Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EDT Sat Aug 03 2019 Valid 00Z Sun Aug 04 2019 - 00Z Tue Aug 06 2019 ...Monsoonal moisture will bring daily chances for showers and thunderstorms across the Four Corners into the southern and central Rockies while increasing tropical moisture supports heavy rain across Florida and the Southeast coast... ...Excessive heat warnings and heat advisories are in effect for parts of the Southwest... Scattered showers and thunderstorms are likely into the beginning of the week for the Southeast, as a surface boundary over the Gulf coast, supported by an upper level trough over the Eastern half of the country, interacts with tropical moisture from the Gulf of Mexico. A surface trough oriented parallel to the Mid-Atlantic/southeast coast may produce locally heavy rainfall with amounts of up to 2 inches of rain possible for that region. A separate area, in northern Texas/eastern Oklahoma, is under a Slight Risk of Excessive Rainfall through Sunday morning. Flood watches and warnings are also in effect for parts of eastern Okalhoma. Elsewhere, the Storm Prediction Center issued Slight Risks of Severe Thunderstorms for parts of the Northern Plains and Upper Midwest due to the emergence of a Pacific frontal system tomorrow through Tuesday morning. Monsoonal moisture continues to stream northward into the Southern/Central Rockies, which will lead to showers and thunderstorms across the Four Corners Region for the next several days. Locally heavy to excessive rainfall should not be ruled out as a Slight Risk of Excessive Rainfall is in effect through Sunday morning for most of the Southern Rockies and part of southern Colorado. Excessive Heat Warnings are in effect for parts of the Southwest as an Upper level ridge remains over the western half of the country throughout the short range period. Some areas may reach or exceed 110 degrees. Temperatures will remain moderate in the east due to the aformentioned upper level troughing.
