Forecast: More Heat at Summer's Summit

By Matt Rogers

Today is the meteorological midpoint of the summer season (defined as June through August) and once again there is more hot weather on the horizon. After a relatively cool morning today (especially in the 'burbs), we will be tracking a slow increase in temperatures for the coming days. We should see the lower humidity and upper 80s of today ratchet back up to the lower and middle 90s and higher humidities for the second half of this week. Thunderstorms are not far behind with more expected from Friday into the weekend.

TODAY (TUESDAY)

Comfortable morning with some slight afternoon heat increases. Mid to upper 80s. Mostly sunny skies are expected here today. After a low humidity morning, temperatures should ramp up faster today with highs edging back toward the mid to upper 80s. North to northeast winds will work to keep the humidity levels low through the day so the warmer high temperatures will still be fairly comfortable.

Mostly clear skies and temperatures dipping back down into the upper 60s in the city and lower 60s in the outer suburbs should be anticipated tonight. A nice summer night overall.

Keep reading for the forecast through the weekend. See UnitedCast for the outlook for tonight's game.

TOMORROW (WEDNESDAY)

Not that humid, but heat rebuilds. Highs in the lower 90s. Winds will be variable and the sun should be shining most of the time, but afternoon temperatures will nonetheless be moving back into the uncomfortable category. Look for highs in the lower 90s in most areas (perhaps slightly cooler north and west of city).

Relatively dry humidities should still allow temperatures to dip back down to the upper 60s in the suburbs and probably holding up near 70 in the city for Wednesday night.

A LOOK AHEAD

Thursday and Friday are setting up as the hottest days of this week with lower to middle 90s for highs and lower to middle 70s for lows. The humidity will be back up again so our heat indexes will be higher too. Clouds should still be in the minority on Thursday, but we could see a pick up on Friday afternoon with a 30% chance of a stray thunderstorm too. Confidence: High Thursday and Medium Friday

The weekend may take a bit of an edge off the heat, but there will be no break from the humidity. Look for highs in the lower 90s Saturday and the upper 80s on Sunday along with a daily 50% chance of thunderstorm activity, mainly in the afternoon and evenings. Once again, the models are grappling with the timing of a cold front Sunday which could finally vanquish the high humidity by late in the day. Confidence: Low
