Ready for a truly summer-like pattern?  Today: warm, tomorrow: warmer, Thursday: warmest!  A warm front passing through today drives the humidity and temperatures gradually upward this week, with the possibility of multiple days near or above 90.  This warm and humid pattern continues through the weekend, before a potential cold (more like “cool”) front approaches early next week.

Today (Tuesday): Textbook warm-front weather.  Expect ample clouds today with a 50% chance of showers and thunderstorms (intermittent throughout the day).  Pack an umbrella for any scattered storms that come your way.  A warm front lifting overhead kicks our temperatures up a notch as well as the humidity levels. Highs near 80 area-wide. Confidence: Medium-High

Tonight: Scattered showers and storms persist throughout the evening.  Will be a mild night with lows in the low to mid-60s for counties north and west of the District, and closer to 70 for downtown and the counties south and east. Confidence: Medium-High

Tomorrow (Wednesday): Day 1 of our first heat wave of the season: the heat and humidity arrive.  High temperatures will climb to near 90 across the region, and dew points soar into the mid-60s thanks to moist southerly flow.  Partly cloudy skies should provide some occasional relief, but this is the type of day we’ve all been enjoying the last several “cooler than normal” days a little extra for… Confidence: Medium-High

Tomorrow night: Another mild night.  Low temperatures range between the mid-60s to low 70s depending on location; same song and dance as Tuesday night where you’ll find the cooler overnight lows north and west of downtown. Confidence: Medium-High


Day 2 of the heat wave.  Thursday will be similar to Wednesday with high temperatures and unpleasant humidity.  Dew points remain in the mid-60s, and high temperatures could be a click higher than Wednesday due to fewer clouds; low to mid-90s.  Expect mild temperatures again on Thursday night; mid-60s to near 70. Confidence: Medium

Day 3 of the heat wave.  As high pressure remains anchored overhead, Friday is essentially a clone of Thursday with highs in the low to mid-90s with high humidity.  Friday night is also a carbon copy of Thursday night.  Mild, with lows in the mid-60s to near 70. Confidence: Medium

Weekend: Does the weekend bring relief from the weekly heat wave?  Unfortunately that does not appear to be the case.  Both Saturday and Sunday will host highs in the upper 80s to near 90 and boast high humidity with partly to mostly sunny skies. An isolated thundershower is possible Saturday, with a somewhat better chance Sunday as a cold front gets closer. Confidence: Low-Medium
