Unfortunately its another weekend of rain. Not only was it our 15th consecutive Friday with measurable rainfall but instead our 19th consecutive combination of Fridays, Saturdays, and Sundays since 2019 began with wet weather. Rain showers are expected to return to the area later this evening (May 11, 2019) as our first wave of low pressure rolls along the front. This will be a succession of three separate pieces of energy along our stalled frontal boundary that looks to enhance the rain threat and fall in temperatures for Mother's Day.
Rain picks up in intensity overnight into Sunday morning before tapering back to showers. Heavy rain moves in Sunday (May 12, 2019) afternoon with maybe a few rumbles of thunder. Severe weather will stay to our south since temperatures in many locations will barely make 60 degrees Mother's Day afternoon.
Some spots in northern Maryland may even be stuck in the upper 40s and low 50s for much of the day. Jackets and umbrellas will be the tools of choice to protect Mom as you take her out to celebrate. Curbside service for dinner or lunch also helps as well. Looking back into weather history over the last 6 years when it comes to Mother's Day it looks as if we will be right on par with what happened in 2018 just a bit cooler. Rainfall amounts will be much high though with many locations receiving 1-2" through Tuesday morning.
The system departs the region on Monday but with it's close proximity rain chances along with cooler temperatures continues. Showers will be at there heaviest during the morning and early afternoon hours before things wrap up late in the day Monday. Cool conditions will prevail though as highs struggle to make 60 degrees. Tuesday brings continued chances for light showers early before the sunshine finally breaks through.
Better chances for sunshine and warmer conditions by the middle of next week. The early call on the Preakness remains mostly dry with a passing late day shower and highs in the mid 70s. This fits in well with the 8-14 day projections for above normal temperatures and below average precipitation going into the middle of May.
