.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
Deep digging upper level trough through the Central Plains states
will gradually shift east and become negatively tilted slightly.
This will result in surface low pressure over the delta region of
the Mississippi River to move northeast toward West Virginia by
Monday evening followed by a secondary stronger low pressure system.
The first low will be in response to an upper level positive
vorticity maximum sliding into the southern Great Lakes region and
then the secondary low deepens as the upper trough becomes more
negatively tilted. Typically, deepening low tracks through the
Panhandle of West Virginia are ideal tracks for our forecast area as
this places the best frontogenetical forcing over our area. Latest
upper air model soundings suggest this forcing axis will remain just
south of our area as the secondary low moves northeast through
Virginia. Current thinking was to lower snow accumulations slightly
due to the above comments and this is in line with the WPC guidance.
Will not be issuing any headlines at this time due to the long
duration snow accumulation event and will not exceed the 8 inches in
24 hour time frame. However, potential for total snow accumulations
up to 9 inches possible in the east with gradually lowering amounts
to 4 inch totals in the Toledo to Findlay areas.
