There is a Marginal 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 A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN/CENTRAL PLAINS INTO MISSOURI AND WESTERN ILLINOIS SUMMARY Isolated severe hail may occur this evening into the overnight hours across parts of the southern/central Plains into Missouri and western Illinois. Southern/Central Plains into Missouri and Western Illinois Ongoing convection across the lower OH Valley this morning is being aided by low-level warm advection, and is expected to remain sub-severe as it tracks eastward into a less unstable airmass. A belt of 45-55 kt mid-level southwesterly flow will be maintained today across parts of the southern/central Plains as a shortwave trough ejects eastward over this region though the period. A weak surface low over northeast NM and the OK/TX Panhandles this morning will gradually develop towards northwest TX by this evening as low-level moisture streams northward across TX/OK into the Ozarks and southern IL. A dryline is forecast to mix eastward across the southern High Plains by late this afternoon, intersecting the surface front in the northwest TX/southwest OK vicinity. Current expectations are for robust thunderstorm development to be suppressed across the southern/central Plains through much of the afternoon into early evening owing to the presence of a stout low-level inversion. One exception may be near the front/dryline intersection in southwest to central OK, where MLCIN should become minimal by peak afternoon heating. Here, some guidance suggests a low chance for a robust thunderstorm or two to develop and track northeastward along/near the I-44 corridor while posing an isolated hail threat. The Marginal Risk has been expanded slightly southward to account for this possibility. Otherwise, gradually increasing large-scale ascent preceding the shortwave trough and strengthening low-level warm/moist advection should encourage the development of elevated thunderstorms north of the front, mainly after 04/06Z. Around 1000-1500 J/kg of MUCAPE, steepened mid-level lapse rates, and strong effective bulk shear suggest that some of these cells may pose a threat for isolated severe hail as they spread from OK/KS into MO and western IL through early Wednesday morning.

Pollen Index: 9.6 Pollen Level: medium-high Predominant Pollen: Elm, Maple and Alder The quantity of pollen grains in the air for Tuesday will be rising in the high range. This results in part from rising temperatures, strong winds and lower relative humidity. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.
