Today’s Daily Digit

A somewhat subjective rating of the days weather, on a scale of 1 to 10.

What else can it be for the infamous trio of hazy, hot, and humid? But can’t we streamline it? How about “Hazmidot” or “Hotzymid”, or my favorite “Humotzy”?!

The string of 90+ days will continue to pile up like afternoon traffic on the beltway for the rest of the week. However, an honest to goodness cold front is set to clear this jam in no uncertain terms. It is likely to be a noisy affair with the potential for some severe storm especially north of the city late Saturday. After that, a string of much nicer days with highs in the 80s and more manageable humidity.

Today (Thursday): Sun is in full control, albeit a bit hazy. The heat and excessive humidity are immovable, literally, as winds are nearly calm. Highs reach the mid-to-upper 90s, still well under the records for the day. A few clouds pop up in the afternoon for an occasional minute of shade but rain chances are minimal. Confidence: High

Tonight: For most it is another twinkly star, humid evening but for a select few there is a (less than 20 percent) chance of a thunderstorm. Indoors with AC is the way to go as evening reading are still upper 80s to lower 90s. Winds are still missing in action. Lows end up in the mid-70s burbs, upper 70s to near 80 downtown. Confidence: High

Tomorrow (Friday): The sun is strong as ever but the change is likely to be a bit more of a wind from the southwest (5-15 mph). This might actually drop the dew point a few notches but makes hotter temperatures a greater likelihood. Most see upper 90s and a stray 100 F reading is quite possible, still no record though. This leads to greater instability in the atmosphere and gives us a 40 percent chance of thunderstorms by late day. If you are one of the lucky ones, some brief but blessed cooling is welcome. Hopefully without a power outage! Confidence: Medium-High

Tomorrow night: The chance for storms is likely to quickly die out by sunset. Skies clear letting a nearly full moon light the night. Lows remain stuck in the mid-to-upper 70s. Confidence: Medium-High


Saturday starts out like all the others before it with hazy sunshine and plenty of humidity. However, clouds should start popping up quickly by midday. Thunderstorms should be just widely scattered until late in the day when there is a good chance (70 percent) for a line of thunderstorms to march south across the region ahead of the cold front. While a few severe storms are likely with the front, it is still too early to know just what the extent will be for sure. Highs still reach the low-to-mid 90s before the action begins. Scattered thunderstorms could linger well into the night with lows in the low-to-mid 70s. Confidence: Medium

Sunday should start out quieter but the atmosphere is still likely to be unsettled and pop up thunderstorms are a decent bet (50 percent chance) by afternoon, especially south of the District. This should finally break the string of 90+ days with highs mainly in the mid-to-upper 80s. Things should quiet down in the evening hopefully in time to see the full moon rise. It is often called the Thunder Moon so it may be appropriate this time! Lows fall to refreshing levels of upper 60s to lower 70s. Confidence: Medium

Monday should be quieter under partly sunny skies as most of the thunderstorms stay to our south. Highs reach the mid-to upper 80s but with noticeably lower humidity, it feels pretty darn good. Confidence: Medium
