We've reached the point in the calendar when average temperatures are now falling. The likelihood of oppressively hot and humid days diminishes while comfortably warm days become more commonplace. Although the balance of this week will be hot, it will be a notch cooler than last week (and nowhere near as humid) and the weekend may well give us an early taste of September.
TodayHot, not all that humid.
Mostly sunny skies in the morning will become partly to mostly cloudy by late afternoon as a weak cold front approaches. The front won't have much moisture to work with, so only an isolated storm is possible in the late afternoon or evening (less than a 20% chance). High temperatures should range from 89-93. Mostly clear skies overnight with refreshing lows of 60-65 (suburbs-city).

TuesdayNot as hot -- nice day.
Temperatures will be about 5 degrees cooler behind the cold front. High pressure to the north will bring us mostly sunny skies and high temperatures in the mid to upper 80s. Overnight, expect clear skies and lows again 60-65 (suburbs-city).
A hot pool of air to the southwest will move into the region, rapidly boosting high temperatures back into the low to mid 90s under partly to mostly sunny skies. Humidity levels, fortunately, shouldn't be too bad. A very weak cold front will pass through the area late, but won't result in a noticeable drop in temperatures. Overnight, it should be mostly clear, with lows 66-71 (suburbs-city).Pictured: Two officers and a horse take in some rays in Lafayette Square Saturday.

ThursdayMostly sunny and hot.
More hot air will stream in from the southwest. High temperatures should once again be in the low to mid 90s. The airmass will likely remain dry, with tolerable humidity. Overnight, look for partly cloudy skies ahead of an approaching front, with lows 68-73 (suburbs-city).
FridayWarm and breezy.
A cold front is likely to move through the region during the first half of the day, bringing mostly cloudy skies and possibly triggering a shower (20% chance or less). By afternoon, it should become partly sunny and breezy, with high temperatures in the upper 80s to near 90. Overnight, it's likely to be mostly clear with a light breeze, and cooler, with lows 60-65 (suburbs to city).
The WeekendEnjoyable warmth, low humidity.
Refreshing cool air should arrive in the wake of Friday's cold front. On Saturday, a mix of sun and clouds is likely, with highs 80-85. Saturday night should be very pleasant, with lows dipping down into the low 60s (even some 50s in the suburbs). Mostly sunny skies should be on tap Sunday, with low humidity and seasonably warm temperatures in the mid to upper 80s.
