Finally we have a mild Saturday and Sunday in store. There is an area of high pressure sliding away to our south and east today. This ahead of arctic cold that trails low pressure crossing into Quebec. Fortunately, this helps us warm today, though we still fall well short of average (48 degrees). There will be some mid and high clouds at times and can be totally overcast at times. Meanwhile, satellite depicts the upper level low nearing the California coast that will start to open up and weaken later today and tonight as it moves inland… then track eastward across the country. It eventually exits the East Coast to our south late Monday or Monday night. Meanwhile, arctic cold from the north will push southward through Sunday night. Where moisture out ahead of the California system and the arctic front get in cahoots… there is going to be the much heralded snow on the way. Heaviest precipitation is on our northern fringes. Thinking is ~ 6 inches is a good estimate for BWI-Marshall right now with higher amounts just to the north and west where the colder air and moisture are more in line for all snow, and less amounts to the south where the change to snow may wait until Monday morning.
