Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 326 AM EST Fri Feb 23 2018 Valid 12Z Fri Feb 23 2018 - 12Z Sun Feb 25 2018 ...Heavy rain possible from parts of the Southern Plains northeastward to the Eastern Ohio Valley... ...Heavy snow possible over parts of the Upper Mississippi Valley/Upper Great Lakes... ...Heavy snow possible over the Cascades and Northern Rockies... ...Rain/freezing rain possible over parts of interior New England... A storm over the Upper Great Lakes/Upper Mississippi Valley will move northeastward into Southeastern Canada overnight Friday. The system pulls a front extending roughly from the Western Ohio Valley to the Western Gulf Coast that will move eastward off the Northeast/Northern Mid-Atlantic Coast then westward to a wave of low pressure over the Middle Mississippi Valley by Saturday evening. Snow will develop over parts of the Northern Plains to the Upper Mississippi Valley/Upper Great Lakes that will lift northeastward into Canada by Friday evening. Showers and thunderstorms will develop along and ahead of the front from the Western Gulf Coast/Southern Plains to the Ohio Valley that will lift northward into parts of the Middle/Lower Mississippi Valley by Friday evening. Additional showers and thunderstorms will also develop over parts of the Central Gulf Coast by Friday evening. In addition, rain will develop over parts of the Central Appalachians into the Mid-Atlantic that will move into parts of the Northeast by Friday evening with snow developing over parts of Northern Maine. The rain will move off the Northeast Coast/Northern Mid-Atlantic Coast by Saturday morning. A region of rain/freezing rain will develop over parts of interior New England Friday into Friday evening. Meanwhile, a developing wave of low pressure over the Southern High Plains will move northeastward to the Middle Mississippi Valley by Saturday evening. The associated front will move from the Southern Rockies/Southwest northeastward to the Middle Mississippi Valley/Western Gulf Coast by Saturday evening. The storm will produce snow over parts of the Great Basin/Southwest and the Central Rockies that will move northeastward into parts of the Central Plains and Central/Southern Rockies by Saturday morning. The snow will continue to move into parts of the Northern Plain/Upper Mississippi Valley by Saturday evening. Overnight Friday, showers and thunderstorms will develop along and ahead of the associated boundary over the Southern Plains that will move to the Middle/Lower Mississippi Valley by Saturday evening. Elsewhere, two areas of upper-level energy will move into the Pacific Northwest overnight Friday into Saturday morning continuing into parts of the Northern Intermountain Region/Great Basin by Saturday evening. Additionally, onshore flow will develop over the Pacific Northwest on Friday continuing into Saturday evening. The energy and onshore flow will aid in producing coastal rain and higher elevation snow over parts of the Pacific Northwest into parts of the Northern Rockies by Friday evening. The snow will expand into parts of the Northern/Central Rockies and Northern California/Great Basin on Saturday into Saturday evening. Coastal rain will also move into parts of Northern California on Saturday into Saturday evening, too.
