.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)

Longwave trough slowly begins to shift east for the start of next
week. Below normal temperatures will continue on Sunday before a
slight warming trend on Monday/Tuesday. Even then, temperatures
will only be near to a few degrees above normal. Precipitation is
expected to remain north of the state. Northerly flow will return
to much of the area, but at this point, looks fairly light as
ridging struggles to take hold. CEO
