Mountain Cedar location(s): Arbuckle Mountains, OK
Regional weather: Tuesday,
January 27 – TX/OK: Across the region today conditions will be sunny and
warm. The region will be under clear
skies and sunny conditions this morning.
However, in the far southwestern area of the Edwards Plateau partly
cloudy conditions will begin the day but will soon clear. Temperatures will be warm today with the
central portion of the forecast areas in the mid- to upper 70s. To the north in southern Oklahoma temperatures
will be in the mid- to lower 70s as well.
Winds will be light over the
region to begin with and a mixed pattern that will shift tonight to a
dominantly south to southwesterly source.
Overnight conditions will only cool into the mid to upper 40s. Winds from the south will be building
overnight. Tomorrow skies will be mostly
sunny to sunny. Temperatures will build
once again into the 70s with a near repeat of today. Winds will continue to strengthen coming from
the south at moderate conditions.
Tonight temperatures will remain mild with lows mostly in the upper 40s
across the Edwards Plateau and the border region from Dallas into southern
Oklahoma. The edge communities surrounding
the Edwards Plateau will be mild with low temperatures staying in the mid- to
Air mass trajectories over southern
Oklahoma will be light and somewhat variable this morning. This afternoon the southern breeze will begin
to establish themselves across the region and will build into moderate to
strong conditions tomorrow. Winds will
move entrained material towards the north beginning tonight on increasing southerly
winds. Temperatures will be warm both
today and tomorrow with highs expected in the 70’s. Conditions are very good for pollen release
across the region today and tomorrow. In
additions the air is becoming more buoyant over the forecast period. Long distance travel and dispersal at some
distance is expected today and tomorrow.
With the southerly winds the most affected areas will be north of the
OUTLOOK: *** Severe Threat Today and Severe Threat Tomorrow*** Today and tomorrow conditions
will be very good for pollen dispersal.
Entrainment and downwind travel will occur, with the winds light to
begin with but building over the forecast period. High temperatures will climb in to the 70s
today and tomorrow. Winds at the surface will be somewhat mixed to begin with,
but will build from the southwest this afternoon, tonight and tomorrow. The trajectories move to the north and the
atmosphere is becoming lighter and more buoyant and thus the trajectories will have
significant pollen entrained within the atmosphere. These conditions will bring significant
concentrations into the atmosphere over the region. The communities of central to north Texas, as
well as Oklahoma will see some of their highest pollen levels this season.
