Mountain Cedar location(s): Edwards Plateau, Texas.
Regional weather: Thursday,
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 Edwards Plateau will be influenced by mostly cloudy
conditions today. To the southwest
partial clearing will occur during the afternoon. High temperatures today will be in the upper
40s to the north and just around 50 degrees across the southern Edwards
Plateau. Winds will be light from the
north shifting towards an overall southerly flow overnight and into
tomorrow. The trajectories show the
overall northerly flow today will be somewhat stagnant as the trajectories only
flow small distances. Overnight skies
will remain mostly partly cloudy and the low temperatures will be in the 30s
region wide. There may be some light
frost in the area of the central Edwards Plateau. To the south winds will be from the south and
southeast. In the edge communities winds
will continue to move off the Plateau and conditions will be light and
variable. Tomorrow skies will be mostly sunny
and temperatures will rebound back into the mid- to upper 60s with slightly
warmer conditions to the far west (low 70’s).
Winds will remain from the south and southwest at moderate
conditions. Tomorrow night mostly clear
to partly cloudy skies will occur. Low
temperatures will bottom out in the 40s and the overall southerly to
southwesterly winds will remain at light to moderate levels.
OUTLOOK: ***Moderate Threat today and Moderate threat Tomorrow. Conditions
will be marginal for pollen dispersal today with the high temperatures ranging
from the 40s to the 50 degree mark across Texas. Winds will be from the north at moderate
levels in the morning easing to light levels this afternoon. Entrainment
and downwind travel will be affected by cold dense air today that will tend to
flow at or near ground level where impaction against surfaces occurs. Low temperatures tonight will be in the mid
to upper 30s with colder conditions in the center of the Edwards Plateau. Lows will approach freezing in Junction and
other central Edwards Plateau communities.
Tomorrow conditions will warm as the winds switch, coming from the south
overnight. Tomorrow high temperatures
will rebound into the 60s and winds will be moderate moving the atmosphere
northward. 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. We thank you for your support of
