SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1258 AM CST Mon Nov 13 2017 Valid 141200Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected across the U.S. Tuesday. ...Synopsis... Low-amplitude flow aloft is forecast across the U.S. Tuesday, as a trough crosses the eastern U.S. and relatively zonal flow expands to cover much of the country in its wake. A short-wave trough crossing the Canadian Prairies and north-central U.S. will reach the upper Mississippi Valley/western Upper Great Lakes area late, while a much larger trough/low remains just off the Pacific Northwest Coast through the period. At the surface, high pressure will largely prevail, though a rather weak cold front will cross the Plains in conjunction with the aforementioned north-central U.S. upper short-wave trough. As the system moves east toward the mid-Mississippi Valley area late in the period, scattered/elevated showers and a couple of thunderstorms should develop within a zone of warm advection/quasi-geostrophic ascent -- focused over the IL/MO vicinity. Meanwhile, showers and a few/occasional lightning strikes will persist near the Pacific Northwest Coast, while showers and a couple of thunderstorms occur over the Florida Peninsula. In all areas, severe weather is not expected. ..Goss.. 11/13/2017 Read more
