Watch the 2018 Hurricane Season Forecast

Thunderstorms for the Northern Plains on Thursday
Strong surface heating and plentiful moisture will create enough instability for the development of isolated thunderstorms across the Northern Plains on Thursday, some of which could be supercells. This activity is forecast to move eastward into the evening hours before evolving into one or two complexes. Large hail, damaging winds, and tornadoes will all be potential hazards. Storms will continue to move eastward through the overnight hours.

Thunderstorm Risk for Thursday, June 14, 2018Thunderstorm Risk for Thursday

Risk for Excessive Rainfall through Saturday for the Northern Plains and Upper Midwest
Multiple rounds of showers and thunderstorms moving across the Northern Plains and Upper Midwest over the next three days will bring the potential for heavy to excessive rainfall. Each day, rainfall amounts will range 0.50-1.50 inch with locally higher amounts. Three day rainfall totals will range 1.50-4.50 inches with locally higher amounts. This will result in the potential for flooding and flash flooding across the area.

Thunderstorm Potential for the Upper Midwest and Central Plains Friday
Remnant clusters of thunderstorms will likely be ongoing across portions of the Upper Midwest Friday morning. Warm air moving northward may aid in additional thunderstorm development during the late morning, with damaging winds and hail the primary impacts. Outflow boundaries from the morning storms may allow for another round of storms during the evening with the main hazards being large hail and damaging winds. Further west across the Central Plains, a few supercells may  develop along a stalled front by Friday afternoon. Damaging winds and large hail will be the primary hazards with these storms.

On Friday, rainfall amounts will range 0.25-0.50 inch with locally higher amounts. Into Saturday, rainfall amounts of 0.50-1.50 inch are forecast.

Rainfall Accumulation for June 15-16, 2018Rainfall Accumulation for Friday and Saturday

Risk for Thunderstorms for the Central Plains and Upper Midwest on Saturday
Strong daytime heating and plentiful moisture will allow for the development of thunderstorms ahead of a cold front on Saturday. Clusters of thunderstorms are expected to develop and move northeastward along the front. Damaging winds, large hail, and tornadoes will all be potential hazards with these storms.

SPC Convective Outlook for Saturday, June 16, 2018SPC Convective Outlook for Saturday

Potential for Excessive Rainfall Saturday across the Northern Rockies
Moisture moving in from the Northern Plains combined with the remnants of Tropical Storm Bud will bring the threat of heavy to excessive rainfall to the area on Saturday. Because this region has relatively wet soils from previous rainfall, flooding and flash flooding will be a concern. Rainfall totals will range 1-2 inches with locally higher amounts.

Tropical Update
An area of low pressure located over the Yucatan Peninsula is producing disorganized showers and thunderstorms. This activity is expected to move west-northwestward across the Yucatan Peninsula and over the southwestern Gulf of Mexico through Saturday. Development, if any, should be slow to occur due to strong upper level winds.

A Look Ahead
Showers and thunderstorms will continue across the Northern Plains and Upper Midwest Sunday into Monday along and ahead of a cold front.

By Monday afternoon and evening, showers and thunderstorms will extend from the Great Lakes into the Southern Plains.  On Tuesday, showers and thunderstorms are forecast from the Ohio Valley into the Southern Plains. An area of low pressure may develop across the Southern High Plains on Wednesday, bringing a potential for showers and thunderstorms.
