Thursdays SEVERE WEATHER OUTLOOK has a GENERAL T-STORM RISK for isolated to widely scattered thunderstorms in the forecast for today and this evening across portions of Texas into the Lower MS Valley. We do NOT anticipate anything strong or severe in the forecast. Thursdays NATIONAL WEATHER FORECAST SUMMARY By: Forecaster, David Saurer Happy New Year, 2015. Pretty active weather pattern taking shape across the Southern Plains and Lower MS Valley to begin the New Year. An upper-level closed low pressure center over the Desert Southwest will begin to slowly advance Eastward to the Southern Plains by tomorrow PM. In the meantime, this system will be responsible for producing snowfall over portions of the Southwest and into the Central and Southern Rockies for today and through most of your Friday AM. As this system advances Eastward, expect the moisture tap from the Gulf of Mexico to overrun the associated frontal boundary along the Gulf Coast and as it does, we can expect rainfall to develop over the Southern Plains that will expand to the Gulf Coast and Southeast by tomorrow PM. The bigger story and possibly causing a lot of travel headaches will be the area of rain and freezing rain that will begin to develop over portions of the Southern Plains for this afternoon and into the evening hours. Light ice accumulations is possible as WINTER STORM WATCHES and ADVISORIES ARE POSTED for most of NORTHERN TX and INTO OK. Snowfall will be developing over parts of the Southern Plains for Saturday PM as the colder air will continue to filter in from Southern Canada. Stay up to the latest forecast and advisories with NOAA Weather Radio and the NATIONAL WEATHER SERVICE. In the meantime, another area of weather concerns switches to the Northern Plains and Upper MS Valley where a frontal boundary is advancing Eastward to the Northeast/Great Lakes region by tomorrow PM. This disturbance will begin to produce snowfall over the Upper Great Lakes that will expand itself into the Lower Great Lakes by this evening. The snowfall over the Lower Great Lakes will begin to fade out by Friday PM. The bigger issue is the wave of low pressure that will begin to dig Southward out of Western Canada and will begin to advance into the Northern Plains to the Upper MS Valley for your Friday. Snowfall will then develop over portions of the Northern Plains and advancing into the Upper Great Lakes by Friday PM. Finally, wrapping up the summary, we look over at the Pacific Northwest where some Pacific onshore flow will sweep in and produce some lower elevation rainfall with higher elevation snowfall in the forecast for portions of Western Washington by Friday PM.
