...DISCUSSION...
A mature mid-latitude cyclone is forecast to gradually shift
eastward across southern Quebec on D4/Tuesday and D5/Wednesday as a
series of shortwave troughs rotate through the enhanced mid-level
flow throughout its base. At the same time, expansive upper ridging
will build eastward. By early D6/Thursday, this ridging is expected
to extend from the Southwest northward across the Plains and Upper
MS Valley into Ontario. Further eastward progression/expansion of
this ridging is anticipated on D7/Friday, although some dampening is
possible along its northern periphery over the Canadian Prairies.
This pattern evolution will maintain a stable airmass across the
majority of the CONUS.

The only exception is across FL, where a tropical airmass will
remain in place throughout the period. Additionally, medium-range
guidance continues to suggest tropical cyclone development could
occur over the Gulf of Mexico, with potential impacts across the FL
Peninsula on D4/Tuesday and D5/Wednesday.
