.PREV DISCUSSION... /Issued 1032 AM CST Sat Jan 14 2017/

DISCUSSION...
Highest areal coverage of precip remains generally to the north of
highway 412 this morning...in the same zone that has seen several
rounds of convective cells move through. That prompted the
warnings and advisories to be extended further southeast into
the early afternoon. Freezing line continues to slowly migrate
back to the northwest...so the latest additions to the warnings
and advisories will continue through 2 pm with the thinking that
those locations will warm above freezing. Original ice storm
warning that runs through 6 am will continue unchanged. Forecast
elements are in line at this time...so no update will be issued at
this time, but instead early afternoon as segments within the
current headlines will be close to expiring. Rest of the weekend
essentially unchanged as warmer air overtakes the entire cwa
Sunday. Main system to begin ejecting northeast at that
time...with additional rainfall expected later Sunday and
continuing into Monday.
