It’s a very unusual situation developing in the Plains as a small but intense storm develops today through tonight. I am using the social media meteorological phase “Landcane” to explain this little but powerful storm.

The airmass across the Plains is warm and humid and that airmass will feed into the storm helping to produce a concentrated area of very intense rainfall and bands of thunderstorms.

Using the HRRR model as a guide to helping to pinpoint the area of heaviest rains, it appears that parts of Iowa and Nebraska will see over 6 inches of rain that could lead to dangerous flooding given the already soggy conditions. For example, Sioux, City, IA is already 163% of normal rainfall for the month of June. Any additional rain, especially what is shown on the model will cause extensive flooding. Flash flood watches are already out for much of Iowa into Nebraska.

Along with the rainfall, strong winds will occur with with gusts 30 mph to 50 mph behind the storm.

Thunderstorms, developing in bands, will produce sudden intense rainfall and strong winds across parts of Iowa, northern Missouri into Illinois. Some of the storms will be severe.

The storm peak in intensity Thursday morning then weaken some during the day as is loop around and heads southeast. Eventually the storm will bring rain to a wide area from the Ohio valley, Great Lakes to the Northeast Friday into the Weekend.

This one I found interesting because you don’t see the models trying to stir-up a small but intense little storm this time of the year, but yet, some of the operational models including the GFS are showing just that by Thursday morning. A small intense low pressure system with gusty winds, thunderstorms and heavy rain will form out of the severe weather that develops today. Once develop, so may say in resembles a “Landcane” which has become over of those social media weather terms that show up every now and then for a small intense storm.

In any case, severe weather explodes across the High Plains this afternoon and last into tonight . The storms will produce damaging hail, high winds and probably a few tornadoes. Certainly Storm Chaser weather for the High Plains.

The storms will form into an rather large area of thunderstorms overnight into Wednesday which be the seeding for low pressure to develop over Nebraska. That low pressure will deepen as the jet dips in and pulls into under the vortex. So by Thursday morning we should see a fairly intense little storm over the Plains.

The impacts will be gusty winds, heavy rains and thunderstorms wrapping around the storm. Winds may gust over 50 mph across parts of Nebraska, northern Kansas and perhaps Iowa.
