the surface, high pressure will dominate across the Gulf Coast
states and Eastern Seaboard. A moist airmass over south and central
Florida will result in weak instability by afternoon, where isolated

to central California ahead of an approaching upper-level trough. No
severe threat is expected across the continental United States
Monday and Monday night.
