Date Issued: 09 December 2002
Mountain Cedar location(s): Ozark Mountains, AR/MO
Regional weather: Monday, December 9 TX/OK/AR: Cloudy and rainy weather will greet most of the
region today. A weather system is currently centered over the state
and will bring wet weather to the region today then move towards the east to northeast over night.
Heavy rainfall is expected over regions of Texas and into
Oklahoma throughout the day.
Winds will be light to the north and moderate in the south. Temperatures will remain in the upper 40s south
and low 40s to upper 30s to the north. Lows overnight on Monday will be in the low 30s to the north and upper
30s to the south with calm winds throughout the region. On Tuesday,
cloudy conditions will prevail with heightened humidity throughout the region.
Temperatures will begin to warm reaching the mid-to upper 50s to the south and mid-40s to the north. Winds
in this region will remain moderate to light out of the southwest in the western portions of the area and from
the north to northwest along the eastern sections of the Edwards Plateau.
In Oklahoma winds will be from the south to southeast and light. Partly cloudy conditions with increasing sun breaks and clearing is expected
late Tuesday afternoon and into Tuesday evening.
Trajectory weather: The air mass trajectories from the Ozark Mountains initially
move to the west then rapidly shift due north. The regional weather
system in Texas will be moving to the east through Arkansas
during the evening and into Tuesday, bringing an increasing chance of rain to the area.
Temperatures will remain cold with highs only in the 30s today and upper 30s tomorrow.
Skies will be partly cloudy to mostly cloudy throughout the forecast period. Light to moderate winds will
be out of the east/southeast today and tomorrow. Cloud breaks and sunnier skies will begin tomorrow with
temperatures beginning to warm.
OUTLOOK: ***Low threat today *** unfavorable conditions for pollen release today. Conditions
in the Ozark Mountains are unfavorable for pollen release today with low temperatures and
the potential for precipitation. Field observations have yet to see
trees actively pollinating therefore we feel the risk for pollen release is unfavorable and there is a low threat
for the region.
Trajectory Start(s) (shown by black star on map): Oak Grove,
