A weak upper level disturbance will pass Monday, but rain showers will primarily be limited to southwestern West Virginia. We’ll simply see a few passing clouds and perhaps some light and patchy fog Tuesday morning as that system brushes past. Rain will be slow to develop in the Morgantown area as weather models push the ETA for another low pressure system back to late Wednesday. Models continue to show agreement on that system which will produce gentle rain showers beginning Wednesday evening. Partly cloudy skies and a few light rain showers will persist Thursday.
A strong upper level low pressure system will develop from the Pacific coast Monday and will slice through the continental U.S, gaining strength as it advances. This system will move into our area by Friday, bringing lots of moisture. It could potentially dominate the eastern U.S, drawing moisture from the Atlantic coast. High pressure in Canada and the far northeastern states could block the low, preventing its advance into the northeastern seaboard. This would provide the ingredients for the closed low pressure system to wrap around, delivering steady rain to much of the eastern U.S. Friday, Saturday and Sunday. In any case, the aforementioned precipitation will be in the form of rain as overnight temps hold steady in the upper 30s until Monday. Stay tuned as we may see a rain/snow mix Monday. Will continue to keep an eye on the track of that low for next weekend and will also track any potential water hazards however unlikely they may be.
High pressure to the north prevents the low from advancing. Low pressure "sits & spins" providing steady rain next weekend.
