Severe weather forecasting involves tracking storm systems using radar technology to predict rainfall intensity, flooding potential, and severe weather risks. Meteorologists analyze radar loops to monitor storm intensity changes, identify areas of heaviest rainfall (2-3 inches), and predict when severe weather conditions will recur. Flooding risks increase when heavy rainfall accumulates over time, and forecasters use historical patterns and current atmospheric conditions to warn communities about potential hazards.

Flood threat continues in North Texas as storms loom on Memorial DayAdded:
And welcome back as we head into tonight. We're still going to be dealing with some heavy rainfall and some flooding here across parts of North Texas. Still tracking a few isolated severe storms off to our southwest, but overall, if you want to know what a wall of water looks like, this is exactly what we had here across the metroplex. We had storms popping up right around 2:00 p.m. and they really intensified around 3:00 to 4:00. We had some severe storms here with flooding rainfall across parts of both Dallas and Tarrant counties. Currently, we have partly cloudy skies, a few areas, some pockets of mist and drizzle outside.
Temperature-wise, though, we are in the low 70s. And if you want to know where it's raining, take a look at this. I'm tracking a mix of rain-cooled 60s to our west. The rest of the region, we have temperatures in the low to mid-70s.
Current watches, current warnings, we still have some flood warnings in effect here off to the southwest, including one, currently just one severe thunderstorm warning as well. But on radar, most of the action continues here off to the south and to the southwest. We have an intensifying area of low pressure developing here south of I-20 and west of I-35 that will bring additional rain and storm chances here as we head into your Memorial Day.
But overall, you can see the subtle counterclockwise rotation here for this complex of storms. Lots of lightning with these storms as well here as we head into tonight. As far as any hail cores go, we had some hail at the beginning of this loop. This is a 1-hour radar loop. The good news is, over the last couple radar scans, you can see that the intensity and the size of the hail has really come down. So, the overall intensity and severe threat from these storms is going down as the minutes go by. But unfortunately, the flooding potential is continuing to increase here across North Texas. This is the rainfall that we saw here for today. Anytime you start to see the red on this map, that is 2 to 3 inches of total rainfall. And you can see widespread areas here, especially near Arlington, where we had the pockets of the heaviest rain this afternoon. We've had, as you saw right there, I'm going to go ahead and go back so you can take a closer look at that. We had some areas, look at this, between 2 and 1/2 to 3 and 1/2 inches. This is radar estimates of confirmed rainfall here for some of these areas. So, these are the radar estimates, I should say, not confirmed, but look at this. Heavy rainfall totals here estimated across parts of North Texas. Going forward in future track, you can see that over the next couple of hours, the storms I'm tracking off to the southwest, by midnight, 1:00 a.m., 2:00 a.m., they are continuing to to quickly de-intensify or continue to weaken here as we head into this evening and as we head into the overnight hours. But, there will still be some rain chances down here as the sun comes up. Before tonight, overnight lows will be in the upper 60s, which is on par with where we're supposed to be for this time of year. And as we head into tomorrow afternoon, still tracking some showers here off to our southwest primarily, but look at this. Right around early to mid-afternoon, same time frame as today, 1:00, 2:00, 3:00 p.m., there will be a chance of showers and storms here across the Metroplex, including that elevated severe threat, much like what we saw today. So, much like today, tomorrow will include a risk of severe weather during the afternoon hours, around the same time frame as what we saw here for today. So, keep that in mind. Heading into tomorrow, I'll be tracking a low to moderate to high chance of rain here for your Memorial Day. The highest chance of organized rainfall will still, once again, be off to the south and off to the southwest. Temperature-wise, look at this, we'll still be in the upper 80s to low 90s. So, it's still going to be a warm forecast here as we head into your Memorial Day afternoon. But, I also want to point out that as we go forward, temperatures are going to remain elevated and I am tracking pretty much a decent rain chance every single day here as we head into next weekend, which is also the first day of June. So, as we finish out the month of May, I'm tracking warm conditions, muggy conditions, stormy conditions, especially on Wednesday. That's when we're We're to see the highest chance of rain this week. But then after that, the rain chances will come down as the temperatures come up. We'll be at 89 on Friday. Look at that, Amelia. 90° on Saturday.
