Mountain Cedar location(s): Arbuckle Mountains, OK
January 30 and Sunday, February 1 – TX/OK: Across the region today
conditions will be cloudy with rain. The
rainy conditions will occur today, tonight, tomorrow and finally begin to trail
off tomorrow afternoon and evening.
Today temperatures will be in the 50s across the region with moderate
winds form the southeast. The chance of
rain varies from 60% in the Dallas/Ft. Worth area to 100% across the southern
Edwards Plateau. In Oklahoma there will
be an 80% chance of rain. Tonight rain
will continue with temperatures across central Texas in the mid-50s. It will be in the upper 40s in north Texas
and mid-to upper 30s in southern Oklahoma.
Winds across the area will be from the south to southeast. Tomorrow the chance of precipitation begins
to decline, but most areas will have a 40% to 80% chance. Temperatures will be slightly warmer with reading
in the mid- to upper- 50s. The edge
communities will be in the low to mid-60s.
The winds will begin to shift. In
the north and in the communities surrounding the Edwards Plateau will remain
from the south and southwest. Some areas
the winds will be quite gusty. On the
Plateau itself, and to the west winds will be from the north and northwest at
light to moderate levels. Tomorrow night
mostly cloudy skies will begin the evening, but by morning skies will be only
partly cloudy. The chance of rain should
be more or less gone from the area.
Temperatures will drop, hovering around the freezing mark, especially on
the Edwards Plateau. Winds will be
moderate to strong from the north.
Trajectory weather: Air
mass trajectories over the Arbuckle Mountains will be influenced by the
moisture in the atmosphere. High temperatures
today will be in the 40s with a light wind from the southeast at 10 miles per
hour. There will be an 80% chance of
rain today and tonight as well as tomorrow.
Cloudy skies will bring moisture in from the southeast and south. By tomorrow night the chance of rain will
have moved out of the region and drying will ensue at the beginning of the week. With the beginning of showers most of the
pollen should be knocked down cleansing the atmosphere. Temperatures will only change a little
staying mostly in the 40s until tomorrow night when clear skies will allow
temperatures to drop into the low 20s.
Conditions for pollen release, entrainment and travel will be very poor,
because of precipitation, over the forecast period.
OUTLOOK: *** Low Threat today and Low threat Tomorrow. Conditions
will be poor for pollen dispersal.
Entrainment and downwind travel will be trivial with the wet conditions
across the region. High temperatures
will remain relatively stable over the next two days with areas in the 40s and
50s. Winds will be from the southeast at
moderate levels today and tonight.
Tomorrow stronger winds will occur to the north of the Edwards
Plateau. On the Plateau winds will be
switching coming out of the north and northwest as the storm system moves to
the east. Trajectory Start (s) (shown by black star on map): Davis, OK.
