FORECAST IN DETAIL
A big dip in the jet stream over the East assures a cooler than normal start to the work week. In addition, little waves in the atmosphere cycling through the region may ignite some afternoon/evening showers and thundershowers through Thursday. It’s more of an April or May-like pattern to start, but headed into the weekend, we dry out and more of a June-like pattern settles in.
Today (Monday): We should have a good deal of sunshine to start the day and refreshing 60s. But, with cold air at high altitudes, the sun will help to destabilize the atmosphere and clouds will build. I expect we’ll see some scattered showers and thundershowers (40-50% chance) develop, especially as a little wave in the atmosphere cycles into the region during the afternoon. Don’t be surprised - given the cold air aloft - to see some small hail in a few thundershowers. Highs are in the mid-70s. Winds from the northwest at 10-15 mph. Confidence: Medium-High
Tonight: Showers and thundershowers linger into the evening, but with the loss of daylight, they gradually diminish. Overnight, it’s partly to mostly cloudy with lows 52-57 (suburbs-city).. Confidence: Medium-High

Tomorrow (Tuesday): It’s very similar to Monday but the airmass is slightly cooler and I think we’ll have fewer showers (20-30% chance of rain). Any showers that develop are most likely during the afternoon. Highs range from the low-to-mid 70s with variably cloudy skies. Confidence: Medium
Tomorrow night: A very slight chance of evening showers with partly to mostly cloudy skies overnight. Clouds may interfere with the transit of Venus - but it’s a tough call at this point. We’ll keep you posted. Lows range from 52-57 (suburbs-city) Confidence: Medium-HighA LOOK AHEAD
Wednesday and Thursday closely resemble Monday and Tuesday with more sun favored in the morning and then clouds and scattered showers popping up in the afternoon and evening (30% chance or so of rain). Temperatures remain pleasant, with highs in the mid-70s, and overnight lows in the 50s. Confidence: Medium
Summer weather lovers will appreciate the forecast for Friday through the weekend: showers chances evaporate and we start a warming trend. All three days are partly to mostly sunny, with highs near 80 on Friday, 85 on Saturday, and perhaps 90 by Sunday. Overnight lows moderate from the 52-59 Friday morning to 54-63 Saturday morning, to 57-66 by Sunday morning (coolest readings in the north and west suburbs). Confidence: Medium
