Weather Alerts For Troy, MI

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 PORTIONS OF THE MIDWEST SUMMARY Severe storms are possible this evening into the overnight hours across portions of the Midwest. Damaging winds will be the main hazard with this activity. Additional strong to severe storms may occur from western Nebraska into the Dakotas, and across Arizona. Midwest A bowing line of storms will continue to move east/southeast across northern OH the next few hours. Occasional damaging gusts will be possible with this activity before weakening after 04z as instability wanes across northeast OH/western PA. Model guidance continues to indicated additional convection will develop across portions of eastern IA/northern IL this evening. This activity may develop along residual outflow and a southward sagging surface front as a low-level jet increases over the next few hours. Thunderstorm clusters may grow into one or more MCSs moving east across northern IL into IN and perhaps southern Lower MI. Northern/Central Plains Damaging wind and hail will be possible with convection moving across western NE this evening. As ongoing storms track east/southeast, they will encounter richer low-level moisture and increasing instability. While stronger capping persisted with eastward extent, even elevated storms will pose a severe risk as they track across WW 0549. Severe potential is less certain with northward extent across the Dakotas. Low-level moisture will increase during the evening and overnight hours, but currently, instability remains weak and capping is strong. Isolated strong cells over northeast MT will continue to develop southeast into limited instability but stronger vertical shear. If storms can be maintained and additional development occurs later this evening/overnight isolated hail and strong wind gusts will be possible. AZ Similar to previous days, easterly midlevel flow will support convection moving westward off higher terrain and across the lower deserts within weak to moderate instability and steep low-level lapse rates. Strong to severe gusts will be possible with this activity.

Pollen Index: 8.7 Pollen Level: medium-high Predominant Pollen: Grass, Nettle and Plantain. The pollen levels for Monday will be falling in the moderate range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to rising humidity, strong winds and heavy rains in the morning which tend to wash pollen out of the air. This will improve your outlook if you have allergies and enjoy the out of doors.
