Mountain Cedar location(s): Arbuckle Mountains, OK
Saturday, January 3 and Sunday
January 4 – TX/OK: Across the region today conditions will be warming
from the colder conditions over New Year’s day and yesterday. Today will be warmer across the region and
then cool once again tomorrow. Mostly
cloudy conditions and a chance of precipitation this morning will remain in the
southern Oklahoma area. Oklahoma City
will still have a 30% chance of snow or rain.
To the south the day will begin with mostly to partly cloudy skies that
will be clearing for sunny conditions most of the day. Temperatures will climb to the mid-50s across
the Plateau. In the surrounding communities temperatures will get above the 60
degree mark. Winds will be from the west
at light conditions but climb to moderate strengths is the afternoon. Tonight mostly clear to clear skies will
prevail with low temperatures in the 20s across the Plateau and the mid-30s in
the edge communities. In southern
Oklahoma, partly cloudy skies will occur with low temperatures in the lower
20s. Across the region the westerly flow
that occurred during the day will be replaced by a dominant northwesterly
breeze at light conditions. Tomorrow
sunny skies should prevail across the entire forecast area. However, moderate winds from the north will dominate and thus
temperatures will struggle to get into the 40’s. Only in the southern edge areas of the
Edwards Plateau are temperatures in the 50s expected. To the north winds will become moderate, with
gusts of 30 miles per hour expected.
Sunday night low temperatures take over once again with clear
skies. Across the Plateau and in the edge
communities low temperatures are expected to be in the 20s, and northern Texas
into Oklahoma will see readings in the teens.
Trajectory weather: Air
mass trajectories move to the northeast. Temperatures over southern Oklahoma today will barely warm with a
lingering chance of precipitation this morning.
Temperatures will rise into the mid-40s in southern Oklahoma. Winds will be light and variable then picking
up tonight coming from the northwest. Overnight cold temperatures will return with
readings in the low 20s. The air will be dense and have very little lift as it
travels. Sunday, the cold will linger
with high temperatures in the 30s under sunny skies. Winds will remain from the
north, moving anything entrained in the atmosphere southward. Winds will be moderate with gusty conditions
towards the south around the Dallas/Fr.
Worth metro region. Overnight, tomorrow,
clear skies and cold conditions will bring
temperatures back to the teens in the area. The string of cold days and nights
along with the precipitation should hinder pollination today as conditions
barely get to the mid-40s. The return to
colder conditions tomorrow will keep the area remaining in the 30 degree range.
OUTLOOK: *** Low Threat Today and Low Threat
Tomorrow *** poor conditions for pollen release today and tomorrow with the tree
populations having been exposed to prolonged cold conditions. It usually takes a day or two for significant
pollination to occur after such events.
Today temperatures will barely get into the 40s and then only into the
30s tomorrow. No pollen release is
expected from the southern Oklahoma population. In addition, the air
trajectories show that the air is dense and will stay close to the ground, a
process that further eliminates an entrained material. Trajectory Start (s) (shown by black star on map): Davis, OK.
