if you are looking for the warmer weather to return, hang in there
as the last of the cold air departs tonight as high pressure drifts
across the region and a southerly flow starts wednesday. before we
get there, we are looking at one more cold night with near/below
freezing temperatures expected. lows will likely occur during
the overnight hours, then become steady or slowly climb as mid
level clouds start to move in to limit radiational cooling.
an upper level low currently exiting se british columbia on course
to move into north dakota before eventually heading to north of lake
superior thursday. initially, the low will be responsible for a
dramatic warm up (15 to 25 degree increase) in highs compared
to today. a frontal boundary will make a run at the area wed
night into thu, with increasing moisture, but losing overall
dynamics as the upper support departs. slgt chc to chc pops are
maintained, highest in the nw. the boundary will stall out,
awaiting another wave that arrives thursday night into friday.
while pops and qpf are a bit higher with this feature, the
overall strength of the trough and glancing impact will limit
impacts. qpf will be highest in nw areas where a half to locally
three-quarters of an inch of rain may fall. a few storms will
be possible as well, but are expected to be more "general" in
nature.
the front will temporarily lower high temps friday across the area,
mainly in the nw where highs will only be in the 50s. a much
stronger surge of waa will commence starting saturday as sw winds
ramp up in response increasing upper level heights as a deep trough
digs into the western us. low level moisture will also increase with
a series of waves set to eject from the trough to bring better
chances for showers and thunderstorms. right now the axis of
heaviest precip looks to reside just nw of the area, but will need
to be monitored closely as any heavier qpf will have impacts to
already high water levels.
