Damaging winds, hail, and a couple of tornadoes remain possible through the overnight. 01Z Update Thunderstorms continue to develop along and ahead of an advancing cold front this evening. These storms should continue to increase in number, growing upscale into an extensive linear MCS from Northwest Texas northeastward into southern Iowa. Despite nocturnal stabilization of the boundary layer, forcing along the cold front, MUCAPE between 1000-2000 J/kg, and sufficient vertical shear should support a continued hail and wind threat into the overnight hours, especially across the southern portion of this area where updrafts appear to be more robust than areas farther north. Given the moist low-levels and a modest uptick in the low-level jet, a couple of tornadoes may still occur as well. Additional thunderstorms have developed eastward along the warm front draped across southern Iowa east across Illinois, Indiana, Ohio, and Pennsylvania. MUCAPE and vertical shear decrease with eastward extent along the warm front, organized thunderstorms within the frontal zone should support an localized hail and wind threat for a few more hours. A tornado or two could also be realized with any discrete/semi-discrete cell that can increase its resonance time in the frontal zone, especially across central Illinois where better instability and vertical shear exist.

Pollen Index: 11.6 Pollen Level: high Predominant Pollen: Maple, Cedar/Juniper and Elm. The amount of pollen in the air for Saturday will be falling in the moderate range.

With this amount of reduction in pollen levels, tomorrow should be better for allergy sufferers.
