The Hazardous Weather Outlook from the National Weather Service, Norman Forecast Office, as of 11:55 a.m. Monday, shows, “A few strong thunderstorms are possible this afternoon and tonight, mainly between 3 p.m. and 9 p.m. across northwest Oklahoma. No severe weather is expected through tonight.”
The discussion reads, “Through mid-afternoon, deep moisture will continue to spread north across the region. The combination of abundant moisture, weak instability, and an approaching mid-level trough will allow for mainly elevated showers and perhaps a few storms to occur through early this afternoon, especially southeast of Interstate 44. Due to weak instability, no strong or severe storms are expected through early this afternoon. However, locally heavy rainfall of 1 to 2 inches may occur.
“Between 3 p.m. and 9 p.m. today, a few strong thunderstorms may redevelop near and ahead of a dryline and cold front across northwest Oklahoma. These storms are not likely to be severe due to weak instability, but may produce hail to nickles and wind gusts up to 50 mph. Additional showers producing heavy rainfall will likely continue across southeast Oklahoma.
“After 9 p.m. this evening, additional showers and storms will likely develop along and ahead of a cold front. Due to weak instability, severe storms remain unlikely. However, a few storms may produce heavy rainfall of 1 to 2 inches, hail to nickels and gusty winds to 40 mph.”
“Other hazardous weather,” shows, “Locally heavy rainfall of 1 to 3 inches which could cause flooding in a few locations may occur this afternoon and tonight, especially over parts of southern and southeastern Oklahoma.”
The “Days Two through Seven, Tuesday through Sunday,” states, “A few thunderstorms may linger across parts of southern and southeastern Oklahoma and western, north Texas Tuesday into Tuesday night. No strong or severe storms are expected Tuesday or Tuesday night.
“Another system may bring additional chances for thunderstorms to the area on Friday.”
