Hurricane Dorian has induced Storm Surge, Hurricane Watch, and Tropical Storm Warnings are in effect for portions of the Florida East Coast. The latest forecast from the National Hurricane Center indicates that Dorian will move very slowly across northwestern Bahamas as a major hurricane late Sunday into Monday before turning northward near or just offshore of the Central Florida peninsula by Tuesday. Please refer to the National Hurricane Center for the latest information regarding Dorian. Above average to well-above-average temperatures are forecast to continue across much of the western U.S. into early next week under the warm high pressure ridge. Excessive heat warnings have been extended through today across portions of the southern California deserts, southern Nevada, including the Las Vegas metro, and western Arizona - where daytime temperatures are expected to climb into the triple digits once again. Near-record to record-breaking temperatures are expected Monday across portions of the central Rockies into the Great Basin. Daytime temperatures are forecast to reach the upper 90s to near 100 degrees across parts of the region. A cold front dropping southeast from the Pacific Northwest will support breezy conditions but little precipitation - generating elevated fire weather conditions from southwestern Montana and southern Idaho to northern Utah and southern Wyoming on Monday. Fall-like conditions will spread into the northern Plains by Tuesday morning behind the cold front. Following another day of scattered showers and thunderstorms, expect mostly dry conditions over the Central and Southern Plains today as the better chances for precipitation shift farther northeast through the Ohio Valley into the Northeast. Rain chances are expected to continue across the Northeast into Monday ahead of a cold front approaching from southeastern Canada. Meanwhile, as the aforementioned cold front over the West begins to move east of the Northern Rockies, showers and thunderstorms will become more likely across the Northern Plains and Upper Midwest on Labor Day where severe thunderstorms will become possible.
