Active weather with heavy precipitation expected in the southeast and west through the weekend while above-average highs are expected between these regions in the Plains and Midwest.
In the southeast, a low-pressure system will gradually develop by late tonight or early Saturday in the northern Gulf of Mexico and move east northeast over the weekend and making it somewhere in the vicinity of Southern GA and northern FL by Monday morning. Initially, scattered showers and a few storms will occur in southern TX today, and build east northeast into southeast TX and southern LA this evening and overnight. Precipitation is expected to become more widespread early Saturday in eastern LA, southern MS, and southern AL and build east northeast through the rest of the weekend possibly getting as far north as southern TN and east as the western Carolinas by Saturday night, and as north as KY and the southern VAs and east as the eastern Carolinas on Sunday. Widespread rains of a few inches are likely with the highest totals at least in the 3-5 inch range possible coming in eastern AL, southern and central GA, northern FL, and southern SC.
In the west, a trough will be slow to move onshore leading to heavy rainfall in western WA and northwest OR today and tonight, building southward through western OR and into northwest CA Saturday and Saturday night, into western and central CA Sunday, as far south as southern CA Sunday evening and east to Las Vegas towards Monday morning.
In between all the precipitation will be some nice weather for the Plains and Midwest where above average highs are expected with widespread mid to upper 60s as far north as western KS and eastern CO on Sunday and maybe a few more 60s even further north into western NE, southwest SD and possibly far eastern WY.
