An upper ridge will hold over the Southwest from Fri/D4 into Sat/D5, but will begin to flatten as a progressive, low-amplitude wave moves into the far northern Rockies and Plains. This feature is then forecast to amplify across the Great Lakes and Northeast during the Sun/D6 to Tue/D8 period, while an upper ridge possibly re-builds over the Southwest. However, predictability becomes low for that pattern change. In association with the northern wave, low pressure with a trailing cold front may develop from the Plains to the Mid Atlantic from Sun/D6 into Mon/D7. Given the antecedent dry conditions, only marginal moisture return and destabilization are expected. While this may support scattered thunderstorms across the Ohio Valley region on Sunday/D6, substantial severe weather is not anticipated. Behind that system, a reinforcing high will likely spread south across the Plains and much of the East, resulting in stable conditions. ..Jewell.. 03/17/2026 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
