The nation’s weather

Weather Underground Forecast for Tuesday, June 25, 2013.

Showers and thunderstorms will spread from the Midwest through the Northeast on Tuesday, while scattered showers will persist for the Pacific Northwest.  A low pressure system spinning offshore of the Pacific Northwest will continue pushing a cold front onshore. This front will bring more late season rain showers to the region from Washington through northern California and moving eastward into the Intermountain West throughout the day.  Expect strong winds and cooler temperatures to persist across the region with this system.

In the Central U.S., another low pressure system developing over the Plains will advance eastward over the Upper Midwest and Great Lakes on Tuesday. This system will produce more showers and thunderstorms from the Northern Plains through the Great Lakes, some of which may turn severe with strong winds and large hail.  Heavy rainfall will continue for these areas, thus, flooding will remain a concern for the Upper and Mid-Mississippi River Valley and surrounding tributaries.Â

In the East, a trough of low pressure that brought heavy rain with strong thunderstorms to the Midwest the past few days has makes its way over the Great Lakes and into the Northeast. This will kick up widespread scattered showers and thunderstorms from the Ohio River Valley through Maine.  There is a slight chance that some of these storms will turn severe with strong winds and large hail as the main threats.

Temperatures in the Lower 48 states Monday have ranged from a morning low of 32 degrees at West Yellowstone, Mont. to a high of 102 degrees at Lakehurst NAS, N.J.
