Thursday, the forecast computer models indicate the most significant disruption of travel based on the forecast weather conditions. “Holiday travelers should prepare for winter driving conditions by packing chains, warm winter clothes, and extra food and water,” the Sacramento weather office said. Snow chances in western Nevada increase late week, added the Reno office, so be prepared for major travel disruptions over the Sierra by Wednesday. “Longer-duration winter storm watches for the Sierra and northeast California will start late Wednesday afternoon as a significant period of winter weather affects the region through the Christmas Holidays,” the Reno National Weather Service office said. The higher inland elevations expect an onslaught of more snow, a rapid change from the snow drought they were just in. Multiple storms will move through the West, with western Oregon into the Sierra Nevada, likely to see the highest five-day totals. Major coastal cities like Los Angeles and San Francisco are preparing to receive more rainfall in waves ahead of Christmas. “The next push of Pacific moisture arrives Tuesday evening into Wednesday with more lower elevation rain and accumulating mountains snow, this time extending as far south as central California,” the WPC said.Ī category 3 atmospheric river is forming near Hawaii and will create a pipeline of moisture into the West this week. But each storm cloud brings a little hope for those in the drought-stricken states and those looking to ski this holiday season. It will be the one area of the country to see the most consistent travel disruptions. After a brief lull Tuesday morning, the storm factory will deliver storm after storm for the West Coast all the way through Christmas. “This system then reaches the upper Great Lakes by Tuesday night where several inches of snow are possible.”įeet of fresh snow is forecast across the Cascades, Sierras, and northern to central Rockies this week ahead of the holiday weekend. “Some thunderstorms could produce damaging wind gusts, tornadoes, and waterspouts.”Įxpect some minor to moderate delays in all the major airports across Florida Tuesday.Īfter dumping more than an inch of rainfall across northern Florida, southern Georgia, and far southern South Carolina, the storm system will quickly push off the eastern coast by Wednesday.Īcross the northern tier of the country, a quick-moving wave of low pressure in Montana will produce light snow accumulations across the Northern Plains late Monday into early Tuesday, the WPC said. Either way, “by early Tuesday morning the storm will have strengthened and a threat of heavy rain and thunderstorms, some of which could be severe, is expected across most of the Florida Peninsula,” the Weather Prediction Center said. It means there is a slight possibility this could become a named subtropical storm. Right now, as my colleague Chad Myers pointed out, the water temperature in the Gulf of Mexico, which helps fuel these storms, is a little bit warmer than normal more like ocean temperatures in November, the end of hurricane season. If this storm were forming in the Gulf of Mexico about two months earlier, I might be a little more worried it would become a tropical storm. A low pressure system in the Gulf of Mexico is forecast to bring heavy rain and severe storms to Florida on Tuesday.
