Rain chances are back – modest, but back

Moore County has been so dry lately that it feels like the last real rain fell back when Moby Dick was still a minnow.

That may be a stretch.

Then again, maybe not by much.

If you’ve been staring at the sky, eyeing your brittle yard, and wondering whether the clouds have started skipping Moore County on purpose, Southern Tennessee Weather’s Elijah Kirby has an answer: Yes, some rain is on the way – just not enough to make anybody relax.

Thursday gives us the first real shot at rain.

Kirby says a weak boundary will slide into the region tonight into Thursday, bringing showers and maybe a few thunderstorms. Northwest parts of Middle Tennessee could even catch a small cluster of storms Thursday evening.

That sounds encouraging until you get to the question everybody really cares about: How much?

Probably not much.

Most places, Kirby says, will see around a quarter-inch of rain or less. A lucky few might pick up a half-inch. That helps. It just doesn’t move the needle much.

In weather terms, it counts. In yard, garden, pasture, and creek terms, it barely counts as a favor.

Saturday brings another chance, this time with a stronger cold front moving through Saturday into Saturday night. On paper, that sounds like the kind of setup that ought to bring a widespread soaking rain, a little thunder, and at least one person saying, “Now that’s what we needed.”

This one still looks a little tightfisted.

Kirby says the air ahead of the front remains fairly dry, and much of the storm activity is likely to develop along or even behind the front. That kind of setup usually keeps both severe weather and rainfall totals in check. So yes, rain chances go up Saturday. Yes, most of us should see rain. No, it still does not look like the kind of rain that ends a dry spell and sends people dancing into the driveway.

Half an inch, give or take, is helpful.

It is not exactly coming to the rescue.

So, What Exactly is Rain?

If you remember, at its most basic, rain is what happens when water evaporates, rises into the atmosphere, cools, and condenses into tiny droplets inside clouds. Those droplets bump together, grow larger, get too heavy for the air to hold up, and fall.

That’s the scientific version.

The Moore County version is simpler: Rain is the thing people start bragging about the minute it lands in the gauge, even when it was only enough to tamp down the dust and make the porch smell good for half an hour.

In other words, rain is gravity finally winning an argument with a cloud.

And What is a Thunderstorm?

A thunderstorm is a rain shower with ambition.

Officially, it’s a storm with thunder and lightning produced by a tall, fast-growing cloud. That’s the part that matters. If you hear thunder, you are dealing with a thunderstorm. Not just a dark cloud. Not just a passing shower. Not just weather that made the dog nervous. ... Thunderstorm.

These storms form when warm air near the ground rises quickly into cooler air above. As that air rises, the cloud grows taller, droplets and bits of ice start colliding, electrical charges separate, and eventually lightning flashes.

Thunder is the sound that follows when lightning heats the air so fast that it expands like a sudden little blast.

So no, thunder is not “just thunder.” Thunder is lightning making an entrance. And lightning, as usual, is the sky showing off.

Is the Pattern Finally Changing?

That is the bigger question – not whether we squeeze out a quarter-inch Thursday or maybe a little more on Saturday, but whether the pattern itself is finally starting to loosen up.

Kirby says the answer is ... sort of.

The ridge that has been parked over the Southeast is beginning to weaken just enough to let more systems slip through. That is why rain chances are starting to show up more often. But it has not fully broken down, so this is not a dramatic flip-the-switch change.

It looks more like spring is finally cracking the door open. That is the part to keep an eye on.

Long-range guidance heading into late April suggests the overall pattern may become more zonal, meaning systems can move across the country more freely rather than being blocked by stubborn high pressure. There are also signs of a wetter pattern across much of the central and eastern United States, and the Climate Prediction Center outlook gives this area a decent chance of above-average precipitation toward the end of the month.

That does not mean Moore County is about to get a biblical soaking. It does mean hope has at least wandered back in.

What Changes First?

The first thing people notice may not be the rain at all. It may be the cooler air behind it.

Behind Saturday’s front, highs on Sunday should drop back into the 60s, and mornings early next week could dip into the upper 30s and 40s. After this early taste of summer, that cooler air is likely to get people’s attention first — especially the ones who step outside before sunrise and realize spring has decided to act like spring again.

So yes, Moore County may finally hear some thunder, watch a few showers pass through, and maybe pick up enough rain to freshen things up for a minute.

For now, though, this still looks more like a tease than the real thing. Keep the umbrella handy and your expectations in check. The rain may not be ready to move back in, but at least it finally remembered our address.
