.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Issued at 215 PM CDT Sun Sep 28 2025
Monday night through Saturday
Assessment...A near certainty (>99%)of above normal temperatures
and no rain.
The thermal ridge remains in place across the area through mid-week
before slowly retrograding into the Plains. Record highs are not
expected for Tuesday but have been included in the climate section.
The main weather players this week will be the developing blocking
pattern on the east coast with strong high pressure from New England
into the mid-Atlantic states with tropical systems Humberto and
Imelda off the southeast coast. Until a developing trof forecast by
the global models develops on the east coast to push Humberto and
Imelda out to sea, weather systems across the CONUS will slow to a
crawl. The persistent dry air over the area will also result in cool
nights and warm days.
Saturday night and Sunday
Assessment...Very high (>90%) confidence on warmer than normal
temperatures continuing. Very low (
