It took until the mid afternoon hours but the thunderstorms projected from last night indeed have fired as that upper level low that we’ve been discussing will continue to drift to the southwest from Wyoming keeping the heaviest rain along the Front Range and the Rockies.
Favored areas for rain this evening appear to be west of highway 281 and north of I-80. Active thunderstorms are slowly drifting westward due to the circulation of that low. Because of the slow movement some of the strongest storms could lay down an inch of rain over areas. We will expecially watch for higher amounts along and to the north & west of a Grand Island to Cozad line. This is where the most widespread coverage is setting up. Severe weather is not anticipated.
We’lll check back with you after the 6 pm news.

A strong upper level low pressure system with its associated cold pool of air conitinues to drift south out of Canada, tracking along the front range. Numeric forecasting models are now placing the energy associated with this sytem farther wes. With the modest amount of rain we’ve seen today that is verifying, so we are making some alterations to the forecast.
I wouldn’t put the umbrella away all together, after all ,this is a fairly potent system and impulses sometimes not reflected by the forecast models can get spun out reeking havoc with a forecast put out in good faith. I don’t think we’ll be seeing much in terms of rain tonight and only scattered thunderstorms for tomorrow but we’ll stay on our heels in case some changes develop.
Flash Flood Watches that were in effect have been dropped as the heaviest rain will be mainly out toward the panhandle and the High Plains.

A thunderstorm complex continues to push into the Tri-Cities area producing wind gusts up to 50 mph near Arcadia in southern Valley County and 47 mph at Evelyn Sharp Field near Ord.
The integrity of this complex will maintain itself, though will continue to weaken as it marches to the southeast. Gusty winds up to 50 mph along with localized heavy rain and possibly some small hail is possible but not expecting anything particularly severe. Brief bursts of stronger winds could occur with these storms several minutes before it actually begins to rain.
At this hour it appears that these storms will sweep into Howard, Nance, Merrick and at least northern portions of Hall.
As you watch the Olympics tonight, our Sky Alert will alert you any warnings should they occur.

China’s finger print is on just about everything in the world these days. They influence the global economy, oil reserves, they’re sparing no expense in image control before the Bejing Olympics and now are shelling out millions more in an attempt to control the uncontrollable……the weather.
In the days prior to the opening ceremony, rockets launchers have been trained on passing clouds over their country. China, it seems, is one of the worlds largest practitioners of cloud seeding. The idea is to try to enable rain to occur BEFORE the games–not during it–thus clearing out the air polution while preventing later rains from postponing some of the events.
Sound farfetched? Well, cloud seeding in the past has been tried around the world, including the U.S., producing mixed results. The National Academy of Sciences has said that there is no conclusive proof that cloud seeding works.
Cloud seeding can’t create clouds. Chemicals such as silver iodide or salt produce ice crystals, nuclei that attract supercooled water droplets enhancing a clouds ability to produce rain or snow. There is no question that ice crystals are produced, that’s measurable. But its the processes leading to rain reaching the ground which apparently are much more complex making weather control as unpredictable as well…………………the weather.
It should be an interesting experiment. One would think pulling off a neatly organized Olympic event would be daunting enough for a country. Controlling the weather on top of it should prove to the world just how ambitious the Chinese really are.

There were some unbelievable numbers posted across the state this weekend as we all spun on the barbeque spit over hot coals , or so it seemed. Imperial boasted the highest temperature…111 degrees. Wow!
“But it was dry heat,” you say. So is an oven, but you don’t stick your head in it.
I was on the opposite end of the state, in Omaha, which mirrored how I would imagine an Amazonian rainforest to feel. Instant sweat thirty seconds after you went outdoors, with dewpoint temperatures in the upper 70s. Not to be out done was Falls City with an 82 degree dewpoint and an actual temperature of 96 making it feel like 120. That is what Malaysia feels like.
Fortunately, most of us got a break from the heat today. The Heat Advisory expired at 7 pm for southeast Nebraska where temperatures climbed to 103 in, yes, Falls City. Lest we feel sorry for ourselves however, I was checking out the conditions in eastern Oklahoma this afternoon. The town was Tahlequah and the temperature hit 106 with a dewpoint of 77 making it feel like…(Drum roll) 128 wopping degrees. Be careful, that melted ooze you about stepped in is actually Tahlequah.
Perhaps we should do our friends in the Okie State a favor and turn our window fans to the south tonight.

Severe Thunderstorm Watch remains in effect until 3 am. A strong line of storm continues to march out of the sandhills into a unstable, moisture rich enviroment. Low level jet stream winds nose too far south so there is some question as to how far the line will maintain itself. Counties to the north of Grand Island appear targeted for the threat of strong winds and heavy amounts of rain however outflow from these storm could create addition storms ahead of the line.

Thunderstorms are popping up in random locations mainly to the north of Interstate 80, with the greatest concentrations around Broken Bow and Columbus. As storms continue to evolve and become more widspread this evening heavy amounts of rain will be layed down over areas already saturated with rainfall from Monday and Tuesday of this week.
Abundant moisture is available to these storms and widespread rainfall of 1 to 2 inches is likely with some locations picking up as much as 4 inches. With some of these storms rainfall rates of up to two inches per hour is possible.
A Flash Flood Watch is in affect and people should be aware that flooding is a pretty good bet across central Nebraska and should be prepared to take action.

Like clockwork, storm have waited until after the midnight hour to merge and push through the Tri-Cities region. Heavy rains with a line of storms dropping from north to south through the region have amplified flooding problems created earlier in the afternoon.
Flash Flood Warnings remain in effect for parts of central Merrick, northeastern York, northeastern Hamilton and Polk Counties until 5:15 am. Addtional warnings for the rest of Hamilton and southwestern York Counties until 6:30 am. By Doppler estimates two to four inches have fallen in these areas with an addition one to two inches possible before the night ends. Near Gresham in York County 3.75″ has been estimated by law enforcement.
With the leading edge of the storms settling into Kansas, the heaviest fo the rain is over but light to moderate rain will continue for the next couple of hours adding to the rain gauges.
Natures late night storm schedule is getting kinda old. I think we could all use a full night of uninterupted sleep.

We have got to stop meeting like this. Our never ending soap opera of thunderstorms continues this evening……again. Storms fired out west in Perkins and Keith Counties reportedly dropping a couple of weak tornadoes late this afternoon, and now storms have merged into a line and it appears another thunderstorm complex producing winds of 60 mph and hail will track across Dawson, Custer and Gosper counties through mid evening.
These storms are moving into an instablility axis and the southern flank of these storm could intensify along the Kansas line in the next couple of hours as well.
A Severe Thunderstorm Watch is in effect for southwest Nebraska and two tiers of counties to the north of Grand Island until 11 pm. Major towns include Kearney, Lexington, Broken Bow, Ord, Loup City, Cozad, Holdrege, Beaver City, Minden and Alma.
Storms should continue to support strong winds and hail through the eastern portions of the watch. We will continue to monitor as the line moves into a somewhat drier airmass thereafter.
