System should pass Tuesday morning with a few showers after a mostly cloudy to cloudy day today. Highs today will run 41-46.
After cloudy skies turn to some potential PM clearing, highs of 46-53 are likely. Winds should run west-southwest at 10-25 mph.
With a clearing sky tomorrow night & diminishing wind, lows of 28-31 are likely.
Clouds should quickly overspread the area early Wednesday morning & some scattered rain should follow. Some areas may still be at 31-32 as some of these showers arrive, so some local brief freezing rain is possible.
Then, some scattered showers should follow for the day off & on with mostly cloudy to cloudy skies.
After highs briefly 44-50, we should fall into the 30s to 40 in the afternoon. Northwest winds may gust to 35 mph by evening.
Lows of near 18 are likely Wednesday night with wind chills near 0.
Watch the brutally cold air try its best to plunge southeastward right into our area & then watch the Southeast ridge prop it up & begin to shove it back north & northwest!
It is skyrocketing southeastward & then hits a wall.
Granted, it will get sharply colder briefly, it will not get as cold as it could.
The ridge should guide the next storm system into our area, but with a track that would tend to bring not just all snow or all snow & ice.
Snow with change-over to sleet, then freezing rain, then rain, ending as brief snow is possible Friday afternoon to Saturday midday.
Howling winds should follow Saturday afternoon with tanking temperatures & northwest winds gusting +40 mph at times.
Even with the system's precipitation, winds may gust from the southeast, then south up to 30 mph at times.
Snow & ice accumulation is likely with this storm system.
Change-over to rain is forecast to occur near & after midnight Friday night as temperatures rise from the 20s to 32 to near 38.
Potential is there for 0.75-1.25" of liquid here, part of that being rain atop frozen, ice & snow crusted ground.
1.5-3" may fall south of I-70, leading to additional flooding woes.
Arctic high is forecast to be right over our area beyond next weekend to around January 21 with very cold air. Some lows below zero are projected.
WIth lack of snow pack, we are looking at -5 to 3 at the moment.
Snow pack in northwestern Illinois & Iowa may allow -25 to -20 lows.
This NOAA projection shows the brutal cold leaving Alaska, but more of it blasting into the Lower 48 in late January.
Overall temperatures look below normal & snowfall above normal late January through early February.
