The upper-level ridge of high pressure that I spoke about all of last week that I thought would bring hot conditions all week long to Greater Nebraska ended up being not quite as strong as I thought it would be. Here is a snapshot of what I though the weather map would look like in general this week:
What I envisioned was a strong ridge of high pressure in the mid-levels that would act to keep the jet stream farther north, which would not allow disturbances riding along the jet to send fronts far enough south to keep us cooler, and keeping any "Ring of Fire" thunderstorms circling the northern periphery of the high mostly to our north.
But here is what is really happening:
As you can see, the northern part of the high-pressure ridge has a "flatter" look to it because it is not as strong. This has allowed the jet-stream to be oriented a bit farther south. As a result, disturbances riding along the jet to our north have been able to send fronts farther to the south across our region, rather then being held to our north. This is allowing two things: temperatures that are cooler and more numerous showers and thunderstorms.
Unfortunately, it looks as though this same general pattern will be with us this week, so expect warm and humid conditions with lots of clouds, and the chance of thunderstorms at just about any time, though the risk will be greatest later in the day. In addition, any storm can be strong to severe and dump heavy rain. Highs will be anywhere from the middle 80’s to the lower 90’s, though southern areas like Imperial may be able to sneak into the middle to upper 90’s, especially later in the week. Lows will be mainly in the middle 60’s to around 70.
Regardless of the weather, enjoy the week!
