Cold Front to Bring Welcome Relief to Area
But Unusally Warm, Dry Weather Lingers
Josh Larson @ 12:30 AM
We'll look for another very warm and humid day today, along with partly to mostly cloudy skies ahead of an approaching cold front which will bring a chance for showers and thunderstorms to the region for the second half of the day. Though we'll see more comfortable temperatures behind the cold front, they will still be somewhat above normal with drought-like conditions remaining.

Today
Cloudy, warm + humid. Expect some morning sun to give way to considerable cloudiness, along with warm and very humid conditions, ahead of the aforementioned cold front. High temperatures will be in the upper 80s. Scattered showers and thunderstorms may pop up from the early afternoon on, though the best chance for measurable rain is during the evening hours. Cloudy with a stray shower overnight and lows in the mid 60s.
More comfortable. Morning clouds should give way to at least partial afternoon sunshine along with noticeably less humid conditions and highs in the low 80s. (Note: the far southeastern suburbs may experience more cloudiness along with breezy conditions as coastal area of low pressure scoots by.) Mostly clear and pleasant Friday night with lows in the mid to upper 50s.
Delightful! In exchange for putting up with the very warm, sticky weather we've seen this week, we'll be granted a very nice weekend with high pressure firmly in control and very pleasant temperatures and humidity levels. Both Saturday and Sunday will feature abundant sunshine with high temperatures in the upper 70s and overnight lows ranging from the low to mid 50s across the coolest suburbs to near 60 downtown.Pattern Overview
While the cold front that will push through the area late today will bring welcome relief to both temperatures and humidity levels (and a lovely weekend to boot), even still, there are strong indications that the next week to ten days will continue to average noticeably warmer and drier than is usual for this time of year. One look at the CPC's 6-10 temperature forecast shows that computer model guidance is in good agreement for high probability of above-normal temperatures for next week. Our average high/low for next week is 73/55 and I'm thinking we'll average almost ten degrees warmer than that.
Pictured above: CPC's 6-10 day temperature forecast calls for a high (70% chance) of above-normal temperatures for next week.
Next week's forecast
Forecast highs/lows: 82/63 (normal = 73/55)
Forecast precip: Much below-normal
High pressure remaining firmly in control during the first half of next week will yield surprisingly-familiar conditions: warm and dry. Monday through Wednesday look to feature plenty of sunshine, with high temperatures probably in the low 80s with overnight lows from the mid to upper 50s across the coolest suburbs to the low 60s downtown. From this far vantage point, the forecast for Thursday and Friday is rather uncertain as a cold front may bring and increase in clouds and chance of rain. We'll call for mostly cloudy conditions both days with a 50/50 shot of scattered showers along with highs from 78-84 with overnight lows in the 60s.
