to clear in the afternoon. Lows tonight will range from the low 40s to the mid 50s across the area. Highs tomorrow
are expected to be in the low to mid 70s with partly cloudy skies.
Trajectory weather: The trajectories from the Edwards Plateau move to the north, northeast over central
Texas, Oklahoma and into Kansas on light to moderate winds. Across the Plateau this morning, temperatures will
be warm with afternoon highs in the mid to upper 60s. On the eastern and southern parts of the source area, skies
are overcast with fog and drizzle in some areas, while skies are clear on the central and western parts. Clearing
is expected this afternoon. Temperature will be moderate overnight tonight and warm up even further tomorrow.
OUTLOOK: *** Moderate to High Threat *** mixed conditions
for pollen release today and mixed conditions for entrainment and transport. Warm temperatures but high humidity
and overcast skies this morning on the eastern portion of the Plateau leads to only moderate conditions for pollen
release. Conditions for pollen release and transport on the western side of the plateau are favorable. Conditions
for pollen release may improve this afternoon across the region leading to high threat this afternoon and evening.
