PM Update: Showery & cool into tonight; more sun this weekend

The marine layer has really socked us in today, with clouds and showers holding high temperatures to around 60. It remains raw and showery through early to mid-evening before high pressure starts to take control and drying initiates. The weekend looks splendid with at least partial sunshine and pleasant temperatures.

Through Tonight: Spotty showers and drizzle are possible early on, but then partial clearing gradually takes place. We should eventually have some breaks in the cloud cover before patchy fog develops. Overnight lows range from 50-55 (suburbs-city).

The weekend: Both days are dry, but certainly not as warm as our recent Tuesday through Thursday stretch. We probably have clouds at times both days - but healthy doses of sunshine too. After some possible fog/low clouds early, highs Saturday reach the mid-70s while Sunday’s a bit cooler with highs near 70. Saturday night is partly cloudy, with lows 45-51 (suburbs-city). Winds are light, from the east and southeast.

Chicago heat: Even after the “pneumonia” back door cold front dropped temperatures 30+ degrees yesterday evening, they bounced right back as the front returned north today. Incredibly, the Windy City reached a record of 81 this afternoon - its 3rd straight 80+ day (and record high) - the most on record during March. More information at the Chicago Weather Center.

February global temperatures: It was the 22nd warmest February on record globally according to NOAA and 324th consecutive month with above average temperatures, but the coolest February since 2008 according to NOAA. For more information, see the State of the Climate monthly report.

Pollen update: As of this morning tree pollen was reported as HIGH at 212 grains/cubic meter. Grass pollen is back, MODERATE at 2.6 grains/cubic meter. Some of it, no doubt, got washed out by showers this afternoon.
