Muggy but tolerable with clouds slow to clear. While I prefer today’s 80s over 100 degrees, I’m ready for more sun. Get the Digit on Twitter| Discuss on Facebook

FORECAST IN DETAIL


Have you enjoyed our break from the heat? Good, because it’s almost over. After today’s lingering clouds and still below-average temperatures, though about 10-15 degrees warmer than yesterday’s record cool, we’re back to at least a couple hot, humid and potentially stormy days - the kind which we’ve become quite familiar with this summer. There’s hope that a cold front can break the heat and storm chances by Wednesday, but summertime cold fronts are hard to predict this far out.

Today (Sunday): We’re still dealing with mostly cloudy skies and possible mist or drizzle through early-to-mid morning, courtesy an easterly fetch off the Bay & Atlantic. More of a southerly flow should help turn skies partly sunny during the afternoon and lift highs to the low-to-mid 80s. Can’t rule out an afternoon sprinkle. Confidence: Medium-High

Tonight: Generally we can expect a quiet night even if overcast tries to reclaim the sky overnight . Luckily for folks with outdoor plans, evening chances of rain are slim to none with a slight chance of showers toward morning. Light breezes around 5 mph should help move that otherwise stagnant (and muggy) air just a bit. Lows range from near 70 outside the Beltway to the mid-70s downtown. Confidence: Medium-High

Tomorrow (Monday): Our familiar summertime regime returns with partly sunny skies and humid air. We may add another day to the 90+ count as highs top out from near 90 to the mid-90s. We could have thunderstorms (40-50% chance, especially in the afternoon) give some areas more welcome rain, but we may have to deal with some of them being strong or severe. Breezes should be around 10 mph from the west. Confidence: Low-Medium

Tomorrow night: Shower and storm chances decrease by mid-to-late evening, followed by partly to mostly cloudy skies and muggy lows in the 70s, maybe as high as the upper 70s to near 80 downtown. Confidence: Medium

A LOOK AHEAD

Tuesday shapes up similar to Monday with partly sunny skies and temperatures heating up toward highs in the low-to-mid 90s. We’ll have our eye on storms that could try to pop-up locally, but also might march toward us in a more organized fashion from the north and west with an approaching cold front. Overall chance of showers and storms at this point is in the 30-40% range. Confidence: Low-Medium

Assuming Tuesday’s cold front clears the area, then Wednesday looks like a mostly sunny day with highs near 90 to the low 90s and lower humidity. The other scenario, if the front stalls out nearby, is a more humid day with a continued chance of showers and thunderstorms and highs in the 80s to near 90. Confidence: Low
