National Weather Service Chicago/Romeoville, IL
627 AM CDT Fri Apr 14 2023
.SHORT TERM… Issued at 314 AM CDT Fri Apr 14 2023
Another unseasonably warm day is in store today with high temperatures in the low 80s. While conditions will remain quite dry today, low-level moisture trends will become a bit more muddled as the day progresses. A compact low that lifted north from the Gulf of Mexico will advect a stream of Atlantic-sourced low-level moisture into the Ohio River Valley (a rather uncommon trajectory this far north and west outside of tropical systems). A gradual increase in mid-level clouds ahead of the low should slightly reduce mixing heights while low-level moistening limits the reservoir for drier air to mix to the surface. If the increase in moisture is more pronounced than currently expected, forecast RH values around the mid 20s may end up being too low. In fact, min RH values from guidance today produces a nearly 20% range from the low 20s to around 40%. While winds will be slightly lower than Thursday, some gusts over 20 mph, especially in the northwest CWA, will favor continued elevated fire spread concerns this afternoon.
By Saturday morning, additional low-level moisture from the Gulf of Mexico will begin filtering into the area, reducing the elevated/high fire risk from the past few days. Low/mid-level warming from an EML will cap the forecast area through most of the daytime hours, but with mid-level height falls beginning to spread over the area ahead of an approaching trough late in the day, an isolated storm or two may develop across the western CWA prior to sunset.
