Weekend Weather Update for Sunday, February 4, 2018
Winter Weather Advisory Saturday late afternoon to Sunday evening.
Snow showers, possibly briefly mixed with rain, will move across the area this evening. Little to no snow accumulation is expected with these showers. Light snow will become more persistent overnight with accumulation starting. Brief moderate snowfall rates are likely during Sunday morning, especially over northeast Illinois into northwest Indiana. Snow will end during Sunday afternoon. There is some uncertainty in specific total snowfall amounts, as there is likely to be variability in the lakeside counties. Increasing northerly winds will drop temperatures quickly Sunday. These winds with the snow will also provide for patches of sharply reduced visibility, and some patchy shallow blowing snow in open areas.
As you are waking this morning you are looking out the window and saying “This ain’t nuthin” Just hold on cupcake. The combination of a dipping jet stream along with low pressure in the area has painted a “let’s dump it on the Chicago area” target over the entire Chicago area including the much winter weather milined Northwest Indiana. These conditions will persist throughout the week. As mother nature points the big snow nozzle at us, it’s difficult to predict the total accumulation. Right now we will say 2-5″. Lake Michigan undoubtedly with show it’s snow love for Porter and LaPorte counties as well northern Lake county Indiana which can and probably will add to the predicted accumulations in the form of lake effect snow during the week. Again this is just the beginning of a every 24-36 hour cycle throughout most of the week. Prep that extra wide snow blower you bought that will clear the driveway in a single pass.
With the extended forecast calling for a cycle of snow during weekend and into next week, we are pressing two advisory buttons now! The CLC (Checkout Line Congestion) and the HHHH (Hostess Ho Ho Hoarders) advisory. Remember there is a cause and effect here. The HHHHs move into the grocery stores causing CLCs. Remember the safety rules, no eye contact and keep all sweets and potato chips in a hard to reach place in your shopping basket. If they strike up a conversation while in line, just agree with everything by smiling and nodding your head occasionally . At all cost avoid politics! Be safe!
The Monday afternoon/evening commute could be significantly impacted by accumulating snow, as up to 1-3″ could already have fallen by commute time. Steady snowfall rates will continue during the commute and through much of the evening before tapering off. Preliminary forecast snowfall totals from Monday afternoon through late Monday evening are 2 to 5”, locally 5”+. Consider this an early heads up. Please plan accordingly.
The lack of snow over northern IL thus far this winter has been noteworthy, but that could be about to change. A parade of storm systems over the Pacific will ride the jet stream into the northern and eastern U.S. this weekend into next week. These systems will be fast on each other’s heels, with only about a 24 to 36 hour break in between systems. It is too soon to say how many of these systems will directly impact northern IL and northwest IN, but there does appear to be multiple opportunities for snow this weekend through next week.
The advertised active winter weather pattern appears likely to produce another round of accumulating snow Monday afternoon through Monday evening. It’s becoming increasingly likely that the Monday PM commute will be impacted by snow for at least portions of the local area. Fast on the heels of the Monday system, we’re tracking the potential for a larger storm system to bring accumulating snow to parts of Illinois and Indiana Tuesday afternoon through Tuesday night. There is plenty of uncertainty on the track of this storm system and how much, if any, of the local area will be affected, so it is too early to say how much snow, if any, will occur within the local area. Finally, additional rounds of snow are possible in the Wednesday night-Friday timeframe.
