no significant changes to the inherited forecast. shower chances
will persist through this evening as a series of weak short
waves traverse the flow aloft over the next 12 to 24 hours.
after a brief overnight lull, shower chances will increase again
late saturday morning through the afternoon with the passage of
a cold front. highest precipitation amounts ranging from 0.15 to
0.30 inch should remain focused mainly along and south of us-20.
seasonably cool temperatures will persist through the weekend w/
potential for frost across northern areas on sunday night and
monday night as temperatures drop into the upper 30s. /hammer
previous discussion (issued at 414 am edt fri may 8):
an anomalously cool pattern will persist as an upper low lingers
over eastern canada. 500 mb heights were around 400 meters below
normal from hudson bay into the upper great lakes. yesterday`s
temperatures were close to 10 degrees below normal. short wave
energy moving southeast in the cool pattern will generate showers
through saturday as the atmospheric environment remains saturated
or close to saturation from the surface to above 30,000 ft. another
in the series of these waves will bring scattered to numerous showers
to the forecast area today. there is above average of general model
agreement with timing and location of the showers this afternoon into
early tonight. the favored locations for rain will be south of the
michigan border.
this cool pattern will bring more chances for frost early next week.
temperatures are forecast to drop into the mid and upper 30s mainly
sunday night and monday night. vegetation development is likely
advanced for this time of year given the large number of growing
degree days (already near or exceeding 400 south of the michigan
border). headlines will likely be needed to cover low temperatures
these cold nights. /skipper

any remaining showers have now moved east to southeast from both
taf sites as the disturbance moves out of the area. periods of mvfr
cigs/vsbys overnight especially for kfwa, guidance does indicate
cigs at kfwa dropping briefly into ifr after 05z sat however
confidence is not high in this solution with the drier lower
levels, opted to bring it down to low mvfr cat in the taf. did
also mention thunderstorms in the area for kfwa for tomorrow
afternoon with the better convective conditions for the eastern
portions of the forecast area however exact locations/timing
still questionable.
