Great disco from CLE
LONG TERM /THURSDAY THROUGH SUNDAY/...
By Thursday, a deep and elongated upper-level trough moves east across the Great Plains, producing strong southerly flow with a
Gulf of Mexico connection. This will result in a moisture-rich low pressure system developing over the lower Mississippi Valley
Wednesday night and steadily deepening as it progresses northeast across the Tennessee/Ohio Valley on Thursday and to
the New England coast by Friday or Saturday, depending on which model you look at. Given the high moisture content, strong
synoptic-scale forcing, and favorable surface low track southeast of our forecast area (something that could certainly
change though), this has the potential to be our best snow-producer of the winter for areas outside of the snowbelt, an
achievement that won`t be very difficult due to the lackluster winter so far. Snow and ice will both be on the table for
Wednesday night through early Friday depending on the surface temperatures and vertical temperature. It`s important to note
that while there is potential for a significant winter storm to impact the region, there is still a lot of uncertainty. Model
guidance are still producing widely-varying low pressure tracks which could greatly alter the forecast. For now, it will be
important to monitor the forecast for this time period and planahead if you have travel plans.
