The new NAM suggests that part of southeastern OK may see more
sleet than earlier expected tomorrow morning. Snowfall totals have
been reduced there. Additionally, it indicates the axis of maximum
snowfall a bit to the northwest of the previous forecast. For
now, the trend will be to decrease snowfall amounts southeast of
central Oklahoma. Areas near, north and west of I-44 will keep
the current forecast for now.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 326 PM CST Tue Feb 4 2020
Mostly cloudy skies clear from west to east and northerly winds will
diminish Wednesday night as high pressure moves over the region.
Very cold temperatures (teens) and low wind chills (single digits)
are expected Wednesday night into early Thursday morning.
Temperatures will trend up beginning Thursday, with slightly
cooler temperatures over snowpacked areas through Friday. The next
cold front is expected early next week and will be relatively
weak with max temperatures dipping into the upper 40s across
northern OK on Tuesday.
An upper level trough is then forecast to descend over California
and then deepen over the four corners region beginning of next
week. There will be a chance for precipitation Monday through
Wednesday as a series of shortwaves rotate around the base of this
longwave. As of now, the greatest chances for precip appear to be
Tuesday and Wednesday.
