Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 308 AM EST Sun Nov 10 2019 Valid 12Z Sun Nov 10 2019 - 12Z Tue Nov 12 2019 ...The coldest air mass so far this season is surging into the northern Plains... ...Snow is expected to spread from the northern Rockies into the central Plains and the Midwest today into Monday... ...Snow and mixed precipitation is forecast to reach New England Monday night and continue into Tuesday. An expansive area of high pressure originated from Siberia has traveled across the Arctic Ocean and is now dominating western Canada. The leading edge of arctic air associated with the high pressure system is now edging southward across the northern Plains. This will spread the coldest temperatures so far this season across the eastern two-thirds of the country during the next few days. In fact, record cold high temperatures are forecast for Monday for many locations across the upper Midwest, with below-freezing temperatures reaching central Texas by Tuesday morning. This will make it feel like in the middle of January rather than November. In addition to the cold, snow is expected to develop behind the arctic front, first across the northern Rockies this morning, then spreading south and east into the central Plains on Monday. A narrow zone of mixed precipitation can be expected on the southern periphery of the snow as well. Later on Monday, the snow is forecast to develop quickly across the Great Lakes and into New England as an area of low pressure forms along the arctic front and tracks toward the Northeast. Some snowfall accumulation is expected for interior New England and into the northern Appalachians by Tuesday morning as the low center tracks just to the south. A narrow zone of mixed precipitation can be expected on the southern periphery of the snow as well. Meanwhile, rain is expected to spread quickly across the Deep South Monday night and early Tuesday ahead of the arctic front. Across the western U.S., dry and warm conditions will continue to raise concerns of fire weather, especially for southern California.
