Yes it looks depressing next week...again!
LONG TERM /SUNDAY THROUGH WEDNESDAY/...
If you squint really hard at the upper air charts for Sunday,
you might be able to convince yourself that upper level flow is
becoming slightly less trough-y, but that`s probably just
wishful thinking. We are growing less optimistic to see any
marked improvement before Monday. The recent blocking pattern
has proven to be rather persistent and in no hurry to unravel.
The cyclonic flow and cool temps aloft should translate into a
good deal of cloud cover with POPs peaking during the afternoon
hours coincident with diurnal heating.
Precip probs should bottom on Monday before ramping higher into
Tuesday-Wednesday. Models are coming into better agreement in
tracking the southern stream wave farther to the north. There
are even signs that the briefly split-stream flow will try to
close off into another upper low in the Great Lakes/Ohio Valley
region by the middle of next week. So it appears the cool and
wet pattern will continue into the end of the month with no
signs of summer weather on the horizon (meteorological summer
begins on June 1).
