Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 707 PM CDT Thu Sep 23 2021

SHORT TERM. 256 PM CDT

Through Friday night .

A vertically stacked storm system over eastern Lower Michigan has remained just far enough east of the area to keep the showers today over Lake Michigan and adjacent areas of Lake and Porter counties in IN. However, the Chicago metro area has been on the far western periphery of the large cloud shield associated with this system. This has resulted in a bit a temperature contrast across the area. Locations west of the city have seen a good deal of sun through the day, thus allowing their temperatures to climb into the upper 60s to around 70. However, places under the cloud shield, especially into northwestern IN are only in the upper 50s to the low 60s. The lingering showers over Porter county IN will dissipate later this afternoon and skies will clear area- wide, setting up a seasonably chilly night across the area. Expect low temperatures to fall into the 40s outside of the Chicago metro area.

On Friday winds will turn southwesterly and become rather gusty into the afternoon in response to a strengthening surface gradient in advance of an approaching cold frontal trough. Wind gusts are likely to gust up to 35 mph from the southwest during the afternoon and evening. A warmer airmass will filter into the area via these gusty winds, which will support highs area-wide reaching into the upper 70s on Friday afternoon.

Mild and breezy conditions will continue Friday evening as the front begins to shift into northwestern IL. The front will shift across all of northern IL by around, or shortly after midnight, then across my northwestern IN counties by 4 am. While low-level moisture will be rather sparse tomorrow, with surface dewpoints likely in the 40s, dewpoints look to pool a bit into the low to mid 50s along the frontal boundary Friday evening. Given the sharp mid-level trough with decent height falls aloft shifting overhead, the expectation continues to be that a period of showers with some embedded thunderstorms will develop with the frontal boundary. Severe weather is not anticipated, and any showers and storms should end from northwest to southeast following the frontal passage. Cooler temperatures will follow the frontal boundary into Saturday.

LONG TERM. 110 PM CDT

Saturday through Thursday .

A trend of pleasant and warming conditions through the weekend and into next week is expected.

The cold front that will bring us rain chances Friday night is expected to clear the area by Saturday morning as high pressure begins to move in and dry us out. Winds behind the front will be westerly at 10-15 MPH. Most of us on Saturday will see sunny conditions with the exception of a few clouds near the lake with afternoon highs in the lower 70s.

High pressure will continue to move east heading into Sunday which will turn our winds out of the south and transport warmer air northward to the Great Lakes. Winds will remain light through the period with speeds of 5 to 10 MPH. High temperatures Sunday through Thursday will reach the mid to upper 70s with some places possibly getting into the lower 80s. In addition to the warm temperatures, high pressure will keep us dry with no rain chances and mostly cloud-free skies with the exception of a few passing clouds from time to time.

FIRE WEATHER. 256 PM CDT

Southwest winds should quickly increase later Friday morning into the afternoon. Currently looks like a few hours of peak 20ft winds around 15-20 mph with higher gusts. Current forecasts for minimum afternoon RH values northwest of I-55 are between 30-40 percent, but it is worth noting that set-ups like Friday's forecast set-up can sometime see RH values dropping lower than forecast due to deep mixing and strong winds tapping into dry air above the surface. The 10-hour fuel stick moisture values should remain just above critical thresholds as well, so at this time it appears the threat of reaching red flag criteria is quite low. However, the strong winds, low RH, and antecedent dry conditions should result in a heightened (mainly grass) fire danger, particularly northwest of I-55 across northern Illinois.

AVIATION. For the 00Z TAFs .

A weak lake breeze has stalled in the vicinity of the Chicago terminals causing winds to veer to northerly and north- northeasterly for a time at MDW. The boundary could possibly bring a brief period of light NNE winds under 10kts to ORD over the next hour or two. Winds will then back to light westerly later this evening and will remain as such through the night. Winds will pick up through the morning and afternoon on Friday with SW winds gusting upwards of 25-30kts, primarily between 18Z and 02Z.

An approaching cold front will move through the area Friday evening and provide rain showers as early as 00Z with the highest probability for rain being closer to 03Z over the Chicago terminals. There also appears to be a non-zero chance for thunder Friday evening, however probability was deemed far too low to include in the TAF at this time. Winds will veer to NW with the passing of the front which appears to be around 03Z Saturday for both ORD and MDW. The front will also cause VFR ceilings to lower and thicken up through the day Friday with high MVFR conditions possible within the 03-05Z Saturday timeframe.
