Downplaying

Never sell the SPC short, I will stay that. In our forecast for Sioux Falls, there were only a couple of mentions of severe weather in the forecast last weekend, from ourselves and Accuweather. Meanwhile, Sioux Falls was included in the severe outlook both Saturday and Sunday, and it verified, or did awfully close to town. Saturday had hail, 2 inches in diameter just outside of town. No rain was actually reported in Sioux Falls, however, reflecting the isolated nature of the storms. Sunday was a soaker, with hail (though not as large) and strong winds around town. The low temperature forecasts were volatile, and the rain on Sunday ensured a colder day than expected, so the forecast didn’t turn out great for anyone. Weathernation sneaked in by accurately avoiding rain on Saturday and having a cool low on Sunday.
Actuals: Saturday – 92, Low 67
Sunday – .61 inches of rain, High 80, Low 61

Above average Atlantic, Below Average Pacific

Welcome to hurricane season, everyone! For the first time in quite a while, the Atlantic has managed to avoid having a named storm crop up before the season started, though nevertheless, a busier than normal season is expected this year.

Even as this post is written, the remnants of Tropical Storm Agatha are being monitored for redevelopment in the southern Gulf of Mexico. It would be an interesting way to kick off the season, but the more traditional means of tropical development are, as now, pretty quiet across the Atlantic.

That portends to activity picking up later in the season. Even though this is the beginning of the tropical season, historically the most active period in the Atlantic comes at the end of summer, when the oceans are at there warmest. If the season waits to start and gets busier as it goes on, that will lead to a rough August and September.

Despite Agatha’s emergence in the eastern Pacific, the NHC projects a quieter than average season in the central Pacific. This is particularly important for both Hawai’i and surfers who come looking for big swells around the islands. There aren’t many other land masses that stand to be impacted by tropical features in the middle of the ocean, and even in busy years, Hawai’i isn’t impacted with much frequency.

Of course, with any season, what we remember is the storms that make landfall. Most residents of the Caribbean would agree that the Atlantic can be as busy as it wants to be, just so long as the storms stay out to sea and leave their islands alone. A quiet season in the central Pacific means nothing if one rogue cyclone nails Honolulu.

One last note. The beginning of hurricane season is also the dawning of meteorological summer. We made it, everyone. Happy summer!

Can’t beat the heat

Nothing is quite like the Texas sun beating down on you. Our forecasts didn’t quite anticipate how hot that sun could get when we forecast for Tyler, a town that looked like it was going to be in the aftermath of a cold front for a couple of days. Warming was anticipated, though not quite to the degree it was actually seen. Temperatures topped 90 on Friday, which is just a little too warm for sane people, and several degrees higher than what forecasts called for. The Weather Channel nabbed the top spot for the day, staying warm throughout their forecast period.
Actuals: Thursday, High 88, Low 58
Friday – High 91, Low 62
