Never Over ‘Till It’s Over…
The period outlined is March 6th through March 20th. As the block continues to mature, we think this timeframe will produce at least one (if not a couple) opportunities for “meaningful” accumulating wintry precipitation across the Ohio Valley and features below normal temperatures.
Model data continues to show this idea has merit and now we’ll have to handle the individual storms as they come. As we’d expect late in the winter, challenges abound, but this is a pattern that has potential. Can we turn potential into reality? That’s the question that will be answered over the next couple weeks.
During the upcoming week, snow showers will fly Wednesday, but this doesn’t appear to be a big deal. With vigorous upper level energy tracking across the region, it should be sufficient enough to generate scattered snow showers and potentially a couple more intense squalls (especially across eastern portions of the state) Wednesday.
The next item on the agenda will arrive Friday afternoon into Friday night. It, too, should spread snow across a portion of the Ohio Valley. With this being in the Day 6 time period, expect fine tuning as we move through the upcoming week.
Finally, a third system will impact the area about this time next week, and it’s this system that appears to be the most significant of the group. Far too early to get detailed, but it certainly warrants our attention.
The overall pattern we’ll “enjoy” over the next couple of weeks is one that’s been lacking for the better part of the past few winters. With blocking in place, storm systems trying to lift into the Great Lakes will be “forced” south and result in an active time of things around these parts- including the east coast, as well, over the better part of the upcoming 10-15 days.
Understanding that storms this time of year have to get several things to “line up” just right to result in an impactful event, it’s far too early to signal winter’s over…
II. We’re hopeful for much needed sunshine Sunday as we’ll be in between storm systems, however any sun that we see won’t last long.
While this is an unseasonably warm pattern (we forecast highs of 50°, or above, 5 out of 7 of the upcoming days, and at least 2 60°+ days), it’s one that will likely result in periods of heavy rain not only next week, but in waves over the upcoming 10 days.
Widespread 10-day rainfall numbers of 3″ to 4″ will be likely in this setup, including locally heavier amounts of 5″ to 6″ in spots. Certainly, if you live near waterways we suggest having a plan in place as it’s not a matter of if, but when flooding takes place in spots across the region with such a setup.
However, big changes begin to take place this weekend and will remain intact for the majority of the next couple weeks. The mean trough position will back into the west while ridging takes hold across the east. This will feature temperatures that will push to above average values and lead to an active and moist southwesterly flow.
Over the upcoming (10) days, temperatures may reach 50°, or greater, on 3 to 4 of those days. Compared to how frigid we’ve been (already had 7 mornings this month with sub-zero lows), this will feel like a heat wave.
Eight mornings so far this winter have plunged below zero. We’ll see if we can add another to that list this morning (IND is officially at 0° as we write this).
If you’re sick and tired of the cold, wintry conditions relief is on the way. We’ll turn “less cold” through late-week and above normal over the weekend (around 40° Saturday and into the upper 40s Sunday).
A storm system will cut into the ridge Sunday with showers (image 1) followed by “backlash” snow showers and gusty winds Monday (image 2).
Thereafter, models see another storm that will approach the region late next week. Since cold air won’t be readily available, it’ll take the perfect track to get impactful wintry conditions from this next event. We’ll monitor things closely next week. With this near Day 10, models will continue to struggle with timing, track, and intensity over the next few days.
As a whole, the second half of January should run milder than average. However, as we all know, that doesn’t mean we won’t have wintry challenges to deal with. The upcoming (10) days illustrates that nicely. Looking ahead, we note the MJO is forecast to rumble through the warmer phases (especially if you’re reading this from the eastern regions of the country- where we expect warmth to be most anomalous into early February).
Other teleconnections also support a relaxation of the cold, and warmer times, overall, with the exception of the Arctic Oscillation which remains negative through the period.
It should be noted that the longer range data and overall trends, supported by our analogs, suggest winter roars back with authority as we get into February. In fact, winter might not be so quick to leave this year either. Data paints a cold, wintry open to meteorological spring this year, but we’re getting way ahead of ourselves. It is only mid-January, after all. 🙂
