Storms Monday June 11

A Severe Thunderstorm Watch has been issued for much of Northern Arkansas through late this afternoon. A line of thunderstorms is moving Southward through Missouri which will impact Northern Counties by about Noon. In addition, individual storms will develop ahead of this line, with a significant threat if large hail and some isolated wind gusts also possible.


The threat of storms for Central Arkansas will increase later this afternoon into the evening hours as storms begin to shift South. The Storm Prediction Center indicates a SLIGHT risk for severe storms for today with hail and wind the primary threats.


The tornado threat is overall low, however, a brief tornado cannot be completely ruled out with some of the stronger individual storms during the afternoon and early evening hours.

Strong Storms on the Horizon


Well, the latest weather models are out and they all agree that Mother Nature could bring us a good dousing sometime early next week.  Before you stop watering the lawn and washing the car, you might want to keep this thought in mind - besides the rain chances there will be a shot at some strong thunderstorms in Central Arkansas.

                                      (Weather model shows strong thunderstorms Monday at 2 P.M.)

As a weak cold front struggles to move southward Monday afternoon, there will be an unstable air mass out ahead of it in Arkansas.  If there is enough forcing present and daytime heating, we could see large hail and gusty winds develop.  When it comes to a tornado threat it appears it is slim to none at this point with the lack of strong upper level winds.





The Storm Prediction Center has taken note of this setup and issued a slight risk of severe weather for Arkansas.  If you're not familiar with slight risk outlook, it just means that well-organized severe thunderstorms are expected but in relatively small numbers/coverage.

No matter what SPC has to say about our weather, we'll continue to monitor the severe threats late Monday.  Be sure to keep it tuned to FOX 16 News for the latest on this developing story.

Drought Conditions worsening in Arkansas

The recent dry weather is beginning to take its toll on Arkansas with drought conditions spreading throughout the State. As of May 25th, most of Arkansas was considered "dry" with Northeast Arkansas in moderate drought according to The U.S. Drought Monitor, which tracks drought conditions across the United States.


The latest drought monitor analysis released the week of June 7th now shows most of Arkansas in the moderate drought category


Rain chances will go up for the early part of next week, however rain coverage is likely to be quite isolated. The seasonal drought outlook released by NOAA  (National Oceanic and Atmospheric Administration) indicates drought conditions across most of Arkansas will either persist or get worse through the Summer season.

Landspout Tornado in Lonoke County

A brief landspout type tornado touched down in Lonoke County Monday afternoon according to The National Weather Service in Little Rock. This was not a classic tornado produced by a rotating thunderstorm, but rather a landspout which is basically a waterspout over land. A landspout sometimes forms underneath a rapidly growing towering cumulus cloud away from thunderstorms on very warm and humid days. They typically form during the Summer months and are very weak and short lived compared to ordinary tornadoes. Below is a picture of the funnel taken by a storm Chaser in Lonoke County Monday afternoon.


 The storm chaser noted to the weather service that there was no thunder at the time. According to The Weather Service, there was no storm showing any signs of rotation in the area, which is why there was no warning issued.  Below is a map showing the estimated location of the landspout tornado.


According to John Robinson of The National Weather Service in Little Rock, the landspout touched down roughly 7 miles South-Southwest of Carlisle in Lonoke County near Arkansas Highway 13. There was no damage or even much in the way of any physical evidence of a tornado touchdown associated with the landspout. Given the lack of any discernible damage, the landspout is classified as an EF0 tornado with no real path length or width. An EF0 is the weakest classification of a torando with winds less than 85 MPH. The Weather Service used pictures to determine that the funnel briefly touched down. The landspout still counts as a tornado though, which brings the Arkansas 2012 tornado count to 11.


Viewing the Transit of Venus

Astronomy enthusiasts will get a glimpse of a very rare sight this evening.  The planet Venus will run its course and position itself in front of our Sun to where we are suppose to see it on Earth. Known as the "transit of Venus", this twice in a generation viewing happens every 105.5 and 121.5 years.  We saw our last transit of Venus in 2004, so this means today's sighting will be the last one until December 2117.


The question is will we see it in Arkansas?



If the transit of Venus were to occur this Tuesday afternoon we might have a hard time looking for it with all of the cumulus clouds around.  However, looking ahead in the future the cloud cover will be less and the sky should be clear enough to see the transit this evening.

According to NASA, the transit of Venus will begin at 5:09 P.M. and will go on until the sun sets over the horizon at 8:19 P.M.

If you plan on trying to take a snapshot of it with your camera just be aware that you have to careful with your eyes - they could be damaged by looking at the sun for a length of time.  The safest way to view the transit is to construct a so-called pinhole camera.

Some storms, much needed rainfall

Update:

The National Weather Service in Little Rock has reported that landspout tornado may have briefly touched down Monday afternoon in Lonoke County between Humnoke and Carlisle along Highway 13. The picture below shows the funnel, but does not show it touching the ground.


A landspout does not originate from a super-cell thunderstorm as does a regular tornado. These usually form underneath towering cumulus clouds under the right conditions away from thunderstorms. It is actually caused by the same process that causes a waterspout, but forms over land. Landspouts are usually much weaker than regular tornadoes and do not last very long. No damage was reported. The landspout does count as a tornado, and brings the total tornado count for Arkansas for the year up to 11.

A round of storms Monday afternoon brought much needed rainfall to Central Arkansas, with a few reports of severe weather. Storms were not as strong as Sunday, but some spots were hit by hail and some strong wind gusts. Below is a map of storm reports Monday followed by the descriptions of the reports.

The storms did bring much needed rainfall to many parts of the State over the last couple of days. Below is a map of rainfall amounts around the State since Sunday morning.



North Little Rock broke its daily rainfall record for the day with 1.36". 1.15" of that rainfall fell in a single hour. Our FOX16 Weatherbug stations across Central Arkansas also reported some decent rainfall totals in a few spots Monday.


The wetter pattern will not last as drier air moves in for the middle of the week behind a weak front. Rain chances will drop to around zero for the rest of the week with afternoon showers not returning until early next week.
Numerous thunderstorms brought hail and some strong wind gusts to the Northern half of Arkansas Sunday. No major damage was reported, but some large tree limbs were brought down and hail was larger than Golf Ball size in a couple of locations. Below is a map of the damage reports from Sunday.


 One of the hardest hit places Sunday was the town of Shirley in Van Buren County, where strong winds brought down numerous trees and caused some damage. The National Weather Service determined straight line winds of 75 MPH were responsible. Below is a complete list of severe weather reports from Sunday June 3rd.
