Mountain Cedar location(s): Arbuckle Mountains, OK
January 5 – TX/OK: Across the region today conditions will be warming
and sunny compared to the recent colder weather. High temperatures will be in the low 50s
today across the Edwards Plateau and in the surrounding communities. In the Dallas/Fort Worth region north towards
southern Oklahoma, temperatures will top out in the mid- to low 40s. Over the Edwards Plateau winds will begin
light from the south and will build to moderate wind strengths this
afternoon. In the communities
surrounding the Edwards Plateau, winds will be from the northeast switching,
coming from the southeast this afternoon.
In northern Texas and southern Oklahoma, winds will be from the east at
light levels. Tonight, southern Oklahoma
will be clear with temperatures dropping into the upper 20s. Winds will be from the southwest at 10 miles
per hour. Over Texas, temperatures will
be mostly in the low 30’s. Skies will be
mostly clear with winds at light levels form the southwest. Tomorrow, mostly sunny skies will greet the
day. Temperatures are expected to rise
into the low 60s across the Edwards Plateau and in the surrounding communities.
Winds will remain from the southwest at light levels. In southern Oklahoma, temperatures will once
again remain in the low 40s. Winds will
be from the east initially then switching coming from the south. Tomorrow night southern Oklahoma temperatures
will drop back into the teens on moderate northerly winds. Northern Texas, southward across the Edwards
Plateau temperatures will return to the mid- to upper 20s. In the surrounding communities temperatures
will remain above freezing but stay within the 30 degree range.
Trajectory weather: The air mass over southern Oklahoma today will
barely warm throughout the forecast period.
Temperatures will only reach the low-40s in southern Oklahoma. Winds will be light and variable then picking
up tonight coming from the southwest. Overnight cold temperatures will return with
readings in the upper 20s. The air will be dense and have very little lift as
it travels. Tuesday, the cold will
linger with high temperatures in the mid-30s under sunny skies. Winds will be
from the north as colder air moves into the region. Overnight, tomorrow, clear skies and cold conditions will bring temperatures
back to the teens across the area. The string of cold days and nights should
continue to hinder pollination today as conditions barely get to the mid-40s. Similar conditions will occur again tomorrow
and will keep the area remaining in the 40 degree range where pollination is
OUTLOOK: *** Low Threat
today and LowThreat Tomorrow *** poor conditions for pollen release today and tomorrow with the
tree populations having been exposed to prolonged cold conditions. It usually takes a day or two for significant
pollination to occur after such events.
Today temperatures will barely get into the low 40s and then only into
the mid-40s tomorrow. No pollen release
is expected from the southern Oklahoma population. In addition, the air
trajectories show that the air is dense and will stay close to the ground, a
process that further eliminates an entrained material.
