Severe Setup

A swirling area of low pressure in the upper levels of the atmosphere over the Four Corners and southern Rockies has run into a "road block" in the pattern over the East, namely, an "omega block" of high pressure, causing the low to stall and become cutoff from the jet stream.

The flow between the two systems has transported moist air northward through the Plains, while lobes of energy eject northeastward around the upper-level low.

Thus you have moisture, instability, wind shear (change in wind direction with increasing height) and a source of lift (dryline - a boundary between dry southern High Plains air and moist air) neede for severe thunderstorms.

Severe Weather Forecast

Saturday

Scattered severe thunderstorms are likely to flare up by late afternoon and evening from western Texas into western Kansas.

Large hail (some to baseball size or larger) is the greatest threat, but some tornadoes are also possible, as well as damaging straight-line winds.

Overnight, an expansive line of t-storms from Kansas to west-central Texas is expected. Some of these storms may be severe with hail and high winds, but flash flooding is likely to become the most serious threat.

Cities: Abilene | Amarillo | Dodge City

Sunday

Thunderstorms with heavy rain and flash flooding will likely be ongoing from Kansas to central Texas.
Any severe t-storms Sunday are most likely in parts of north and central Texas.

Large hail, damaging winds, and possibly a tornado are the threats with any of these t-storms in Texas.
Clusters of t-storms will continue overnight from Kansas to the Texas Coast, with a serious threat of flash flooding and a few severe storms as well, particularly closer to the Texas Coast.

Cities: Okla. City | Dallas | Austin | San Antonio | Houston

Monday

Thunderstorms with flooding rain may be ongoing in the morning from central Nebraksa to central and east Texas.

The best chance of severe t-storms will be in parts of central and southeast Texas, with hail, high winds and a few tornadoes possible.

Overnight, another cluster of t-storms is possible in parts of central or southeast Texas. Some of these storms may be severe with hail and high winds, but flash flooding may be the most serious threat.

Cities: Dallas | San Antonio | Houston | Corpus Christi

There are indications that the blocking pattern begins to break down into next week, which will allow for the once cutoff low to gradually weaken and progress eastward.

Friday's Storm Reports

As of Friday night, tornadoes have been reported by storm spotters in Eads, Colorado and near Guymon, Oklahoma. Storm chasers reported multiple additional tornadoes in the Oklahoma panhandle. There were 10 reports of tornadoes, according to NOAA's Storm Prediction Center.
