.LONG TERM /MONDAY THROUGH THURSDAY/...
...SIGNIFICANT LAKE EFFECT SNOW EVENT CONTINUES TO LOOK FAVORABLE BY
MID WEEK...
Arctic air will continue to pour into the region Tuesday night
through Wednesday night with 850 mb temperatures dropping to near
minus 20C. This will allow for a strong lake response off both Lake
Erie and Lake Ontario during this time period. As is the usually the
case this far in advance, there remains some uncertainty with
respect to exact location of the lake snows, but current lower
resolution models suggesting a general west or west-southwest flow
will dominate for much of the time period before veering northwest
near the end of the event.
It continues to look like all parameters are in place from extreme
over-lake instability, available moisture and position of upper
level features for significant lake snows downwind of both Lake Erie
and Lake Ontario during the Tuesday night through at least the
Wednesday night time frame.
