East Idaho just lived through one of the most extraordinary heat events in the region’s history — and forecasters say the record-breaking warmth isn’t over yet.

The National Weather Service said last week’s heat wave didn’t just break temperature records across the region. It obliterated them by margins so large that meteorologists said they’ve never seen anything like it in East Idaho.

City after city didn’t just edge past old records — they shattered them, in some cases by 10 degrees or more.

The numbers are staggering.

Idaho Falls may have seen the most dramatic stretch of the week. The city set five daily high temperature records from March 17 through March 21, with a 78-degree high on Friday that shattered the previous all-time March record of 73 by five degrees. Idaho Falls hit 73 degrees on Saturday, tying yet another daily record. Earlier in the week, the city hit 76 degrees on both March 18 and 19, surpassing previous records by 7 and 10 degrees respectively.

Pocatello wasn’t far behind. The Gate City recorded 77-degree highs Wednesday through Friday, shattering records on all three days. The previous Wednesday and Thursday records — set in 2017 and 1999, respectively — each fell by 6 degrees, while the Friday record was broken by 5 degrees. The 77-degree readings also broke Pocatello’s all-time March high of 75 degrees — a record that had only been set last year. On Saturday, Pocatello hit 72 degrees, tying the previous March 21 record.

The hottest temperature anywhere in East Idaho last week belonged to Burley, where Friday’s daytime high reached a scorching 80 degrees — breaking the city’s previous March 20 record of 73 degrees, a mark that had stood for nearly 100 years since 1928. Friday’s 80-degree mark also set a new all-time March high for the city. Burley hit 78 degrees on both Wednesday and Thursday, breaking the March 18 record set in 2004 by 6 degrees and tying the March 19 record.

Challis also had a record-breaking stretch, setting or tying records from Tuesday through Friday. The city hit 75 degrees on both Thursday and Friday — with the latter becoming Challis’s new all-time March high, edging past the previous record of 74 degrees.

Rexburg hit 76 degrees on Wednesday, Thursday and Friday — destroying the previous record highs for March 19 and March 20 by a stunning 12 degrees each day. Those previous records — 64 degrees — were set in 2007 and 2015. Wednesday’s 76-degree high also shattered Rexburg’s March 18 record of 68 degrees, set in 2017, by 8 degrees. During any normal week, that alone would have been remarkable. This past week, it barely registered.

The warmth isn’t going away for the next couple of days, at least. The National Weather Service said near-record highs are likely again in East Idaho on Tuesday, March 24, and Wednesday, March 25, with temperatures well into the 70s expected in much of the region.

A brief cooldown is expected Thursday and Friday before temperatures climb back into the 70s Saturday through Monday — meaning East Idaho could be flirting with records again heading into April.

Making all of this more alarming — no significant precipitation is in the forecast in East Idaho for at least the next seven days, deepening a precipitation deficit that has been building since January. The weather service said this has been the warmest and driest winter in East Idaho in recent memory — and the records set this past week are the exclamation point on a season unlike any other.
