Mountain Cedar location(s): Arbuckle Mountains, OK
Monday, February 10 – TX/OK: Across
the region today conditions will be sunny and mostly sunny with temperatures in
the upper 40s into the mid- 50s. Skies
will be clear after the weekend rains that covered most of the region. The temperatures will be in the 50s across
the Edwards Plateau with temperatures only in the 40s in the Dallas/Ft. Worth
area northward into Oklahoma. Winds will
begin the day from the north and northeast.
To the south a southerly wind will begin to take over and my tonight
there will be an overall southerly flow over the region. Tonight, with the change in the flow partly
cloudy and mostly cloudy skies will begin to build. Low temperatures tonight will be in the mid-
30s. Winds will be from the south and
southeast at light levels. The exception
will be the western Plateau where winds will be more moderate blowing from 5 to
15 miles per hour. Tomorrow, partly cloudy to mostly cloudy conditions will
build over the Edwards Plateau. There
will be a 40% to 50% chance of rain and showers in the communities surrounding
the southern and eastern edge of the Plateau.
From the Dallas/Ft. Worth area northward skies will remain sunny. Temperatures across the region will be in the
50s, and winds will be moderate from the south across the entire region,
building towards the afternoon. Tomorrow
night the mostly cloudy to cloudy conditions will remain across the Edwards
Plateau. The chance of showers will
remain and lows will be in the lower 40s.
Winds will remain from the south at moderate conditions. To the north skies will be mostly clear with
temperatures at about 40 degrees with southerly winds.
Trajectory weather: Air
mass trajectories over the Arbuckle Mountains will be influenced by clear sunny
skies today and tomorrow. High temperatures
today will be in the low 40s with a light wind from the North at 10 miles per
hour. Tonight clear skies will allow
temperatures to fall to about 30 degrees.
Winds will be light and variable.
Tomorrow sunny skies will allow temperatures to climb into the 50s. Winds will be building from the south at 10
to 15 miles per hour. Tomorrow night
mostly clear skies will occur with temperatures falling to the 40 degree
mark. Conditions for pollen release, entrainment and
travel will be good, however the winds are dense and flowing near ground level,
thus entrained pollen will be subjected to impaction, thus reducing the overall
OUTLOOK: *** Moderate Threat today and High threat Tomorrow. Conditions will be poor for pollen
dispersal with high temperatures only in the low 40s. Entrainment and downwind travel will also be
affected by the dense air flowing at or near ground level where impaction against
objects takes pollen out of the airstream.
Low temperatures tonight will be around 30 degrees. Tomorrow conditions improve with highs in the
mid- to upper 50s. Winds will build to
moderate levels from the south. Tomorrow
night lows will be in the 40 degree range with light winds from the south. The trajectories will be flowing towards the north,
however the air will remain dense and near the ground surface. Cold conditions today will ramp back on the
amount of pollen that get entrained and delivered downwind, however tomorrow
conditions should improve with warmer temperatures. Trajectory Start (s) (shown by black star on map): Davis, OK.
