US Hazards for Monday, April 17, 2017US HazardsAssess Your Weather Risk

Strong to Severe Thunderstorms Possible Monday across the High Plains
An area of low pressure over the Oregon/Idaho border will progress eastward across the Rockies today, bringing a potential for strong to severe thunderstorms to the region. Moderate instability and strong shear should be present, allowing for the potential for supercell thunderstorms capable of large hail, damaging winds, and tornadoes.

Major Cities in Region: Goodland, KS

Region 1 Monday, April 17, 2017Region 1

Thunderstorm Potential for South Texas on Monday
A line of thunderstorm activity moving toward the Texas coastline will continue to have the potential to produce severe weather through the day before  moving out of the region by early evening. Stronger storms may produce hail and/or damaging winds.

Major Cities in Region: Laredo, TX, Corpus Christi, TX, Brownsville, TX

Region 2 Monday, April 17, 2017Region 2

Development of Thunderstorms Across Central Plains into Mid-Missouri Valley on Tuesday
A cold front dropping southeastward out of the Northern Plains on Tuesday will provide a focus for thunderstorm development during the afternoon and evening hours across southwestern Iowa and northwestern Missouri. A few thunderstorms may produce gusty winds and hail. Later in the evening and into the overnight hours, more widespread thunderstorm development is expected across the Central Plains as an area of low pressure intensifies. A strengthening low level jet will allow for strong to severe thunderstorms in this region. Large hail will be the primary hazard with any storms in this region, but gusty winds will also be possible as storms become more organized.

Thunderstorms Wednesday from Central Plains to Great Lakes
An area of low pressure and cold front will track eastward across the Great Plains and into the Midwest on Wednesday. Scattered thunderstorms are anticipated by the afternoon in the Mid-Mississippi Valley and southwestern Great Lakes. Further west across the Plains, thunderstorms are expected to be more isolated and likely developing a bit later. Any thunderstorms that develop will have the potential for large hail, damaging winds, and a few tornadoes.

A Look Ahead
An intensifying upper level trough will move across the Central Plains on Friday. This will allow for the development of an area of low pressure. To the south of the low, a cold front and dryline will provide a focus for the development of thunderstorms. Further north, a warm front across the Central Plains will allow for the potential for heavy rain across portions of the Central Plains. Rainfall accumulations of 1-3 inches with isolated higher amounts in excess of 4 inches are expected. This may lead to an increased risk of flooding or flash flooding.
