Alan Crone's Weather Blog: Showers, Cool Temps Cover Eastern Oklahoma

A strong storm system will be influencing the southern plains for the next 24 to 36 hours bringing showers and some thunder to the region, along with moderate to heavy rain for portions of Oklahoma.   Drought ravaged areas of southwestern OK may finally get some multi-inch rains.   We're in the running in eastern OK for showers with a few rumbles of thunder today along with cloudy and cool temperatures.    Our highs should stay in the upper 50s or lower 60s.   After this system exits the region, we're looking at the first few days of May arriving as a lamb.

The main upper level pattern will bring a strong upper level system over the state during the next 24 hours.   A surface area of low pressure will be directly under this upper air system.   Northeastern OK will be on the cool side of this system with northeast winds and temperatures in the upper 50s and 60s for afternoon highs.    Any severe weather threat later today or tonight should reside south of our area. There will be a slight chance of some localized flooding or drainage issues later today and tonight.

 We are dealing with some left-overs early this morning from last night's severe storms across part of north TX and far southeastern OK.  Our friends and neighbors in Texas had some extremely severe storms last night   These “left-overs" are moving generally north this morning into an atmosphere that will support some thunder and possibly small hail, but no severe storms are anticipated this morning across our immediate area of concern.

Short term hi-res data combined with some other model interpretations support a high chance of showers later today into tonight before leaving Tuesday morning.   This means about a 90% chance of showers later today into the evening hours, followed by some early Tuesday morning showers before the precipitation chances begin to dwindle.   We should be in a holding pattern this morning from around 7am to noon before additional showers and storms begin to expand into part of northeastern OK.   This means we may have some spots with no or very little rain for the next few hours.

  As the upper level system moves east of the state Tuesday night into Wednesday, back side flow may bring some sprinkles into the area early Wednesday morning, but this is a low probability.   Mid-level ridging will occur Wednesday afternoon into the end of the week allowing for pleasant mid-spring conditions including morning lows in the 40s and 50s followed by daytime highs in the 70s.   We should see at least 3, possibly 4 days of mostly sunny and mild conditions before the pattern changes again early next week with increasing storm chances back across the state.    This includes nice weather for the weekend.

In summary: keep the rain-gear and jackets handy today and for part of Tuesday morning.   Afternoon highs today will be in the upper 50s and lower 60s along with north winds around 10 to 15 mph, along with cloudy, cool and occasionally wet conditions, more so this afternoon and tonight.   Tuesday a few showers will remain early to midday with lows in the mid-40s followed by highs in the mid-60s.   Wednesday a few early morning clouds or sprinkles are a low possibility with low temperatures in the mid-40s and highs in the lower 70s along with mostly sunny conditions by midday to afternoon.

Thursday through the weekend will feature mostly sunny and mild weather.   Lows in the 40s and 50s will be followed by highs in the mid to upper 70s.   Storm chances will return early next week. 

Thanks for reading the Monday morning weather discussion and blog.

Have a super great day!
