Possibly you’ve got lived in North Texas for a while however by no means understood what the cap is. Or maybe you’re new to North Texas, and stay utterly confused by this time period.

The cap is a heat layer of air within the ambiance above our heads. Often, this layer of air is round 2,000 to five,000 ft up within the ambiance.

The rationale we name it a “cap” is as a result of this layer of heat air acts like a lid, stopping storms from with the ability to type. Consider it like a pot of boiling water with a lid on high. When the lid is on, hardly any steam could make it out of the pot. However while you take away the lid, all that built-up steam rises very shortly out of the pot. So when a cap is in place, thunderstorms have a tough time forming — as a result of that cap or lid is protecting any air from rising and, thus, any thunderstorms from forming. 

Once more, needless to say the cap is sort of a lid on a pot of boiling water.

If the cap is not there, storms can freely type, though it’s onerous for them to change into extreme. Days that do not characteristic a cap are normally days that characteristic widespread on-and-off showers and storms, however not a lot in the way in which of extreme storms. Are extreme storms attainable in these circumstances? Positive! However they don’t seem to be as widespread.

Consider how when a lid isn’t on the pot, and steam simply retains rising again and again, however stays fairly fixed in its depth. Now, take into consideration while you’ve had the lid on the pot and you then shortly take away it. All that steam abruptly bursts forth quickly out of the pot.

That is similar to what occurs when the cap breaks right here in North Texas.

In these cases, when heat, unstable air beneath the cap breaks by way of the cap, thunderstorms type very quickly within the ambiance and might shortly change into extreme. Vitality has been brewing beneath the cap for a while, so when it breaks, thunderstorms can change into fairly robust — and really shortly at that.

These circumstances are after we normally see the robust storms we are able to get right here in North Texas — storms with very giant hail, damaging winds.

One of the best probability for thunderstorms as we speak will probably be within the 3 p.m.-10 p.m. window. Have a look.

General, the warmer-than-normal temps look like right here to remain for some time.  Storms are attainable Monday, Thursday, and once more Memorial Day weekend.
