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 AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF KANSAS...OKLAHOMA AND WESTERN NORTH TEXAS THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE OHIO VALLEY AND MID ATLANTIC SUMMARY Severe thunderstorms with damaging wind gusts, large hail and a few tornadoes are likely across the southern and central Plains this afternoon and evening. Strong to severe storms are also possible from parts of the Ohio Valley, central Appalachians and Mid-Atlantic. 20z Update OK/KS/MO Observational trends and model guidance continue to show rapid destabilization taking place this afternoon as a warm front gradually lifts northward across OK into southeastern KS and southwestern MO. Large-scale ascent is forecast to increase rapidly tonight as the primary upper trough over the Four Corners ejects eastward, aiding in storm development along a broad area of the front. Semi-discrete supercells and clusters are possible tonight before upscale growth takes place after 00z. The strong synoptic ascent should favor a rapid strengthening of low-level flow and shear. This would support a risk for damaging gusts and some tornadoes with remaining supercells or linear segments. Expand the 5% tornado and 15% wind areas farther east into MO where CAM guidance shows storm persisting overnight. Farther southwest, no significant changes were made to the prior outlook. Scattered semi-discrete thunderstorm development remains likely along the dryline/front intersection across west/southwestern OK into western north TX this afternoon amid filtered heating of a moistening air mass. Initial supercells will pose risk for large hail and a couple tornadoes. The damaging wind threat (and possible some QLCS tornado risk) will likely increase after dark as storms congeal and spread northeastward beneath an intensifying 40-50 kt low-level jet. OH Valley and Mid Atlantic Elsewhere, scattered thunderstorms are ongoing and expected to gradually increase in coverage through this evening along a frontal zone across the OH Valley into the Mid Atlantic. South of the front, moderate buoyancy and deep-layer shear will support some storm organization with supercells or organized clusters from northeast KY into southern OH and parts of WV/VA. Damaging gusts, and perhaps some hail are possible with the stronger storms.

Pollen Index: 9.7 Pollen Level: high Predominant Pollen: Maple and Cedar/Juniper. The amount of pollen in the air for Thursday will be greater than today's levels and extend further into the very high range. Since the weather has a major influence on pollen dispersal, this increase is due in part to strong winds and decreasing humidity.
