A front associated with the storm that delivered the rain this morning will cross the region this evening, marking the end to stormy weather for a while. A few scattered showers may accompany the frontal passage supported by a cold pool of air aloft, but otherwise this morning's precipitation will be the last for a long time.
Strong upper level confluence across the US/Canadian border will induce strong surface high pressure that will be in control of a large portion of the nation tomorrow. 1044mb high pressure will be located over Minnesota tomorrow morning, with the only precipitation in the entire CONUS over Texas. The responsible wave will flattened: unable to amplify and will weaken as it drifts across the southeast.
High pressure moves into the eastern US on Friday. Upstream pressures will continue to increase and drift east, south of New England through Saturday, keeping weak disturbances well to our south.
Thursday and Friday will feature picture perfect blue skies with temperatures on the cooler side - in the mid 30's. As high pressure shifts toward the east, a more southwesterly flow will develop, sending temperatures up into the 40's for the weekend.
Questions arise for next week, as the GFS and ECMWF start to disagree with the evolution of the next storm system out of the south. There continues to be potential for a large system affecting the east coast for the middle of next week.
