Messy aviation forecast over the next 12-24 hours is shaping up
across the Upper Mississippi Valley. A deck of LIFR to MVFR
stratus is currently situated over the area with a few breaks
to allow for transient VFR conditions at times. Precipitation
begins to move in later this afternoon from the northwest.
Precipitation will likely start in the form of snow and freezing
rain with a transition to rain/snow this evening. As cold air
begins to move in on the back side of this system, precipitation
will change over the snow overnight. CIGs and visibilities will
likely remain in the MVFR to low end-IFR range (some high-end
LIFR possible) for much of the period with slight improvement
expected after 12Z. Winds are expected to pick up quite a bit
overnight with some blowing snow potential, especially for areas
along and west of the Mississippi (including the RST terminal).
Wind gusts for the overnight time period will be in the 35-45
kt range west of the river with 25-35 kt gusts possible along
and east of the river. Southerly winds at the start of the
period will gradually veer to the west/northwest this evening
and into the overnight period with speeds on the rise starting
later this afternoon.
