Don’t get used to any one particular pattern for any length of time over the next few weeks. “Active” will sum things up best in a single word as a transitional regime takes hold.
The NEW JMA Weeklies highlight this transitional theme best over the upcoming (4) week period.
Week 1
Week 2
Weeks 3/4
To no surprise, especially given the transitional nature of the pattern, the upcoming few weeks should feature above normal rainfall for a good chunk of the Great Lakes and Ohio Valley.
We’ll also want to keep tabs on the potential of greater than average severe weather episodes, notable considering we’re almost into April. It’s a byproduct of the “topsy-turvy” look to the overall pattern.
Pattern drivers, including the EPO, back up the transitional them over the upcoming couple weeks. Reminder, negative phase favors chilly conditions and positive phases favor milder air (compared to average). This look, too, screams wet and stormy.
Bottom line, buckle up for an active storm track and associated heavier than normal rainfall over the next few weeks. Temperature regimes will feature a bit of it all, including above and below normal periods, likely all balancing out slightly above normal when all is added up.

High pressure will build overhead and allow increasing sunshine through midweek. Enjoy that Vitamin D while you can, as a wet pattern emerges for the Easter weekend and into early next week. Multiple rounds of heavy rain may eventually lead to a flood risk by early next week.

“Busy” is one way to describe the upcoming week to 10 days worth of weather as the pattern around these parts, and a large chunk of the East, takes on a spring look and feel. Everything from thunderstorms, rain, clipper snow, and an opportunity for strong to severe storms is included in the week ahead.
An area of low pressure will move through central and southern Indiana this afternoon, continuing to present scattered to numerous showers and thunderstorms across the area. While north-central Indiana has been the focal zone for early morning activity, we anticipate more of central and southern Indiana will be impacted throughout the afternoon and early evening.
All of this precipitation and embedded thunder will push off to the south of the area around or just after dinnertime. A quiet night is on deck with cooler air flowing back into the state. This will lead to a calm close to the work week as temperatures “warm” back to around 50° Friday afternoon as sunshine returns.
As we open the weekend, a rapidly moving clipper system will drop southeast across the region, eventually leading to several inches of wet snow for the east TN and western NC mountains. Back here on the home front, a period of snow is expected to develop late Friday night and predawn Saturday. While this certainly won’t be anything like what we saw last Friday, a wet coating of snow is possible in spots as this upper air feature dives across the region. By daybreak Saturday, all of the snow will be out of the area and we’ll be talking about working in more in the way of sunshine into the mix as our day progresses. Gusty northerly winds Saturday morning will diminish as the day wears on.
A quick warm-up is on the way for the 2nd half of the weekend. In fact, highs will approach 60° Sunday afternoon (how’s that for weather whip-lash?!). These warmer times will allow a more potent round of storm to rumble across the region as we progress through the early stages of next week. A warm front will lift northeast across the region Monday with showers and then attention turns to the threat of strong to severe thunderstorm potential as we go through our Tuesday and Wednesday. More on the specific timing and severe threats (damaging straight line wind appears to be the biggest concern from this distance) with updates to come in the days ahead.
The Storm Prediction Center (SPC) is already highlighting the region for the opportunity of severe weather Tuesday and Wednesday.

Week 1 remains significantly wetter than normal across not only our neck of the woods but a good chunk of the East.
This will give way to a quieter Week 2 timeframe.
There’s some threat that the southern tier and immediate eastern seaboard never is fully able to relish in the magnitude of the warm anomalies the majority of the rest of us will see as we roll through early February. Just to reiterate, as much as we believe cold, wintry weather returns in February, it’s not after a significant period of milder times (compared to average) to open the month- likely the first 10-14 days.
Just how mild are we talking? Several days with highs into the 40s and even 50s and overnight lows in the low to mid 30s. This compares to early Feb “norms” in the low 20s and highs into the upper 30s. It’s a byproduct of the MJO and alignment with the teleconnections (PNA aside) in the warm phases. As shown Monday in our LR video, we believe this all flips around in a big way later into the month, continuing into March.
In the short term, additional waves of rain (and dense fog) will keep things gloomy around these parts. Most widespread rain will come at us now through late morning before returning Thursday evening-overnight. Most rain gauges can expect to pick up an additional 0.75” to as much as 1.25”+ during this time period.
Modeling continues to differ in a major fashion with the weekend storm. The GFS is further north with heavy precipitation and a transition to leftover snow showers, locally while the European takes the suppressed route. Today will likely bring alignment between the two solutions. . .
Updated 01.20.24 @ 11:50a Arctic high pressure will build overhead this weekend and while we still have a couple days of very cold weather to contend with it won’t be…
