Thursday 630pm update: NWS has issued a Severe Thunderstorm Watch for the southern edge of the area. Watch is in effect until midnight, but severe threat will end well before then for our area. Any severe weather in the next few hours looks to be rather isolated. We’ll see a better chance Saturday afternoon.
Thursday 4:30pm update: Things have been quiet across most of the Arklatex during the past few hours. A boundary that represents some drier air at the surface is rapidly approaching the I-20 corridor and once it clears an area will shut the window on any chance of severe storm development this evening. We still have a very low end shot for a strong storm or two over the extreme southern parts of the area in deep ETX and NW LA south of I-20. We have no watches or warnings in place as of this writing.
Our next round of severe weather will return Saturday. SPC indicates that we will once again have a slight risk. All severe weather threats will be possible with the threat probably highest Saturday afternoon. You can see in the video above that Futurecast shows that the threat of showers and thunderstorms will continue through the weekend and into Monday. Rainfall totals could exceed 4″ in spots during this time.
Thursday 2:30 pm update: Showers and thunderstorms as you can see from the loop from Pinpoint Doppler below have shifted to the eastern edge of the area and are moving to the east. Turns out that the scattered showers and thunderstorms that we had this morning has so far prevented the development of stronger storms for our area. There is still a chance we could see some new development in the next few hours near the TX/LA line in a line from Texarkana to Longview. This line, if it does form, will be our last shot at thunderstorms this afternoon. Stay tuned.
Thursday 10:30 am update: A storm in McCurtain County, OKlahoma has dropped pea sized hail in Idabel. It will be moving into Sevier and Howard counties just before 11 a.m. We don’t have any watches or warnings.
Thursday 8:00 am update: The Storm Prediction Center has dropped the slight risk from southern Arkansas given the rain ongoing there this morning. The slight risk area for east Texas and Louisiana remains in place with a round of severe weather expected late this morning into the afternoon.
Thursday 5:00 am update: We did see a few severe thunderstorm warnings this morning for large hail. As of now we don’t have any watches or warnings in effect. It appears between now and 8 a.m. most of the thunderstorms will be across Oklahoma, northeast Texas, and Arkansas. These will produce frequent lightning but will likely stay below severe limits. Short range forecast models continue to show our severe weather threat ramping up around noon with storms continuing through the afternoon and evening. See the latest radar and loop futurecast below.
High temperatures today will be in the low/mid 70s with a breezy south wind.
Thursday 1:15 am update: SPC releases the latest severe weather outlook for today. They indicate a slight risk with risk probably highest over SC AR and NC LA east of Shreveport and Texarkana. All severe weather threats possible including up to golf ball sized hail and a tornado or two.
Thursday 12:45 am update:
Strong storms continue to develop and move northeast across parts of the Arklatex. The strongest storms are now moving out of NE TX into SW AR. The main concern from this activity will be the potential for hail. A storm now crossing the Red River could drop some hail between Ashdown and Ogden, AR. Hail will continue to be the main issue during the night tonight.
