Periods of rain can be expected for your Memorial Day. A front will slide into Northern VA and stall for the holiday. It’ll serve as a trigger for scattered-numerous showers as there will be an abundance of moisture available for rain to form.
Timing for rain looks to be throughout the day; so, make sure to prep for rain if you’ll be out-n-about on Memorial Day. Also, outdoor events should have a back-up indoor plan just in case (or tents).
Until then, the pattern will be conducive for lower rain chances…but it’ll be very hot and muggy courtesy of a SW flow. There won’t be a real “trigger” in our area for widespread showers today. So, the rain coverage will be isolated this afternoon…being sparked mainly due to the heat of the day. However, if you catch a shower…expect heavy downpours. Highs will be near 90°. Sunday looks similar, but there will be a few additional showers as the previously mentioned front begins to slide towards us.
Alberto continues to battle wind shear (change in wind speed & direction with height); so, it continues to have trouble organizing. It’s already bringing rain to Southern & Southwestern Florida. As it moves over the Gulf through Monday, it’ll spend a good amount of time over warm waters which could fuel & further strengthen it (even with the upper-level winds interacting with it). Regardless, flooding remains a high risk along with rip currents for the Gulf Coast. As of this Morning, Tropical Storm Watches were in effect for the Gulf Coast from SE Louisiana to the FL Panhandle. It looks like it’ll move ashore around Tuesday… stay tuned.
