Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 204 AM EST Sun Jan 12 2025 Valid 12Z Sun Jan 12 2025 - 12Z Tue Jan 14 2025 ...Critical fire weather conditions will continue for southern California into early this week... ...Clipper system to bring snow showers to the Great Lakes along with renewed surge of Arctic air to the Upper Midwest and Ohio Valley... ...Rain for the central Gulf Coast today and Georgia/Florida on Monday... Snow showers that were ongoing early Sunday morning from the northern Great Basin into the northern and central Rocky Mountains will begin to taper off today as a surface low tracks toward the Great Lakes region. Snow showers will linger through Monday from parts of Montana into the High Plains near a strong frontal boundary but snowfall intensity will be decreased compared to what occurred Saturday/Saturday night. The surface low moving into the Great Lakes will have a trailing cold front that will sweep across the Ohio Valley by Monday morning, bringing a renewed surge of Arctic air in its wake. High temperatures that are only in the single digits and teens will affect the northern Plains today with the cold, clipper-like system continuing eastward through Tuesday morning with high temperature departures of 10 to 20 degrees from normal following in its wake, reaching the Midwest on Monday and East Coast for Tuesday. Snow showers will likely track with the front as it moves east across the Upper Ohio Valley into the Northeast on Monday, briefly reducing visibilities. Fire weather concerns will remain across coastal locations of southern California today with winds gusting between 30-50 mph early this morning. Weakening winds are expected into this afternoon/evening as the pressure gradient weakens across the region. However, a resurgence of gusty winds is forecast Sunday night into Monday across southern California as mid-level impulses sink south across the western U.S., allowing for a re-tightening of the surface pressure gradient and gusty downslope/offshore winds. For the Gulf Coast, an area of low pressure will form along a remnant frontal boundary over the open Gulf waters Sunday night and track toward the central Gulf Coast. Rain will increase in coverage late this morning across the upper Texas coast into southern Louisiana and steadily move east through Sunday night. By Monday morning, rain will be affecting the Florida Panhandle into portions of southern Alabama/Georgia but rainfall intensity will diminish throughout the day on Monday. While some light rain may continue over Florida near a frontal boundary Tuesday morning, much of the U.S. will see relatively quiet weather.
