My biggest knock on this day is being tied to the umbrella. You know as long as you have it, it won’t rain! Get the Digit on Twitter| Discuss on Facebook


Welcome to the tropics. The only problem is that while all of us experience the moderate humidity, needed rains are probably hit or miss. Some could be treated to a good downpour today, with others seeing a lot less. Repeat performances are likely through Thursday. Right on time for the holiday weekend comes the sun and the heat. Might we see the season’s first 90-degree day??!!

Today (Tuesday): Any morning precipitation is likely in the form of drizzle. After some early-morning fog, clouds should tend to dominate through the morning, but a few glimpses of afternoon sun should support highs at least in the mid-70s if not near 80. The remains of a Midwest front may graze the area in the afternoon and set off more in the way of showers (60% chance) and possibly a narrow line of thundershowers. Confidence: Medium-High

What is the Storm Threat Level?

Tonight: The clouds hold tight as does the humidity, but any early-to-mid evening showers (50% chance) become isolated by late evening. Barely a breeze to be felt but evening temperatures are very pleasant as they hold in the 70s. Overnight lows are mainly in the low-to-mid 60s. Confidence: Medium-High

Tomorrow (Wednesday): The sun remains elusive today, though some glimpses are possible, as clouds hold the upper hand. The morning should be mostly dry. But the afternoon is likely to become increasingly showery as an upper-level area low pressure drifts into the area. Around 60-70% of the area could see showers and thundershowers blossom. Highs should reach near 80 to the low 80s before any cooling rain. Confidence: Medium

Tomorrow night: Showers and thunderstorms may linger into the evening (60% chance) before drying up overnight. Humidity helps to keep readings quite pleasant - in the 70s all evening, then bottoming out in the low-to-mid 60s. Confidence: Medium


Thursday shows little imagination with the same old partly to mostly cloudy skies and a 60% chance of showers and a few thundershowers during the afternoon into early evening. Winds are light except for a stray gust from one of the more vigorous downpours. Showers should dissipate by mid-evening, aiding early getaways to the beach. Lows hold up even more overnight with mid-to-upper 60s prevalent. Confidence: Medium

Friday gets tricky as an offshore high-pressure area may crank up the flow off the ocean. This is likely to give the Eastern Shore some fog and low clouds. Even the D.C. area could see considerable clouds early before increasing sun. Highs should range from the low-to-mid 80s in the sunnier metro area, to the mid-to-upper 70s along the coast. At least rain chances are lower, but not zero, for the mad dash to the beach. Friday night lows only slip to the mid-to-upper 60s. Confidence: Low-Medium

Saturday through Memorial Day definitely ushers in the start of summer in style. Skies are partly to mostly sunny and highs look like they’ll explode to the upper 80s to low 90s, with lows in the mid-60s to low 70s. Shower and thunderstorm chances appear to be down, but maybe not completely out. Keep the lemonade handy and slather on that sunscreen. Confidence:Low-Medium
