The last vestiges of the recent very wet pattern across portions of the eastern U.S. will linger across northern New England tonight into Tuesday before exiting Tuesday night. In the wake of this precipitation---a cold front will sweep southeastward from the Upper Mississippi Valley---across the Great Lakes tonight and then southeastward into the Northeast Tuesday and Wednesday. This front will keep temperatures below average over the next few days from the Great Lakes into the Mid-Atlantic and New England. The western extent of the frontal boundary moving into the northeast over the next few days will stretch from the Upper Mississippi Valley---westward across the Northern Plains and into the Northern Rockies. This portion of the front will be a focus for potentially severe thunderstorms and locally heavy rains over the next few days across portions of the Northern to Central Plains toward the Upper Mississippi Valley. Numerous thunderstorms also possible tonight into Tuesday/Wednesday along a frontal boundary forecast to stretch from north Texas---east southeastward into the Lower Mississippi Valley/Central Gulf Coastal region. Locally heavy rains are possible across these regions. While below average temperatures are expected across the northeast quarter of the nation over the next few days---the opposite will be true over a larger portion of the country from the Great Basin/Rockies into the Plains. Widespread regions of temperatures in the 90s expected over the next few days---with temperatures near 100 possible Tuesday over Central to Western South Dakota/far northwest Nebraska..100+ degrees from Western Texas into eastern New Mexico and across southwest Arizona---southern Nevada and southeast California. 100 degree plus temperatures Wednesday likely across portions of the Southwest from Southeast California---Southern Nevada and southern Arizona and across the Southern High Plains from West and Southwest Texas into eastern New Mexico.
