The Texoma area is expected to see moderately cooler temperatures and daily rain chances throughout much of the week as a weather system makes its way across the central U.S. and into the region.


National Weather Service Meteorologist Lamont Bain, of the agency’s Fort Worth Office, said a south-moving front is expected to arrive in Texoma by the middle of the week and bring daytime temperatures down as low as the mid 80s, while also driving rain chances as high as 60 percent. The expected cold front comes after triple-digit heat scorched Texoma and much of the state in mid- and late-July, elevated the risk of grass fires and prompted many Texas counties to issue burn bans.


“We’ve got a cold front that right now is slowly sliding through the northwestern reaches of Kansas,” Bain said Monday. “As most summertime fronts move, it will be slowly headed to our area and probably won’t arrive into North Texas, specifically the Sherman-Denison area, until late Wednesday night and into the day on Thursday.”


NWS forecasts listed an expected high of 99 degrees and largely dry conditions for the area on Tuesday, before a 40 percent chance of showers develops overnight.


“There’s no guarantee that everyone’s going to see rain, but we should get a decent coverage of showers and storms,” Bain said of the week ahead. “Until then, we still have another day where we’ll be looking at hot conditions. Continue to exercise heat safety.”


Bain said the greatest chance for rain will likely occur between Wednesday evening and early Thursday morning. Increased cloud cover and the potential showers are expected to keep Wednesday’s high at just 90 degrees and Bain said daytime temperatures will fall even further on Thursday.


“As we head into the day on Thursday, we’re looking like we’re going to see much cooler conditions with high temperatures only into the mid- to upper 80s across the Sherman-Denison area,” Bain said.


A 20-30 percent chance for rain is likely to persist through Sunday. Bain said Monday it was too early to tell how much rain the area could receive by the week’s end but offered a possible range of a quarter inch to half an inch. And while the Sherman area received a record 17.1 inches of rain last August, Bain said rainfall totals this August would likely adhere closer to the monthly average of 2.06 inches.


“In terms of the long term trends, we are anticipating near normal or, maybe, slightly-drier conditions than normal,” Bain said.
