The cold front that brought destructive storms and tornadoes to the central Plains Thursday and Friday will move west-to-east from Kansas to the Ohio Valley.  This will push another round of strong, locally severe thunderstorms westward into the Ohio and Tennessee Valleys, and to eastern Oklahoma and southeastern Kansas.  The northern Plains from the eastern part of the Dakotas to southwestern Minnesota and northern Iowa may experience scattered storms consisting of damaging wind gusts, hail and blinding downpours.  Isolated, short-lived tornadoes could form.

Scattered severe thunderstorms could form from North Carolina to northern Oklahoma.  Tornadoes may form from super cells in the warmest air south of the Mason-Dixon Line.  Temperatures in the south-central states reach the 90s this weekend. West Texas will climb into the 100s.  El Paso could tie a record high both Saturday and Sunday.
West
Isolated, scattered showers and thunderstorms are expected along the Washington and Oregon coasts.  Storms may briefly turn severe with rainfall.  The Southwest will be rain free.  High temperatures will be near or below average along the West Coast but above average inland.  Afternoon temperatures will range from the 70s in Montana to between 100 and 110 degrees in the Desert Southwest.  A Red Flag Warning is in effect for south central Utah every afternoon and evening through Monday for gusty winds and low relative humidity.

Tropical Weather Outlook

Atlantic/Caribbean:
An area of low pressure associated with the remnants of former Eastern Pacific tropical storm Alma is centered over the Gulf of Honduras near the coast of northern Belize.  The low is moving
slowly westward .and the center is expected to move inland over the Yucatan peninsula during the next few hours. 
Satellite imagery and surface observations indicate this system is becoming better organized and a tropical depression could form if the center remains offshore this morning.  Even if no development occurs localized heavy rains and floods are possible during the next couple of days over portions of Honduras, El Salvador, Guatelamala, Belize, and southeastern Mexico. 

Eastern Pacific:
Tropical cyclone formation is not expected during the next 48 hours.

Western Pacific:
There is no activity affecting U.S. Territories. (NOAA, National Hurricane Center, Central Pacific Hurricane Center and the Joint Typhoon Warning Center)
