Closest strike: 4.31 miles Stay Alert! Remain in a safe area until there has been no lightning within 10 miles of this location for 30 minutes. Please be aware that lightning activity can remain high even when a storm is moving away from your location. Even if rain has stopped, do not leave your safe area until WeatherBug indicates that lightning is more than 10 miles away from this selected location. IF OUTDOORS Avoid water, high ground, and open spaces. Avoid all metal objects including electric wires, fences, and machinery. Find a safe area in a building or in a fully enclosed vehicle with the windows completely shut. Unsafe places include underneath canopies, small picnic or rain shelters, convertibles, or near trees. IF INDOORS Avoid water and stay away from doors and windows. Avoid using a hard line telephone. Take off headphones. Turn off, unplug, and stay away from appliances, computers, power tools, and TV sets. Lightning may strike exterior electric and phone lines, inducing shocks to inside equipment.

There is a Marginal Severe Storm Risk for your location.

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: 8.9 Pollen Level: medium-high Predominant Pollen: Cedar/Juniper, Birch and Maple. The quantity of pollen grains in the air for Tuesday will be falling but will remain in the high range. This decrease is due to rising humidity, relatively calmer winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.
