Area Forecast Discussion National Weather Service Northern Indiana 626 AM EDT Sun Jul 25 2021

SYNOPSIS. Issued at 305 AM EDT Sun Jul 25 2021

Patchy fog along and north of the Toll Road will dissipate quickly after sunrise Otherwise. dry and less humid conditions are expected through Tuesday but highs will still climb to around 90. Humidity returns on Wednesday with the next chance of storms sometime Wednesday night or Thursday. Cooler weather finally returns for the end of the week.

SHORT TERM. (Today and Tonight) Issued at 305 AM EDT Sun Jul 25 2021

Quiet weather expected for the next few days as subsidence/high pressure settles across the region. Some patchy fog across our northern zones but high clouds keeping this in check for our area and will dissipate quickly after sunrise. No plans for an advisory at this time as visibilities in our area have been highly variable. Isolated convection in our SE will continue to push SE and dissipate through the early morning as much drier air advects into the area. Wouldn't completely discount a stray shower in our far south later today but certainly not worth a mentionable PoP. While incoming airmass is much drier it is not much cooler with 850mb temps only a degree or two cooler than yesterday. This will be more than offset by increased mixing and more sun, particularly in our northern half and during the afternoon. Held with previous warm lean and have highs around 90F. Thankfully dewpoints will tank during afternoon mixing (mid 60s south and 50s in our NW). This will keep heat indices in check (only mid 90s in S/SE zones). Lows tonight drop into the low/mid 60s. Some potential for isolated pockets of ground fog but suspect near-surface moisture will be sufficiently stripped away by then to prevent anything impactful. Will hold off on mentioning anything for now.

LONG TERM. (Monday through Saturday) Issued at 305 AM EDT Sun Jul 25 2021

First half of the week still appears dry as low level ridge remains anchored over the Ohio Valley. Thermal ridge remains in place as well and expect highs to remain around 90 under mostly sunny skies. Dewpoints remain low through Tue with heat indices not much different than actual temps. That does begin to change Wed with a little better moisture return as westerly flow ramps up. 850mb temps also climb a degree or two and we could see heat indices approach 100F on this day. A very weak backdoor front does try to push into our northern zones Tue night but forcing and moisture/instability are very weak and will hold with silent 10 PoP for now. Better precip chances still look to be sometime Wed night/Thu as a stronger upper jet and associated shortwave dig into the Great Lakes sending a healthy cold front through our area. Exact timing and associated impacts still uncertain at this time range but do expect a round of storms at some point in this window. Cooler and drier conditions then return to finish out the week.

AVIATION. (For the 12Z TAFS through 12Z Monday Morning) Issued at 620 AM EDT Sun Jul 25 2021

The surface trough has settling south of the terminals, and with weak flow and residual low level moisture behind this boundary, fog and stratus have developed. LIFR fog will persist at SBN through sunrise. FWA is currently only seeing stratus, since radiational cooling is being limited by the lingering cirrus shield from earlier convection, but fog may move in as the higher clouds advect south. After sunrise, daytime heating will allow this trapped moisture to mix out, and mainly high clouds can be expected. Quiet weather returns for the day with northwest winds around 10 mph and VFR conditions.
