High latitude blocking will continue to mature over the upcoming 6-10 day period. This will force a very stormy pattern underneath (across the Lower 48). After the light snow late tonight and Saturday morning (primarily grassy and elevated surfaces), we’re tracking 3 additional storms over this particular time period and each of these will deal out their own respective challenges that we’ll have to hone in on as the system(s) draws closer. Our daily posts and Client videos will handle those specifics.
Storm dates:
While we’re not looking at anything particularly noteworthy (in terms of relative to average) in the cold department over the next week, this begins to change by the 8-10 day period. Admittedly it’s been challenging trying to time when the arctic air sloshes east in this type pattern, but it’s becoming increasingly apparent that this should take place around mid-month. Note the cross polar flow developing towards the 10-15 day period, per this afternoon’s European ensemble update.
Just how cold are we talking? Subzero lows and highs around 10°F without a snowpack. Should we have a snowpack down by this time then the threat of a double-digit below zero low and highs in the single digits is on the table. The target date for this cold comes between the 14th and 18th. Wind chills will obviously be much colder.
The plot continues to thicken…
Updated 01.04.24 @ 6:46a Enjoy the last couple of quiet days while you have them. Skies will slowly brighten later today, but otherwise anticipate mostly cloudy and seasonably cold conditions.…

Today’s 12z guidance continues to reflect quite an active and stormy period of weather kicking off this weekend, continuing through mid-January. This is a byproduct of all of the high latitude blocking that develops over the span of the next 6-10 days.
The negative PNA is putting a real wrench in any one of these “meaningful” area of low pressure systems, Saturday’s excluded, from being totally on the wintry side. Look for above normal precipitation over the upcoming 6-10 days with plenty of mixing events going on.
Speaking of that, we don’t have any changes to our thoughts on the first two systems:
Saturday- light snow should overspread the region through the morning hours with light accumulation, primarily on grassy and elevated surfaces. We’ll firm up snow numbers over the next 24 hours. Note, additional light snow, potentially mixed with light rain, should fall Saturday night into Sunday as upper level energy scoots across the state.
Monday night/ Tuesday- after a calm open to the work week, clouds will increase Monday PM and give way to a wintry mix of rain, sleet, and snow across the state Monday night into Tuesday morning. As warm air advection kicks into high gear, the wintry mix will transition to a cold rain for central and southern IN. Further north, it’s a tougher call with mixing issues hanging on longer. Heavy precipitation and strong/ gusty winds can be expected Tuesday. We all turn colder Tuesday night with rain transitioning back to wind-whipped snow/ snow showers that will continue Wednesday with additional light accumulation expected.
Wednesday night/ Friday- another potential significant area of low pressure will impact the region during this particular time period with additional heavy precipitation (likely another mixed bag event) and strong winds.
The initial dump of bitterly cold, arctic, air will target the West through the 6-10 day period before making an attempt to bleed east (likely in modified fashion) during this period. Per our longer range discussions, the MJO will have the primary say in our late January pattern and we’ll have fresh long range thoughts posted prior to week’s end.
Make it a great evening!
