Talk about irony -- the fall-like weather
we've enjoyed the past few days gives way to summertime heat and
humidity, just in time for the start of Meteorological Fall!
Conditions today were still on the cool side, with overnight lows in the low 50s, even in the 40s in some spots. The afternoon highs running 5 degrees below normal in the upper 70s and low 80s. But this fall like trend is about to break, as southerly winds and overall warmer air builds in this weekend and beyond.
Before jumping into the forecast details, it's worth noting the hazy skies this afternoon. Massive wildfire in the northwest United States continue to rage and spill smoke and haze into the atmosphere which gets picked up by the jetstream and spilled downwind. The haze has finally made it into Illinois today, so skies are milky white as opposed to the deep blue we've had this week. These conditions may persist next week, but we'll be far from true "smoky" conditions as these particles should stay in the upper atmosphere and have little chance to reach back down to the ground.
Southerly winds will drive warmer and more humid air into the Midwest tomorrow, increasing temperatures to near average values for the weekend. Then we watch for a disturbance coming out of the central Rockies and croassing the central plains Friday for our rain chances. The track of this system, and the majority of the rain, will be into Iowa through northern Illinois and southern Wisconsin. The absolute earliest we could get a stray shower or storm would be Friday evening, but that seems highly unlikely. The best chance for rain will be Saturday morning and then taper off at some point in the afternoon. The end timing is proving to be tricky as the cold front associated with this system does stall out before reaching central Illinois, so it'll depend when the moisture plume passes along the front will mark the end of rain chances.
For all of next week, conditions will be dry and hot. Temperatures will likely be above average in the upper 80s and low 90s for the first 10 days of September. Next week is anticipated to be dry, but long range outlooks will try to replenish rain gauges the following week, so stay tuned for that.
THE 7-DAY TEMPERATURE OUTLOOK:
will be in the mid 80s Friday and Saturday; upper 80s Sunday and Monday; and, low 90s Tuesday through Thursday.
Overnight lows will
drop to the upper 50s
Thursday night; and, mid to upper 60s Friday through Wednesday night.
