Long term /Wednesday night through Sunday/...
the long term period begins Wednesday night with the expectation
of above normal temperatures. There is some uncertainty with the
details of precipitation. Plenty of Pacific moisture will swish across
the Continental U.S. And an upper level ridge will briefly build over the
eastern part of the nation around Friday and Saturday.

A cold front and associated short wave move off to the southeast
Wednesday night with any showers ending that evening. Dry
weather is expected Thursday into early Friday. A short wave may
bring a few showers Friday and Friday night especially southern
portions with probability of precipitation set no higher than 30 percent. During the
weekend...a complex low pressure system and cutoff upper level
low develop in the plains states. Precipitation associated with this
system should stay to the west through Sunday.

Fairly consistent day to day temperatures are expected Thursday
through Sunday with highs in the 50s and lows in the mid 30s to
lower 40s.
