    Winter 2021-22 Complaint/Banter Thread

    in Lakes/Ohio Valley

    Rant!!!

    I remember a time when we would have a parade of clippers ( what happened to them) and when storms would phase and bring big storms (what happened to them). Outside of last weeks snow we have had nothing even to track and the next 10days to 2 weeks don’t offer much hope. It’s going to be almost the end of January and we will have snow one day this winter. Places in Kentucky and Tennessee will have twice as much snow!!!!

    I think GRR is going to pass 14" for the storm total.  The back edge is only a few miles to the north and creeping closer, but this current band is putting out a grand finale as it exits.  1-2" per hour rates.  Big dendrites.  Super high ratios.

    Good for you enjoy!!!

    Looking forward to the polar vortex visiting at the end of the month with bare ground.

    Next item of note is the potential for a period of robust snow
showers/squalls on the Arctic front late tonight-early Wednesday.
including into Chicago. We wouldn`t be looking at much in the way
of accumulation, though snow could fall heavily for a short period
and coat paved surfaces, which would be problematic as temperatures
plummet through Wednesday morning behind the front. Finally, have
higher confidence in advisory criteria westerly winds (45+ mph
gusts) for much of if not the entire area through early Wednesday
afternoon. For the full forecast package issuance this afternoon,
will be considering a Winter Weather Advisory expansion, as well
as likely issuing a Wind Advisory for the remaining counties.

    New Years Winter Storm

    snippets from KLOT 

    Saturday morning, snow
appears poised to spread quickly from south to north across much
of northern Illinois and far northwestern Indiana and last through
the remainder of the day. The steadiest snow looks to remain
within a 10-12 hour period from roughly noon Saturday to midnight
Sunday, with snow rates of 0.5"/hr prevailing. Heavier snow rates
approaching 1"/hr may develop within transient frontogenetical
bands as well as along the Illinois shoreline of Lake Michigan
where sufficiently cool temperatures will make the marine airmass
unstable within a favorable northeasterly wind trajectory. After
midnight, snow will taper from west to east except along the Lake
Michigan shore where lake enhancement will continue through
daybreak Sunday.
    Snow ratios look to start near 10:1 Saturday afternoon and increase
toward 18:1 Saturday night as the low-level temperature profile
cools.
    The highest confidence area for hitting
warning-level impacts (e.g. where travel would be discouraged
entirely) is actually in Lake County (IL), eastern DuPage County,
and all of Cook County where there appears to be an increasing
chance that lake-enhanced snow rates of 1"/hr will overlap with
blustery northeast winds, leading to low visibility.
