Oklahoma City is heading into Sunday, September 27, with summer still refusing to leave quietly. The city is headed for a sunny 91-degree afternoon after a small early-morning chance of showers or thunderstorms.

According to data from the National Weather Service, the September 27 forecast gave storms a 30% chance through 3 a.m. CDT. After that, skies should clear, south winds should run 3 to 8 mph, and temperatures should climb through the day, peaking in the upper 80s by late afternoon.

Heat Lingers Before The Pattern Breaks

Sunday night stays partly cloudy with a low around 70, followed by a mostly sunny Monday near 90. Monday carries a 20% chance of showers, so most daytime plans should remain dry, though the air will still feel more like late summer than fall.

The bigger change arrives Tuesday night. Tuesday reaches about 90 with a 20% rain chance during the day, then storm odds rise to 50% Tuesday night; Saturday's Hoodline forecast had already flagged a warmer Sunday and building storm chances, but the new outlook now points to a wetter, cooler stretch beginning midweek.

Rain Chances Peak Wednesday And Thursday

Wednesday is forecast to bring showers and thunderstorms, with a 70% chance of precipitation and a high near 84. Rain and storms remain likely Wednesday night, then continue Thursday with a 70% chance and a high around 80.

The National Weather Service says the developing moisture pattern could support beneficial rain from Tuesday through the end of next week, with a risk of heavier or flooding rainfall in parts of the region. No watches or warnings are listed for Oklahoma City at this time, but residents should take thunder seriously and head indoors when storms move in.

Cooler Air Finally Shows Up

Friday brings a high near 78 with a 40% chance of showers and thunderstorms, while Saturday rebounds slightly to about 80 with a 20% chance of showers. The week starts with shorts weather and ends with a much more convincing argument for keeping a light jacket nearby.
