Mountain Cedar location(s): Arbuckle Mountains, OK
February 5 – TX/OK: Across the region today conditions will begin with
mostly sunny skies to the north and mostly cloudy skies across central
Texas. As the day wears on, the
southernmost communities will become partly cloudy or clearing skies. Temperatures today will be in the low 40s to
the north in the border region between Texas and Oklahoma. Northern Texas in and around the Dallas/Ft.
Worth will also be in the low 40s as well.
Across the Edwards Plateau temperatures will be in the low 50s. Winds across the region will be from the north
at moderate levels of 10 to 15 miles per hour.
To the south the winds will begin to switch to a more northeasterly
direction. Tonight skies will be clear
in Oklahoma with the Edwards Plateau being partly cloudy. Low temperatures will be in the 30s. The Plateau will be in the low to mid 30s
whereas the surrounding communities will be in the mid- to upper 30s. Winds will be light and variable with a more
southerly flow. Tomorrow the northern
areas will be sunny and central Texas mostly sunny. Temperatures are going to climb into the 60s
with the western Plateau slightly warmer.
Winds will be from the south across most of the region. The western Edwards Plateau will see winds
from the southwest. Winds will be at 10
to 15 miles per hour across the region.
Tomorrow night from the Dallas/Ft. Worth, towards the west along the
western area of the Edwards Plateau mostly clear to clear skies will
prevail. The edge communities will have
partly cloudy skies. Overnight
temperatures will be in the 40s and winds will be from the south and southwest
at light to moderate conditions.
Trajectory weather: Air
mass trajectories over the Arbuckle Mountains will be influenced by mostly
sunny skies today and tomorrow.
Temperatures today will only make it into the low 40 degree range on
northerly winds. Tonight skies will be
clear and temperatures will drop to the freezing mark on light and variable
winds. Tomorrow sunny skies will occur
with temperatures rebounding into the low 60s.
Winds will be from the south at 10 to 15 miles per hour. Tomorrow night
skies will be clear with temperatures in the mi- 40s. Cold conditions today with temperatures in
the 40s should restrict pollination. The
trajectories from the Arbuckle Mountains move to the slightly southward this
morning then are affected by an overall regional southerly flow tomorrow and
tomorrow night. Trajectories at ground
level show little lift to the atmosphere, therefore it is thought that any
pollen released will probably be removed by impaction.
OUTLOOK: ***Low Threat today and Moderate threat Tomorrow. Conditions
will be better for pollen release and dispersal tomorrow under warmer
conditions. Tomorrow temperatures will be in the mid- 60s with light and
moderate winds from the south will move the atmosphere northward. Entrainment and downwind travel will be
affected by air density today and tomorrow that will tend to flow at or near ground
level where impaction against objects takes pollen out of the airstream. Recently, the pollen total provided by local
samplers has begun to show a significant decrease in Juniper pollen indicating
the end of the juniper season. As we
approach the end of the Juniper season we will no longer provide forecasts this
year after Friday February 6th 2015.
