Tropical Storm Debby is spinning in the Gulf of Mexico. On Sunday, this system will produce more heavy rains and strong thunderstorms over Florida, western Cuba, and the Gulf Coast. Tropical Storm Warnings have been issued for parts of Louisiana. However, intensification is not anticipated as this system moves northwestward towards eastern Texas and remains just south of the Gulf Coast. The system is expected to maintain tropical storm strength on Sunday with winds between 39 and 73 mph (33 and 64 knots). As the system pushes warm and humid air onshore, it will trigger scattered showers and thunderstorms over the region Sunday. Meanwhile to the north, a low pressure trough moving through the Great Lakes will push a cold front through the Midwest. This will kick up shower and thunderstorm activity over the Great Lakes and Ohio River Valley. There is a slight chance that these storms will turn severe with damaging wind gusts and large hail. Most of these areas are expected to get about 1 inch of rain, while areas of severe thunderstorm development could see up to 2 inches of new rainfall. Out West, a low pressure system off the West Coast will continue pushing moisture onshore. This will support more widespread rain showers over Washington, Oregon, and far northern California. Temperatures will remain seasonably cool for the West Coast. However in the Southwest, high pressure dominates from the Southwest through the Great Basin and Central Rockies, which keeps fire danger high across the region. Temperatures in the Lower 48 states Saturday have ranged from a morning low of 30 degrees at Bryce Canyon, Utah to a high of 105 degrees at Lamar, Colo.
