Today’s Severe Weather Outlook
Tuesday, June 18, 2013
Forecaster: Ryan Stinnett
Another active day for severe weather is expected across several areas of the country today. The Storm Prediction Center in Norman, Oklahoma has issued 4 slight risks for severe weather today. These risks are for portions of the Southeast Coast, the Ohio Valley, the western Plains and areas up around the Bitterroot Range in Montana and Idaho.
Several upper-level and surface disturbances will be impacting the risk areas today with the threat of severe weather.
Along the coast of the Carolinas, a warm, moist air mass will allow thunderstorms to develop later this afternoon as an upper-level feature moves across this region. Along with the upper-level feature, a surface boundary will provide additional uplift and after daytime heating, allowing storms will develop. The greatest threat with these storms will be hail and damaging winds.
In the Ohio Valley, there are some ongoing showers and storms this morning and these storms are expected to intensify after daytime heating and as uplift increases across the region later today. Hail and damaging winds will be the main threat here too.
For the western Plains and northern Rockies, moisture levels are sufficient and diurnal temperatures will help lead to increases in instability. Upslope flow across the areas will provide just enough uplift to allow for showers and thunderstorms to develop later this afternoon and last into the overnight hours. Hail and damaging winds will be of be the greatest threats, but a few isolated tornadoes will be possible as well.
We will be watching areas along the Gulf Coast today too. Currently, this area is outlined in the general thunderstorms category. Widespread showers and thunderstorms are ongoing this morning, and as the day continues, additional activity is expected to develop.
For Wednesday and Thursday, the threat for severe weather appears to shift north. The SPC has slight risks issued both days along the Canadian boarder from Montana east through North Dakota and Minnesota.
