Mountain Cedar location(s): Arbuckle Mountains, OK
Regional weather: Wednesday, December 31 and Thursday
January 1 – TX/OK: Across the region today poor weather conditions will
occur. Temperatures across the region
will barely get to 40 degrees in the warmest locations with most areas in the
30s and even 20s. In the southern areas
of the Edwards Plateau moisture will begin to build with the chance of frozen
drizzle and sleet in the area.
Temperatures will hover near the freezing point. In the surrounding communities temperatures
will struggle to the 40 degree mark.
Winds will be from the north and northeast at moderate levels (10 to 15
miles per hour). Tonight cloudy
conditions will occur across the region with increasing chances of
precipitation and temperatures in the 20s across the Edwards Plateau and in the
mid-30s in the surrounding communities and north towards the Dallas/Ft. Worth
metro area. On the Plateau there will be
a 50 to 60% chance of precipitation falling as frozen rain or sleet. Winds will remain from the northeast with a
more easterly direction over the Plateau.
Tomorrow the chance of rain will increase with precipitation occurring
across the region. Temperatures will
remain cold with highs in the 30s across the Edwards Plateau and in the
surrounding communities the warmest locals will be in the low 40s. Winds will remain from the east, more towards
the northeast in the surrounding communities and east to southeast over the
Plateau. In southern Oklahoma winds will
be light and variable. Tomorrow night,
the chance of rain across the entire forecast area will increase with
temperatures in the 30s region wide.
Winds will return to a dominant northeasterly direction. With the temperatures near the freezing mark
a mix of frozen precipitation is possible in almost every community over the
forecast period and caution should be taken when outside and on the roads!
Trajectory weather: Air
mass trajectories over southern Oklahoma today will be influenced by cold
conditions with high temperatures today in the low 30s. Tonight there will be a 20% chance of
freezing rain or sleet and lows will reach the mid-20s. Tomorrow the chance of rain increases to 60%
in the form of sleet and freezing rain.
Temperatures will only reach the mid-30s. Tomorrow night will be a repeat with a 50%
chance of freezing rain and sleet with temperatures in the low 30s. There is no expectation of pollen dispersal
from southern Oklahoma in the forecast period today or tomorrow.
OUTLOOK: *** Low Threat Today and Low Threat
Tomorrow *** poor conditions for pollen release today and tomorrow with
temperatures near the freezing point today and in the mid-30s tomorrow. Over the forecast period winds will be light
and variable. The cold conditions are
region wide with a chance of both freezing rain and sleet further south across
central Texas, therefore there is little chance of long distance dispersal.
