ALT Confidence is high that a low pressure system will develop across the Ohio Valley Wednesday and then shift off the Mid-Atlantic coast while strengthening Friday. Trends in the model guidance suggest a slightly faster system with less overall precipitation. The threat for at least some impactful high elevation snow remains, but the risk has decreased in lower elevations. The exact placement of the storm — small shifts in the track will greatly change impacts. The amount of snow that may occur, and what impacts will result from this snow. The impacts to coastal regions due to gusty winds and onshore flow. Confidence in storm development remains high, but details will continue to adjust. The threat for low elevation snow has decreased, but high elevation snow and coastal impacts are likely. Keep up to date with the latest at weather.gov

ALT WHAT WE KNOW: A wave of low pressure is likely to develop across the Ohio Valley late Wednesday and then track eastward to off the Mid-Atlantic coast Friday while strengthening. This low pressure will cause expanding precipitation, with rain and high elevation snowfall possible. Much cooler than normal temperatures will accompany this system Friday and through next weekend. WHAT WE DON’T KNOW: The exact placement of the storm — small shifts in the track will greatly change impacts. The amount of snow that may occur, and whether lower elevations will receive any accumulation. The impacts to coastal regions due to gusty winds and onshore flow. BOTTOM LINE: Confidence in storm development is higher than confidence in specific impacts. Forecast details will change over the next several days. Keep up to date with the latest at weather.gov

ALT Graphic explaining the new “Particularly Dangerous Situation” (PDS) wording that may appear in Blizzard Warnings and Ice Storm Warnings starting this winter. The designation indicates high confidence in a rare, extreme, potentially historic winter weather event posing an exceptional threat. A yellow warning triangle emphasizes the message to stay off the roads and exercise extreme caution. NOAA and National Weather Service logos appear at the bottom.

ALT NWS Peachtree City infographic titled "1 in 1000 Year Rainfall Event". A radar map shows an intense bullseye over north Georgia (centered near Blue Ridge) with 7 to 11+ inches of rain. A table lists 24-hour rainfall reports: 2 NW Blue Ridge: 11.19" (UGA) Higdon: 9.08" (HADS) 2 S Mineral Bluff: 8.40" (HADS) 4 N Mineral Bluff: 7.57" (COCORAHS) 1 N Colwell: 6.38" (COCORAHS) 2 W Nottely Dam: 6.24" (APRSWXNET/CWOP) Nottely Dam to Young Harris: 3.41"–4.58" Text notes: Per NOAA Atlas 14, the 12-hour total of 11.19" and 6-hour total of 10.28" exceed a 1-in-1,000-year rainfall event (the maximum extrapolation available). It notes rainfall event rates differ from flooding interval rates, which USGS will survey

ALT Days 1-3 Quantitative Precipitation Forecast (QPF) graphic valid Friday, November 6th to Monday, November 9th. After a long dry spell, rain finally returns in parts of the East Coast and Mid-Atlantic as a cold front moves eastward into the Atlantic.

In the Northwest, a series of storm systems will bring rainfall and high elevation snow over the next few days, while southern Texas sees heavy rainfall and thunderstorms on Sunday.
