Low pressure area that was developing in Texas yesterday will move to the east, kicking off showers or thunderstorms in eastern sections of Texas as it goes. Cloudy this morning in OK and northern and eastern TX with fog, drizzle (TX), or freezing drizzle (OK). Highs in the 30's and 40's north, 60's and 70's most of TX. Winds shifting to the north with falling temperatures most areas this afternoon. Chance of showers eastern and southern sections this afternoon and evening before the front passes. Colder tonight with lows in the 10's and 20's north and west, 30's and 40's south and east. Becoming partly cloudy to sunny on Saturday and cold, highs in the 30's OK, 40's and 50's TX.

OUTLOOK: *** Low Threat *** Conditions unfavorable for pollen release today and Saturday. Temperatures are much colder than the favorable range. Humidities are high today and there's a chance of precipitation. Continued cold on Saturday, when the trajectory goes slowly south during the day and then turns northward. Pollen transport from this source is unlikely today and Saturday. TK
