Hello,
the last two days offered again very exciting and diverse weather. Rarely can you name within less than 48 hours 31 ° C and dusty roads and 13 ° C in the downpour, bright sun with gusty south wind and severe storms, including severe dust storm to do so close to each other, as was the case with us.
On Memorial Day (Monday) on which they do in the U.S. those killed in the last war and the veterans began the day for us in McCook, Nebraska. A Slight Risk issued by the Storm Prediction Center and we presented a strong storm, possibly one or two super-cells. The wind shear was somewhat weak in the chest, so it should probably be more storms, especially the cool, strong downdrafts were determined and less of rotating thermals, tornadoes and the like.
Well we went yesterday for a sociable chat with the tenants of one of Days Inn Motel in McCook (for delicious sandwiches were also the same time exchanged contact details) about noon on a lonely highway north through the hilly, fairly barren landscape. With strong southerly wind blew over again flat clouds approaching from the south, there were also first with a few cirrus clouds little to see. Julian and I took the time to get to brown a bit and to look out for any animals. Soon, however, was located southwest of our observation site, a small cluster of somewhat stronger Cells.
These cells, more specifically, a thick version, moved very slowly and it had formed on the flanks of this storm ever new storm. Finally gave the National Weather Service out for the whole region, a flash flood warning, since it was from heavy rain and flooding. We tried the meantime, come north to North Platte and drove even after the Interstate 80 West. As it turns out that from the west meet is not as much, and should the storm here in the near time and again formed, we decided for a ride back toward McCook. This option led us in the middle of pure Flash-flood history, After a while the waters came down from heaven so close that we could not see 20 meters wide. Left and right gathered in the meadows and fields of water, the sky was dark gray to brown and always flickered somewhere above us flashes. Even some hail was present us we needed a good 30 minutes to get out of the cloudburst once again come out.
developed the evening, on the southern and southwestern edge (for the Mets: thanks LLJ) strong new cells and a tornado was even bewarnt. We have seen up close. Effective display worked its way out for about 15-20 minutes a circulation, but the air was in the vicinity of the storm from the previous rain rather cool and stable, there is nothing out of the tornado warning has become. It was great to watch, however, as the cell is very short time increased and the flash rate was higher. Again and again hammered into the ground and blinding flashes.
On Tuesday we made our good time in a new "target area", this time it looked like the morning after data from storms in southwestern Kansas and southeastern Colorado. So we went to a small breakfast (which was attended by a Stormchaser Tour of Roger Hill, with over 20 people) to the south in the direction of Garden City, Kansas. Once there we found at least a strong southerly wind and shallow cumulus clouds, the air was very dry (dew point: 14 ° C) to the west and there was not even more, but even fewer clouds. Something was wrong and that new data check confirmed our feeling that has Slight Risk is sometimes just shifts it some 200 miles northwest. After supercell saw it first in our region now from no more and so we drove back north, angry, but the weather can not always look to the cards. Colorado, meanwhile, already went through it around with several severe storms and tornado warnings a few. All of these storms should continue in the following hours walk to the east and southeast Kansas gene.
On the way to the northwest via Interstate 70, the radio beeped again and Weather There were several warnings of gale force winds and hail from a huge line. The same edge we reached the small town west of Colby, and it was all over western and north-west jet black. This roller was moving at 50 km / h to the east and the wind blew in the gust front so severe that vast amounts of dust and earth torn up and shipped across the landscape were. This whole storm front slowly changed to the dust storm and the sky was eerie brown.
thundered After an initial vulnerable phase, then a few gusts over our site and other materials were pulled up in dust, soil and small stones. On video you can see the dynamics of the whole good, wait for the cutting of the clips but it still needs.
News
blows it out there are still violent, but most of it is due. Even if it was not enough for a tornado (there were five reports today, but only very short-lived events in Colorado), so it was a pretty impressive Chasing.
Ciao, Lars
+ Julian
