Temperatures will respond to the March sunshine, and that sure was the case Saturday with 62 degrees at BWI. There will be high clouds and some mid clouds Sunday as high pressure slides to our east and some of the moisture coming out well in advance of the next storm system streaks northeastward.
The surface ridge will slide farther east Sunday night and some of the lower level clouds and moisture that will be gathering over at the coast of New Jersey, Delaware and Maryland Sunday in the easterly flow will allow low clouds and patchy fog to fill in westward our area Sunday night.
As we head into Monday, we start with the low clouds and patchy fog, but the lower clouds will partially clear by mid morning. It will still be a mild day, but if we don’t break into occasional sunshine, we will probably be a few degrees too high with our high.
The first of the rain ahead of the next system approaching should hold off until late Monday and continue Tuesday morning. We are still looking at bringing us a good dose of 0.50 to 1.00 inch of rain, occasionally heavy, during an 8-10 hour period.
Timing remains on the models having it ending around noon with some sun even breaking out mid afternoon. We should stay in the relatively mild air with the wet weather Tuesday.
