DISCUSSION
Issued at 335 PM EDT Tue Apr 16 2024

Impressive surge of low level moisture underway as 40 kt LLJ has remained in place all day, allowing for rapid advection of higher dewpoints into southern parts of the area (mid to upper 50). 60+ dewpoints were not far off to the south, but strong mixing behind the elevated warm front was keeping them in check touching 60 in a few spots. As expected the warm front has come through with little fanfare despite some elevated instability and occasionall agitated cu. One shower briefly popped up over Jay county a few hours ago and disspated within 10 minutes.
While slgt chc pops have been maintained for collaboration, main focus of shower/storm chances continues to take shape to our west and south with a line of storms from SE Iowa to west of St Louis on the main sfc warm front. The strong flow will help this propegate NE rather quickly, possibly reaching far western parts of the area near or shortly after 00Z. CAMs conitnue to struggle with what will be left of this band of storms as it enters, encountering a somewhat more stable environment with loss of heating and the best flow remaining to the west. While still somewhat skeptical on the overall setup, have maintained categorical pops mainly western half where last vestages of instability will exist. Some CAMs actually disspiate the first round and then quickly redevelop additonal storms behind it that expand as LLJ tries to ramp back up. Too many mesoscale challenges and scenerios to make radical changes so will defer to eve shift to monitor trends. Any precip should quickly exit the area by 9-12Z Wed with the entire area rooted in the warm sector of the system.

The main sfc low will be into NW Wisconsin by 12Z Wed with the initial pre-frontal trough/occluded front racing east during the morning hours. CAMs in general seem to agree that a narrow, broken line of storms will develop across western parts of Indiana roughly 14-15Z and then move east. SBCAPE will start on the lower side 500-1000 J/KG) but increase as pockets of heating occur ahead of the line for locations along and east of I-69.
Effective shear on the order of 35 to 40 kts will be sufficent to help organize the storms with large hail being the main threat. Inihibition from the overnight storms may limit the overall development with main area of focus likely to be into NW Ohio and points east during the afternoon. Slgt risk was generally maintained with the best tornado risk remaining in the NE part of the area. Once the line clears, precip will end with a dry forecast through Thursday.

The main upper low will track just along the US/Canadian border into Friday with the overall trough sending a cold front south into the area with chances for showers increasing, especially Thursday night. A few models seem to get rather agressive on bringing 60+ dewpoints back into SE areas, but given the limited time for the moisture to return not buying it at this point.
This should limit any thunder potential but still warrants a period of cat pops. Thereafter, we continue to trend colder with highs in the 50s and lows in the mid 30s to near 40 into the weekend. It does look like we begin to trend back towards or above normal next week but is likely short lived as additional waves drop south to bring more chances for showers.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/
Issued at 153 PM EDT Tue Apr 16 2024

Low level warm frontal feature could be a focal point for isolated shower and storm development this afternoon. With the bulk of forcing displaced well to the west across the Mid MS River Valley and Corn Belt this afternoon, will keep TAFs day through the late afternoon hours. By later this evening, large scale forcing will increase as upper diffluence shifts across the western Great Lakes and axis of low level jet also shifts across the Ohio Valley and southern Great Lakes. This evolution should create a likelihood of showers and storms in the 02Z-08Z timeframe. A lull in showers and thunderstorms is possible by daybreak Wednesday, but focus will then turn to cold frontal portion of occluding system. High resolution guidance is in fairly good agreement a broken line of showers and thunderstorms developing ahead of this frontal feature.
Convective initiation may be relatively early (~15Z-17Z) across NW Indiana/portions of north central IN). Associated upper vort lobe and cold front should be progressive across the area with thunderstorm threat exiting KFWA vicinity after 20Z. Have maintained MVFR cig mention overnight accompanying the better low level moisture convergence with the low level jet, but otherwise, VFR conditions are expected outside of any stronger showers and storms. Bulk of this period will also feature gusty southeast and south winds, with gusts as high as 25 to 30 knots.
