Significant Severe Weather Event Possible for Wednesday, June 17th –

A shortwave trough will navigate the northern Plains and upper Midwest today with an initial round of strong thunderstorms to shift across the Midwest this morning.

In the wake of the morning wave, a warm front is forecast to extend from southeast Iowa through central Illinois which will become the focus for redevelopment later today.

If atmospheric recovery occurs, robust supercell development will be possible across the red shaded zone after 3pm with a risk for all severe hazards.

A high-end tornado threat extends from the Macomb/Galesburg, Illinois vicinity to central Illinois where a strengthening low-level jet will support the risk of intense tornadoes from 3-6pm.

Severe Storms and Heavy Rain for Wednesday, June 10th -

A cold front will continue to navigate eastward today with a risk of very large hail, damaging winds and isolated tornadoes. Adjustments have been made early this afternoon to reflect where highest confidence aligns.

An initial round of convection should continue to push northeastward from east Iowa through Wisconsin and Illinois capable of large hail and damaging wind gusts through early this afternoon.

Then a secondary round is forecast to develop by late afternoon with an initial threat for large hail over 2 inches in diameter and some tornado risk.

By this evening, a transition toward primarily damaging winds and spin-up tornadoes should occur as the main wave of convective activity shifts eastward across Wisconsin and Illinois.

Given the repeated rounds of storms and some training that may occur, scattered instances of flash flooding will be possible this evening with the most concentrated corridor over southeast Iowa to northeast Missouri.

Heat/Humidity to Trigger Renewed Severe Weather This Week –

Today:
A progressive cold front is forecast to spark an area of scattered to numerous severe thunderstorms beginning over the western Dakotas this afternoon and working eastward.

Initially, development should promote the threat of very large hail and some tornado risk before upscale growth occurs this evening with a transition toward primarily damaging winds.

Further south, a secondary area of interest extends from central NE to northwest Iowa, but uncertainty remains regarding severe development.

However, should storms be able to break the cap this evening, a highly unstable environment would support all severe risk hazards from the late evening into the overnight period.

Wednesday:
The cold front will slowly advance eastward, with a secondary area of heightened severe weather stretching from Minnesota/Wisconsin southward into Iowa.

While some uncertainty exists regarding the coverage/placement of the initial development due to overnight activity, some adjusting with the higher risk zone may be needed downstream.

Nonetheless, a focused risk for large hail over 2 inches in diameter, damaging winds potentially over 70 mph, and isolated tornadoes will be probable during the afternoon through the evening.

Strong Southwesterly Flow to Ignite Heavy Storms Sunday Through Monday –

Sunday/Monday:
The main impulse supporting scattered to widespread showers and thunderstorms is expected to track across Missouri and Iowa, with isolated activity extending into Illinois.

The primary wave of moisture will then eject eastward into Illinois Sunday night and into Monday, before exiting the region.

Rainfall amounts should be most appreciable from Missouri into the eastern half of Iowa, with scattered areas of 0.50-1.50” anticipated.

Severe Weather and Heavy Rains Tonight for Nebraska/Iowa –

A strong belt of southwesterly flow will trigger a secondary round of initial severe thunderstorms along a cold front beginning late this evening and extending through the overnight period.

While initial discrete activity will pose a severe threat capable of large hail and damaging winds, the primary focus will rapidly shift toward heavy rainfall over the course of the overnight period.

Given the increasingly saturated soil conditions across the region, particularly southwest/central Iowa, the high precipitation rates will elevate the risk for scattered instances of flash flooding.

Repeated Rounds of Severe Thunderstorms for the Plains –

Today/Tonight:
A cold front is forecast to trigger scattered severe thunderstorms this afternoon over parts of South Dakota supportive of large hail, damaging wind gusts of 60-65 mph, and a low-end tornado threat.

Elsewhere, secondary thunderstorm development is anticipated this afternoon and evening across parts of Kansas, Nebraska, and Iowa with an initial threat for isolated large hail.

Friday:
Eastern Nebraska through Iowa will become the primary focus for scattered severe storms beginning during the afternoon and extending through the evening.

While large hail and damaging winds will be the main hazards, some tornado threat is certainly possible given an increase in low-level shear profiles.

Severe Thunderstorms Possible for Sunday, May 31st –

A shortwave trough is forecast to eject eastward into the Midwest on Sunday, interacting with a sharp moisture gradient along the edge of an ongoing omega blocking pattern.

While overall storm coverage will be limited, initial forcing may trigger an area of isolated to widely scattered severe thunderstorms across the risk area.

A higher-confidence, more concentrated threat is more likely to materialize from eastern KS into central MO capable of large hail up to 1.00 inch in diameter and damaging gusts up to 65 mph.

Additionally, a localized, low-end tornado threat may evolve across portions of the risk area by Sunday afternoon and evening as low-level wind profiles strengthen.

Heat to Return Across the Midwest Late May/Early June –

The current active and cool pattern across the Midwest is expected to transition by late May, giving way to a significant warmup entering early June.

An upper-level ridge is forecast to develop over the Canadian Prairies and upper Midwest which will support a trend toward drier conditions and very warm temperatures.

As the ridge builds, the corridor of moisture and rain/storm risks will extend from the Rockies through the central/southern Plains and deep south.

There is the potential for an extended period of hot and dry conditions throughout the first two weeks of June which will be monitored closely for potential impacts during the extended period.

Impactful Severe Weather Expected for Monday, May 18th –

The initial wave of showers and storms from yesterday will continue to clear the region this morning in the wake of a second day of back-to-back heightened severe weather.

Scattered convective development is initially anticipated across northern KS after 3pm where a risk for very large hail, damaging winds and tornadoes (some strong) will be possible.

This activity will likely grow upscale this evening while shifting northeastward into Iowa with a risk for primarily damaging wind gusts (60-80 mph) and embedded tornadoes within the line.

The current forecast timeline places the most intense activity across northern KS/southeast NE roughly between 3-7pm, moving into southwest/central IA 6-10pm.
