Mountain Cedar location(s): Arbuckle Mountains, OK
weather: Tuesday, December 16
– TX/OK: Across the region today winds will be flowing from the north
with sunny to mostly sunny skies. High
temperatures will be in the mid to upper 40s.
Overnight winds will decrease to light and variable conditions with
temperatures into the 30s. To the south, Texas will start the day mostly sunny
but partly cloudy skies that will build in from the southwest. The area will be in the upper 50s and to the
east along the Edwards Plateau edge into the low to mid 60s. Winds will begin from the north and northeast
switching to a more easterly and eventually southeasterly flow overnight. Lows across the area will be in the low to
mid 40’s across the Plateau and in the upper 40’s along the I-35 corridor. Tomorrow will be mostly cloudy to the north
in the Arbuckle region with a chance of showers (40 to 50%) and temperatures in
the mid 40’s with southeasterly breezes.
Across Texas, cloudy conditions will build in with mostly cloudy skies
over the plateau and denser clouds in the surrounding areas. There will be a 40 to 60% chance of rain
across the Edwards Plateau area tomorrow.
The chance of rain increases from south to north. Temperatures will be in the 50’s and winds
will remain from the east to southeast, 5 to 10 mph. Tomorrow night cloudy skies and continued
chance of rain will occur across the area.
Temperatures will remain relatively steady with only a drop of a few
Trajectory weather: Air mass trajectories over the Arbuckle Mountains move
slowly southward on a dominant northerly
air flow today. Skies will be sunny and
highs today will be in the upper 40’s. Winds will begin at levels reaching 10
mph, but towards evening will fall off to light and variable conditions. Overnight clouds will begin to build in with
low temperatures dropping to the mid 30’s.
Tomorrow there will be a 50% chance of showers with cloudy skies
predominating. Winds will be from the
southeast and temperatures will rise into the mid 40’s. Similar conditions will remain overnight with
cloudy conditions, a 50% chance of showers and temperatures in the lower
40s. Winds will remain from the
and tomorrow, the trajectories will remain within the southern Oklahoma to
north-central Texas region. A check
earlier this week showed that the Arbuckle Juniper trees were not ready to shed
pollen and thus conditions are currently poor for pollination, entrainment and
travel from the southern Oklahoma region. OUTLOOK: *** Poor Threat
today and Poor Threat Tomorrow *** Poor conditions for pollen release today and tomorrow. Today and tomorrow light winds and moderate
temperatures provide good conditions for pollen release and entrainment. However, a check earlier in the week shows that
the cones in southern Oklahoma are not yet ripe. Therefore there is little threat from these
trees as a source of pollen. However,
over the past few days, pollen has been noted in Tulsa as well as Oklahoma City
to the north and a number of sites across Texas (see Texas forecast), therefore
symptoms of pollen allergies may be affecting individuals.
