Today was down--based on evening radar, appears to be a good call despite the Moderate Risk from SPC so far (Whew!). Westerly H5 winds with easterly surface winds aren't the best for tornado producing supercells.
TWISTEX group is targeting the next powerful system to emerge into the plains ...

A great day for TWISTEX yesterday. Deployed three in-situ probes (two HITPR, and one Photogrammetric probe), and the MMs were spaced roughly 1 km apart with M3 near the circulation, and M1 deployed south. Probes took a direct hit. Basically, a north-south deployment of in-situ core measurements ...

Looks like a busy day is in store for us as excellent shear and moisture sets the stage for supercells, large hail and tornadoes in central/eastern Nebraska. Warm front will lift northward today through central Nebraska towards the O'Neill area by 0z. Storms should initiate in ...

Moisture is working its way back into NE at the moment, with a projected surface low somewhere in southwest Nebaska/northeast Colorado. NAM models suggest some zonal flow over this area with some southwest flow further west.
At the moment, we're targeting an area of the warm front from ...

Bruce, Cathy, Verne went back to Quinter to survey the damage yesterday morning. Verne flew the TWISTEX plane to collect still/video imagery of the damage path. Group surveyed about 8 miles along the path until early afternoon until it was time to chase.

Yesterday, we intercepted two tornadoes near LaCross, but the tornadoes were rather brief (one tornado, one landspout) that we didn't have a chance to deploy. Tried to collect hail in three different storm cores, but only marble to golfball size hail was observed.
Today, we have a ...

Yesterday, storms tried to initiate along the dryline near Grand Island, but quickly fell apart. Storms did initiate further north in northeast Nebraska, but the appearance on radar showed them to be struggling in the low Cape environment.
Today, a surface low begins to deepen in southeast Colorado ...

Another great day. Intercepted 6 tornadoes.
Witnessed large wedge tornado north of Quinter-an amazing transformation of a 'stovepipe' type tornado to the (what appeared to be) entire mesocyclone rotation dropping immediately to the ground-creating the wedge. Similar view caught by another chaser is currently on TWC. All three ...

Great day. Collectively intercepted an (estimated) 7 tornadoes, several at very close range. Collected data on 3 of the tornadoes.
Today is a repeat of yesterday. Surface low redevelops in CO with mid level winds even slightly stronger than yesterday. Incredible upslope flow with good moisture entrainment by ...
