Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 330 PM EDT Sun Mar 08 2020 Valid 00Z Mon Mar 09 2020 - 00Z Wed Mar 11 2020 ...Rain for southern California late Monday into Tuesday... ...Heavy snow for parts of Northern Maine on Monday... ...Mild temperatures for the Northeast Monday... A frontal boundary over the Plains/Upper Midwest will continue to move southward and eastward to start the work week. A stationary boundary will extend across southern Canada into Maine. This will serve as a focus for rainfall over the middle Mississippi Valley late Sunday through Monday as an area of low pressure over Kansas moves northeastward to Iowa on Monday and then through Michigan on Tuesday. Light to modest rain should expand out of the southern Plains overnight with some embedded heavier elements. The eastern portion of the front across Maine will aide in producing light to moderate snow in the colder air and some mixed precipitation near the boundary with a south to southeasterly flow. Rainfall will push through the Ohio/Tennessee Valleys on Tuesday. Over California, a system over the Pacific Ocean will sink southward Monday and then eastward into Tuesday. Increasingly heavier rain (maybe with some thunder/lightning) is possible as the cold front approaches the coast, focused from about Point Conception southward through the Transverse and Peninsular Ranges. With areal amounts of one half to one inch in lower elevations to perhaps two to three inches in favored mountain areas, localized flash flooding is possible. WPC maintains a Slight Risk for Excessive Rainfall on Tuesday. Temperatures over the Lower 48 will mostly be above normal outside the Northwest on Monday and the Southwest on Tuesday. The Northeast will see much milder temperatures on Monday into the 60s/70s with southwesterly flow. These may approach record values in some locations.
