Medium-range guidance continues to indicate that the prevailing split flow will evolve in a manner that maintains a broadly confluent regime across and east of the Rockies through this period. Within the northern branch, it appears that a fairly significant low will form within broad troughing overspreading the Northeast by early next weekend, perhaps trailed by another developing low across parts of the Upper Midwest/Great Lakes by early next week. At the same time, an initially prominent subtropical high centered over southern Mexico is forecast to become suppressed, as a mid/upper low emanating from the subtropical eastern Pacific is forced eastward into and through the confluent regime across the southern tier of the United States. It still appears that the shearing subtropical impulse, and perhaps a trailing perturbation, will be preceded by broad cool surface ridging overspreading much of the central and eastern U.S., as far south as the Gulf Coast region by Thursday. The frontal zone on the leading edge of this air mass is generally forecast to progress into the Gulf Basin and Florida Peninsula, where it is likely to linger through early next week. While forcing for ascent and destabilization might support increasing thunderstorm development across parts of central and southern Texas late this work week (mostly above/to the cool side of the stalling frontal zone) into Florida and adjacent portions of the Southeast by late next weekend, the risk for severe weather still appears relatively minor at this time. ..Kerr.. 04/27/2026 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
