weekend. Blended solution compromise may be tad fast.

Friday...the period starts with warm ridge overhead that shifts
to the east coast Saturday. A large upper trough coming ashore
in the Pacific NW Friday will advance quickly across the Rockies
and into the Great Lakes and Ohio Valley by Sunday. Models
continue to differ on timing of rain with this trough. This
weekend`s system appears similar to last weekends which was
best handled by faster arrival of rains Sunday seems

Sundays rain producing trough continues to fill as it exits
Sunday night but it is followed by a further intensification
and deepening of the mid latitude trough over our region late
Monday into Tuesday. The upshot of this will be a brief dry
period Monday before a return to showery weather Tuesday.

Temperature blends appeared pretty good and were followed. This
period will be characterized by a shift from well above normal
temperatures Friday into Sunday back nearer to normal Monday and
below normal Tuesday with max temperatures Tuesday remaining in
the 50s.
