OUTLOOK: *** Moderate Threat *** We are in the peak of the pollen release season. Conditions are mixed for pollen release this afternoon. Temperatures will get very near the favorable range before topping out in the low 40's this afternoon. Winds are moderate. Humidities are high during the late morning hours. They will likely fall this afternoon. Though moisture values may not fall into the favorable range, they may drop rapidly enough to favor some release. Considering all these factors.... some pollen release is likely. Moderate Risk of exposure for residents of a broad area of central Arkansas today and tonight, stretching from the northwest to the southeast corners of the state. This includes the capital city of Little Rock. Low Risk of exposure for northeast and central LA on Tuesday. TK
