A potential SVR weather episode is likely to unfold across parts of the Lower Mississippi River valley on Thursday, though the extent of a seemingly more appreciable TOR threat remains in question due to possible instability limitations. A mid-level shortwave, with an associated upper-level jet core of 120 kts, will move into the S Plains [...]

Convective Addiction storm chasers had an amazing year in 2010 with numerous supercell and tornado intercepts. Follow along as they document the adventure, excitement, and beauty of their chases through the Great Plains and Midwest from April to June. Watch dozens of tornadoes from small ropes with dramatic, grinding debris clouds, to massive, violent wedges. In addition, you’ll also see great supercell structure and other beautiful sights from the high plains of Colorado to the prairies of Illinois.

Right now a rather significant warm up is occurring across the country. Welcomed by many after a winter that saw mostly below normal temperatures. As expected a major shift in the pattern is underway, and the current warm up is the first sign of this. In fact, several of the most recent runs have shown [...]

As we continue to watch what appears to be at least a temporary (and optimistic) pattern change, the medium and long-range models are advertising some tantalizing respite from the arctic blasts and adverse winter weather which have been slamming the CONUS the past few months. For more on the teleconnections associated with this sudden respite [...]

A large part of the CONUS has been under the influence of rather extreme winter weather conditions since December. For example, the Groundhog Day blizzard set or tied 24-hour snowfall records in parts of OK, MO and IL. On a more recent note, heavier snow banding produced another bout of 12″ – 20″ + of [...]

Snowtorious B.I.G. continues to pound parts of the nation’s northeastern section, while leaving in its wake a crippling blizzard that will be followed by extremely cold temperatures and a continuation of blizzard to near blizzard conditions in the area encapsulated by its steep pressure gradient. Here’s a 6 AM surface analysis from the HPC: The [...]

As mentioned last night in our forecast post (CLICK HERE), the incredible lift and slantwise instability with this system are progged to produce some heavy mesoscale banding over parts of MO/IL. Please see last night’s discussion for more details about the parameters associated with these phenomena. Let’s take a look at some of the high [...]
