Area forecast discussion, Jul 9, 2:33 PM CDT, 2 hours 22 minutes before
Area Forecast Discussion National Weather Service Norman OK 233 PM CDT SAT JUL 9 2016 .DISCUSSION... Determining rain chances over the next several days is the challenge of the day. Summer heat will continue. Before midnight tonight, believe a few thunderstorms will remain across the area, though storm coverage should be rather low due to weak subsidence behind a mid/upper trough that is over southeastern Oklahoma. Generally only went 10-20% rain chances this evening with higher chances 40-90% this afternoon near the Red River east of Wichita Falls. Current complex of storms along the Red River near and east of I-35 as of 230 PM will continue to push south into north Texas. Believe a few additional storms may form on lingering outflow boundaries mainly southeast of I-44 where deepest moisture exists with precipitable water values 1.7-2". Any storm should be slow moving which can dump a few inches of rainfall in small areas. Severe potential is low, though cannot rule out damaging winds up to 60 mph if storms occur as daytime heating supports DCAPE values of 1000-1800 J/kg. After midnight tonight, a few storms may linger closer to the departing mid/upper trough and where moisture convergence may be stronger in southeastern Oklahoma. A complex or two of storms may occur across the High Plains and get into far western Oklahoma and far western north Texas, though it appears the greater chances for this to occur will be over the Panhandles. Sunday looks to be another hot and humid day with even lower rain chances than today as the cap strengthens. Head indices may approach 105 degrees in some areas. Did not issue a Heat Advisory as not sure how high surface dewpoints will be. Cannot completely rule out a stray afternoon and evening storm, but chances appear to be too low to mention, generally below 15%. Sunday night into Monday, there is a slight signal that storms over the High Plains may make into the area, but confidence is very low. Hot and humid conditions will continue. Surface winds will increase on Monday. Monday night through Friday, no signficant changes in the weather pattern are expected with continued hot weather along with low chances for showers and storms. A weak front may approach Kansas or northern Oklahoma during this time frame which could serve as a focus for higher rain chances. Chances of widespread rainfall remain low during this time frame.
