TYLER, TX (KLTV) - An outflow boundary from storms across Arkansas yesterday has moved into East Texas and could help to fire a couple of storms later this afternoon. At the same time a ridge of high pressure in the upper levels of the atmosphere will begin to build back into East Texas. This high pressure should keep most of East Texas dry today with the one exception being across our far southern counties where from Crockett to Lufkin to Hemphill we could see an isolated storm Friday afternoon. It is across our southern counties where the outflow boundary will have the best chance of sparking a storm or two.
This ridge will of high pressure will stick around through Sunday keeping most of East Texas dry and warm. Some slightly drier air will mix down during the afternoon hours so the heat index will not be quite as hot as we have seen this week. This should also allow for nighttime temperatures to dip down into the middle to upper 60s.
As we head towards Memorial Day, it looks as though most of East Texas will continue to remain dry. The ridge of high pressure will begin to break down just a bit so we can't rule out a pop up storm developing but I would not cancel those outdoor barbeques just yet.
