Overnight Sunday/Monday …
No Weather Hazards expected…
DISCUSSION…
Areas of drizzle possible overnight into Monday morning near the lake. Temperatures are expected to remain above freezing near Lake Michigan in Arlington Heights and the northwest suburbs Monday morning, but might hit 32°F in Arlington Heights and the northwest suburbs early Tuesday morning. Then morning lows will be well above freezing Wednesday morning and Thursday morning (Dec. 15). The normal lows for Dec. 12 through Dec. 15 are 21°F. The long range forecast doesn’t foresee a normal low (20°F) until Saturday morning (Dec. 17, 2022)
Expansive cloud cover and light northwesterly flow have held down temperatures below 40 for many areas of Chicagoland on Sunday resulting in another cloudy and cool day across Chicagoland. O’Hare did reach 40°F, however. Other than some patchy drizzle into far northeastern Porter County, the rest of the area should stayed precip free through the rest of Sunday afternoon and is expected to be precip free Sunday evening. Widespread cloud cover continuing overnight will again limit our cooling with temperatures remaining in the mid 30s in the Chicago metro and near the lake with lower 30s expected further inland.
As winds begin to trend more north and northeasterly this evening there is the potential for more drizzle to push inland off the lake after midnight tonight into portions of the Chicago metro, especially for areas nearest the lake. The drizzle may persist through the morning hours on Monday as well.

Key Message in the short term:
1. Areas of drizzle possible overnight into Monday AM near the lake (temps to remain above freezing in those locales)
Expansive cloud cover and light northwesterly flow have held down temperatures below 40 so far today making for another cloudy and cool day across Chicagoland. Other than some patchy drizzle into far northeastern Porter County, the rest of the area should stay precip free through the rest of the afternoon and evening. Widespread cloud cover continuing overnight will again limit our cooling with temperatures remaining in the mid 30s in the Chicago metro and near the lake with lower 30s expected further inland.
As winds begin to trend more north northeasterly this evening there is the potential for more drizzle to push inland off the lake after midnight tonight into portions of the Chicago metro, especially for areas nearest the lake. The drizzle may persist through the morning hours on Monday as well. Lake induced equilibrium levels are fairly shallow suggesting the majority of this is expected to be drizzle, but a few spotty showers cannot be ruled out. Will also note that the HRRR is the most bullish with QPF up to 0.05-0.10″ with this activity. Temperatures near the lake and where any precipitation falls are expected to remain above freezing. Accordingly the concern for any icing remains low. Further inland should remain mainly dry through the period, though some patchy drizzle cannot be ruled out Monday morning. Overall, tomorrow looks like a repeat of today with cool and cloudy conditions and highs in the upper 30s to around 40 degrees.
