Austin

Moderate to High

San Antonio

Moderate to High

 

Date Issued: 14 January 2005


Mountain Cedar Location(s): Edwards Plateau, Texas


Regional Weather: Fri, Sat, and Sun, Jan 14 - 16. TX/OK: A cold high pressure system has moved in over the region, and reinforcing fronts will keep low temperatures in place for the next several days. Coldest conditions will be in northern Oklahoma. Daytime highs will be in the 20s and 30s in Oklahoma and the 50s in Texas. Night time lows will be in the teens and 20s in Oklahoma and the upper 20s and low 30s in Texas. Skies will be partly to mostly cloudy with low to moderate winds. Winds will be from the north in northern Oklahoma; wind direction will be variable in southern Oklahoma and Texas..


Trajectory weather: The air mass trajectories from the Edwards Plateau through the weekend show movement to the northwest then turn to the north and northeast. Day time temperatures at the source in the 50s with partly to mostly cloudy skies and variable winds. Night time temperatures will be in the 20s and 30s.


OUTLOOK: *** Moderate to High Threat *** Mixed conditions for pollen release. Day time temperatures are in the favorable range but night time temperatures will be cold across the Plateau. As a result pollen release will be delayed until warm-up occurs in the afternoon. Since the trees are nearing their peak release period significant amounts of pollen release might be expected in sheltered areas where localized temperatures may be greater. Individuals at greatest risk are those living northwest of the Edwards Plateau.


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