Mountain Cedar location(s): Arbuckle Mountains, OK
January 12 – TX/OK: Across the region today conditions will be warming
with the warmest areas being in Texas and reaching the 50s to low 60s.. Skies across Texas will be mostly cloudy with
a chance of fog this morning in the edge communities from San Antonio to Austin
and further north. The Edwards Plateau
will warm into the low 50s in its central portion whereas to the west
temperatures will remain in the 40s. The
Dallas/Ft Worth metro area as well as further north into southern Oklahoma will
be in the mid- to low 40s. Across the
region winds will be from the north at moderate to strong conditions. Air flow across Texas will be from the north
bringing colder conditions back across the area. Winds will be strong, gusting to 25+ miles
per hour in the edge communities.
Tonight mostly cloudy conditions will remain with temperatures returning
into the mid-to upper 30s in the edge communities and the low 30s across the
Plateau. To the far west low
temperatures will be in the upper 20s.
Winds will continue from the north and northeast at moderate conditions. Winds will remain gusty up to 25 miles per
hour. Tomorrow the influx of cold air
will hold temperatures in the 40s across the Plateau and in the edge
communities. To the north in Dallas/Ft.
Worth, temperatures will remain in the upper 30s, as will the Arbuckle
Mountains in southern Oklahoma. Winds
will be light to moderate from the north to northeast. Tomorrow night temperatures will drop into
the mid-to low 30s and a 20% chance of precipitation will occur over the
southern half of the Edwards Plateau and in the surrounding edge communities as
well. Winds will be very light from the
northeast to east.
Trajectory weather: Air
mass trajectories over southern Oklahoma today will move from the north on moderate
to strong winds. The air will continue
to be cold and dense thus movement at the lowest levels will continue at or
near ground level. Temperatures will
remain cold at the ground, only reaching the 40 degree mark today, and then
cooling to the upper 30s tomorrow. Tonight
temperatures will fall back to the low to mid 20s with moderate north
winds. Tomorrow mostly cloudy skies and
temperatures in the upper 30s are forecast.
Winds will be light from the north.
Tomorrow night there is a 30% chance of snow with low temperatures in
the 20s. Winds will be light and
OUTLOOK: *** Low Threat today and Tomorrow. The tree populations continue to be exposed
to prolonged cold and wet conditions. Today
conditions will remain cold with the high temperature only at 40 degrees and
mostly cloudy skies. Tomorrow
temperatures will only get to the upper 30s under mostly cloudy skies. Tomorrow night, a 30% chance of snow is built
into the forecast. Low temperatures will
be in the upper 20s and winds will be light and variable. The
potential for pollen being released, and entrained in the atmosphere is poor
because of the prolonged period of really bad conditions with low temperatures
and mostly cloudy conditions. The dense
air will move to the south. Any pollen
that gets entrained within the atmosphere will be moving at low levels where
impaction should cause a majority of it to settle relatively close to the
