Synopsis
Low pressure across the eastern great lakes will move east to
the coast today. A cold front will drop into the area behind
the low. A clipper system will move across the great lakes
tonight dragging another cold front through the region. Cold but
dry conditions are expected thanksgiving.

Near term through Wednesday
For today, an upper trough moving through the great lakes
combined with a surface low to our northeast was bringing light
snow to the region overnight. This should come to an end
northwest before dawn but will linger into the morning hours
east. Not really looking for any significant accums. Main
question is of potential lake enhancement. Best moisture is over
the snowbelt and the lake through about 18z with drying moving
in there after. Temps at 850mb never really get cold enough for
true lake effect but with lift and moisture in the favorable
snow growth zone through the morning expect best enhancement to
occur then. Through the afternoon 850mb temps continue to cool
to around -10c by evening but drier air moves in aloft and
dendrite growth is lost. Instability will remain at conditional
through the day and winds also shift from west, to northwest,
and then back to west through the day as a trough moves through
so limited time to set up bands. Will have accums in grids at 1
to 2 inches today across the snow belt with a 1 to 3 inch inland
eastern erie county. For tonight drying moves in with a ridge of
high pressure extending in from the southwest. This breaks down
quickly as another clipper moves through the lakes. Associated
moisture is limited but sufficient for additional lake effect
snow. Will have likely to categorical pops in the snowbelt with
another 1 to 3 the most likely outcome.

Short term Wednesday night through Friday
The short term forecast begins on Wednesday night with the region
behind a cold front. Cold air advection in northwest flow over the
great lakes will usher in some cold, dry arctic air into the region.

There is a brief window for some lake effect on Wednesday night as
northwest flow is a favorable fetch for lake effect off lakes huron
and erie but the moisture off these two lake will have to fight off
quite a bit of dry air behind the front, while flow continues to
veer overnight. For now, will have a chance pop in the snow belt
with up to an inch of snow accumulation for Wednesday night, as
there is a window for lake effect but enough to keep it from getting
out of control.

Arctic high pressure will build south over the region for
thanksgiving day. This will keep the area dry, but most notably,
temperatures of -10 to -17c at 850 mb will translate to high
temperatures in the 20s. If this holds, it could be the coldest
thanksgiving on record for several areas (lowest maximum
temperature), so stay tuned for potential climate records. High
pressure will shift east on Friday as a warm front moves into the
region. Rain should hold off until Friday night, as an upper ridge
will still be in place over the region. Temperatures will recover 10-
15 degrees on Friday with the air air advection and southerly flow,
but highs will still run below normal in the upper 30s to lower
40s.

Long term Friday night through Monday
The long term forecast period looks unsettled to say the least for
this weekend. An upper trough digs into the great lakes region
Friday night into Saturday supporting a warm front. This upper level
energy should be enough to generate widespread rain on Saturday,
diminishing on Saturday night. Temperatures may actually be back
around normal for the weekend, close to 50 in many spots... Of
course, these warmer temperatures will be spoiled by rain.

Weak high pressure attempts to briefly build into the forecast area
on Sunday, which should allow at least the first half of Sunday to
be dry. However, a deep trough will dig across the central conus
supporting a surface low over the southern plains, which could
impact the region early next week. This system could draw some cold
air back into the region so p-type is going to be an issue and
something to look out for early next week. All of rain, snow, and
mixed precipitation will be a possibility depending on the track of
the low and how fast slow warmer air moves out of the region.

Temperatures will begin falling back down below normal into the
low to mid 40s.

Marine
A cold front moving across the lake this morning will exit southeast
of the lake by later this afternoon. Weak high pressure will attempt
to build back in behind this front but a much stronger, arctic cold
front will cross the lake on Wednesday. Once the first cold front
crosses the lake today, winds and waves will be on the increase and
remain strong through at least Wednesday night. The strongest winds
will be on Wednesday with the second cold front when there could be
gusts to 35 knots at times. Have gone ahead and issued a small craft
advisory for all of lake erie through Wednesday night. The central
basin will see the waves reach SCA criteria by late morning before
building east as the cold front clears the lake. Westerly flow will
increase late this afternoon so will start the central basin early
for the waves but everyone will be reaching SCA criteria by sunset.

High pressure will build behind the cold front on Thursday and winds
should settle to light and variable and waves will subside on the
lake. A warm front will approach the lake for the weekend bringing
southerly flow to the area.
