Date Issued: 1 January 2013
Mountain Cedar Location(s): Arbuckle Mountains, OK
Regional Weather: Tuesday, January 1 – TX/OK:
Across the region the weather continues to be seasonally cool with high temperatures to the north just climbing
into the upper 30’s to low 40’s and across Texas temperatures in the 40’s and 50’s today. The southernmost community
of San Antonio will struggle to get much above 60 degrees. Winds will be moderate from the north for the next
two days. Skies will remain partly cloudy with moisture streaming across the region from the southwest. Overnight
areas to the north in Oklahoma and across the Edwards Plateau temperatures will fall into the 20’s. In the communities
surrounding the Edwards Plateau, lows tonight will be in the mid to upper 30’s. Tomorrow partly cloudy to mostly
sunny skies will occur in Oklahoma southward along the eastern edge of the Edwards Plateau. Across the Edwards
Plateau mostly cloudy conditions will occur. Temperatures will cool off another 5 to 10 degrees from today, with
high temperatures in the 40’s region wide, just pushing into the 50’s along the southern edge of the Plateau.
Winds will remain at lite to moderate conditions from the north and northeast. Tomorrow night, mostly to partly
cloudy conditions will occur with temperatures back into the 20’s overnight and slightly warmer conditions in the
communities surrounding the Plateau. Winds will remain from the northeast to the south and from the northwest
further north.
Trajectory weather: Air mass trajectories over the Arbuckle Mountain move southward today crossing over
the Edwards Plateau over the next 48 hours. The atmosphere will be buoyant as upper level moisture continues to
stream in from the southwest and interacts with the dominant cold conditions on the ground from the north and northeast.
Communities across the Edwards Plateau and southward will see the effects of any pollen release. Temperatures
for the next two days will remain in the mid to low 40’s, conditions not particularly conducive for pollen release.
In addition, conditions over the past 3 to 4 days have brought precipitation and cold conditions thus the trees
may be sluggish in releasing any pollen today. However, some local release is always possible and may affect allergy
sufferers in the immediate vicinity. Tonight cold conditions will return with low temperature in the low to mid
20’s.
OUTLOOK: *** Low threat today and Low threat tomorrow *** Poor conditions for
pollen release today with temperatures just getting into the 40’s. Tomorrow temperatures will be in the low 40’s.
Cold conditions and recent rains will dampen any pollen release. Cold conditions will continue today and tomorrow
with overnight low temperatures falling into the low to mid 20’s. Cold air will remain near the ground. For these
reasons there will be poor conditions for entrainment and travel across the region today, tonight, and tomorrow.
Temperatures will mostly be in the 30’s and 40’s today and tonight with moderate wind speeds. Moderate winds
will build again tomorrow along with the return of cold conditions. We are approaching the heart of the historic
pollination season. We continue to have patients contacting the modeling team to report strong allergy symptoms.
Today and tomorrow should provide a nice break for allergy sufferers, but once the region dries out the remaining
pollination season will return.
