Thursday 16th June 2016 – N Dakota – Slight Risk

Today’s risk would take us back east to North Dakota. A slight Risk of Supercells with a small risk of a Tornado but only if the cap could once again break. My target was Bismarck which was on the triple point and we went there for an early lunch and watched the boundary bubbling away.

At about 730pm finally the cap broke but it was slow going and the cap beat down the first couple of storms but the storm below would go on to become 1 of a pair of Supercells that would sit stationery South West of Bismarck for most of the evening. We stayed east of the Missouri River thinking they would move North East but had to watch from the other side for the rest of the evening.

We did find an amazing viewpoint South East of Bismarck and watched for a few hours lightning dancing over the Missouri which in itself was amazing, Tim Marshall and the TWIRL crew also joined us in this tranquil setting.

After that we went back to the Hotel and were awoken at 430am to an intense Bow Echo rattling across North Dakota which brought 70mph winds and Golfball sized hail. A very early wake up call!

Saturday 18th June 2016 – Montana – Enhanced Risk

Started the day once again in Glendive and most of Northern and North Eastern Montana was under an Enhanced risk for today mainly for hail but a decent 5% Tornado Risk as well. Storms would be very fast moving and some models had the storms crossing into Canada today as well which would be fun to chase if it were to happen. Got to Malta at 3pm and waited on Initiation and as the day went on both the HRRR & Nam4Km agreed on just a few Supercells heading North East from the Great Falls area and following Highway 2. We positioned south to get a good look at the first Supercell of the day which promptly went tornado warned when it was 25 miles to our west, a big problem with this storm was both its motion and speed. Firstly it was moving at 60-70mph and secondly moving through an area of lakes with no roads for 70 miles. This was going to be fun!

After letting the rotation go right over us we were slammed with 70mph RFD winds which took Craigs door completely off his vehicle. This delayed us somewhat as we tried to fix his door and untilmately stopped us from getting back in front of the storm which was now racing away at 80mph (An Impossible Task) After getting to Glasgow we dropped south to another Supercell and watched as Lightning flickered away as the day ended.

After that we went back to Glendive (AGAIN!) and shot some lightning over the town
