Date Issued: 31 December 2004
Mountain Cedar Location(s): Edwards Plateau, Texas
Regional Weather: Fri.,
Sat., and Sun, Dec 31, Jan 1 and 2. TX/OK: Above normal temperatures continue over the holiday weekend.
Day time highs will be spring-like in the 60s and 70s with high humidity throughout the region. Patchy early morning
fog in some areas this morning will lift by mid-day. Night time lows will be in the 50s. Winds will be southerly
for most of the weekend and rain chances will increase as an upper level disturbance approaches from the southwest.
Scattered rain and thunderstorms are likely through the area on Saturday, Sunday, and Monday.
Trajectory weather: The air mass trajectories from the
Edwards Plateau move to the north. Trajectories show mixed conditions that are less than ideal for entrainment
and travel of pollen downwind. At the source, conditions for pollen release should be favorable this afternoon
after patchy fog lifts.Temperatures are in the favorable range throughout the Plateau. Overnight temperatures will
be in the 50s tonight with mild temperatures continuing all weekend. However, scattered rain and thunderstorms
this weekend may reduce pollen dispersal.
OUTLOOK: *** Moderate to High Threat *** Favorable conditions for pollen release on Friday
once patchy fog lifts and humidities decrease. Mixed conditions for pollen release on Saturday and Sunday with
the chance of scattered showers and thunderstroms in the region. High threat continues in areas that remain dry.
