Mountain Cedar location(s): Arbuckle Mountains,
OK
Regional weather: Friday, December 6 TX/OK/AR: Sunny
conditions will prevail across the southern Edwards
Plateau with warming and drying conditions
today and tomorrow. Winds will be light to moderate from the south to southwest
throughout today and into Saturday.
Southeast winds will develop on Saturday along the southern edge of the Edwards
Plateau bringing higher humidity
into San Antonio and Austin
resulting in partly to mostly cloudy conditions Saturday afternoon. To
the north, in Oklahoma and the Ozark
Mountains, winds will be light to moderate from the southwest increasing
to moderate overnight and into Saturday. High temperatures across the Edwards
Plateau and Hill Country will reach
the low to mid 50’stoday and into the mid to upper 50 s tomorrow. Lows overnight
on Friday will be in the upper 30’s to low 40’s across the region. To the
north temperatures will be similar with highs today in the mid to upper 40 s
and low50 s on Saturday. Low temperatures will be in the 30’s
tonight. Throughout the entire region sunny skies will prevail today and
tonight with increasing humidity and partly cloudy skies on
Saturday.
Trajectory weather: The air mass trajectories from the Arbuckle
Mountains move to the northeast
over the Tulsa area and into Missouri. Light
to moderate winds today ill be from the south to southwest. Winds will increase overnight to moderate. Sunny and clear skies today and tonight will
see increased cloudiness on Saturday and humidity begins to rise. A slight warming will occur throughout the
region today and tomorrow
OUTLOOK: ***Low threat today *** unfavorable conditions
for pollen release today. Conditions
in southern Oklahoma will see
temperatures in the 30s and low 40s this morning with the upper 40s this
afternoon. Sunny conditions generally
would lead to some pollen release, however, there
is no indication from our observers that pollination has begun within the trees. Therefore along with the cool temperatures
unfavorable conditions for pollen release are forecast. In addition, the air
trajectory characteristics show little lift in the winds moving over Oklahoma
which is necessary to carry pollen downwind.
Trajectory Start(s) (shown by black star on map): Sulfur,

anticipated future track of released Mountain Cedar pollen, weather conditions
over the region and along the forecast pathway, and an estimated time of
arrival for various metropolitan areas.
