TODAY’S DAILY DIGIT
A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

5/10: As a father, I can’t dock too much off the digit. But A/C is really the perfect gift as the heat index approaches 100.

Tonight: Staying sultry, chance of isolated storm. Lows: Mid- to upper 70s.

FORECAST IN DETAIL

Happy Father’s Day to all the proud papas out there! Did your dad order hot ‘n’ humid for his weather today? Because that’s what he’s getting. At least we only have an isolated storm risk today. That’s not the case tomorrow, though, with strong to severe storms a real threat as a cold front approaches. Drier air then works in for a nicer midweek.

Today (Father’s Day): Early clouds and some areas of fog may struggle to burn off during the morning, but we should see at least partly sunny skies by afternoon. That helps afternoon highs to near 90 to the low 90s, and with very high humidity, the heat index pushes toward the upper 90s to near 100. With an unstable air mass in place, an isolated thunderstorm is possible mid- to late afternoon. The breeze is a steady one from the south about 10 to 20 mph. Confidence: Medium-High

Tonight: Still warm and humid, with an isolated storm possible. I mentioned warm and humid, right? Overnight lows only fall to the mid- to upper 70s under mostly cloudy skies. At least the breeze stays up, blowing from the south-southwest at 10 to 15 mph. Confidence: Medium-High

Tomorrow (Monday): A cold front working through this hot and humid air is a good recipe for thunderstorms, and we’re likely to see some on Monday. A shower or storm is possible through the morning. But the best chance of strong to severe storms comes during the afternoon into evening, with the potential for very heavy rain, flash flooding and damaging winds. Otherwise it’s a mostly to partly cloudy day, with highs topping out in the mid- to upper 80s. Confidence: Medium

Tomorrow night: The threat of strong to severe storms continues into the evening hours, but most of the action should be clear of the area by around midnight or a bit after. Drier air slowly works in overnight behind the front, with more comfortable lows in the upper 60s to low 70s. Confidence: Low-Medium

A LOOK AHEAD

Tuesday and Wednesday bring a nice break from the stifling humidity. It’s still mid-June in Washington, so I wouldn’t exactly call the air refreshing. But both days look fairly nice overall, with somewhat drier air, and highs reaching the mid-to-upper 80s under partly sunny skies. Just a slight chance of a shower or storm each day. Confidence: Medium
