Near the tail end of the front, a slight risk of severe weather is advertised by the Storm Prediction Center for portions of New Mexico and west Texas today. Temperatures will soar ahead of the front; northern New York and interior New England should see another hot day on Tuesday, with high temperatures rising into the 90s once more, with record heat/warmth possible. For Wednesday, the heavy rain threat continues across southeast Texas near the stalled upper level disturbance/front combo across the Lone State State. In the wake of this feature, temperatures will cool across the southern Plains towards more average readings.

Some light rains are expected in association with the feature on Wednesday across the Northern Rockies before precipitation expands in coverage and intensity across the Northern Plains on Thursday as it taps moisture being lured northward across the Plains. In and near California to the south of the frontal intrusion and under the aegis of a warm core high, much above normal temperatures are expected and Heat Advisories are in place from southwestern Oregon into the central valleys of California; record high temperatures are possible in and near northern California.
