Mountain Cedar location(s): Edwards Plateau, Texas.
Regional weather: Wednesday,
December 31 and Thursday January 1 – TX/OK: Across the region today poor
weather conditions will occur.
Temperatures across the region will barely get to 40 degrees in the
warmest locations with most areas in the 30s and even 20s. In the southern areas of the Edwards Plateau
moisture will begin to build with the chance of frozen drizzle and sleet in the
area. Temperatures will hover near the
freezing point. In the surrounding
communities temperatures will struggle to the 40 degree mark. Winds will be from the north and northeast at
moderate levels (10 to 15 miles per hour).
Tonight cloudy conditions will occur across the region with increasing
chances of precipitation and temperatures in the 20s across the Edwards Plateau
and in the mid-30s in the surrounding communities and north towards the
Dallas/Ft. Worth metro area. On the
Plateau there will be a 50 to 60% chance of precipitation falling as frozen
rain or sleet. Winds will remain from
the northeast with a more easterly direction over the Plateau. Tomorrow the chance of rain will increase
with precipitation occurring across the region.
Temperatures will remain cold with highs in the 30s across the Edwards
Plateau and in the surrounding communities the warmest locals will be in the
low 40s. Winds will remain from the
east, more towards the northeast in the surrounding communities and east to
southeast over the Plateau. In southern
Oklahoma winds will be light and variable.
Tomorrow night, the chance of rain across the entire forecast area will
increase with temperatures in the 30s region wide. Winds will return to a dominant northeasterly
direction. With the temperatures near
the freezing mark a mix of frozen precipitation is possible in almost every
community over the forecast period and caution should be taken when outside and
on the roads!
Trajectory weather: Air
mass trajectories over Texas today will be influenced by cold conditions with
high temperatures today struggling to get to 40 in the warmest areas. Tonight there will be an increasing chance of
freezing rain or sleet and lows will reach the mid-20s over the Plateau and
mid-30s in the surrounding communities.
Tomorrow the chance of rain increases region wide with all areas
potentially experiencing sleet and freezing rain. Temperatures will once again only reach the
40 degree mark in the warmest areas.
Tomorrow night will be a repeat with cold conditions and most lows in the lower 30s. However, a greater chances of rain will
continue to fall as partially frozen precipitation. There
is no expectation of pollen dispersal from southern Oklahoma in the forecast
period today or tomorrow.
OUTLOOK: ****** Low Threat Today and Low Threat
Tomorrow *** poor conditions for pollen release today and tomorrow with
temperatures near the freezing point today and struggling to get to 40 degrees tomorrow. Over the forecast period winds will be from
the northeast. The cold conditions are
region wide with a chance of both freezing rain and sleet across Texas,
therefore there is little chance of long distance dispersal.
