Cold front currently moving through southeast Oklahoma into far
northwest Arkansas early this morning. Areas of freezing drizzle
will start to tapper off over the next couple hours, but still
some slick spots on area roads, especially northwest of Tulsa.
Skies are expected to clear from northwest to southeast this
morning with mostly sunny skies this afternoon.
Cold conditions will continue tonight into Monday morning as surface
high pressure builds into the region. Complicated forecast expected
on Tuesday, with multiple precip types possible, as upper level
storm system moves into the four corners region. Areas of rain/
freezing rain/sleet are expected to spread north Tuesday morning
given strong lift in association with right rear quad of upper
jet. Temperatures will likely hold or fall to around freezing as
precip develops through the day. Best chance for rain/freezing
rain to transition to snow will likely be in areas north and west
of Tulsa, however point soundings indicate saturation may not
occur in favored dendritic growth zone. Any winter weather threat
will end Tuesday night as upper jet streak lifts northeast.
Still some differences concerning evolution of upper wave moving
out the Baja region Wednesday into Thursday. GFS is more aggressive
with wave, with another round of overrunning precip during the
day Thursday. ECMWF keeps heavier rain well east of the area during
this time, with significant warmup into Friday. Better rain chances
are expected by Saturday as main upper low approaches. Given uncertainties
in the exact track, will continue with chance pops through the remainder
of the extended periods.
