Mountain Cedar location(s): Arbuckle Mountains, OK
Regional weather: Wednesday,
January 7 –TX/OK: Across the region today conditions will cool once
again ahead of cold conditions tomorrow.
Skies across Texas will be partly cloudy to mostly sunny. Across the Edwards Plateau temperatures will
be in the 30s for a high, today. The
southernmost areas along the I-35 corridor will approach the low 50s to the
west but remain in the upper 40s through the Austin Metro region and then get
colder further north. Dallas is expected
to only reach the mid-30s and southern Oklahoma will remain in the 20s
today. Throughout the region winds will
be strong with sustained levels of 20 to 30 miles per hour from the north. Across the Edwards Plateau will begin at
moderate levels but by the afternoon sustained winds at 20 to 30 miles per hour
will be boosted by gusts of 40 miles per hour plus. The air will be cold thus most of the
trajectories will remain near the ground as it travels. Tonight, low temperatures will drop into the
mid-twenties in the warmest areas, such as Austin and San Antonio. The remaining areas will be in the
teens. Strong winds will remain blowing
across the region creating DANGEROUS wind chill throughout the region. Tomorrow, Texas will see mostly cloudy
conditions that will thin to the north with southern Oklahoma having mostly
sunny skies. High temperatures will strive
to get to the mid-30s in southern Oklahoma, be in the upper 30s in Dallas, and
stay in the low 40s across the Edwards Plateau and surrounding communities. Winds will remain at moderately strong
conditions with a southerly direction taking over. Tomorrow night mostly cloudy conditions will
build in with areas expecting precipitation.
In the edge communities to the south there will be a 20% chance of rain
or frozen precipitation. There will be a
20% chance of precipitation in the form of snow or sleet across the Dallas/Ft.
Worth region. Winds will be from the
southwest and south at light to moderate conditions.
Trajectory weather: The
air mass over southern Oklahoma today will barely warm throughout the forecast
period. Temperatures will only reach the
mid-20s in southern Oklahoma. Winds will
be picking up to strong conditions from the north as cold air moves into the
region. Overnight cold temperatures
will return with readings in the lower teens. The air will be dense and have
very little lift as it travels. Thursday,
the cold will linger with high temperatures struggling to get to the mid-30s under
mostly sunny skies. Winds will have switched coming from the south at moderate
to light conditions. Overnight, tomorrow,
the area will drop back to the low twenties. The string of cold days and nights
should continue to hinder pollination today as conditions remain below freezing. Similar conditions will occur again tomorrow
and will keep the area remaining in the mid-30 degree range.
OUTLOOK: *** Low Threat today and Low Threat
Tomorrow *** poor conditions for pollen release today and tomorrow with
temperatures near the 20s today and in the mid-30 degree range tomorrow. Over the forecast period winds will be strong
from the north and very cold. Tomorrow
moderate winds are forecast. The cold
conditions are region wide therefore there is little chance of long distance
