Weather Underground Forecast for Tuesday, June 14, 2016
Active weather will impact the central portion of the country on Tuesday, while a warm air mass settles in over the southern Plains.
A wave of low pressure will shift northeastward across the central Plains and the upper Mississippi Valley. This system, combined with warm and moist air from the Gulf of Mexico, will fuel strong to severe thunderstorms across the central third of the country. Severe thunderstorms will be possible in northeast Oklahoma, Kansas, eastern Nebraska, Missouri, Iowa, southeast South Dakota, southern Minnesota and western Illinois. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. In addition, heavy rain will bring threats of flash flooding to northeast Nebraska, eastern South Dakota, southeast North Dakota, Minnesota and northern Iowa. Showers and thunderstorms will also expand east southeastward across the Midwest, the Mid-Atlantic and the Deep South.
Scattered showers will stay in the forecast for northern New England as a low pressure system rotates over southeast Canada. Fairly cool air will also stay in place across New England due to this low pressure area.
Out west, a cold frontal boundary will stretch southwestward across the upper Intermountain West and the Great Basin. This frontal system will stall out, but will continue to generate scattered showers and thunderstorms in the Northwest. Most of these storms will be driven by daytime heating, so expect the bulk of storms to fire up during the second half of the day. High elevation snow will be possible in the Cascades and the northern Rockies due to cool air over the region.
A ridge of high pressure will bring afternoon temperatures into the triple digits across portions of the Four Corners and the southern Plains.
Temperatures in the Lower 48 states Monday have ranged from a morning low of 32 degrees at MCMWTC BRIDGEPORT, CA, Calif. to a high of 102 degrees at Pecos, Texas
