There is a Slight Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER MUCH OF ILLINOIS INTO NORTHEAST MISSOURI...AND OVER NORTHERN OKLAHOMA SUMMARY Damaging storms producing wind, hail and isolated tornadoes remain possible this evening from Illinois into Oklahoma. WI/MI into IL and MO Supercells have largely merged into a broken line of assorted bows from far southeast WI across much of northern into western IL and trailing into northeast MO. The 00Z ILX sounding shows steep lapse rates aloft and large deep-layer shear, as well as veering winds with height. Low-level SRH will remain favorable for rotation to develop at least briefly anywhere within the line, with damaging winds the most likely threat. Storms have recently become better organized over central MO, and this activity may affect the St. Louis area later tonight. For lower MI into northern IN, the organized line of storms to the west along with a 60 kt low-level jet suggest at least isolated severe gusts may occur overnight despite lesser instability. For more information about Illinois, see mesoscale discussion 484. OK...Southeast KS...southwest MO...northwest AR Scattered severe cells persist near and north of the cold front across much of northern OK and extending into southeast KS. Although the undercutting cold air will likely mitigate wind potential, steep lapse rates aloft along with ample deep-layer shear will continue to favor hail. Storm coverage may be more isolated into southwest OK later tonight, but the environment remains quite favorable for large hail. One corridor for possible damaging wind or even a tornado is over northeast OK into southwest MO. Here, the front is not surging as fast, and storms over Osage county are already oriented more favorably N-S relative to the deep-layer shear. A southwest low-level jet near 50 kt will further support low-level rotation.

Pollen Index: 11.5 Pollen Level: high Predominant Pollen: Hickory/Pecan, Oak and Sycamore. The amount of pollen in the air for Saturday will be falling but will remain in the high range. This change results in part from falling temperatures and expected precipitation in the morning and evening which tends to wash pollen out of the air. With this amount of reduction in pollen levels, tomorrow should be better for allergy sufferers.
