The two-thirds-of-an-inch the airport has recorded will be just a drop in the bucket by Monday if forecasters at the National Weather Service are correct in their predictions for the late-winter rainstorm headed our way.

There are Flood Watches posted for the entire state today through Saturday evening. Forecasters say the heaviest rain is due Friday night and Saturday, with 2 to 4 inches possible by the time things begin to taper off on Monday.

That much rain, coming on top of a heavy snow meltdown that has saturated the soil and kept the creeks full, will mean flooding for small creeks, streams and urban areas this weekend. And when all that reaches the larger rivers, we should expect those waters to spill over their banks, as well. You can track the flooding here.

The Flood Watches for the Eastern Shore call for even more rain - 3 to 5 inches. That's one to two months worth of normal rainfall in just four days. Do not attempt to drive through flooded roadways.

Here's AccuWeather.com's take on the rain, with their rainfall forecast map. And here is Mr. Foot's Forecast.

The wet weather is being brought to you by a slow-moving low-pressure system that has been dawdling our over the Central Plains. The counter-clockwise circulation around that low has been dragging warm, moist air off the Gulf and the Atlantic, and delivering about 0.66 inch of rain at BWI-Marshall overnight.

Next up: A secondary low now forming over the southeast coast. The counter-clockwise circulation around that coastal low will begin to throw onshore easterly winds across Delmarva from the Atlantic. By tonight and Saturday, the rains will become heavy at times, delivering the bulk of the weekend rainfall.

The whole mess will be slow to pull away, so we can expect the drip to continue through Sunday and into Monday. We should get back to sunny skies and mild temperatures by mid-week.
