Regional Weather: Thursday, January 2 TX/OK/AR: A cold front has moved across the area to the east leaving cold air to pull in behind it. Temperatures will be 5 to 10 degrees cooler today with winds being moderate to strong from the north to northwest. Skies will be clear as the cold, dry air moves into the region. In Texas temperatures will only reach the upper 40s in the north and upper 50s to the south with winds from the northwest in the 15 to 20 mile per hour range. Skies will be sunny and clear today and the humidity will remain low. Overnight the clear skies and dry conditions will result in low temperatures dropping below freezing with a freeze warning in effect across the Edwards Plateau and Hill country. Similar conditions will occur tomorrow with a 5 to 7 degree warming and wind strength diminishing. Winds will eventually turn from the northwest to the southwest during the day.

High temperatures today will range from the upper 30s to mid 40s with mostly sunny conditions and brisk winds from the northwest. Clearing skies and cold temperatures will drop conditions into the low to mid 20s overnight then a gradual warming will occur tomorrow with temperatures 5 to 7 degrees above todays..

OUTLOOK: *** Low Threat today*** unfavorable conditions for pollen release. Cold temperatures, clearing conditions but with a threat of lingering snow showers early today results in unfavorable conditions for pollen release. In addition the trajectories show poor characteristics for pollen entrainment and travel away from the source. With the lack of pollen to entrain there is a low threat to any downwind communities. Conditions will begin to improve tomorrow with warming temperatures but continued overall cold conditions.
