Cagliari is located on the southern coast of Sardinia, an island and Italian province off the western coast of Italy. Cagliari is the capital of Sardinia and is home to nearly 160,000 people (about 400,000 in the metro). This city was established some time in or before the 7th century B.C., between the sea, fertile plains, and mountains. Today, Cagliari has one of the largest fish markets in Italy and tourism is a major part of economy.
A few more facts about Cagliari (from Wikipedia):
- Time zone: Central European Time (UTC+1) or Central European Summer Time (UTC+2)
- Elevation: 13 feet
- Climate zone: Mediterranean
- Average high temperature: 70 °F (21 °C)
- Average low temperature: 53 °F (12 °C)
- Average annual precipitation: 17 inches (426 mm)

Current weather: This week in Cagliari, highs are in the mid-60s and lows are in the low 50s. Skies are expected to be mostly clear, after a chance of rain Wednesday night and Thursday night.
With a trough and an associated surface low moving over France today,y there is a decent chance for severe weather (strong wind gusts, tornadoes, and excessive convective rainfall) in Sardinia and across much of the Mediterranean. ESTOFEX, the European Storm Forecast Experiment, has made the following forecast:

Next Tuesday I plan to take a look at the climate and weather in another part of the globe. As always, if you have any comments or suggestions for future cities, please leave a comment!

The National Weather Festival, an annual event at the National Weather Center in Norman, Oklahoma, will take place tomorrow from 9 am to 1 pm.
I’ll be there with my chase car (entered in the storm chaser car show), and I’ll also have a booth inside with DVDs, prints, calendars, and T-shirts for sale. I’ll also have some free pens and storm chasing brochures.
I’ve been spending a lot of time preparing for this lately, hence the lack of blog posts this week.
Between the demonstrations (e.g., balloon launches), tours of the building and research vehicles, storm chaser car show, prizes, booths with weather info and vendors, etc., the National Weather Festival is always a lot of fun. Last year I believe there were around 5,000 people who showed up!
Here’s a link with more info: www.nationalweatherfestival.org
As an aside, there will also be fireworks tomorrow night in Norman, as part of a Vietnam Veterans’ celebration. These will be the fireworks saved from the 4th of July, after that fireworks show was rained out.

Series note: from here on out, I will skip Antarctica in the World Wide Weather continental rotation. Occasionally we may return there, but for now, we’ll rotate through just the other 6 continents.
This week’s post in the global weather and climate series features International Falls, Minnesota.
There is currently a very strong extratropical cyclone centered just north of International Falls, so we’ll be taking a brief look at that today.

Rainy Lake, on the Canadian border near International Falls, Minnesota. From MinnesotaLakes.net. Click to enlarge.
International Falls is located in northern Minnesota, just across the Rainy River from Lake Frances, Ontario, Canada. The city is officially known as the “Icebox of the Nation”, following a 2008 trademark lawsuit with Fraser, Colorado. International Falls receives bitterly cold and snowy winters, but humid and hot summers. Settlers first arrived in the area in the 1600s, but the city did not become incorporated until 1909. The population (census 2000) of International Falls is 6,703.
A few more facts about International Falls (from Wikipedia):
- Time zone: Central Standard Time (UTC-6) or Central Daylight Time (UTC-5)
- Elevation: 1,122 feet
- Climate zone: Humid continental
- Average high temperature: 49 °F (9 °C)
- Average low temperature: 26 °F (-3 °C)
- Record high temperature: 103 °F (39 °C)
- Record low temperature: -55 °F (-48 °C)
- Average annual precipitation: 24 inches (608 mm)
- Average annual snowfall: 68 inches (173 cm)
Current weather: Focusing on the record-breaking low-pressure system affecting International Falls, here’s the latest surface map from The Weather Channel, as of 5:43 pm CDT (click to enlarge):
As you can see, there is a large low-pressure system centered just north of the Canadian border, with a very tight pressure gradient (the lines on the map are isobars, lines of equal pressure).
Now here’s another surface map, showing actual observations, from the Oklahoma Weather Lab from 3 hours ago, at 3 pm CDT (the more recent one has a slightly lower pressure, but the contours ended at the border):
Note how the contours are so close together. Note also the low pressure–on this map, the pressure at International Falls was 959 mb! Actually, this extratropical cyclone set new minimum, non-tropical pressure records in Minnesota and Wisconsin as well as the US as a whole. So aside from landfalling hurricanes, this system brought the lowest pressure ever recorded over the US mainland: 956 mb! This is the equivalent pressure of about a Category 3 hurricane!
The pressure is so low, and the pressure gradient is so tight, the winds around the low are very strong. There have been some gusts to well over 60 mph in the Upper Midwest.
Today has also been an active severe weather day, as storms have formed all along a cold front as well as out ahead of the cold front, producing high winds and tornadoes.
As I mentioned yesterday, if the air behind this system was just a little colder, there would be the potential for a major blizzard over the Northern Plains. As it is, there is some snow falling (see the Weather Channel map, above), but not enough for a big blizzard.
For weather maps and information on current and forecast International Falls weather, see the National Weather Service and Weather Underground.
For more information on International Falls, here’s a link to Wikipedia and here’s a link to the city’s webpage.
Next Tuesday I plan to take a look at the climate and weather in another part of the globe. As always, if you have any comments or suggestions for future cities, please leave a comment!
