Winter Weather Discussion 2010-1-7

Winter Weather Discussion for January 28-29, 2010.
Valid: 2010-01-28

*Significant winter weather event underway*
*This is a life threatening situation*

Highlights:

– Winter Storm Warning continues for much of Oklahoma, north of a line
from Lawton to Eufaula to Muldrow. A mixed bag of precipitation
across the state. As mentioned previously, excessive snowfall is
likely in northwest Oklahoma and panhandle with 8-12 inches
accumulation likely. Immediately south of that area there will be a
swath of primarily sleet turning to snow later today. The I-44
corridor is now facing an ice storm with accumulations at least ¼
inches and likely upwards near 1 inch. This area will change to sleet
later today and end with snow late tonight.

– Winds are out of the northeast at 15-25mph across the state and will
continue for the next few hours. This will exacerbate ice loading on
exposed objects.

Discussion:

Surface freezing line runs from Walters to Duncan to Holdenville to
near Muskogee to north of Cookson. This line is much farther south
than originally progged at 9am. Freezing rain is noted in Oklahoma
City with accumulations already starting on exposed objects. 12z NAM
is similar with QPF but much different on the 700mb dryslot. This
would seemingly prolong the precipitation into late Friday. For now,
the well talked about and forecast ice storm is underway in
western/central Oklahoma.
