overnight and into Monday for all but the northern mountains
where MVFR upslope snow showers remain.

Long term... GenerallyVFR conditions expected this week. In a
pattern dominated by wly flow... Upslope clouds and shsn will be
possible at hie... But otherwise terminals will only see a threat
of flight restrictions on wed. A passing cold front may bring
scattered shra sn... Mainly across the interior... While a low
pressure passes well out to sea. The best chance for local ifr
conditions will be inland where temps will stay cold enough for

Short term... A cold front will cross the waters this afternoon.

Ahead of the front a few gust to 35kts are possible in
southwesterly flow. Winds will abruptly increase with frontal
passage becoming west with gusts to 45kts on the outer waters
and 30kts on the bays. Not out of the question to see one of the
higher elevation observation platforms gust to storm force but
expect mostly widespread gale conditions so have left the gale
warning as is.

Long term... Gale force wind gusts will diminish
outside the bays Mon night. There may be a brief window of sub-
sca gusts before strengthening swly flow approaches 25 kts.

Winds and seas diminish wed.

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.
