A weak convergent boundary is noted on radar mosaic and surface obs just to our northwest this morning. This front is associated with an upper low crossing Hudson Bay and is becoming increasingly diffuse as the parent forcing zips east and strong mid/upper ridge holds over the Ohio Valley. No rain is expected locally, just a steady stream of high clouds given incredibly dry and stable low levels. Our area does see a wind shift later today into tonight to NNE and eventually east. Will have to keep an eye on fog potential given return of Lake Erie contribution but ample high clouds may limit development as is occurring now. Highs today still reach low 70s ahead of the front and flow veers back to a more southerly direction by Tue afternoon so highs on Tue are still around 70 (slightly cooler far NE).

S/SW flow and warm/moist air advection ramp up again Tue night through Thu as another front take aims at the region. A more southward track of the parent trough and a much better prefrontal LLJ/theta-e surge suggest at least some chances for rain on Thu. The trough is still well to the north though and local areas remain relatively dry and stable. Best chances for some light rain will be in our far NW Thu afternoon. Latest NBM even throws in a chance for thunder in our NW but not expecting anything significant and areas along/south of US-24 likely remain dry. Highs do climb near 80 on Thu, which is the record (set in 2024).

Upper ridge finally breaks down this weekend with potential for a southern stream trough to tap into better moisture and bring our best chances for rain in a while. Still a ton of spread regarding the timing and evolution though. Halloween still looks mostly dry but NBM is maintaining some slight chance PoPs. Better chances arrive Sunday into Monday but confidence on timing and amounts couldn't be much lower.

A weak cold front is seeping into far northwest Indiana this afternoon. Through time, this will allow winds to veer and become northeasterly tonight, followed by southeasterly Tuesday. No rain is expected with this front. Marine fog from Lake Michigan will be monitored this afternoon, but this is so far seeping southwest. Tonight, we'll monitor for any marine fog from Lake Erie (low confidence).
