June 20 (Day 0)
It is about 8pm and my chase partner for the next 10 days or so, Vince Miller, will be arriving here in Dodge City in about an hour. We’ve been discussing on the phone our tentative game plan for the next couple of days. Tomorrow, June 21st, looks like a pretty good severe weather day across South Dakota and Northeast Nebraska. It is unclear our exact target yet, but anywhere from Central SD to far NW Iowa looks interesting… my gut says farther west into SD, though, with moist easterly surface winds over much of the state ahead of a small jet streak/shortwave trough. Then, Friday, we plan on blowing off Iowa and heading northwest towards North Dakota… more or less a travel day to get into position for Saturday which looks like a potentially good day in far southern Saskatchewan in Canada. There could be isolated picturesque storms in western ND on Friday 22nd. Sunday the 24th could also be in North Dakota as the upper trough will be slow-moving. Going into early next week…still a lot of uncertainty and we will cross that bridge when we get there! We are driving from Dodge City to Kearney, Nebraska this evening when Vince gets here…staging for tomorrow’s chase.
This could be a high plains surprise event. Notice the moist outflow across the northern
NE panhandle. Storms could develop around Scottsbluff and and move into the higher
dewpoints east/north of the outflow boundary?? Perhaps Alliance, NE today?? 60s
dewpoints at 4000ft could be trouble??
