1AM Day 3 Convective Outlook for Tuesday, February 24. NO THUNDERSTORM AREAS FORECAST
SUMMARY
Thunderstorms are not expected across the United States.
Discussion
The upper-air pattern will deamplify somewhat on Tuesday as a mid-level trough moving onshore in the Pacific Northwest helps break down the western ridge. The result should be broad northwest flow across much of the US. At the surface, in response to this northwest flow, troughing will develop in the lee of nearly the entirety of the US Rocky Mountains. Southerly winds to the east of this trough will begin drawing moisture northward into the Southern Plains.
Given the limited moisture across the central and eastern US, and the saturated, instability deprived forecast soundings associated with the expected moist, onshore/upslope flow across California, thunderstorms are currently not anticipated on Tuesday.
