Hazardous Weather Outlook for Wednesday, July 1, 2015

by WeatherOps, on Jun 30, 2015 10:20:23 AM

Strong to severe thunderstorms are possible Wednesday for the Northeast, Missouri and Ohio River Valleys, and Northern High Plains. Heavy rainfall and flooding are possible for the Mississippi and Ohio Valleys.

Northeast: Low pressure is forecast to lift into eastern Canada on Wednesday while a trailing cold front moves into the Northeast. The front, combined with a strong upper level disturbance, should help initiate thunderstorms across the region during the afternoon hours. Some strong to perhaps a few severe storms containing gusty winds will be possible.

Mississippi & Ohio Valleys: A low pressure area is forecast to move into the Great Plains on Wednesday, allowing for low level moisture to increase across central portions of the United States. Scattered to numerous thunderstorms will likely develop across the area, including potential complexes of storms. Strong to even severe thunderstorms will be possible, with damaging winds and hail the main threats.

Northern High Plains: A another small trough will progress through the high plains on Wednesday, allowing for strong ascent in the region again. Numerous thunderstorms will be possible, with rotating updrafts producing damaging wind gusts and large hail in some instances, but a widespread severe threat is currently not forecast.

Mississippi & Ohio Valleys: In addition to the potential severe threat, heavy rain is anticipated across the area Wednesday afternoon/evening and into the overnight hours. Numerous thunderstorms, including complexes of storms, may produce rainfall amounts in excess of 2 inches across the area. This could lead to an increased flooding threat, especially for low-lying locations.
