Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 410 AM EDT Thu Oct 08 2020 Valid 12Z Thu Oct 08 2020 - 12Z Sat Oct 10 2020 ...Hurricane, Storm Surge and Tropical Storm warnings are now in effect as Hurricane Delta looks to approach the northern Gulf coast and a make a landfall across south-central Louisiana on Friday... ...Very heavy rainfall will impact areas of the central Gulf Coast and Lower Mississippi Valley through Friday and Saturday with rain gradually overspreading the Ohio Valley and Mid-Atlantic through the weekend... ...Unsettled weather with heavy rain and some high elevation snowfall expected this weekend for the Pacific Northwest... Hurricane Delta continues to advance across the Gulf of Mexico early this morning and is expected to gradually strengthen today back into a major hurricane with CAT-3 intensity. Delta is expected to grow in size as it approaches the northern Gulf Coast, where life-threatening storm surge and dangerous hurricane-force winds are likely beginning Friday, particularly for portions of the Louisiana coast. Storm Surge and Hurricane Warnings are in effect, and residents in these areas should follow advice given by local officials and rush preparedness actions to completion. Significant flash, urban, small stream and minor to moderate river flooding is likely Friday and Saturday in association with Delta from portions of the central Gulf Coast into portions of the Lower Mississippi Valley as the storm brings very heavy rainfall. In fact, the storm is currently forecast to produce as much as 5 to 10 inches of rain, with isolated maximum totals of 15 inches, for southwest to south-central Louisiana. As Delta moves farther inland, heavy rainfall is expected to overspread the Ohio Valley and Mid-Atlantic this weekend. Delta is also expected to produce a threat for a few tornadoes across portions of the Gulf Coast states. Elsewhere across the continental U.S., the weather pattern will be rather tranquil going through the end of the week. However, by early this weekend, as a new cold front settles southeast across the Great Lakes region and a warm front approaches the Northeast, there should be a swath of light rain that impacts areas of New York and northern New England. Meanwhile, a pair of Pacific cold fronts will be impacting the Pacific Northwest this weekend which will bring a surge of rather strong onshore flow and a likelihood of heavy rainfall for the coastal ranges and the Cascades. However, some of the higher peaks of the Cascades will see a sufficient lowering of snow levels to yield a heavy snowfall threat. Temperatures across the country will tend to be below normal across the Northeast and along the Gulf Coast going through the end of the week. Meanwhile, much warmer than normal temperatures are expected across the Great Basin, the Rockies, and the central and northern Plains. Cooler than normal temperatures are expected this weekend along the West Coast. Elsewhere, temperatures will generally be near normal for this time of the year.
