Up to 4 inches of rain possible, Flash Flood Watch in effect
Yet another unusual summertime cool down has descended on Oklahoma bringing very good rain chances again. During the day Tuesday, some showers and storms are possible but mainly for western Oklahoma. However as we move into Tuesday night and into Wednesday, rain chances go up for the entire state. Showers and occasional thunder storms will be on the increase starting Tuesday night lasting through the day on Wednesday. Expect rounds of showers and storms that could be heavy at times. Severe weather is not likely, but heavy rain could cause flooding problems. Local street, creek, and river flooding will be possible in areas that see significant rain. This is why a Flash Flood Watch exists through Wednesday evening for central and northern Oklahoma. It is very hard to tell how much water is covering a roadway, and it does not take much water to cause problems for vehicles. Turn around, don't drown!The Heaviest rainfall totals are likely in central to northern Oklahoma where around 2-4 inches of rain is possible with isolated higher amounts. Elsewhere will still see decent rain, especially by summer standards, with around 1-3 inches possible.Rain chances last through Wednesday evening before slowly clearing out as we head into Thursday. Some lingering rain is still possible into Thursday morning, but likely not as heavy. High temps on Wednesday and Thursday will likely not make it out of the 70s.All of this cool and rainy weather is being caused by strong dip in the jet stream (strong winds near the level at which most commercial planes fly) that is very common during the spring, fall, and winter months. Summer is usually a time when the jet stream is quiet in our area which leads to days and months of hot and dry weather. This summer however, the jet stream has been much more active which has led to these very welcome rounds of rainy and cooler weather. Enjoy it while it lasts!
