A refreshing burst of Canadian coolness is now sweeping into our area, eradicating the heat and humidity of the past few days. We’re on track for at least two spectacular days today and tomorrow and possibly more to follow. The weekend is more of a mixed bag with Saturday having the better chance to stay dry and Sunday showing an increasing risk of showers, but still a good bit of uncertainty at this point. What is almost certain, however, is that we have no 90s anticipated through early next week!

Today (Wednesday): The first of a trio of tremendous weather days as Canadian cooling comes in full force to chase the dog days of summer away.  High pressure builds in and flushes the area with low humidity (dew points could dip into the 40s this afternoon), holding temperatures below normal with highs only in the upper 70s to near 80. Mostly sunny skies complete this pretty picture as breezes flow from the north and northwest near 15 mph with gusts near 25 mph.  Confidence: High

Tonight:  Mostly clear and cool with very low humidity as temperatures plummet into the 50s in most areas.  Parts of the city should hold in the very comfortable upper 50s for lows, while the outer suburbs aim for quite cool conditions in the low 50s (the record is unreachable down in the 40s out at Dulles). Light breezes from the north. Confidence: High

Tomorrow (Thursday):  Sequels are rarely as good as the original, but in this potential trilogy of Nice Days, I believe Thursday will be just as great. Skies look to be sunny with low humidity, light winds, and temperatures delightful once again with highs in the upper 70s to low 80s. Confidence: High

Tomorrow night:  Another very comfortable evening is heading our way with lows ranging from the middle 50s to low 60s as the skies stay mostly clear and the winds light. Confidence: High


Friday should be another fantastic day for our triple play of Canadian cooling.  There is a chance that clouds increase some during the afternoon, but for now it looks like they’ll hold off late enough to qualify as a mostly sunny day. Highs are again only in the upper 70s to low 80s.  Friday night sees partly cloudy skies with slightly warmer lows in the low-to-mid 60s. Still not bad for mid-August! Confidence: Medium

The weekend forecast is a bit more complicated. Saturday is probably the better day with highs in the low-to-mid 80s, partly cloudy skies, and a 30% chance of showers mainly south of D.C. Saturday night looks to be partly to mostly cloudy with a 30% chance of showers area-wide and lows in the 60s. Sunday continues partly to mostly cloudy with highs in the upper 70s to mid-80s and a 50% chance of showers as a disturbance tries to move closer from the south. There’s still a chance the system stays too far south, keeping the weekend mostly dry. Confidence: Low
