Alan Crone's Weather Blog: Taste Of Fall Weather Ahead

A strong cold front is moving southward this morning with some shower and thunderstorm activity along and behind the boundary.   A few strong storms may persist until 7am across south-central or east-central OK.   As the front moves southward, north winds will increase at 10 to 20 mph and some showers and storms may persist for a couple of hours behind the front before ending from the north to south by this morning.   Morning clouds may linger through early afternoon before breaking from the north to south.   Daytime highs will reach the mid and upper 70s today behind the front along with drier air at the surface moving into northeastern OK this afternoon and evening.   Friday night football games will be played in the lower 70s and dropping into the upper 60s tonight along with north breezes and pleasant conditions.   A taste of fall weather will move across the entire state with this weekend’s temperatures below the seasonal averages.

This past week we’ve been well into the upper 90s before the first front arrived with storms and temperatures in the 80s.   This morning’s front is different.   The air-mass behind the boundary is characterized with lower surface dew points and cooler air.   This modified Canadian air-mass will slide across the Missouri Valley into northeastern OK this evening allowing for wonderful weekend temperatures across the state.   Reading’s tomorrow morning will start in the lower 50s along with northeast winds at 10 mph and daytime highs in the lower 70s north and mid-70s south.   Sunday morning lows may see a few spots in the upper 40s in the valleys of northeastern OK with the metro back into the lower 50s.   East to southeast winds will return Sunday allowing daytime highs to move into the upper 70s.   Mostly sunny conditions will be expected across most of eastern OK this weekend but a few clouds and small showers could develop across part of northwestern OK Saturday.   This chance remains very low.

Our pattern will undergo another change next week.   This weekend will feature a strong trough across the east and a ridge in the west helping to create a northerly to northwesterly flow aloft.   Next week a pacific trough is expected to develop and will eventually carve out of a southwesterly flow from the desert southwest into the central U.S.  This pattern will bring a slow increase in low level moisture back to the state along with gradually warming temperatures for the middle to end of next week.   The pattern should also bring a storm system or two near the state by the end of next week.  

Enjoy this wonderful early taste of fall-like weather moving across the area today and this weekend.

Have a super great day!
