Does Pennsylvania need to prepare for a drought?

Meteorologist Dan Tomaso from ABC 27 WHTM joined The Spark to update us on the upcoming weather. We are in another heatwave, and that could possibly impact Centra PA residents with a drought.

“So let me go to a formal definition here. So, there’s something called a rapid onset drought. And that’s probably what most people are familiar with. And what you can typically see with that is your lawn, maybe your garden really beginning to dry out. So, it’s really, sensitive vegetation that you can see, really take a hit in that type of environment. So, a flash drought or a rapid onset drought is when we see an intense intensification of any type of dry condition due to changes in precipitation, temperature, wind and then increasing sun. So, we’ve had that over the last month that we’ve had a lot of sunny days with very few areas of cloud or showers. And what that does is it really limits how much moisture is getting back into the air. So, we have a lot of rain, the plants, the trees, they also give off rain through a process called evapotranspiration. So, it’s basically the plants, the trees breathing moisture into the air. Also, when there’s a lot of rain the soil moisture is very, very high. So, in the morning we can see two or we can see fog. Sometimes at this time of the year when there’s a drought setting in, you don’t see a whole lot of it. You don’t see a lot of morning Dew; you don’t see a lot of fog. So, when we start losing moisture from the trees due to heat stress from our plants, also from the moisture from the soil moisture, that’s when drought really sets. And that’s when you kind of see the dry, crunchy grass. You see the really dry soils, the loose soils. And on a windy day too, you can see that soil being kind of lifted into the air. Now, again, this is not talking about the severe drought of the desert southwest right, the West Coast, United States, we see a lot of videos from. But they do have impact here in Pennsylvania.”
