by

* Heat warning from 12:00 to 20:00 *

A somewhat subjective assessment of the day’s weather, on a scale of 0 to 10.

1/10: Stubborn sticky, stagnant stench from high temperatures that won’t go away.

  • Today: Partly sunny, chance of an afternoon storm. Highs: 95-100.
  • This evening: Partly cloudy, very muggy. Lows: 75-80.
  • Tomorrow: Partly sunny, chance of thunderstorms in the afternoon. Highs: 93-97.

The weather misery index is skyrocketing, with both temperatures and humidity nearing maximum levels of discomfort in July. There doesn’t appear to be any significant cold fronts coming in to “save the day.” But we are seeing a dying front that could provide a brief cooler Friday, and increasing storm chances late in the week as we try to combat our increasing drought conditions, which are especially concerning west of DC.

Today (Tuesday): Foggy, warm and humid with a mix of sun and clouds as highs climb back into the mid 90s to near 100. Higher humidity (dew points in the low to mid 70s) will push heat index values ​​above 105, so extreme caution is advised for any level of outdoor activity. Winds out of the south at around 5 mph won’t help matters. Isolated, small thunderstorms are possible in the late afternoon to early evening. Confidence: High

This evening: Extremely humid conditions remain with lows in the mid 70s to near 80s along with partly cloudy skies. A light breeze continues to blow from the south at around 5 mph. Confidence: High
