Severe Storm Risk - Savannah, GA

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 SOUTHEAST AND MONTANA SUMMARY Thunderstorms with isolated strong to severe winds may occur this afternoon and evening across parts of the Southeast and Montana. Southeast A very weak mid-level trough will persist over the Deep South and Carolinas today, with modest westerly flow. Although rich low-level moisture remains present across these areas, multiple days of convective overturning has resulted in rather poor lapse rates aloft. This, along with persistent cloudiness, should limit to some degree how much instability will develop this afternoon with filtered daytime heating. Deep-layer shear will also remain weak, and thunderstorms should generally be disorganized. Some loose clustering may eventually occur with convection spreading eastward from the central Gulf Coast towards the FL Peninsula, where low-level lapse rates should become steepened by peak afternoon heating. Isolated damaging winds appear possible with the strongest cores from parts of FL into eastern GA and SC ahead of the weak mid-level trough. Montana Mid/upper-level ridging will extend from the southern/central Rockies to the northern Plains/Upper Midwest through the period, with a belt of enhanced southwesterly mid-level flow over western/central MT. High-based thunderstorms may develop this afternoon across parts of southwest into central MT amid a deeply mixed boundary layer. While low-level moisture and related instability are both expected to remain limited, some risk for occasional strong to severe gusts may accompany this convection as it spreads northward through the early evening before weakening. Arizona Showers and isolated thunderstorms are still ongoing this morning across parts of southern AZ. While mid-level east-southeasterly flow will persist today across much of AZ on the southern periphery of prominent upper ridging, it remains unclear how much destabilization will occur in the wake of this morning's convection. Whether convection will be able to spread westward off the higher terrain of southeast AZ and the Mogollon Rim is also uncertain. Have therefore not included low severe wind probabilities with this update.
