LONG TERM [Sunday Night through next Thursday]...
A low-amplitude pattern is forecast to be in place to start the
extended period and continue into early next week across the
CONUS. This will keep the weather dry through early Tuesday. With
heights relatively high, temperatures will be above normal, with
highs in the mid 70s and lows in the low 50s.
By Tuesday, a trough of modest amplitude will move into the eastern
states and push a cold front towards the northern gulf coast. This
front should provide a chance of rain late Tuesday into Wednesday,
with a slightly cooler and drier airmass moving into the region for
late Wednesday into Thursday. The progressive nature of the upper
pattern should keep any significantly colder air well to the north.
