Rainfall totals in Maryland over the past week.
(National Weather Service)

Some rain showers left over from the cloudy, wet system that has moved through early this week could pass through today. But otherwise, there should be an about-face in the weather.

Beautiful weather is expected to arrive and stick around through the weekend and the Preakness. The sun is out Wednesday morning, but humidity remains high. Dew points have been in the 60s all week at BWI Marshall Airport, which means most people perceive an uncomfortable stickiness in the air.

Of course, any rain is welcome. The wet system dropped anywhere from half an inch to more than 2 inches of rain around the state. The official count at BWI was at the low end of that spectrum, with precisely half an inch since Monday morning.

But heavy rain fell where it was needed most, in Worcester County on the lower Eastern Shore, with between 2 and 3 inches across most of the county over the past week. Two inchoes of rain or more was also recorded along the border between Baltimore and Carroll counties and around Bel Air in Harford County. See the map above to estimate the rainfall total where you are.

The moisture should clear out when a cold front passes through tonight. Forecasts are right around normal – average highs in mid-May are around 74 degrees, with lows around 52 degrees.

Perfect timing for graduation and Preakness parties filling up schedules this time of year.
