Mountain Cedar location(s): Edwards Plateau, Texas.
Regional weather: Wednesday,
January 14 – TX/OK: Across the region today conditions will be cool today and then begin to warm up
tomorrow. Across the Edwards Plateau and
in the surrounding communities cloudy to mostly cloudy conditions will occur. In Austin to San Antonio there will be a
slight chance of rain and drizzle. High
temperatures will be in the 40s across the forecast area. Winds will be light from the north to
northeast. In Southern Oklahoma high
temperatures will barely get to 40 degrees today. Winds will be light and variable. Tonight the Edwards Plateau will start the
day with cloudy and mostly cloudy skies.
Lows over the Plateau will dip into the 20s once again. The surrounding communities will be in the 30s
towards the north. North of the
Dallas/Ft. Worth metro region temperatures will return to the 20s. Winds will be from the north and northwest at
light conditions. Tomorrow the Edwards
Plateau will see warming conditions.
Partly cloudy conditions early will give way to mostly sunny and clear
conditions. For the first time in some
time, temperatures will warm into the mid to upper 50s’ Winds will be moderate from 5 to 10 miles per
hour. In southern Oklahoma high
temperatures will be in the lower 50s under sunny skies. Winds will be light and variable. Tomorrow night mostly clear conditions will
prevail with mostly clear skies and thus cooling. Most areas will be in the 30s from southern
Oklahoma south across portions of the northern Edwards Plateau then southward
around the edge of the Plateau. On the
Plateau especially towards the west temperature will cool into the
mid-20s. Winds will be light and
somewhat mixed although most flow will come from the north and northwest.
Air mass trajectories over Texas will
move from the north toward the south today, tonight, tomorrow and tomorrow
night. The atmosphere will continue to
be cold and thus the air will be dense and generally moving from the north
towards the south at or near the elevation that it starts at. Temperatures today will be in the 40s for the
high temperature region wide. Today
should repeat yesterday in terms of the conditions. There have been a number of cold days
stretching back, in which little pollen has been recorded. Today will be similar. Tomorrow warmer conditions will occur with at
least a 10 degree rise and an overall flow from the north. With the warming conditions the release of
pollen should be much more common and with winds in the 5 to 10 miles per hour
range some long distance dispersal is expected.
Overnight tomorrow, lows will
return to the 20s on the western Plateau and 30s across the remaining
areas. Winds will become very light and
today and High threat Tomorrow.
The tree populations will be exposed to potential damp conditions today. Today
conditions will remain cold with the high temperature only in the 40 degree
range and mostly cloudy skies. In the surrounding
communities there is a slight chance of rain or drizzle that may contribute to
cleansing the atmosphere of any pollen that does get entrained. Tomorrow temperatures will rise into the 50s
with light to moderate winds. Skies will
be clear and sunny. The potential for
pollen being released and entrained in the atmosphere is poor today because of
the prolonged period of low temperatures and mostly cloudy conditions. The dense air will move to the south. Any pollen that gets entrained within the
atmosphere will be moving at low levels where impaction should cause a majority
of it to be deposited relatively close to the source. Tomorrow, however will be clear and sunny
with warming temperatures in the 50s.
Tomorrow will have much better conditions for pollen release entrainment
