![]() So extremely violent and in such an amazingly short period of time. It's just that the storm forms so so close to the safety of all the cold outflow already generated and that it also becomes ![]() It is really scary to realize this evolution is possible. Two of them in particular grow and rotate extremely rapidly. But a couple storms pop up immediately ahead of the complex, taping into very unstable air still available there and also the better surface winds that are It had pretty quickly grown into a cold outflow mess, with an extremely So the early stuff in Kansas continues for a couple hours, doing little more than some mild hail reports. Just the orientation of the stuff popping off in Arkansas suggests to me effects of that outflow boundary are arcing up near Joplin, likely south a bit. On this wide view of the radar you can see the boundary in Arkansas popping off storms as well as theĭry line in the plains and the gravity wave across central Missouri Then in nearly the same area you get a storm that pops up just ahead of it(but later on and more east in better low level orientation and flow) and that storm The old storm in southeast Kansas had been going for hours and did really The storm popping up later and to the east in the better environment, made a massive difference. It's much more clear on radar but figured I should point it out on here. Note that what moves over Joplin isn't a continuation of the convection in southeast Kansas but new storms marked by those new overshooting tops that pop up right before moving What is for sure is that just ahead of the dry line early, the winds were veered southwest, but that to the east, if they weren't already south, they soon would be. I'd say there are some effects of that boundary back Just west of them it appears that "line" curves and points northwest towards the northeast corner of Oklahoma. ![]() If you watch real close where the Arkansas storms are firing, you can see them doing so on the same sort of line. Here is a closer in look with Joplin marked with the box. However, it is not all bright and sunny, as the city is partially clouded for most of the year, with cloud coverage oscillating between 25% and 45%.Your browser does not support the video tag. The months of April to October have more daylight hours, between 13.2 hours to 14.7 hours, coupled with longer sunshine duration from 8.3 hours to 10.7 hours a day. Joplin's unique weather phenomenon is the absence of a dry season leading to a climate that is persistently humid. The number of rainfall days ranges between 6.8 and 16.8 days per month, while snowfall is rare, with measurable amounts falling only from December to March. Precipitation is distributed fairly evenly over twelve months, with rainfall averaging from 1.54" to 5.04", indicating a consistently moist environment. This temperature variation is coupled with a relative humidity level that averages between 71% and 79% throughout the year. Monthly minimum temperatures show a similar trend, moving from 27.3☏ on the cooler extreme to 69.8☏. A noticeable annual variation in temperatures is observed, with monthly highs ranging from 42.3☏ in the colder season to 89.2☏ in the summer months. Located in the Midwestern state of Missouri, Joplin experiences a Humid Subtropical climate with no dry season, based on the Köppen Climate Classification.
