Mountain Cedar Pollen Forecast

 

Date Issued: 1 February 2006



Mountain Cedar Location(s): Arbuckle Mountains, OK


Regional Weather: Wed. and Thurs., Feb 1 and 2. TX/OK: A weak cold front will move through western and central Oklahoma today dropping temperatures a few degrees from Tuesday. Daytime highs in Oklahoma on Wednesday will be in the mid 60s with southerly winds ahead of the front and in the low 60s with northerly winds in areas where the front has passed through. Skies in Oklahoma will be clear to partly cloudy. Highs in Texas today will range from the mid 60s to the mid 70s with variable winds, cloudy skies, and a chance of scattered showers. A second front will move through the region late tonight bringing north, northwest winds to the region tomorrow. Nighttime lows will range from the upper 30s to the upper 40s. Highs on Thursday with range from the 60s in Oklahoma to the mid 70s in Texas. Skies with be partly cloudy with variable winds.

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the northeast and then curve back around to the south as the winds shift following the frontal passage. Conditions at the source are warm with partly cloudy skies and moderate winds.The trajectories are not ideal for pollen transport. Thursday's trajectories move south through central and eastern Texas with characteristics that are not especially conducive to pollen transport.


OUTLOOK: *** Moderate to High risk *** Conditions are favorable for pollen release today and Thursday. Trajectories are not ideal for transport of the pollen so it is likely to remain close to the mountain cedar populations.

Trajectory Start (s) (shown by black star on map): Sulfur, OK.
