Mountain Cedar location(s): Edwards Plateau, Texas.
Regional weather: Saturday,
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 Edwards Plateau will be influenced by the moisture
in the atmosphere. High temperatures
today will be in the 50s and low 60s with a light to moderate wind from the southeast
at 10 to 20 miles per hour. There will
be an 60% to 100% chance of rain today and tonight as well as tomorrow. Cloudy skies will bring moisture in from the southeast
and south over the forecast period. 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 regional rain, most of the pollen should be
knocked down cleansing the atmosphere. Temperatures
will only change a little staying mostly in the 50s until tomorrow night when
clear skies will allow temperatures to drop into the 20s and 30s. 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 50s and
just into the 60s in the southernmost communities. 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 itself winds will be switching
coming out of the north and northwest as the storm system moves to the east.
