After a mostly refreshing weekend, the heat and humidity will quickly emerge back on the scene today. The sultry air may help trigger some afternoon and evening thunderstorm activity through Thursday. Early Friday, a cold front should cool it off and dry it out by the weekend.
TodayWarm and humid.
A moist tropical airmass will begin building into the region today. High temperatures will take aim at the upper 80s and humidity levels will be noticeably higher than the weekend -- with the heat index around 90. Isolated thunderstorms with heavy rain could form late in the day but odds of experiencing them are less than 1/3. Overnight, we won't get much relief from the muggy conditions -- with lows near 70 downtown, and the mid 60s in the suburbs.

TuesdayVery warm, humid.
The weather tomorrow will be exactly like today except a bit warmer and more humid. High temperatures should reach 90 in many areas and the heat index will likely reach the low to mid 90s. PM T'storm chances will remain around 30%. Overnight lows will be on the warm side -- ranging from the upper 60s to low 70s (suburbs-city).
WednesdayHot and very humid.
The heat and humidity will probably reach a pinnacle for the week Wednesday. High temperatures will range from the low to mid 90s with the heat index in the upper 90s. A stray afternoon or evening thunderstorm could cool things off briefly but the oppressive airmass will hang around for at least one more day. Overnight, it will be on the sultry side, with lows in the upper 60s to low 70s.
ThursdaySticky then Stormy?
A cold front will likely approach the area, triggering late afternoon and evening thunderstorms. It's too early to be confident about the prospect of severe weather, but if I had to guess which day had the best chance of strong or severe storms, I'd say Thursday. Before any storms affect the area, we'll have one more warm and humid afternoon with highs in the low 90s. Overnight, showers and storms could continue as the front slowly passes through the region with lows around 70.
FridayLingering showers? Clearing?
Thursday night's cold front should pass to the south allowing for gradual clearing Friday. However, there's some chance it could be slow to clear the region or not clear the region at all -- so I'll call for a 40% chance of showers and t'storms in the morning and a 20% chance in the afternoon and evening. High temperatures will probably be in the mid 80s. Overnight, if skies haven't already cleared earlier, they should by morning as much dryer air filters in from the northwest. Low temperatures should range from 60-65.
The WeekendComfortably warm, low humidity.
Cool Canadian high pressure should build into the region making for a mostly sunny, refreshing and beautiful weekend. High temperatures should range from 80-85 degrees both days, with enjoyable overnight lows in the upper 50s to low 60s (suburbs-city).
