An upper level trough of low pressure (the “U” shaped dip in the yellow line) is moving eastward and another one will replace it. It’s starting to warm up again, but will cool a bit Wednesday. It will warm up later in the week into the weekend as high pressure builds in and it should stay dry. Look for another weak cold front to brush by next weekend and then waffle and get pushed back as a warm front and then move through again. Still no rain. There could be some sprinkles along the far North coast as the Wednesday upper low moves into position.
