The balance of the week is a bit bipolar with two more warm days ahead (80s for highs) before a massive cold front sweeps the area on Thursday. A powerful blast of Canadian cooling should push our late week temperatures to the lowest levels since mid-May with highs on Friday in the 60s. Yes, you read that correctly. It may finally be time for you to find and pull out those light jackets. The weekend looks cool too, and it may see a few clouds/showers on Saturday with a better chance for sunshine on Sunday.
Today (Tuesday): Mostly sunny skies and warm temperatures today with max temps reaching the mid-to-upper 80s, a little higher than Monday. Light breezes are mainly from the southwest and west, which should usher in slightly higher humidity. I don’t think we’ll hit 90F anywhere today, but it may feel like it in the afternoon (did you know we haven’t hit 90-degrees at Reagan National Airport in 17 days?). Confidence: High
Tonight: Partly cloudy skies, lows from near 60 in the outer suburbs to mid-to-upper 60s in the city. Light winds from the southwest and west again. Confidence: High

Tomorrow (Wednesday): The warmer flow continues, but we could see a pickup in afternoon cloud cover to offset the warmth a bit. Recent trends have been to slow the cold front down though so mid-80s (83-87) aremost likely under partly to mostly sunny skies. You’ll feel that humidity creep up slightly more again too. And there is a 30% chance of a late afternoon shower or storm. Confidence: Medium-High
Tomorrow night: Partly cloudy and mild with scattered showers and storms (30% chance). Lows from 62-68 (suburb-city) Confidence: Medium-High
Thursday brings the big cold front through our area during the morning hours. The front should be accompanied by showers and storms (60% likelihood), but don’t expect major flooding rains at least. Temperatures stall in the low-to-mid 70s, and winds shift to start coming from the north and northwest during the day. Thursday night sees partly cloudy skies with sharply cooling temperatures into the low-to-mid 50s (we haven’t seen a low below 60F at National Airport since June 15!). Confidence: Medium
Friday looks to be the coolest day since mid-May with highs only in the mid-to-upper 60s. The cool front stalls just to our south and that could mean some showers around, especially in the southern half of our area (30% chance). The good news is that unlike last week, this system does not have a strong moisture supply to threaten flooding rains. Friday night temperatures again dip into the 50s with an outside chance of jacket-inducing upper 40s toward the outer suburbs under partly cloudy skies. Confidence: Low-Medium
The easy part of the weekend forecast is that it will be cooler-than-normal yet. The tricky part is Saturday and determining how close that stalled front from the south gets into our area. For now, we’ll continue with a 30% chance of showers under partly cloudy skies. Highs Saturday in the low-to-mid 70s. Partly cloudy and cool again Saturday night with lows expected in the mid-to-upper 50s. Sunday should be mostly sunny and splendid with highs in the middle 70s. Confidence: Low-Medium
