Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE LOWER GREAT LAKES/OHIO VALLEY SUMMARY Severe storms capable of damaging winds and a tornado risk are expected across parts of the Lower Great Lakes and middle/upper Ohio River Valley, mainly this afternoon through early evening. Other more isolated severe storms may occur across the Tennessee Valley, Lower Mississippi Valley, and eastern part of Texas. Ohio/Eastern Indiana/Lower Michigan to Pennsylvania/New York A shortwave trough over the Upper Midwest early today will continue northeastward toward the upper Great Lakes through tonight. Cyclonically influenced strengthening deep-layer southwesterlies (50+ kt 700 mb) will overspread Indiana/Michigan toward the Lower Great Lakes, atop a steadily moistening/heating warm-sector boundary layer along and north of the Ohio River. This will be ahead of a surface low and cold front, that is considerably augmented by generally weakening thunderstorms and prevalent lingering clouds/outflows through the pre-dawn hours. These residual factors cast uncertainty regarding the magnitude of today's overall potential, but a formidable flow field and guidance-advertised heating/steady diurnal destabilization will still be supportive of at least some severe potential regionally as storms redevelop and intensify this afternoon. This includes damaging wind potential, particularly given the magnitude of low/mid-tropospheric winds and boundary layer mixing, with some tornado threat as well, mainly in vicinity of the triple point/nearby warm front. Overall storm intensities should decrease by mid/late evening, owing to nocturnal boundary-layer influences and the primary upper-level system spreading away from the region. Tennessee Valley/Lower Mississippi Valley/Texas While diminishing in intensity overnight, showers/thunderstorms remain extensive and prevalent from the Mid-South/Ozarks southwestward into North Texas, as a synoptic cold front otherwise continues to progress southeastward across these regions. While details are complexified by considerable cloud cover and lingering storms, multiple corridors of reinvigorating storms should materialize this afternoon where more appreciable cloud breaks/heating occur. Downbursts/locally damaging winds will be the primary severe hazard, but this is currently expected to be on a relatively isolated/episodic basis.

Pollen Index: 8.8 Pollen Level: medium-high Predominant Pollen: Cedar/Juniper, Elm and Maple. The quantity of pollen grains in the air for Sunday will be falling but will remain in the high range. This lowering of pollen concentrations is a result of falling temperatures and expected precipitation in the morning and evening which tends to wash pollen out of the air.
