.synopsis...

low pressure around 29.5 inches will continue to progress eastward
into quebec through tonight, bringing gradually diminishing
west-northwesterly winds through tonight. winds then gradually 
shift to southwesterly monday, increasing into monday evening as 
an additional area of low pressure around 29.7 inches progresses 
through the northern canadian prairies into northern ontario. 
winds become northwesterly behind an associated cold front into 
tuesday morning. 

winds diminish through tuesday as high pressure around 30.1 
inches builds into the central plains and mississippi valley. 
light and variable winds persist into wednesday before weak low 
pressure moves east into the middle mississippi valley and 
strengthens, bringing increasing north-northeast winds wednesday 
night through thursday night. low pressure continues to strengthen
as it moves east into the mid-atlantic by thursday night, 
bringing chances for gales to the southern two-thirds of the 
lake. wednesday night through thursday night, a strong north-to-
south band of lake effect rain and snow is expected to develop.
