SHORT TERM
(Issued 341 AM CST Mon Dec 11 2023)
Today through Thursday night:
The sfc ridge along the Upper MS River Valley will quickly move ewd today as strong low pressure moves across nrn Manitoba. The increasing swly winds should advect the stratus out of the area if it does not dissipate beforehand. At this time, expect some clearing west and south of Madison by noon, then by middle to late afternoon for far ern WI. Swly winds and warm advection will prevail tnt followed by a dry cold front passage Tue AM. High temps in the lower to middle 30s for Mon-Tue. A sfc ridge passage will then follow for Wed AM with the high to settle over the Ohio River Valley for late Wed into Thu nt. This will support swly winds and warm advection through the period. High temps will return to the 40s for Thu.

LONG TERM
(Issued 341 AM CST Mon Dec 11 2023)
Friday through Sunday:
High pressure will weaken and retreat east over the Ohio River Valley ahead of a shortwave trough that is expected to move southwest over the Great Lakes Friday into Friday night. Models differ on the timing and position of this wave, so have maintained the slight chances (~20%) PoPs that the NBM is suggesting for that time period. Right now, precipitation type will depend upon the timing of the wave. If it comes through during the day, rain will be favored, but if the wave slows and comes overnight Friday night into Saturday, rain-snow mix to snow will be favored. Precipitation in either case should be light.
Following the wave, a brief period of warm advection should occur ahead of a dry cold front. The cold front should swoop through on Sunday bringing cooler air for Monday. Temperatures in the late extended period should be in the low to mid 40s, save for Monday following the front, which may see highs in the mid to upper 30s.

High pressure of 30.2 inches along the Upper Mississippi River Valley this morning will slide southeast to the Ohio River Valley this afternoon, while strong low pressure tracks across far southern Hudson Bay through Tuesday. Thus light to modest northwest winds this morning will back to brisk southwest winds this afternoon and increasing further tonight. A Gale Warning has been issued for the north half of the lake tonight. The winds will veer to west northwest and remain brisk for Tuesday and Tuesday night but remain below gale force. Modest westerly winds are expected for Wednesday as high pressure sets up from northern Illinois into the Ohio River Valley.
