Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 435 AM EDT Mon Sep 02 2019 Valid 12Z Mon Sep 02 2019 - 12Z Wed Sep 04 2019 ...Extremely dangerous Hurricane Dorian is forecast to edge very slowly toward the central portions of the Florida east coast during the next couple of days... ...Thunderstorms could become severe across the northern Plains into the Great Lakes ahead of a cold front... ...Record-breaking heat today across portions of the central Rockies into the central High Plains... The upper-level pattern across the U.S. will continue to favor troughing over the eastern U.S. while a ridge will remain anchored over the West. Meanwhile, Hurricane Dorian has prompted Hurricane and Tropical Storm Warnings along portions of the Florida east coast. The forward motion of this powerful category-5 hurricane has slowed to a crawl as it moves right along the Grand Bahama Island with devastating impacts this Labor Day morning. The latest forecast from the National Hurricane Center indicates that Dorian will begin to turn toward the north-northwest just off the Florida east coast on Tuesday. However, a slight deviation to the left of this track could bring the core of Dorian over the Florida east coast. Please refer to the National Hurricane Center for the latest information regarding Dorian. Outside of Hurricane Dorian, the most active weather in the U.S. will be across the northern Plains into the Great Lakes as thunderstorms could become severe this evening into Tuesday ahead of an intensifying low pressure system and a cold front. Cooler air will then be ushered into these areas behind the cold front. Meanwhile, the heat over the Desert Southwest will be less intense today as the upper ridge weakens slightly. However, near-record to record-breaking temperatures are expected today across portions of the central High Plains where daytime temperatures are forecast to reach the upper 90s to near 100 degrees at some locations. Elsewhere, showers and thunderstorms are expected across much of the northeastern U.S. today as a wave of low pressure moves across the region. Clearing skies will follow on Tuesday. Meanwhile, relatively quiet weather will extend into much of the Deep South with typical summer heat and humidity as Hurricane Dorian looms just off the east coast of Florida with outer rainbands possibly starting to impact the coastal regions later today.
