NEXT ADVISORY
————-
NEXT COMPLETE ADVISORY…800 PM PDT.

There are indications in weather model guidance that remnant moisture from Simon could stream northeast into the Southwest United States late next week. Such a solution would result in increased precipitation chances. Confidence in such an event is very low and thus any sort of forecast accuracy at that range is also low. We’ll keep a close on eye on the potential for increased rain chances from Simon’s remnants down the road. For now all we can do is hope that Simon eventually says it wants to bring rain to our drought-stricken state.

North & Central TX Wind Damage Analysis

The National Weather Service in Fort Worth has put together an information package containing information regarding wind speeds in the hardest hit areas from Thursday’s storms. No tornadoes have been confirmed or suspected in causing damage on Thursday. All indications point to straight-line winds to the cause of all the damage across the D/FW Metroplex and Waco. Wind gusts up to 90 MPH caused significant wind damage and left over 200,000 without power. This event is a reminder that straight-line winds do produce damage equivalent to weak tornadoes. The difference is the wind blows in a single direction verses in a twisting fashion.

The Fort Worth Radar captured the high winds fairly well since it was within a few miles of the highest winds in Arlington and parts of Dallas County. Here’s an animiation created from the Natinoal Weather Service in Fort Worth of the radar data along with a few of the strongest wind reports.

5:45 PM Severe Weather Update

2014-10-02_17-45-13

A line of strong to severe thunderstorms continues to progress east across North and now parts of Central Texas. Behind the line of storms skies quickly clear and its a fairly beautiful late afternoon. I’m assuming most of you have already seen some of the wind damage photos out of the D/FW Metroplex so I’ll spare you from rehashing all of that. At 5:45 PM the leading edge of the storms was alone a line from 10 miles east of Paris, Wills Point, southwest to Ennis. From there a broken line of storms extends to just west of West, TX to Evant. These storms are moving east at 30 to 45 MPH. The strongest storms in Northeast/East Texas have a continued history of producing wind gusts up to 80 MPH with significant wind damage. Hail up to the size of golfballs has been common with the strongest hail cores. The largest hail we saw earlier was near baseballs in Podner and Denton but that was while storms where discrete and not linear.

I see little reason why these storms won’t continue to move east for the next several hours. Continued development to the south along the cold front is expected and Central Texas will start dealing with more severe weather within the next hour or two. Severe weather in the form of large hail and damaging winds will be possible with the strongest storms. With so many warnings in effect we simply cannot share them all. The best way to keep up with storms in your area is to use the local weather pages and our interactive radar at www.texasstormchasers.com/radar

Severe Storm Warning: Bosque, Hill, McLennan Counties till 6 PM

Severe Thunderstorm Warning for parts of Bosque, Hill, and McLennan Counties in Central Texas. A severe thunderstorm with supercellular characteristics is located 10 miles southwest of Lake Whitney State Park and is moving east at 35 MPH. This storm is capable of producing golf ball size hail and damaging winds over 60 MPH. This storm should cross Interstate 35 near Abbott and West passing between Hillsboro and Waco.
