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 SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE LOWER GREAT LAKES/OHIO VALLEY SUMMARY Severe thunderstorms capable of producing scattered damaging winds and perhaps a tornado or two appear possible across parts of the Lower Great Lakes and middle/upper Ohio River Valley region this afternoon through early evening. Other more isolated strong to severe thunderstorms may occur across parts of the the Tennessee Valley, Lower Mississippi Valley, and central/east/south Texas. Midwest/Lower Michigan to Pennsylvania and Western New York An upper trough over the Upper Midwest late this morning will continue moving northeastward toward the upper Great Lakes through tonight. Strengthening deep-layer southwesterlies (with 50+ kt present at 700 mb) will overspread IN/MI toward the Lower Great Lakes atop a gradually moistening/heating boundary layer along and north of the Ohio River. This will occur ahead of a surface low over WI/MI and convectively reinforced/southeastward-developing cold front that will impact parts of the Midwest/OH Valley this afternoon. Recent visible satellite trends showing clearing across much of OH into northwest PA suggest sufficient heating and modest diurnal destabilization will support at least some severe potential regionally as thunderstorms redevelop and intensify this afternoon along/ahead of the cold front. Given steepening low-lapse rates and enhanced low/mid-level southwesterly flow, scattered severe/damaging winds should be the main threat. But, there may also be some potential for a tornado or two as well, mainly in vicinity of the triple point/nearby warm front that will extend eastward into central PA. Overall updraft intensities should decrease by mid to late evening, owing to stabilizing/nocturnal boundary-layer influences, and the primary upper trough/low moving northeastward away from the region. Tennessee Valley into the Lower Mississippi Valley/Texas Showers and occasional thunderstorms remain extensive this morning from the Mid-South southwestward into northeast TX, as a surface cold front continues to progress southeastward across these areas. Even with considerable cloud cover and poor lapse rates aloft ahead of this ongoing activity, multiple corridors of reinvigorated convective clusters should develop this afternoon where some cloud breaks/filtered heating can occur. Downbursts with locally damaging winds should be the primary severe hazard, but this threat is expected to remain relatively isolated given lessening deep-layer shear with southward extent into the lower MS Valley/TX.

Pollen Index: 11.1 Pollen Level: high Predominant Pollen: Maple, Poplar/Aspen/Cottonwood and Cedar/Juniper. Concentration of pollen grains in the air for Sunday will be falling in the moderate range. This forecast of lower pollen concentration is based on falling temperatures and heavy rains in the morning and evening which tend to wash pollen out of the air. That's good news for allergy sufferers.
