- There is a marginal risk of severe thunderstorms Sunday afternoon toward the Indiana and Ohio state line.

Issued at 248 PM EDT Fri Apr 12 2024

Wind gusts have just begun topping 40mph this afternoon, with Knox recording a 43mph gust. RAP forecast guidance suggests the surface low and low-level wind field may strengthen yet this evening.
Decreasing cloud cover can improve our mixing, but even so, upstream observations are closer to 40mph than 45-50 mph. So, will somewhat hesitantly let the wind advisory ride as-is. Rain showers have sprouted nicely off the lake and in the vicinity of vort max as seen on water vapor imagery. This diurnal activity will end around sunset; same for the showers noted across Wisconsin as of this writing.

Aside from a chance of thunderstorms Sunday, a beautiful weekend is on deck. A swirling upper-level low is replaced by high pressure centered over the Southeast US and a ridge aloft slowly builds.
Highs near 60 on Saturday (approaching 70 toward Monticello) give way to widespread 70s Sunday. However, a low streaking through the Great Lakes will send a weak cold front through in the afternoon.
This will result in plummeting temperatures lakeside as northwesterly wind sets in. This cold front could be the focus for isolated thunderstorms toward the IN-OH state line. Here, instability is marginal (near 500-1,000 j/kg), but dew points in the upper 50s and shear near 40-50 knots are appropriate for the highlighted marginal risk. Forecast soundings show a cap near 5,000 ft; something the cold front might overcome. I'll hold steady with only a 20% chance or so due to very limited coverage on forecast guidance.

This is a weak cold front indeed as high temperatures quickly rebound Monday back into the 70s. This, as 500mb heights rise in response to a deepening trough over the west. By midweek, a surface low moves through the Midwest bringing more rainfall and a risk of severe weather to Illinois and western Indiana. Forecast rainfall ranges notably at this time.

In the wake of this low, a second is quickly on its heels to end the week. This brings notably colder air to the region; a real bummer following a week in the 70s.

Issued at 115 PM EDT Fri Apr 12 2024

Ceilings are lifting and will continue to improve going into tonight, eventually giving way to clear skies by Saturday morning as the upper low lifts away to the northeast. There could still be a few lingering showers in the area, but confidence is low that they will impact the terminals so have not included in the forecast. The tight surface pressure gradients are of bigger concern with northwest winds gusting to around 35 kts this afternoon. They will diminish some overnight, but then pick back up during the day Saturday to 20-25 kts.
