Forecast Overview:

Tonight – Friday: Mild temperatures will return again tomorrow, although the warm spell ended up slightly less warm than expected, which will be discussed in more details tomorrow. High temperatures on Friday will be similar to those of today, in the upper 70s to low 80s.

Saturday – Monday: A mainly dry cold front will come through late on Friday night with isolated showers/storms expected, followed by clearing skies on Saturday with highs in the low to mid 70s across the area. Overnight lows will drop into the mid to upper 40s for interior areas with mainly clear skies and the low to mid 50s for the rest of the area except for NYC, with lows in the mid to upper 50s. Highs on Sunday will be at least 1-2 degrees colder than Saturday’s highs, with overnight lows slightly warmer than those of Saturday night. Clouds will increase on Monday with highs in the low to mid 70s across the area.

Monday Night – Beyond: A widespread rain event is expected for Tuesday into early Wednesday. Rain will develop in the overnight hours on Monday, lasting occasionally throughout the day on Tuesday and Tuesday night with highs likely again in the low to mid 70s for most of the area. Rain will continue into the overnight hours before ending early on Wednesday, with less cloud cover later into Wednesday along with similar temperatures. A cooler air mass will briefly move in with slightly cooler temperatures into Thursday, but the trough axis will remain over the central US, with any prolonged stretch of dry and cool weather failing to move into the region as temperatures are likely to generally stay in the 70s.

      There will be occasional showers/thunderstorms throughout the day, with an increasing probability by the afternoon and evening, which may end up affecting your flight. Some strong storms may be possible but not to the extent of last Saturday. Weather in Chicago should be fine.
