A stalled out surface front along the Southeast Coast will be the focus for heavy rain and thunderstorms through Thursday afternoon. There are Slight Risks (at least 15%) of Excessive Rainfall leading to Flash Flooding over parts of eastern North Carolina and southeast Georgia/northern Florida today, where areas of surface low pressure along the stationary front may enhance rainfall rates/totals. The Storm Prediction Center has only a Marginal Risk (level 1/5) of Severe Thunderstorms along the Southeast Coast today. Rain showers should develop along the Mid-Atlantic and Northeast Coasts today along and ahead of a northern stream cold front. There's a Slight Risk of Excessive Rainfall for portions of southeastern Virginia into northeastern North Carolina on Thursday morning, right before the low pressure system and associated precipitation push off into the Atlantic. Showers continue along the Northeast Coast on Thursday with some potential snow showers developing over interior portions of New England. Coastal low development along the New England coast could also support some enhanced rain totals for southern New England, in particular, by Friday morning. Out West, a period of rainy/snowy weather will ensue across the Northwest today. Precipitation will spread across the Pacific Northwest this morning then into northern California and the interior Northwest this afternoon/evening. Moderate to heavy snow is possible over parts of the Cascades, Sierra Nevada and Northern Rockies; where between 1-2 feet of snow may accumulate by Friday morning. Elsewhere, troughing along the lee of the Rockies will promote southerly flow into the Great Plains beginning Thursday. This pattern will support above average temperatures from the Central/Southern Plains into the Midwest through the weekend.
