3:50pm - National Weather Service saying after a conference with Storm Prediction Center..no Tornado Watch is anticipated in North Texas at this time. Conditions are just too weak to borderline to produce widespread severe weather. Still could be a few strong storms especially east of I-35E and south of I20 throughout the next 2-3 hours.
345pm - heavy rain moving thru Fort Worth down to Cleburne into Hill County. Lightning tracker showing only 14 cloud to ground lightning strikes with this rain. Gusty winds 20 to 30 mph with heavy downpours but nothing severe.
3:30pm - Line of rain/storms approaching Fort Worth. Line extends south through much of Johnson County and into western Hill County. This will mainly be just heavy rain for a period of 15-20 minutes along with some lightning & gusty wind. Wind gusts so far have been 20-30mph. Still a slight risk for severe weather, but nothing severe so far.
3:22pm - Heavy storms also affecting western Hill County. These have the greatest instability and spin to work with..although nothing severe right now...just brief heavy downpours.
320pm - From NWS, Line of showers/storms moving through eastern Wise and western Tarrant County now. Nothing reported except for brief periods of locally heavy rain. Gusty winds are likely associated with the leading edge, but surface observations only show 20-30 mph gusts in western Tarrant County

After that just some left over rain.
253pm - storm are merging over Somervell and Bosque county leading to some heavy rain near Glen Rose and Meridian. Nothing severe, but storms showing some signs of strengthening.
238pm -Significant Tornado Parameter shows where we have the best available moisture & spin in the atmosphere to see supercell thunderstorms produce tornadoes. You can see that the best signs of that is well south of the Metroplex…down toward the Waco area. Certainly the farther south you live, the better chance to see strong to severe & rotating storms. Again, there is plenty of spin in the atmosphere today, but lackluster instability. ~Jeff Jamison
230 pm - Radar snapshot as of 227pm. Lots of spotty showers and storms developing ahead of line. Nothing severe at this time.
215pm - A few lightning strikes being noted in Hunt County north of Greenville and some individual storms trying to develop in Navarro County. We will have to watch this closely out ahead of the line of storms. But dewpoints are still in the 50s. 60s dewpoints mean the air is more humid and more likely to produce severe weather. The new Severe Weather Outlook from the Storm Prediction Center still has areas from DFW south in the Slight Risk for severe weather today.
2pm - Showers and a few claps of thunder have been moving thru the metroplex, but nothing severe so far. There is a line of showers and storms that has moved thru Mineral Wells and Stephenville that is rapidly approaching the metro area. This may intensify but be thankful for the cloud cover and cooler temperatures. That may limit our severe weather intensity.
