Through Monday Night:

In sharp contrast to Saturday's weather, conditions are much cooler today following last nights cold frontal passage. This cooler weather is also be aided by filtered sunshine complements of a persistent broken deck of strato-cu, which continues to stream southeastward across the area in advance of the next approaching short wave impulse. These conditions are expected to persist the remainder of the day, with inland temperatures holding in the upper 70s to low 80s. Temperatures will be a few degrees cooler near the lakeshore.

Aside for a small chance of couple of light showers or sprinkles this evening across far northeastern sections of IL associated with a quick moving impulse swinging southeastward across southern Lake Michigan, the weather will remain dry tonight.
Decreasingly cloud cover and light winds under an area of high pressure will allow temperatures to drop back into the lower to mid 60s for overnight lows. These conditions may foster some patchy ground fog towards daybreak Monday morning, especially over some of the areas that received heavy rainfall last night.
However, significant areas of fog are not currently anticipated.

Monday will be another decently pleasant weather day as a mid- level short wave ridge shifts overnight. Conditions will be turning warmer again, however, as southerly winds return following the eastward departure of an area of high pressure.
Accordingly, inland temperatures are expected to top out in the mid to upper 80s under mostly sunny skies. However, another afternoon lake breeze will keep temperatures along the southern Lake Michigan shore several degrees cooler.

Locally, our weather is expected to remain quiet through Monday evening. However, later Monday night into Tuesday morning we will have to keep an eye on the potential for a developing and organizing MCS across the Upper Midwest to dive southeastward into our area along the eastern periphery of an MLCAPE gradient.
While questions remain on the evolution and timing of this potential MCS shifting into our area, there continues to be a signal for a period of stormy weather near our area into early Tuesday. Gusty winds, potentially near severe levels (58 mph), and locally heavy rainfall would be possible with any organized MCS that dives southeastward into the area through early Tuesday morning.


Tuesday through Sunday:

Primary forecast concern and challenge is the potential for thunderstorms Tuesday and Tuesday night and their impact on high temps/heat index values Tuesday afternoon. There remains quite a bit of uncertainty with the potential for ongoing convection Tuesday morning. Just about all of the models show convection developing to our north Monday night, but then quite a spread in how it evolves and where it moves by Tuesday morning, with some consensus it could be over southern Lake Michigan into southwest lower MI and northern IN. Even lower confidence for the potential for strong/severe weather during this period. But if an organized line can reach the area, some damaging wind potential will be possible, along with heavy rainfall.

If storms do not materialize Tuesday morning, high temps will likely reach the lower 90s and possibly mid 90s. Coupled with dewpoints in the lower 70s, heat index values in the 100 to 105 range will be possible. If storms do reach parts of the area Tuesday morning, they will likely weaken/dissipate through the morning, allowing for the potential for temps to recover to the lower 90s. From this distance, however, confidence is low for high temps, dewpoints and associated heat index values. Winds on Tuesday also have the potential to gust into the 30-35 mph range, if there are several hours of precip free-warming.

By afternoon, a cold front will be approaching and thunderstorm chances will be increasing. Already outlooked for a level 2 of 5 for Tuesday and wherever storms develop, they will likely be severe. Though morning convection could have impacts on where convection forms later in the day and thus low confidence for location. In addition to the severe potential, pooling dewpoints in the lower/mid 70s will help push precipitable water values into the 2+ inch range with heavy rainfall also possible. Given the heavy rains that fell across parts of northern IL last night, flash flooding could be more of concern over a wider area. There may be some lingering showers or thunderstorms Wednesday morning across the south, but a cold front will move south of the area by Wednesday morning, ending the chance for precipitation.

Cooler and drier air will spread across the region Wednesday night into Thursday. Low temps by Thursday morning may be in the 50s across most areas. Northerly winds will increase across Lake Michigan Wednesday into Wednesday night. A little early to tell exactly how strong the winds will be, but the potential for high waves and dangerous swimming conditions at Lake Michigan beaches will need to be monitored with later forecasts.

The pattern quickly shifts back to southerly flow Thursday night and there will be increasing chances for showers and thunderstorms by Friday morning, likely in a decaying phase from earlier activity further west of the local area. A cold front will then move across the area Friday night with a period of showers and thunderstorms possible. High temps on Friday also tricky, depending on the amount of cloud cover/precip earlier in the day and the amount of recovery before additional convection later in the day.

This cold front currently looks to be fairly progressive and possibly southeast of the area by Saturday morning. Blended pops on Saturday are likely too high and with high pressure moving across the region, next weekend may end up being dry both days with highs near normal and less humid conditions. cms

Forecast concerns for the terminals...

- Lake breeze turning winds easterly at the Chicago sites early Monday afternoon

Overall VFR conditions are expected this evening as diurnal cumulus continues to fade with sunset. However, pockets of 2000 to 2500 ft clouds may persist into northwest IN this evening as an area of clouds over southern Lake Michigan moves onshore.
Though the bulk of these clouds should remain east of GYY.
Otherwise, expect winds to ease this evening with directions holding in a northwest fashion through the night.

Heading into Monday, winds at the inland terminals (DPA and RFD) will settle into a south-southwesterly direction with speeds remaining in the 5 to 10 kt range. However, a hybrid lake breeze/synoptic wind shift is expected to occur at the Chicago terminals and GYY between 15z and 18z Monday. Given how tricky these lake breezes can be to forecast 24 hours out I generally maintained the prevailing easterly wind shift around 16z at GYY and 17z at ORD and MDW, but shifts in timing may occur with future updates. Once winds at the Chicago terminals become easterly they are expected to remain as such through the rest of the period with otherwise VFR conditions areawide.
