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 UPPER MISSISSIPPI RIVER VALLEY THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS FAR EASTERN KANSAS AND FAR WESTERN MISSOURI SUMMARY Severe thunderstorms will continue across the Upper Mississippi Valley and Great Lakes region with potential for large to very large hail, damaging wind, and tornadoes, through the overnight hours. A more focused risk for severe storms will continue through late evening across the southern to central Plains. Synopsis Late-evening surface analysis reveals a slow-moving surface low over eastern NE with a warm frontal zone draped eastward into southern MN and central WI. Scattered strong to severe thunderstorms are ongoing along the frontal zone as of 01 UTC and will likely continue through much of the overnight hours across the upper MS Valley and the Midwest. Further south, several attempts at convective initiation have been noted along a dryline draped from eastern NE southward into KS, OK, and TX. Although additional attempts at thunderstorm development are possible over the next few hours, the primary severe risk will be focused across the Kansas City metro area where a cluster of supercells has emerged. Upper MS Valley/Midwest Scattered supercells are ongoing across southern MN and into central WI along and north of the surface warm front. A tornado and significant (2+ inch) hail threat will likely persist for the next couple of hours, but the expectation is for increased storm clustering and upscale growth through the overnight hours. The developing MCS will likely spread east/southeast into southern WI and possibly northern IL prior to 12 UTC Tuesday with an attendant risk for severe winds. Eastern Kansas/western Missouri A cluster of supercells has emerged across eastern KS over the past few hours and will likely continue to spread east into western MO through late evening. Given very favorable thermodynamic and kinematics noted in the 00z TOP sounding, this activity will likely continue to pose a threat for very large hail and tornadoes. 15% hail and 5% tornado probabilities have been introduced to account for this localized threat. Southern Plains GOES imagery over the past few hours has shown several attempts at convective initiation across OK and TX; however, most of these attempts have failed due to very meager/localized ascent along the dryline. While one strong storm is noted across northwest TX, the potential for new storm development should wane through the evening given residual inhibition noted in 00z soundings and as nocturnal cooling begins to diminish the dryline circulation. Because of this, opted to remove 15% risk probabilities, but maintain some risk probabilities given the ongoing convection and otherwise very favorable convective environment.

Pollen Index: 11.3 Pollen Level: high Predominant Pollen: Maple, Cedar/Juniper and Alder. Concentration of pollen grains in the air for Tuesday will be falling but will remain in the very high range. This decrease is due to rising humidity, weakening winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.
