Date Issued: 6 January 1998

Mountain Cedar location(s): Edwards Plateau, Texas

Regional weather: Wednesday, January 6 - TX/OK: Dry for today. Mostly cloudy early for eastern sections of both states. In the afternoon, sunny to partly cloudy region-wide. Highs in the 50's and 60's with some 70's south TX. Lows tonight in the 20's and 30's, with some 40's and 50's south and east TX. Cold front dropping down from the north will bring some changes to OK on Thursday.

Trajectory weather: Mostly sunny west.....cloudy with fog this morning east, then mostly sunny in the afternoon. High in the mid-to-upper 60's. Fair tonight..... clouds and patchy fog developing along the Austin trajectory.....low in the upper 30's. Variably to mostly cloudy on Thursday, high in the 60's.

Trajectory confidence: High

OUTLOOK: *** Moderate Threat *** Mixed conditions for pollen release today, tending towards the favorable side for the afternoon hours. Humid, foggy conditions towards the central and eastern sections of the Plateau are combining with calm to light winds to damper the pollen release situation as compared to Tuesday. Some release will occur, most likely during the afternoon hours and most likely from the western sections of the Plateau. Airborne pollen won't move very far during the next 24 hours. Persons most likely to be affected are those living in south-central, central, and north-central Texas. TK
