the low pressure system that brought rain/snow to the area over the
past 24 hours has departed off to the northeast. any established
lake effect snow showers have diminished over the past few hours
although radar reflectivity still shows a few areas of light
returns, suggesting that flurries are still ongoing in spots this
afternoon. a tightening pressure gradient on the backside of the
still deepening low has allowed also for gusty west/northwest winds
to develop today. surface observations currently show gust around 25
mph and winds may occasionally gust as high as 30 mph through this
afternoon. gusty winds may allow for some blowing and drifting to
occur, especially on n-s oriented roads. as subsidence works in
this evening, winds and any lingering snow showers will
diminish.
while we do get a lull in precipitation in the next 24-36 hours,
reprieve from the active weather pattern, overcast skies, and windy
conditions will be hard to come by this upcoming week. high pressure
builds in across the mid mississippi valley to start the new work
week. on the periphery of the high, southwest winds may gust up to
20 to 25 mph on monday and tuesday. monday will be a dry day with
waa boosting highs near 40 degrees, allowing for melting of snow to
occur. there could be some intermittent sun and clouds in the
afternoon and evening tomorrow; enjoy this while it lasts because
the january permacloud returns for much of the week!
the next chance for rain/snow arrives tuesday afternoon through
wednesday with a low pressure system that traverses the upper great
lakes. precipitation is expected to start off as rain with high
temperatures in the mid to upper 40s tuesday. a cold front sweeps
through tuesday night and as temperatures fall, sounding profiles
favor a some snow mixing in tuesday night. caa and convergent low
level winds will also allow for a lake response; periods of lake
effect snow showers are anticipated to develop wednesday and
possibly linger into thursday. windy conditions develop once again
wednesday night into early thursday as a rather amplified upper
level trough pivots through and may become cutoff over the ohio
river valley. northwest winds could gust as high as 30 mph.
colder air follows for the end of the week into the weekend (highs
in the 20s and low 30s) with yet another system on the horizon.
better snow chances exist on friday and into the weekend with
the colder air, although there is a lot of uncertainty as to
exactly where this weekend system tracks. recent runs of the nbm
have a low tracking across the great lakes, which would mean
snow in our area. however, recent runs of the gfs and ecmwf have
a system lifting out of the south bringing the better snow
chances south of our forecast area and into the ohio river
valley. stay tuned!
