Mountain Cedar Pollen Forecast

 

Date Issued: 3 February 2006

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Fri, Sat, and Sun, Feb 3-5. TX/OK: A weak cold front moves across the region today with moderate to gusty northerly winds. Daytime highs in Oklahoma will range from the upper 50s to low 60s and in Texas from the mid 60s to the low 70s. Skies will be partly to mostly cloudy with a chance of scattered showers in north central Texas. Lows tonight will be in the 30s. Winds will return to a southerly flow on Saturday afternoon and become strong on Sunday ahead of the next cold front which will move into the area on Monday. Highs on Saturday and Sunday will be in the mid to upper 50s in Oklahoma with partly cloudy skies and in the upper 60s to low 70s in Texas with clear skies. A red flag fire alert is likely to be in effect in several counties over the weekend. The cold front moving into the area on Monday will probably drop temperature to seasonal levels or even below normal temperatures.


Trajectory weather: The air mass trajectories from the Edwards Plateau move to the south today and curve back around once the winds shift back to a southerly flow. Each of the trajectories shows characteristics associated with the cold air and move primarily at ground level. Trajectories on Saturday begin moving to the east then turn north over central Texas and Oklahoma. Sunday's trajectories move to the northeast over Texas. Conditions at the source areas will be warm with partly cloudy skies and moderate to strong winds.

OUTLOOK: *** High risk *** Favorable conditions for pollen release. 

Trajectory Start (s) (shown by * on map): Austin, TX; Junction, TX; San Angelo, TX.
