National Weather Service Meteorologist B. J. Simpson says a rare weather phenomenon occurred this morning at the Twin Lakes Area. Between 4 a.m. and 6 a.m. the temperature in Mountain Home rose some 18 degrees going from 64 to 82 degrees before dropping back into the upper 60's just before 7 a.m. Local weather observer Chuck Beall at Mallard Point
reported about a 20 degree rise in a 90-minute span this morning before it dropped back."

Our t-storms are weird too. It used to be a summertime event, afternoon some thunder and lightning, rain pours for a few minutes, then it moves on. Now we get t-storms at night and storms that last, off and on, for days.
I know we had something weird happen last night with the small thunderstorm that rolled through. Usually when we have a thunderstorm, you have the rain and wind happening at the same time and then it's all done when it passes through. Well, last night was different. The storm came through with the rain and some lightning and thunder. Then it past and it was all quiet with no rain, no thunder, nothing for like a 1/2 hour. Then, all of a sudden we heard ROAR and this wind come whipping through (estimating a 50 mph wind gust). It lasted like about 3 or 4 minutes with two powerful gusts. (that reminds me I need to check the front pasture for trees down on the fencing) I've never seen anything like this in all the thunderstorms I've been through.
Yep. Rare is the new norm.
A rare heat burst hit Kansas, June 10,2011.
In 1960, the town of Lake Whitney, Texas, experienced a heat burst sending the air temperature to 140Â�°F, supposedly causing cotton crops to become desiccated on-the-spot and causing car radiators to boil over.

It’s been a busy day across the plains! With incredible hailstorms in Texas and more supercells through Oklahoma, Kansas, Nebraska, and Missouri, we thought things were winding down. Wrong! A heat burst is occurring in Northwest Oklahoma right now! This is a fairly rare phenomenon that is caused when air from a decaying thunderstorm dries and warms as it descends. When it reaches the ground, it creates a warm/hot and dry wind that can last for quite some time. Check out the Oklahoma Mesonet temperature map here, and click around a bit to look at variables such as wind speeds in that area.
A heat burst was observed at Amarillo, Texas (KAMA) during the overnight hours on 03 June 2002. The surface temperature briefly rose from 77 F (25 C) to 90 F (32 C) at 08:21 UTC (03:21 AM local time), with wind gusts to 55 mph (25 m s-1). NOAA GOES-10 3.9 micrometer shortwave InfraRed (IR) imagery (above, left) shows a region of warm ground (surface brightness ..
I could go on & on but the point I am trying to make is that they seem to be coming more frequently.
