There is a Enhanced 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 ACROSS PARTS OF THE MIDWEST/SOUTHERN GREAT LAKES AND SOUTHERN/CENTRAL PLAINS THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHEAST SUMMARY Severe thunderstorms are expected this afternoon through tonight from the southern Plains into the Midwest. Large to giant hail, several tornadoes (some strong), and swaths of severe/damaging gusts are all likely, particularly from Iowa into the southern Great Lakes. 20Z Update A complex yet active severe weather day remains in the forecast for portions of the Midwest-OH Valley into the Southern Plains this afternoon into early tonight. While several lines were slightly adjusted to account for the latest guidance consensus, the following substantial changes and/or decisions were made: 1.) 30 percent wind probabilities were expanded southwestward into southwest and central OK to account for the possibility of more rapid upscale growth into one or more wind-producing MCSs or linear segments. 2.) Category 1/Marginal Risk probabilities for severe wind and hail were expanded west-southwest into NE along a frontal boundary to account for two possible scenarios. First, an isolated strong storm may develop within the next few hours along the boundary as a consequence of strong diurnal heating. Second, late tonight, there is low potential for gravity-wave associated convection on the immediate cool side of the frontal boundary, atop a stable boundary layer. 3.) Confidence is still too low for supercells across the Midwest to remain discrete for long periods of time, which would warrant a Categorical Moderate risk upgrade. Nonetheless, should a dominant supercell become sustained and discrete for at least a few hours, especially along the warm front over northeast IA into southern WI, a sustained and intense tornado will be possible. The rest of the forecast (see below) remains on track.

Pollen Index: 9.9 Pollen Level: high Predominant Pollen: Maple, Elm and Cedar/Juniper. Based on past pollen counts and expected weather conditions, pollen levels for Wednesday will be falling in the moderate range. This relief in pollen levels is caused in part by rising humidity, weakening winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. This reduction in pollen levels should be a relief to allergy sufferers.
