374 FXUS63 KLOT 141708 AFDLOT Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 1208 PM CDT Sat Sep 14 2024 .KEY MESSAGES... - Outside of a small chance for a few showers west of I-39 this weekend, dry conditions and summer-like warmth will persist through at least next week. && .DISCUSSION... Issued at 145 AM CDT Sat Sep 14 2024 The models have continued to back away from the already low precip chances for this weekend. Other than a small chance of a shower early this morning across the southern cwa, have gone with a dry forecast for the entire area. There is a very small chance of a shower in the far southwest or western cwa, mainly this afternoon into early this evening but chances are too low to continue mention in the forecast. Dry weather is then expected through at least Friday night. Blended pops are in the slight chance range for next Saturday as some of the ensembles try to move a front into the area. With the possibility of a tropical system moving into the mid Atlantic by midweek, expect the entire pattern to slow with these pops likely overdone. No changes to the high temp forecasts which will be in the 80s through next weekend. The warmest days are expected to be Sunday and Monday with upper 80s expected for most areas with some locations reaching 90. Persistent easterly flow will continue through the entire period, which will keep temps cooler near Lake Michigan. cms && .AVIATION /18Z TAFS THROUGH 00Z MONDAY/... Issued at 1208 PM CDT Sat Sep 14 2024 No forecast concerns through the TAF period as high pressure will remain over the Great Lakes. East-southeast winds are expected to prevail through Sunday afternoon with speeds generally in the 5 to 10 kt range during the day and 4 to 5 kt range overnight. Though, a lake breeze will move through GYY this afternoon resulting in a more northeast wind direction. Otherwise, expect some SCT to BKN VFR cirrus to linger overhead through the period.
